How to use this page
Home Loan Amortization and Extra-Payment Calculator is best used as a structured decision tool. Enter or compare like-for-like inputs, make the assumptions explicit and test a downside case before relying on the output.
Practical checklist
- Use inputs from dated statements, contracts or operating records instead of rough estimates where possible.
- Keep units and periods consistent (monthly vs annual, pre-tax vs post-tax, nominal vs real).
- Run at least one conservative scenario and identify the assumption that drives the result most.
- Use the result as screening evidence and document any professional or legal adjustment separately.
Worked use case
Example: if one assumption changes the answer materially, show that variable as a range instead of presenting a single-point result as certain.

How This Is Calculated
This calculator computes your EMI using the standard loan amortization formula, then simulates the loan schedule month by month — each EMI first covers the interest accrued on the outstanding balance, with the remainder reducing principal. Adding extra/prepayment amounts reduces the outstanding principal faster, cutting the total interest paid and/or shortening the loan tenure, depending on which strategy you choose.
Frequently Asked Questions
Why does most of my early EMI go toward interest, not principal?
▼
In the early years of a loan, the outstanding balance is highest, so the interest portion of each EMI (interest = outstanding balance × monthly rate) is largest. As the balance reduces over time, a growing share of each EMI goes toward principal instead — this is standard amortization behavior, not something specific to any one lender.
Does prepaying my home loan reduce EMI or tenure?
▼
It depends on what you choose with your lender. Reducing tenure (keeping EMI the same, paying off faster) saves more total interest than reducing EMI (keeping tenure the same, lowering the monthly payment) for the same prepayment amount, because the loan is outstanding for a shorter total period.
Is there a penalty for prepaying a home loan?
▼
For floating-rate home loans to individual borrowers, RBI rules generally prohibit prepayment penalties. Fixed-rate loans may still carry prepayment charges — check your specific loan agreement.

This amortisation tool models contractual cash flows from user inputs; it is not a lender statement. Floating-rate resets, day-count conventions, fees, insurance, part-payment rules and lender-specific re-amortisation can change actual results. This batch must not alter the existing JavaScript or control IDs.
Practical verification checklist
- Match annual/monthly rate convention to loan terms.
- Test prepayment timing and lender charges separately.
- Reconcile final schedule to lender statement before financial decisions.
