FAQ
What is EMI and how is it calculated?
EMI stands for Equated Monthly Installment - the fixed amount you pay each month on a loan. It is calculated using the standard reducing-balance formula: EMI = P * r * (1+r)^n / ((1+r)^n - 1), where P is the principal, r is the monthly interest rate (annual rate divided by 12), and n is the number of months. The same EMI is paid every month, but the principal/interest mix shifts over time.
Does the calculator support zero-interest loans?
Yes. If you set the annual interest rate to 0, the EMI is simply the principal divided by the number of months, and no interest rows appear in the amortization schedule. This makes the tool useful for both interest-free and standard loans.
Why does the interest share shrink as the loan progresses?
With a reducing-balance EMI, each payment first covers the interest accrued on the remaining balance that month, and the rest goes to principal. As the balance drops, the interest portion of every EMI falls, so more of each payment goes to principal. The full schedule shows this shift month by month.
Can I use this for mortgages, car loans, or personal loans?
Yes. The math is identical for any fixed-rate installment loan - home loans, car loans, personal loans, education loans, and similar products. Just plug in the principal, the rate you were offered, and the tenure in months or years, and the calculator returns the EMI and a full schedule.
Is my loan data sent anywhere?
No. All calculations are performed entirely in your browser using client-side JavaScript. Your principal, rate, tenure, and currency selection never leave your device, so you can experiment with numbers without sharing your finances.
