Calculate personal loan monthly payments, APR, and total costs including fees and insurance.
Before you sign for a personal loan, you should know the full cost, not just the monthly payment a lender highlights. A personal loan calculator takes your loan amount, interest rate, and term, then shows your monthly payment alongside the total interest you'll pay over the life of the loan. That second number is where surprises hide. With personal loan rates averaging about 12.28% in mid-2026 for borrowers with good credit, and ranging from roughly 6% to nearly 36% depending on your profile, the difference between a good and mediocre rate is enormous. This personal loan calculator helps you compare offers honestly, factor in origination fees, and decide whether borrowing makes sense for your situation.
This personal loan calculator shows the true cost of borrowing a fixed sum and repaying it in equal monthly installments. You enter the loan amount, the interest rate, and the repayment term, and it returns your monthly payment, total interest, and total repayment amount. Because many personal loans carry an origination fee, the tool lets you include it so you see your real APR rather than just the advertised rate. It's designed for US borrowers comparing unsecured loans for debt consolidation, home improvements, medical bills, or major purchases. Unlike revolving credit, a personal loan has a fixed end date, and the calculator makes that finish line and its cost crystal clear before you commit.
Enter the loan amount you want to borrow.
Input the annual interest rate (APR) the lender quoted you.
Choose your repayment term, typically two to seven years.
Add any origination fee, often 1% to 8%, to see your true cost.
Click calculate to view your monthly payment, total interest, and total repayment.
Adjust the term or rate to compare loan offers side by side.
The calculator relies on the standard fixed-rate amortization formula. It converts your annual rate to a monthly rate by dividing by 12, then computes the level monthly payment that fully repays the loan over the term: payment = principal × r ÷ (1 − (1 + r)^−n), where r is the monthly rate and n is the number of payments. Each month, part of your payment covers interest on the current balance and the rest reduces principal, with the principal share growing as the balance falls. If you add an origination fee, the calculator either adds it to the amount financed or subtracts it from your disbursed funds, then recomputes the effective APR so you see the loan's real cost, not just the sticker rate.
The rate you're offered isn't arbitrary; it's a direct read on how lenders see your risk. Your credit score is the heaviest factor: in 2026, borrowers with excellent credit see rates near 14.5%, good credit around 19%, and fair credit above 22%. Beyond your score, lenders weigh your debt-to-income ratio, income stability, and loan term, since longer terms sometimes carry higher rates. Where you apply matters too: credit unions averaged about 10.72% in 2026, well below many banks and online lenders. The practical move is to prequalify with several lenders using soft credit checks, which lets you compare real rates without harming your score. The rate you enter here should reflect an offer you can genuinely get.
Here's a cost that quietly inflates many personal loans: the origination fee. Lenders often charge 1% to 8% of the loan amount upfront, and they typically deduct it from the money you actually receive. Borrow $10,000 with a 5% fee and you walk away with $9,500, yet you still repay the full $10,000 plus interest. That gap means your true APR is higher than the advertised rate, sometimes noticeably so. A loan with a lower headline rate but a steep fee can cost more than one with a slightly higher rate and no fee. Always compare offers using APR, which folds the fee in, rather than the interest rate alone. The calculator's fee field exists precisely so you don't fall for the sticker number.
Choosing between a personal loan and a credit card comes down to structure and rate. A personal loan gives you a fixed rate, a fixed payment, and a definite payoff date, which makes it ideal for a known, one-time expense or for consolidating high-rate card debt. With cards averaging around 24% in 2026 and personal loans often far lower, moving balances can save real money, as long as you don't keep charging. Credit cards, by contrast, suit small, recurring, or short-term spending you'll repay quickly, especially if you earn rewards and pay in full. The trap is using a personal loan to fund a lifestyle rather than solve a specific problem. Match the tool to the need: fixed expense, fixed loan; flexible spending, the card.
Elena borrows $10,000 at 12.28% over 3 years with no origination fee. Her monthly payment is about $334, and she pays roughly $2,020 in total interest, for a total repayment near $12,020. If she stretches the same loan to 5 years, her payment drops to about $224, but total interest climbs to roughly $3,440, so the longer term costs her an extra $1,420.
Raj takes a $15,000 loan at 18% over 4 years with a 5% origination fee ($750). The fee is deducted, so he receives $14,250 but repays based on $15,000. His monthly payment is about $441, total interest is roughly $6,160, and once the fee is folded in, his effective APR rises to around 20.4%, well above the quoted 18%.
Compare loans by APR, not the interest rate, so origination fees are included in your comparison.
Prequalify with several lenders, including credit unions, using soft credit checks to find your lowest rate.
Choose the shortest term your budget can handle, since longer terms quietly multiply total interest.
Borrow only what you need; a bigger loan means more interest even at the same rate.
Check for prepayment penalties before signing, so you can pay the loan off early without a fee.
Use a personal loan for a specific purpose with a clear payoff, not for ongoing everyday spending.
A personal loan calculator estimates your monthly payment, total interest, and total repayment from your loan amount, rate, and term. It can also include origination fees to reveal your true APR.
The average personal loan rate is about 12.28% in mid-2026 for a borrower with good credit, though rates range from roughly 6% to nearly 36% depending on credit and lender. Credit unions tend to offer the lowest rates.
Payments use a fixed-rate amortization formula that divides your principal plus interest into equal monthly amounts over the term. Each payment covers interest first, then reduces principal, with the principal share rising over time.
Yes, significantly. An origination fee of 1% to 8% is usually deducted from your funds, so you receive less but repay the full amount. This raises your effective APR above the advertised rate.
A personal loan is usually better for a fixed, one-time expense or consolidating high-rate card debt, thanks to its fixed payment and payoff date. Credit cards suit small, short-term spending you'll repay quickly.
Most personal loans allow early payoff, which saves interest, but some charge a prepayment penalty. Check your loan agreement before signing, and use any windfall to clear the balance faster if no penalty applies.
