How to use it
- Enter loan amount.
- Enter annual interest rate.
- Enter loan term in years.
- Read monthly payment, total interest, and total of payments.
What it does The calculator takes the loan amount, interest rate, and term to show three key figures: the monthly payment you’ll owe, the total interest you’ll pay over the life of the loan, and the sum of all payments. Why it matters Knowing these numbers lets you compare offers, budget cash flow, and avoid surprises when the loan ends. How to read it
- Monthly payment is the amount due each month. - Total interest is the extra cost of borrowing. - Total of payments is the combined amount of principal plus interest. Use these figures to decide if a loan fits your financial plan.
Pro tips
- Round the loan amount to the nearest hundred for quicker comparisons.
- Include taxes, fees, and insurance in your budget, not just the loan payment.
- Check the APR, not just the nominal rate, for true cost.
- Recalculate if you change the loan term or make extra payments.

Case study
Jenna wanted to know if a 5‑year loan at 4.2% would fit her budget. She entered $22,000, 4.2, and 5 into the calculator and saw a $406 monthly payment, $4,360 total interest, and $26,360 overall cost. Armed with those numbers, she negotiated a lower rate and saved over $500 in interest.
