Refinancing · TARA AI Calculator
Personal Loan Balance Transfer — Savings Calculator (with TARA AI)
Most balance transfer pitches show you a lower interest rate and stop there. This calculator does the boring math your bank won't — foreclosure penalty on the old loan, processing fee on the new loan, 18% GST on both, and break-even against your remaining tenure. Plug in your numbers and TARA AI gives you the rupee answer in 60 seconds: switch, marginal, or stay put.
Calculator cheat sheet — minimum inputs for refi to pay off
| Your outstanding | Minimum rate drop | Minimum tenure left |
|---|---|---|
| Below Rs 2,00,000 | Skip — BT rarely works at this size | N/A — friction ~5.9% almost always exceeds savings |
| Rs 2,00,000 — Rs 5,00,000 | Minimum 4 percentage points | Minimum 30 months remaining |
| Rs 5,00,000 — Rs 10,00,000 | Minimum 3 percentage points | Minimum 36 months remaining |
| Above Rs 10,00,000 | Minimum 2 pp (1.5 pp if processing fee waived) | Minimum 36 months remaining |
Friction cost = ~3% foreclosure penalty + ~2% processing fee + 18% GST on both. Most Indian personal loans are fixed-rate, so RBI's 7 May 2014 floating-rate foreclosure ban doesn't cover them — budget for these fees.
How the balance transfer math works (the formula)
Refinancing isn't magic — it's a 5-step calculation TARA AI runs in 60 seconds. Here's exactly what goes into it.
Compute monthly saving
Run the exact reducing-balance EMI on both loans, then subtract.
monthly_saving = old_EMI − new_EMI
Where P = outstanding principal, r = monthly rate (annual ÷ 12 ÷ 100), n = remaining months. No rounding shortcuts — compute to the rupee.
Compute total nominal saving
Multiply your monthly EMI saving across every remaining month of the loan.
We compare nominal rupee totals — we don't discount to present value. NPV-adjusted savings will be 8–15% lower than the nominal figure, depending on your personal discount rate.
Compute the friction stack
Three real, payable costs sit between you and the cheaper EMI.
processing_fee = 1–3% of new loan
gst = 18% on (foreclosure + processing)
total_friction = sum of all three
Most Indian personal loans are fixed-rate, so the RBI 7 May 2014 ban on foreclosure charges (floating-rate retail only) does not apply. Budget the penalty.
Compute break-even months
How many months of cheaper EMIs you need just to recover the friction.
Total friction is roughly 5.9% of outstanding (3% foreclosure + 2% processing + 18% GST on both). If break-even is more than 50% of your remaining tenure, treat the switch as marginal — the surplus runway is too thin to absorb a job change or rate hike. If break-even exceeds your remaining tenure, don't switch.
Net rupee outcome
The single number that decides it. Subtract the friction stack from the total nominal saving.
Positive net saving means the switch puts rupees in your pocket. But there's a second gate: if friction cost is more than 50% of your total nominal saving, treat the switch as marginal even when the net is positive — the margin of safety is too thin once you adjust for NPV and tenure risk.
TARA's verdict thresholds
- SWITCH — net saving is greater than one month of new EMI.
- MARGINAL — net saving is between zero and one month of new EMI.
- DON'T SWITCH — net saving is below zero.
One month of new EMI is the safety buffer — it covers NPV drift, a possible part-prepayment lock-in, and the small CIBIL dip from the hard enquiry. Anything thinner than that and you're working for the lender, not for yourself.
Worked examples — 6 calculator outputs
Six real-world balance transfer scenarios at different outstanding × rate-drop × tenure breakpoints. Each panel shows the inputs, the math TARA AI runs, the friction load and the net rupee outcome — exactly like a calculator's output screen. Look for the scenario closest to your loan.
Scenario A · Small loan · 6pt drop · 18 months left
Outstanding Rs 1,50,000 · Rate 20% → 14% · Tenure left 18 months
| Old EMI | Rs 9,714 |
| New EMI | Rs 9,287 |
| Monthly saving | Rs 427 |
| Total EMI saving over 18 months | Rs 7,690 |
| Foreclosure penalty (3% of outstanding) | Rs 4,500 |
| Processing fee on new loan (2%) | Rs 3,000 |
| GST 18% on both fees | Rs 1,350 |
| Total friction | Rs 8,850 |
| Break-even | 21 months (longer than tenure left) |
| Net outcome | Rs -1,160 |
TARA's take: A 6-point drop looks dramatic, but on Rs 1.5L over 18 months the friction (Rs 8,850) eats the entire EMI saving (Rs 7,690). Small principal can never absorb a 5.9% friction load in 18 months — finish this loan, and switch only if you genuinely cannot service the current EMI.
