What the calculator does
It takes three inputs—loan amount, annual interest rate, and term in years—and instantly shows three key figures: the monthly payment you’ll owe, the total interest you’ll pay over the life of the loan, and the grand total of all payments.
Why it matters
Knowing your monthly payment helps you budget correctly, while the total interest reveals the true cost of borrowing. Seeing the overall payment amount lets you compare loan offers side‑by‑side.
How to read the results
- Monthly payment – the amount deducted each month.
- Total interest – the extra money paid beyond the principal.
- Total of payments – sum of all monthly payments, equal to principal + interest.
Use the numbers to test different rates or terms, and see how a few extra points of interest can swing your payment by hundreds of dollars.
Pro tips
- Add a small buffer (5‑10%) to your budget for payment fluctuations.
- Round the loan amount to the nearest hundred for quicker mental checks.
- Enter the rate as a whole number (e.g., 5 for 5%).
- Double‑check the term years; a 30‑year mortgage vs 15‑year changes payment dramatically.

Case study
