How the EMI calculator works
Equated Monthly Installment (EMI) is the fixed amount you pay each month toward a loan. This tool splits that payment into principal and interest using the standard reducing-balance formula. All math runs in your browser. Nothing is sent to a server.
Enter the loan amount, annual interest rate, and tenure. Results update as you type, including monthly EMI, total interest, total payment, and an optional amortization schedule. If your home loan has a long fixed period before annual rate resets, the 10/1 ARM mortgage calculator models that adjustable-rate path. Before you commit to a payment, the 28/36 rule calculator checks whether that EMI fits common front-end and back-end DTI limits.
EMI formula
P is the principal, r is the monthly interest rate, and n is the number of months. If the interest rate is zero, EMI is principal divided by months:
If you need a weekly, biweekly, or quarterly installment, or you want to solve for the rate or term instead of the payment, the advanced loan calculator uses the same amortizing formula with separate compounding and payment frequencies.