Scenario B · Common case · 5pt drop · 24 months left
Outstanding Rs 3,00,000 · Rate 18% → 13% · Tenure left 24 months
| Old EMI | Rs 14,977 |
| New EMI | Rs 14,263 |
| Monthly saving | Rs 715 |
| Total EMI saving over 24 months | Rs 17,152 |
| Foreclosure penalty (3% of outstanding) | Rs 9,000 |
| Processing fee on new loan (2%) | Rs 6,000 |
| GST 18% on both fees | Rs 2,700 |
| Total friction | Rs 17,700 |
| Break-even | 25 months (just past tenure) |
| Net outcome | Rs -548 |
TARA's take: This is the textbook trap. Five points of rate gap feels like easy money, but on 24 months left the math comes in essentially flat — Rs 548 negative after friction, with break-even one month after the loan would have closed anyway. Negotiate a rate reduction with your existing lender instead.
Scenario C · Mid loan · 4.5pt drop · 36 months left
Outstanding Rs 5,00,000 · Rate 16% → 11.5% · Tenure left 36 months
| Old EMI | Rs 17,579 |
| New EMI | Rs 16,488 |
| Monthly saving | Rs 1,091 |
| Total EMI saving over 36 months | Rs 39,258 |
| Foreclosure penalty (3% of outstanding) | Rs 15,000 |
| Processing fee on new loan (2%) | Rs 10,000 |
| GST 18% on both fees | Rs 4,500 |
| Total friction | Rs 29,500 |
| Break-even | 27 months (75% of tenure) |
| Net outcome | Rs +9,758 |
TARA's take: Positive net of Rs 9,758, but break-even at month 27 of 36 means you only enjoy the cheaper EMI for the last 9 months. Worth switching only if you also plan to part-prepay in months 1-12 to amplify the gain — as a pure rate-arbitrage play this is a soft yes.
Scenario D · Large loan · 3pt drop · 48 months left
Outstanding Rs 8,00,000 · Rate 15% → 12% · Tenure left 48 months
| Old EMI | Rs 22,265 |
| New EMI | Rs 21,067 |
| Monthly saving | Rs 1,198 |
| Total EMI saving over 48 months | Rs 57,481 |
| Foreclosure penalty (3% of outstanding) | Rs 24,000 |
| Processing fee on new loan (2%) | Rs 16,000 |
| GST 18% on both fees | Rs 7,200 |
| Total friction | Rs 47,200 |
| Break-even | 39 months (82% of tenure) |
| Net outcome | Rs +10,281 |
TARA's take: Big principal, long runway, but only a 3-point rate gap. The Rs 10,281 net surplus is real, but break-even at month 39 of 48 leaves just 9 months of pure benefit. Becomes a clear SWITCH only if you can negotiate the processing fee down to 1% or land a zero-foreclosure NBFC offer.
Scenario E · Tenure too short to recover friction
Outstanding Rs 2,00,000 · Rate 17% → 13% · Tenure left 8 months
| Old EMI | Rs 26,620 |
| New EMI | Rs 26,234 |
| Monthly saving | Rs 386 |
| Total EMI saving over 8 months | Rs 3,087 |
| Foreclosure penalty (3% of outstanding) | Rs 6,000 |
| Processing fee on new loan (2%) | Rs 4,000 |
| GST 18% on both fees | Rs 1,800 |
| Total friction | Rs 11,800 |
| Break-even | 31 months (4x your remaining tenure) |
| Net outcome | Rs -8,713 |
TARA's take: Classic tenure-mismatch trap. A 4-point rate drop is meaningless with only 8 EMIs left — over 80% of each EMI is already principal repayment. You'd burn Rs 11,800 in fees to save Rs 3,087. Just finish the loan.
Scenario F · Rate drop too small to matter
Outstanding Rs 6,00,000 · Rate 14% → 12.5% · Tenure left 30 months
| Old EMI | Rs 23,819 |
| New EMI | Rs 23,391 |
| Monthly saving | Rs 428 |
| Total EMI saving over 30 months | Rs 12,851 |
| Foreclosure penalty (3% of outstanding) | Rs 18,000 |
| Processing fee on new loan (2%) | Rs 12,000 |
| GST 18% on both fees | Rs 5,400 |
| Total friction | Rs 35,400 |
| Break-even | 83 months (2.8x your tenure) |
| Net outcome | Rs -22,549 |
TARA's take: 1.5 points is below the friction floor. Rule of thumb: on a 5.9% all-in friction cost you need a rate gap that delivers at least 200 bps of effective annual reduction over a 24-month-plus runway. This loan stays where it is — call your lender and ask for a 50 bps reduction instead.
