Loan EMI Calculator
Calculate your monthly loan EMI (Equated Monthly Installment), total interest, and full payment breakdown for any loan. Includes a guide on how amortization works, how tenure affects total cost, and how to compare loan offers.
Loan Breakdown
How to Use This Tool
- Enter the loan amount you plan to borrow.
- Enter the annual interest rate offered by the lender.
- Enter the loan tenure in years.
- Read the Monthly EMI — the fixed amount you'll pay each month.
- Check Total Interest and Total Payment to see the full cost of the loan over its life.
- Compare the principal-vs-interest bar to see how much of your total payment goes to interest versus paying down the loan.
Formula & How It Works
EMI Formula
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1)P is the loan principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the total number of monthly payments (years × 12). This reducing-balance formula produces a fixed monthly payment for the life of the loan.
Total Payment & Total Interest
Total Payment = EMI × n; Total Interest = Total Payment − PMultiplying the fixed EMI by the number of payments gives the total amount paid; subtracting the original principal gives the total interest cost.
Practical Examples & Common Use Cases
Example 1: $25,000 car loan at 7.5% for 5 years
Monthly rate = 7.5% ÷ 12 = 0.625%. n = 60 months. EMI = $25,000 × 0.00625 × (1.00625)^60 ÷ ((1.00625)^60 − 1) ≈ $500.46/month. Total payment ≈ $30,028; total interest ≈ $5,028.
Example 2: Same loan stretched to 7 years
With n = 84 months at the same 0.625% monthly rate, the EMI drops to about $382/month, but total interest rises to about $7,090 — $2,062 more than the 5-year term, because interest accrues over a longer period.
Example 3: $10,000 personal loan at 10% for 3 years
Monthly rate = 10% ÷ 12 ≈ 0.833%. n = 36 months. EMI ≈ $322.67/month. Total payment ≈ $11,616; total interest ≈ $1,616, about 16.2% of the original loan amount.
Frequently Asked Questions
EMI stands for Equated Monthly Installment — the fixed amount you pay each month to repay a loan. Each EMI payment covers the interest charged for that month plus a portion of the principal balance.
Yes, significantly. A shorter tenure means higher monthly payments but dramatically less total interest. On a $25,000 loan at 7.5%, a 3-year term saves about $2,000 in interest compared to a 5-year term, even though the monthly payment is $277 higher. The right trade-off depends on your monthly cash flow.
A flat rate interest loan charges interest on the original principal throughout the tenure. A reducing balance loan charges interest only on the remaining principal each month. Reducing balance (which this calculator uses) is the standard for most personal and auto loans and results in lower total interest.
You can typically reduce your EMI by making a part-prepayment, which reduces the outstanding principal. After the prepayment, your lender will recalculate either a lower EMI for the same tenure or the same EMI for a shorter tenure. Check your loan agreement for prepayment terms and any penalties.
The interest rate is the cost of borrowing the principal. APR (Annual Percentage Rate) includes the interest rate plus any fees, such as origination fees, processing fees, or mortgage points. APR gives a more complete picture of the true cost of a loan. Always compare APRs — not just interest rates — when shopping lenders.
No. This calculator computes EMI based on principal, interest rate, and tenure only. Real loans may also have origination fees (typically 1–5%), insurance, and other charges that add to the total cost. Add these to your comparison when evaluating actual loan offers.
