Loan Calculator — Personal & Auto Loan Payment Estimator
Free loan calculator for personal loans, auto loans, and other installment loans. Calculate your monthly payment, total interest, and total cost.
A loan calculator takes the guesswork out of borrowing money. Whether you are considering a personal loan to consolidate debt, an auto loan for a new car, or any other installment loan, knowing your real monthly payment and total cost before you sign is the difference between a smart financial decision and a regret-filled one.
Our loan calculator uses the same standard amortization formula that banks and credit unions use, giving you instant, accurate numbers. Enter the loan amount, interest rate, and term, and you will see the monthly payment, total interest paid, and total cost of the loan. Try different scenarios to find the term that best balances affordability with total cost.
How a loan payment is calculated
Loan payments use the amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where M is the monthly payment, P is the loan principal, r is the monthly interest rate, and n is the total number of monthly payments. This formula ensures equal monthly payments throughout the loan, even though the split between interest and principal changes each month.
In the early payments, most of your money goes toward interest. As the loan balance shrinks, more of each payment chips away at the principal. By the end of the loan, almost all of each payment is going to principal. This is called amortization, and it is why paying extra early in a loan saves so much more interest than paying extra at the end.
Personal loans vs auto loans vs credit cards
Personal loans are unsecured installment loans, typically 1-7 years with rates from 6% to 36% depending on credit. They are popular for debt consolidation, home improvements, and major purchases. Because they are unsecured (no collateral), rates are higher than secured loans.
Auto loans are secured by the vehicle, which means lower rates — typically 4% to 10% for borrowers with good credit. Terms run 36 to 84 months, but longer terms mean dramatically more interest. A $25,000 car at 6% over 60 months costs $483/month and $3,991 in interest. The same loan over 84 months drops the payment to $365 but raises total interest to $5,659 — and you may end up owing more than the car is worth.
Credit cards are revolving credit with much higher rates (typically 18%-25%+) and minimum payments that can keep you in debt for decades. Always pay credit cards in full each month if possible. If you carry a balance, a personal loan to consolidate at a lower rate often saves substantial interest.
Tips to get a better loan rate
Check your credit score before applying. Lenders price loans heavily based on credit, and a 50-point improvement can save you thousands. Review your credit report for errors, pay down credit card balances, and avoid new credit applications in the months before applying.
Shop multiple lenders within a 14-day window. Credit scoring models treat multiple loan inquiries within 14 days as a single inquiry, so you can compare rates without damaging your credit. Get quotes from your bank, credit unions, and online lenders.
Choose the shortest term you can comfortably afford. A shorter loan has higher monthly payments but dramatically less total interest. A 36-month auto loan instead of 60 months can save thousands in interest, even though the monthly payment is higher.
How to use this calculator
- Enter the loan amount you want to borrow.
- Enter the annual interest rate offered by the lender.
- Enter the loan term in months or years.
- Click Calculate to see your monthly payment and total cost.
- Try different rates and terms to find the best fit for your budget.
Worked example: $20,000 personal loan at 9% for 5 years
Monthly payment: $20,000 × [0.0075(1.0075)^60] / [(1.0075)^60 − 1] ≈ $415.17 per month.
Total paid over 60 months: $415.17 × 60 = $24,910. Total interest: $4,910 — about 25% on top of what you borrowed.
If you stretched the same loan to 7 years, the monthly payment would drop to $321 but total interest would jump to $6,964 — over $2,000 more for the same loan.
Frequently asked questions
What is a good interest rate on a personal loan?
Excellent credit (740+) typically gets 6%-10%. Good credit (670-739) gets 10%-18%. Fair credit (580-669) gets 18%-30%. Poor credit may face 30%+ or denials.
Should I pay off my loan early?
Yes if there are no prepayment penalties. Paying extra principal saves interest and shortens the loan. Check your loan agreement for any prepayment fees first.
What is the difference between secured and unsecured loans?
Secured loans (mortgages, auto loans) are backed by collateral — the lender can take the asset if you default. This lowers their risk and your interest rate. Unsecured loans (personal loans, credit cards) have no collateral and higher rates.
How does the loan term affect total cost?
Longer terms mean lower monthly payments but much higher total interest. Always check the total cost, not just the monthly payment.