Pattern read: Notice how 4 of 6 scenarios come out negative once friction is honest. Balance transfer wins are rarer than the rate gap suggests — the 5.9% all-in friction (3% foreclosure + 2% processing + 18% GST on both) is the hidden floor most calculators skip. Plug your outstanding, rate gap and remaining tenure into TARA AI to see which scenario your loan maps to.
How TARA AI runs your balance transfer calculation in 60 seconds
You don't need to dig out your sanction letter, hunt for the foreclosure clause, or build a spreadsheet. TARA AI does the whole calculation as a guided chat — input, calculation, output — in about a minute. Here's exactly what happens when you ask.
- 1
Open TARA. Say "should I do a balance transfer on my personal loan?"
Input: a one-line question in Hindi, English or Hinglish. Output: TARA acknowledges and asks for consent to read your bureau record so you don't have to type numbers manually.
- 2
TARA reads your existing loan from your shared bureau
Input: consented bureau pull. Calculation: TARA extracts your current outstanding principal, contracted interest rate, EMI, and months remaining on tenure. Output: a clean snapshot of your existing loan — no manual data entry, no guesswork.
- 3
Soft-enquiry scan across 55+ lenders for your refinance offers
Input: your profile (income, employer, CIBIL band). Calculation: a soft-enquiry sweep across partner lenders — your CIBIL is not charged a hard enquiry hit. Output: the best 3-5 indicative refinance rates you actually qualify for, not headline rates from lender websites.
- 4
Calculator runs automatically — foreclosure + processing + GST math
Input: old loan snapshot + new indicative offers. Calculation: exact reducing-balance EMI on both sides, foreclosure penalty on the old loan, processing fee on the new loan, 18% GST on both fees, break-even months, and an NPV-adjusted net saving. Output: a side-by-side rupee-for-rupee comparison — no rounding shortcuts.
- 5
TARA verdict — SWITCH, MARGINAL, or DON'T SWITCH
Input: the net rupee saving and break-even months. Calculation: verdict thresholds applied — SWITCH if net saving exceeds one month of new EMI, MARGINAL between zero and one EMI, DON'T SWITCH if negative. Output: a clear verdict with the exact rupee figure. If DON'T SWITCH, TARA opens a prepayment scenario side-by-side so you don't leave empty-handed.
When balance transfer beats prepayment — and when it doesn't
Most borrowers treat "should I balance transfer?" and "should I prepay?" as separate questions. They aren't — they're two paths to the same goal of cutting your total interest outflow. The right one depends entirely on your inputs: how much cash you have, what rate gap you're looking at, and how much tenure is left. This is a question the calculator settles objectively, not a question of preference.
Balance transfer wins when:
- ·You don't have lump-sum cash for prepayment AND can only redirect monthly cash flow toward a lower EMI.
- ·Your rate drop clears the minimum threshold for your outstanding band (4 points for Rs 2-5L, 3 points for Rs 5-10L, 2 points above Rs 10L) AND the gap is real, not a headline rate you won't actually get offered.
- ·Your tenure remaining is at least 2x your break-even months — that margin protects you against a bad-luck event like a job change or rate reset wiping out the saving.
Prepayment wins when:
- ·You have Rs 2-5 lakh sitting in a low-yield savings account or FD at 6-7%. The opportunity cost of leaving it parked is lower than the 14-18% your existing PL is charging — prepayment is a guaranteed arbitrage.
- ·Your friction cost (foreclosure + processing + GST) exceeds 50% of total nominal saving — the BT math is technically positive but too thin to absorb any execution risk.
- ·You'd fail the new lender's stricter eligibility — recent job change, FOIR already stretched, or CIBIL just under the cut-off. A BT rejection still costs you a hard enquiry hit.
TARA AI runs both scenarios side-by-side and tells you which one wins for YOUR specific numbers — not a generic rule of thumb, the actual rupee figure for your outstanding, your rate, your tenure.
