Reducing-balance EMI calculator for any loan — home, car, or personal — with the full month-by-month amortization schedule so you can see exactly how much of each payment is interest versus principal.
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is principal, r is the monthly interest rate, and n is the number of months. Each month, interest is charged on the outstanding balance, and whatever's left of the fixed EMI reduces principal — which is why the interest portion is largest in month 1 and smallest in the final month, even though the EMI itself never changes.
₹50L at 8.5% for 20 years works out to an EMI of ₹43,391/month. Over the full tenure that's ₹1.04Cr paid — ₹50L principal and ₹54L interest, meaning you pay roughly as much in interest as you borrowed.
Why is so much of my early EMI interest, not principal?▾
Because interest is charged on the outstanding balance, which is highest at the start. As principal reduces month by month, the interest component shrinks and the principal component grows — even though the EMI amount itself is fixed for the whole tenure.
Does a lower EMI always mean a cheaper loan?▾
No — a longer tenure lowers the EMI but increases total interest paid, since you're borrowing the bank's money for longer. Compare total interest paid, not just the monthly figure, when choosing tenure.
