EMI Calculator Guide: Understand Loan Payments

An EMI combines principal and interest into a recurring payment, but affordability requires looking beyond the monthly number.

The reducing-balance formula

QuickCalcy converts the annual rate to a monthly rate and applies the standard loan-payment equation across all monthly instalments. A zero-rate loan is divided evenly across the selected months.

Rate and tenure trade-off

A longer tenure usually lowers EMI but raises total interest because principal remains outstanding longer. Compare monthly EMI, total repayment and total interest together.

Compare offers consistently

Use the same principal and tenure, then add processing, legal, insurance and other charges separately. Check whether the rate is floating, how resets work and whether prepayment has conditions.

Mistakes and limitations

The estimate excludes fees, daily-interest conventions, payment holidays and lender rounding.