Top 5 lenders for personal loan balance transfer
These are the lenders TARA AI most often quotes when running a balance transfer calculation. Rates shown are illustrative starting ranges for super-prime salaried profiles — your actual offer depends on your CIBIL, employer category, income and FOIR. Use this as a cheat sheet, not a price list.
| Lender | Starting rate (illustrative) | Rate caveat | BT processing fee | Foreclosure on existing | TARA notes |
|---|---|---|---|---|---|
| HDFC Bank | 10.5–10.85% | Super-prime salaried only: CIBIL 780+, employer category A (top corporates / listed / MNCs), net salary credit to HDFC. | Up to 1% of BT amount (min Rs 1,999, max Rs 25,000) + 18% GST | Existing HDFC PL: 4% (13–24 mo), 3% (25–36 mo), 2% (after 36 mo). No foreclosure in first 12 EMIs. | Tightest rate-band lender for BT but gatekeeps hard on employer category. If your employer is not on HDFC's A-list, expect 11.5–13%, not 10.5%. TARA AI flags this before you spend on the application. |
| ICICI Bank | 10.65–10.85% | Premium salaried: CIBIL 750+, monthly net income above Rs 75k, salary account with ICICI or top-tier employer. | Up to 2% of BT amount + 18% GST (often negotiable to 1–1.5% for clean profiles) | Existing ICICI PL: 5% of principal outstanding + GST (fixed-rate product — 2014 RBI floating-rate ban does not apply). | Most negotiable on processing fee if you push back, especially for existing ICICI savings account holders. Year-1 foreclosure on the new BT loan is 5%, so model your full tenure intent before switching. |
| Axis Bank | 10.99–11.25% | Salaried with CIBIL 760+, employer in Axis's Cat A/B list, minimum net salary Rs 50k. | Up to 2% of BT amount + 18% GST | Existing Axis PL: 5% (13–24 mo), 3% (25–36 mo), 2% (after 36 mo), all + GST. No foreclosure in first 12 months. | Sweet spot if your current lender quoted 13%+ but HDFC/ICICI rejected on employer category. Axis runs a wider Cat B list. Watch the 2% fee — it can wipe out 6–9 months of savings on smaller BT amounts. |
| Bajaj Finance | 13–14% | NBFC pricing — higher rate band than private banks. Min rate reserved for CIBIL 800+ existing customers with clean repayment. Most new BT applicants get 14–16%. | Up to 3.93% of BT amount (inclusive of GST) — among the highest in the market | Existing Bajaj Finance PL: 4% of principal outstanding + GST across most variants. | BT to Bajaj rarely saves on rate alone — they are not the cheapest. Use case is speed (24–48 hr disbursal) and eligibility flex for thinner profiles. If a bank can take you, the bank will be cheaper. |
| Tata Capital | 10.99–11.99% | CIBIL 750+, salaried with net monthly income above Rs 40k, employer on Tata Capital's approved list. | Up to 2.75% of BT amount + 18% GST | Existing Tata Capital PL: 4.5% of principal outstanding + GST (fixed-rate retail product). | Underrated middle-ground — bank-like rates with NBFC-style turnaround. Good for self-employed professionals (CA / doctor / architect) who get under-quoted by HDFC/ICICI. 2.75% fee is steep — net it against the rate-drop saving carefully. |
Rates shown are illustrative starting ranges for super-prime salaried profiles as of mid-2026. Your actual offer depends on your CIBIL score, employer category, income, FOIR and the lender's current rate card. Processing fees and foreclosure schedules are revised periodically — always verify with the lender before signing the BT loan agreement. TARA AI pulls live offers from 55+ partners so you don't have to chase individual lender websites.

Frequently asked questions
What is personal loan balance transfer?
Personal loan balance transfer is when a new lender takes over the outstanding principal of your existing personal loan and re-issues it at (usually) a lower interest rate, a different tenure, or both. Your old loan is closed out using the new loan's disbursal, and you start fresh EMIs with the new lender. It is essentially a refinance: same debt, new contract, hopefully cheaper. The math only works if the rate gap and remaining tenure are big enough to absorb the foreclosure penalty on the old loan plus the processing fee on the new one.
How much can I save by balance transfer?
It depends entirely on three inputs — outstanding, rate drop, and tenure left. Rough thresholds where savings start to make sense:
- Below Rs 2,00,000: skip — friction (~5.9% of outstanding) almost always exceeds savings.
- Rs 2L – Rs 5L: need at least 4 percentage points rate drop and 30+ months left.
- Rs 5L – Rs 10L: need at least 3 percentage points drop and 36+ months left.
- Above Rs 10L: 2 points (1.5 if processing fee waived) and 36+ months left.
In our worked examples, a Rs 5L outstanding at a 4.5-point drop with 36 months left netted ~Rs 9,758 — marginal. A Rs 3L outstanding at a 5-point drop with 24 months left came in negative after friction. Big rate gaps look exciting in isolation; the saving lives or dies on principal size and runway.
