Why Early Prepayment Wins | Reduce Tenure vs EMI | Lump Sum vs Frequent Payments | When to Refinance | Worked Examples | Execution Checklist | FAQs
Why Early Prepayment Saves More
Interest accrues on outstanding principal. Early extra payments shrink the base for remaining months, compounding savings.
Reduce Tenure vs Reduce EMI
Reduce tenure: keeps EMI roughly same, maximizes interest saved.
Reduce EMI: lowers monthly outgo, saves less interest.
Lump Sum vs Frequent Part-Payments
Frequent early part-payments usually beat waiting for a big lump sum if prepayment terms same. Maintain emergency buffer though.
Refinancing (Balance Transfer) Rules & ROI
You switch lenders for a lower rate. Savings must exceed switching costs (0.5–1% processing + ₹20–40K legal/valuation).
Outstanding ₹25L, remaining 15yr tenure, current rate 10.25%, new rate 9.25%, switching cost ₹20K. EMI drop ₹1,300, interest saved >₹3L. Breakeven 15 months.

Worked Examples
Case A: Home loan prepayment
Loan ₹30L 9.5% 20yr EMI ₹28K. Prepay ₹2L at month 12 reduce tenure -> interest saved ₹3.8–4.5L.
Case B: Annual 5% prepayments
Loan ₹20L 10% 20yr. Prepay 5% opening principal annually first 5 years -> interest saving ₹2–3L over no prepayment.
Case C: Refinancing
Outstanding ₹25L 15yr remaining at 10.25%. New 9.25% with ₹20K cost -> net savings ₹3.1L.
Execution Checklist
- Confirm prepayment rules/min amounts with lender
- Request updated amortization schedule after each prepayment
- Keep proof of prepayment instructions and confirmations
- Evaluate refinancing annually; calculate NPV of savings vs costs
- Maintain 3–6 months expense buffer before aggressive prepayment
- Use our calculator to model both reduce-tenure and reduce-EMI options
FAQs
What if lender charges part-prepayment fees?
In fixed-rate products, fees are common; quantify them and compare with projected interest savings. Many floating home loans to individuals disallow prepayment fees per RBI.
Is refinancing always worth it?
No. Calculate net NPV of savings vs switching costs. Late in tenure, savings shrink.
How much emergency buffer should I keep?
3–6 months of expenses/EMIs before aggressive prepayment; maintain liquid savings.
