Loan / EMI Calculator

Methodology, interpretation & sources

Purpose. Calculates the monthly installment (EMI), total interest, and total repayment for any fixed-rate loan using the standard amortization formula.

Method overview. For a standard reducing-balance loan with equal periodic payments, EMI is based on principal, the periodic interest rate and total number of payments. A common form is P × r × (1+r)^n ÷ ((1+r)^n − 1).

Worked example. A Rs. 1,000,000 loan at 12% nominal annual interest over five years, paid monthly, uses a monthly rate of 1% and 60 payments. The calculator converts those assumptions into an estimated monthly instalment and total interest.

Interpretation. Actual lender schedules may differ because of fees, insurance, taxes, rate resets, day-count conventions, grace periods or early-settlement rules. Compare the lender's disclosed APR/effective rate and amortization schedule before committing.

How to use the result. Start with source data you can verify, enter values on a consistent unit and time basis, and record the assumptions used. The main inputs on this page include Loan Amount (Principal), Annual Interest Rate (%), Loan Tenure (Years), Your Name, Email, Company Name. Re-run the calculation when those assumptions change rather than carrying an old result forward.

Decision use. Use this tool for scenario planning and comparison rather than as a substitute for professional financial advice. Financial assumptions can change the result materially, so test more than one scenario instead of relying on a single output.

Limitations. Check the time period, rate convention, compounding assumption and cash-flow timing before interpreting the result. Small changes in rates or timing can have a large cumulative effect.
