What is an EMI?
EMI stands for Equated Monthly Installment, a fixed payment that combines principal and interest, paid every month over the loan tenure. Each payment is the same amount, but early payments are mostly interest while later payments are mostly principal. EMI is the standard format for home loans, car loans, and personal loans worldwide.
How is EMI calculated?
EMI equals P times r times (1 plus r) to the power n, divided by (1 plus r) to the power n minus 1. P is principal, r is monthly interest rate (annual divided by 12 and divided by 100), and n is total months. The calculator handles this automatically and produces the exact monthly figure.
What is an amortization schedule?
It is a table showing every monthly payment broken into principal, interest, and remaining balance. Early payments have a high interest portion that gradually shrinks while principal grows. By the final months, almost all of each payment goes to principal. The calculator displays the full schedule so you can see exactly how the loan unwinds.
How does prepayment affect the loan?
Prepaying lump sums or extra monthly amounts reduces the outstanding principal, which cuts the interest charged on every future payment. You can either reduce the EMI or shorten the tenure; shortening saves more total interest. Even small extra payments early in the loan have an outsized impact because of how amortization front-loads interest.
Should I choose a longer or shorter tenure?
Shorter tenure means higher EMI but much lower total interest. Longer tenure has lower monthly burden but you pay the bank far more over the loan's life. A 20-year home loan can cost twice as much in interest as a 10-year loan for the same principal. Pick the shortest tenure your budget comfortably allows.
Is the EMI the same as the loan repayment?
No. EMI is one monthly installment. Total repayment is EMI multiplied by the number of months, which equals principal plus all interest. On a long loan, total repayment can be 1.5 to 2 times the original principal. The calculator shows both figures so you can see the true cost of borrowing.
