Early payments are mostly interest; later ones mostly clear the balance. A shorter term raises the monthly payment but cuts the total interest sharply. Many lenders let you overpay or settle early — check for early repayment charges first. Not sure what the rate really means? Read what is APR? Buying a car?

Frequently asked questions
How are loan repayments calculated?
A personal loan is amortising: a fixed monthly payment is set so the balance reaches zero by the end of the term. Each payment covers the month’s interest on the remaining balance first, with the rest reducing what you owe — so early payments are mostly interest and later ones mostly principal.
What is APR and is it the same as the interest rate?
APR (Annual Percentage Rate) bundles the interest rate together with any compulsory fees into a single yearly figure, so it’s the fairest way to compare loans. The “representative APR” is what at least 51% of accepted applicants get — the rate you’re actually offered can be higher.
Does a longer term make a loan cheaper?
A longer term lowers the monthly payment but increases the total interest you pay, because you owe the money for longer. A shorter term costs more each month but far less overall. Use the year-by-year breakdown to see the trade-off.
Can I pay a loan off early?
Usually yes. Under UK rules you can settle a regulated loan early and only pay interest up to roughly 28–58 days after you tell the lender, though some agreements add an early repayment charge. Overpaying reduces the balance and the total interest — always check your agreement first.
Will using this calculator affect my credit score?
No. This is just a maths tool — nothing is sent to a lender and there is no credit check. A real application involves a credit search, but many lenders offer a soft-search “eligibility check” that shows your likely rate without affecting your score.

The representative APR is a guide — the rate you are offered depends on your circumstances and credit history, and your actual agreement may include fees.
