π³ Personal Loan Calculator
Monthly payment, total interest, and the true cost of your unsecured loan.
Monthly Payment

How to Use This Calculator
Enter the loan amount, APR, term, and any origination fee. The calculator shows your monthly payment, the total you repay, the total interest, and a year-by-year payoff summary so you can see how each choice changes the cost.
Enter the Loan Amount you need and the APR from the lender offer. Use the true APR, not a teaser rate.
Pick the Term in years. Longer terms lower the payment but raise total interest, sometimes dramatically.
Enter the Origination Fee percent if the lender charges one. The calculator adds it to the financed balance.
Compare scenarios: try a shorter term or a lower APR to see exactly how many dollars each improvement saves.
The Loan Payment Formula
The formula spreads the loan into equal monthly payments where each payment first covers that month interest on the remaining balance and the rest reduces principal. Because interest is charged on a shrinking balance, early payments are interest-heavy: on a 5-year loan, roughly the first two years payments go mostly to interest.
Worked Example
You borrow $25,000 at 12 percent APR for 4 years with no origination fee. The monthly rate is 0.01 and there are 48 payments: payment = 25000 x 0.01 x 1.01^48 / (1.01^48 - 1) = $658.35. Total repaid = 658.35 x 48 = $31,600.80, so total interest is $6,600.80. Add a 3 percent origination fee ($750 financed, $25,750 total) and the payment rises to $678.10 with $6,798.80 of interest: the fee costs about $948 all in. As a check on the formula, a $100,000 loan at 6 percent over 30 years gives $599.55 a month.
Borrowing Smart With Unsecured Debt
Because there is no collateral, lenders price personal loans for risk, which makes your credit score the biggest lever on the rate. Improving your score before you apply, choosing the shortest affordable term, and refusing loans with prepayment penalties are the three moves that matter. And borrow for appreciating or consolidating purposes, not lifestyle: a loan that replaces 24 percent card debt builds wealth, while a loan for a vacation just moves the bill into the future with interest.

Frequently Asked Questions
How is a personal loan payment calculated?
With the standard amortization formula: payment = P x r x (1+r)^n / ((1+r)^n - 1), where P is the amount financed, r the monthly rate, and n the number of payments. A $25,000 loan at 12 percent APR for 4 years (r = 0.01, n = 48) gives a $658.35 monthly payment. Every payment is part interest on the remaining balance and part principal.
What is a good APR for a personal loan?
It depends on your credit. Excellent-credit borrowers see rates near 8 to 12 percent, average borrowers more like 12 to 20 percent, and weaker credit can exceed 25 percent or push borrowers toward secured options. Because personal loans are unsecured, rates run higher than auto loans or mortgages for the same borrower.
What is an origination fee?
A one-time fee the lender charges for processing the loan, usually 1 to 8 percent of the amount borrowed. Some lenders deduct it from your disbursement, so a $20,000 loan with a 5 percent fee puts only $19,000 in your hands, while others add it to the balance you repay. This calculator adds the fee to the financed amount and shows its cost.
Does a shorter term always save money?
Almost always on interest, but it raises the monthly payment, which is the real constraint. Cutting a $25,000, 12 percent loan from 5 years to 3 years saves about $2,700 in interest but raises the payment from $556.11 to $830.36. Choose the shortest term whose payment still leaves room in your budget for emergencies.
Should I pay off a personal loan early?
Usually yes, if there is no prepayment penalty, because extra payments go straight to principal and cut the interest tail. Check your loan agreement first: some lenders charge a prepayment fee or require a minimum interest period. Also keep an emergency fund intact rather than draining cash to kill the loan a few months sooner.
Personal loan vs credit card: which is cheaper?
The personal loan, almost every time. Credit cards average well above 20 percent APR with minimum payments designed to stretch for decades, while personal loans fix the rate and the payoff date. Consolidating $15,000 of 24 percent card debt into a 12 percent 3-year loan roughly halves the interest and guarantees a finish line.
