An EMI (Equated Monthly Installment) is the fixed amount you pay each month to repay a personal loan — part principal, part interest. The calculator above computes this instantly for USD, GBP, AUD, INR, and more. Below is exactly how EMI is calculated, with a full worked example, so you can verify the math yourself.
$$E = P \cdot r \cdot \frac{(1+r)^n}{(1+r)^n – 1}$$
Say you’re borrowing $10,000 at 12% annual interest over 3 years.
This is exactly what the calculator above does automatically — enter your principal, rate, and tenure, and it returns the EMI, total interest, and total repayment instantly.
Every EMI payment has two parts:
Early in the loan, more of each payment goes to interest. As the balance shrinks, more goes to principal — this is why paying extra early saves more than paying extra later.
Because n is an exponent in the formula, tenure has an outsized effect on total interest paid — not just the monthly payment.
Paying $110 more per month over the shorter term saves nearly $1,400 in interest — the calculator’s “Total Interest” field makes this trade-off visible before you sign anything.
Rates depend heavily on FICO score — above 740 can mean 6-8% APR; “fair” credit can mean 25%+. Most US personal loans have no prepayment penalty.
UK lenders often use tiered APRs, where borrowing more can mean a *lower* rate. Try a few different loan amounts in the calculator to check this before committing.
Secured personal loans (backed by a vehicle, for example) typically get a lower rate than unsecured ones — worth comparing both in the calculator.
Typical rates run 10.5%–20% APR. The EMI formula and logic are identical; only the currency and typical rate range differ.
Use E = P × r × (1+r)^n ÷ [(1+r)^n − 1], where r is your monthly rate (annual rate ÷ 12) and n is the tenure in months. See the worked example above for the full calculation with real numbers.
EMI is calculated from three inputs — principal, monthly interest rate, and tenure in months — using the formula above. It stays fixed for the life of the loan, but the split between interest and principal shifts each month.
It depends on rate and tenure. At 12% APR over 3 years, the EMI is about $332/month. Enter your own numbers into the calculator above for an exact figure.
No — the opposite. A longer tenure lowers your monthly EMI but increases total interest paid, often substantially, because interest compounds over more months.