What is the minimum rate difference for balance transfer to be worth it?
There is no single answer — it scales with your outstanding and tenure left. As a working rule: 2 percentage points is the floor for loans above Rs 10 lakh with 3+ years left, 3 points for Rs 5–10 lakh, and 4 points for Rs 2–5 lakh. Anything below 1.5 points almost never clears the ~5.9% all-in friction cost (3% foreclosure + 2% processing + 18% GST on both), regardless of loan size. If you are sitting on a 1.5-point gap, call your existing lender and ask for a rate reduction — it's cheaper than switching.
How long does the break-even take?
Use the quick formula: months_to_break_even = total_friction / monthly_saving. Total friction is roughly 5.9% of your outstanding (3% foreclosure + 2% processing + 18% GST on both). If break-even is more than 50% of your remaining tenure, treat the switch as MARGINAL — the surplus runway is too thin to absorb a bad-luck event like a job change or rate hike. If break-even exceeds your remaining tenure, DON'T SWITCH — you will pay more in fees than you save in EMIs. For most healthy switches, break-even lands between months 18 and 30.
Does balance transfer hurt my CIBIL?
Temporarily, yes — by a few points. The new lender will run a hard enquiry on your CIBIL when you apply, and TransUnion CIBIL does not publish a fixed per-enquiry deduction; industry guidance is that a single hard enquiry causes a low-single-digit dip. Closing the old loan and opening the new one also briefly shortens your average account age. Both effects typically recover within a few months of on-time repayment on the new loan. The real CIBIL risk isn't the BT itself — it's applying to 4–5 lenders simultaneously, which stacks multiple hard enquiries. TARA AI pre-screens eligibility before pulling enquiries so you only apply where you'll get the rate.
Is there a no-foreclosure-penalty personal loan?
Mostly historical, with a recent shift. RBI circular RBI/2013-14/582 dated 7 May 2014 prohibits foreclosure / prepayment charges on floating-rate term loans to individual borrowers. Most Indian personal loans — from HDFC, ICICI, Axis, SBI, Bajaj Finance, Tata Capital, IDFC First, Kotak — are sanctioned on a fixed interest rate basis, which is why a 2–5% foreclosure charge (plus 18% GST) has been standard practice. The RBI Pre-payment Charges on Loans Directions, 2025 (effective 1 January 2026) materially extended the foreclosure-charge prohibition to fixed-rate retail loans for individual non-business borrowers and MSEs — so newer personal loans within scope are now protected. Carve-outs remain (business-purpose loans, certain pre-cutover loans, non-individual borrowers). Always check your loan's KFS for the exact foreclosure schedule that applies to YOUR loan — if you're protected, the balance transfer math becomes materially more favourable.
Should I balance-transfer or prepay?
Prepayment beats balance transfer when your rate gap is below 2 points, your outstanding is under Rs 3 lakh, or your tenure left is under 24 months. Prepayment has zero friction once you're past your lender's initial lock-in window — typically 6 to 12 months from disbursal, with caps on the number of part-prepayments allowed per year. Important: these lock-in rules are lender terms and conditions disclosed in your sanction letter, not an RBI regulation. Read your sanction letter or Key Facts Statement to confirm. Balance transfer wins when the rate gap is wide enough and the tenure long enough that the EMI saving compounds past the fee load. If both are viable, do both: BT first to lock in the lower rate, then part-prepay aggressively after the new lender's lock-in clears.

- Lender published rate cards (HDFC Bank, ICICI Bank, Axis Bank, Bajaj Finance, Tata Capital) — all rate figures in this guide are illustrative starting ranges for super-prime salaried profiles and may not reflect your actual offer. Your rate depends on CIBIL, employer category, income, FOIR and the lender's current rate card. Always verify with the lender before signing.
- TARA AI break-even methodology: All EMI figures use the exact reducing-balance formula EMI = P × r × (1+r)^n / ((1+r)^n − 1). We compare nominal rupee totals over the remaining tenure — NPV-adjusted savings will be 8–15% lower depending on your personal discount rate. We assume the new loan tenure matches the remaining tenure on the old loan; extending tenure on the new loan increases total interest paid even at a lower rate, which is a common silent trap. Friction is modelled at 3% foreclosure + 2% processing + 18% GST on both (effective 5.9% of outstanding). Verdict thresholds: SWITCH if net saving > one month of new EMI; MARGINAL if 0 to one month of new EMI; DON'T SWITCH if below zero. If friction exceeds 50% of total nominal saving, treat as MARGINAL even when net is positive.
