See what a loan really costs
A loan's monthly payment is only part of the picture; the total interest over the full term is what tells you how much the borrowing actually costs. This calculator takes the amount, interest rate, and term and works out the monthly payment, the total you'll repay, and the interest on top — so you can compare offers on the numbers that matter, not just the headline rate.
How to use it
- Enter the loan amount, annual interest rate, and term.
- Read the monthly payment.
- Check the total repaid and total interest.
What to compare
- A longer term lowers the monthly payment but usually raises total interest.
- Even a small rate difference adds up over a long term.
- Total cost, not just the monthly figure, shows the true price.
Questions people ask
Does this include fees? It covers principal and interest. Arrangement fees and insurance are extra, so add those when comparing real offers.
