Why prepayment can help
In reducing-balance loans, interest is charged on outstanding principal. Paying principal early can reduce future interest, especially in the early years of a long loan.
Check lender rules
Some lenders have lock-in periods, part-payment minimums, foreclosure fees, or different rules for fixed and floating rates. Confirm the policy before making a large payment.
Limitations
This is an estimate. It assumes the rate and EMI remain constant and does not model exact payment dates, reset dates, penalties, tax effects, or fees.

It does not include lender-specific fees, tax classification, market volatility, eligibility rules, or provider quotations unless you enter those values yourself.

FAQs
Is prepayment always best?
Not always. Compare interest saved with liquidity needs, emergency funds, investment alternatives, and lender charges.
Does this reduce EMI or tenure?
This page estimates tenure reduction when EMI stays the same.
Can I use it for home loans?
Yes, as a planning estimate if the loan uses reducing-balance EMI.
Does it include prepayment penalties?
No. Add lender charges separately.
Why are early prepayments powerful?
More outstanding principal remains early in the loan, so principal reduction can affect more future interest.
Is the future payment saved exact?
No. It is a simplified estimate based on fixed-rate math.
