Early repayment guide and interest-savings calculation
EMI vs equal principal — early repayment behaves very differently
The two methods front-load interest differently, so prepayment saves very different amounts:
- EMI: early payments are interest-heavy (70%+ at the start), so early prepayment saves the most; later on, less
- Equal principal: fixed principal each month with interest on the shrinking balance, so prepayment savings stay fairly stable over time
When is early repayment most worthwhile?
To judge whether prepaying is worth it:
- By stage: prepaying within the first third of the term saves clearly; past the halfway point, savings are limited
- By investment return: if your portfolio reliably beats the loan rate by 1%+, skip prepayment and invest the spare cash instead
- By penalty: some banks charge a 1%–3% penalty within the first 1–3 years — do the full math
- By method: on EMI loans, shortening the term beats lowering the payment
Three Early Repayment Options
- Pay off in full: for those with a windfall (sale, inheritance) who want to be debt-free
- Partial prepayment + same payment: shortens the remaining term and saves the most interest (recommended for EMI)
- Partial prepayment + same term: lowers the monthly payment but saves less interest — for easing near-term pressure
Early Repayment Caveats
- Book ahead: most banks need written or in-app notice 1–30 days ahead; some allow online processing
- Penalty basis: repaid principal is exempt; penalties apply only to the outstanding portion
- Release the mortgage: after full repayment, deregister the mortgage and retrieve your deed promptly
- Keep receipts: print the final settlement certificate and archive it for at least 5 years
- Housing fund last: holding both loans? Prepay the commercial loan first (higher rate)
Savings follow standard contract terms; actual penalties depend on your bank. Investments carry risk — this tool forecasts nothing.
