What is home loan balance transfer?
A balance transfer moves your outstanding home loan from your current lender to a new lender at a lower rate. The new lender pays off the old loan in full (your current lender closes the account) and a fresh loan is opened with the new lender. RBI’s 2014 ban on prepayment penalty for floating-rate home loans makes this a fee-free move from the current-lender side; the new lender charges a fresh processing fee.
How is the net saving computed?
Old EMI = EMI at current_rate on outstanding for remaining tenure
New EMI = EMI at new_rate on outstanding for remaining tenure
Gross interest saving = old_total_interest − new_total_interest
Costs:
New processing fee = outstanding × new_processing_fee_pct
GST on fee = 18% × processing fee
Foreclosure fee = outstanding × foreclosure_fee_pct (0 for floating-rate retail home loan)
GST on foreclosure = 18% × foreclosure fee
Net interest saving = gross saving − all fees and GST
Worked example — ₹40L outstanding, 9.5% → 8.5%, 15 years remaining
| Old loan | New loan | |
|---|---|---|
| Rate | 9.5% | 8.5% |
| EMI | ₹41,769 | ₹39,390 |
| Total interest (15yr) | ₹35.18 lakh | ₹30.90 lakh |
- Gross interest saving: ₹4.28 lakh
- New processing fee (0.5%): ₹20,000 + ₹3,600 GST = ₹23,600
- Foreclosure fee (floating loan): ₹0
- Net interest saving: ~₹4.05 lakh, plus ₹2,379/month lower EMI for 15 years
When transfer is worth it
| Rate gap | Remaining tenure | Verdict |
|---|---|---|
| Below 0.25% | any | Skip — fees eat the saving |
| 0.25%–0.50% | below 5 years | Skip |
| 0.25%–0.50% | above 5 years | Marginal — run the numbers |
| 0.50%–1.00% | above 3 years | Worth it |
| Above 1.00% | above 2 years | Almost always worth it |
Hidden costs to factor in
- New lender’s legal/valuation fee (~₹3,500–₹7,500)
- Document storage / postage (₹500–₹1,500)
- Insurance (some lenders push a fresh life-cover policy — refuse if you already have term coverage)
- Possible delays in disbursement causing 1–2 months of EMI to both lenders during transition
