Loan & EMI Calculator

EMI stands for Equated Monthly Installment — the fixed amount you pay each month to repay a loan over a set period. Each EMI has two components: principal (reduces your outstanding balance) and interest (cost of borrowing). Early payments are mostly interest; later payments are mostly principal.

EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P = principal loan amount, r = monthly interest rate (annual rate ÷ 12 ÷ 100), and n = number of monthly payments. For example, a $10,000 loan at 8% annual interest over 3 years: r = 0.08/12 = 0.00667, n = 36. EMI = 10000 × 0.00667 × (1.00667)^36 ÷ ((1.00667)^36 − 1) = $313.36.

Flat rate interest is calculated on the original principal throughout the loan term. Reducing balance (which this calculator uses) charges interest only on the outstanding principal — so interest decreases each month as you repay. Reducing balance is the standard method for most US, UK, and Indian bank loans. A flat rate of 5% is roughly equivalent to a reducing balance rate of ~9-10%.

A shorter term means a higher monthly EMI but significantly less total interest paid. For example, a $20,000 loan at 7% over 5 years: EMI = $396, total interest = $3,761. The same loan over 3 years: EMI = $618, total interest = $2,232 — saving $1,529 in interest. Use the term slider to find your preferred balance between monthly affordability and total cost.

An amortization schedule is a table showing every monthly payment broken down into its principal and interest components. It also shows the remaining balance after each payment. This is useful for understanding how quickly you build equity (for a home loan) and planning prepayments strategically.

It depends on your lender's policy. Most lenders apply prepayments to reduce the outstanding principal, which shortens the loan term while keeping the EMI the same. Some lenders allow you to reduce the EMI instead. Paying even one extra EMI per year can reduce a 30-year mortgage by several years and save tens of thousands in interest.

A common rule of thumb: total monthly debt payments (including the new loan) should not exceed 36–43% of your gross monthly income (the debt-to-income ratio). For a home loan, lenders typically allow up to 28% of gross income for housing costs. Use our Debt-to-Income calculator to check your eligibility before applying.
