How to use it
- Enter the loan amount, annual interest rate and term in years.
- Click the Calculate button.
- Read the monthly payment, total interest and total of payments results.
Enter the loan amount, annual interest rate and term in years, and the calculator instantly shows three key figures: the monthly payment you’ll need to budget, the total interest you’ll pay over the life of the loan, and the overall amount of all payments combined. Knowing the monthly payment helps you match a loan to your cash flow, while the total interest reveals the true cost of borrowing. The total of payments lets you compare different loan offers side‑by‑side. All results are presented in clear dollar amounts, so you can see at a glance whether a loan fits your financial plan. You can adjust any input and the numbers update instantly, making it easy to test scenarios like a higher rate or a longer term. Use the tool before you sign any paperwork to negotiate better terms or to decide if refinancing makes sense.
Pro tips
- Add a small buffer by rounding the monthly payment up a few dollars to cover fees.
- Use the exact annual rate from your loan offer; APR can differ from the nominal rate.
- Enter the term in whole years; if you need months, convert them to a decimal fraction.
- Make sure the interest rate is entered as a percent, not as a decimal (e.g., 5 not 0.05).

Case study
Emily wanted to buy a $20,000 car but wasn’t sure what she could afford. She entered $20,000, 5% interest and a 5‑year term. The calculator showed a $377 monthly payment, $2,300 total interest and $22,300 total cost, letting her negotiate a lower rate and stay within her budget.
