What is an EMI / loan calculator?
An EMI (Equated Monthly Installment) calculator works out the fixed monthly amount you'll pay on any loan — personal, auto, education, or mortgage — given the principal, interest rate, and tenure. Each EMI is the same in size, but its composition shifts over time: in the early months most of it covers interest, and only a small slice reduces principal; by the end, almost all of it pays down principal. The calculator also surfaces the total interest you'll pay across the life of the loan and the full amortization schedule, so you can see exactly how much borrowing actually costs.
