How to use it
- Enter the loan amount, interest rate, and term in years.
- Click Calculate.
- Read the monthly payment, total interest, and total of payments.
What it does – The Loan Cost Calculator takes your loan amount, annual 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 combined total of all payments.
Why it matters – Knowing the monthly payment helps you fit the loan into your cash flow, while the total interest reveals the true cost of borrowing. The total of payments lets you compare different offers side‑by‑side.
How to read the results – The Monthly payment is the amount due each month. Total interest is the extra money paid beyond the principal. Total of payments equals principal plus interest, giving you the final amount you’ll have paid. Use the calculator whenever you’re shopping for a new loan, refinancing an existing one, or simply checking the impact of a rate change.
Pro tips
- Round the interest rate to two decimals for more accurate results.
- Include any fees or extra charges in the loan amount for a true cost picture.
- Compare the monthly payment against your budget before committing.
- Remember the total of payments includes principal plus interest, not just the interest.
