The cost of borrowing

APR is treated as a simple annual rate compounded monthly. Lenders quote APR in a standardised way that can include fees, so the headline figure may differ slightly.

Common questions

How does the loan calculator work?

Enter the amount, the interest rate (APR) and the term, and it shows your monthly repayment and the total interest using the standard amortising-loan formula.

What is APR and why does it matter?

APR is the yearly cost of a loan including interest and most fees. Comparing loans by APR, rather than by the monthly payment alone, shows which is genuinely cheaper.

Does a longer term cost more?

Yes. Spreading a loan over more years lowers each payment but increases the total interest, because you owe the balance for longer.
