About Credit calculators
Credit calculators show the true cost of borrowing before you commit. Estimate a monthly loan payment, reveal the effective APR behind an advertised rate, check how much you can safely borrow, and see whether refinancing or early repayment saves money.
Frequently asked questions
How is a monthly loan payment calculated?
The monthly payment depends on the amount borrowed, the interest rate and the term; it is fixed so that equal instalments repay both interest and principal by the end. The calculator returns the instalment and the total cost.
How is APR different from the interest rate?
The interest rate is the price of the money alone, while the effective APR also folds in fees, mandatory insurance and payment timing — so the APR is the number to compare offers by.
How much can I borrow?
Lenders cap your combined monthly loan payments at a share of your net income (the debt-to-income limit). An affordability calculator estimates the loan amount that fits within that limit.
Does early repayment save money?
Paying off a loan early cuts the interest on the remaining balance, so it usually saves money — but check for any early-repayment fee. The calculator compares the two scenarios.
Should I refinance my loan?
Refinancing is worth it when the new rate and fees leave you paying less overall than staying with the current loan; the refinancing calculator compares total costs so you can decide.
