How personal loan repayments work
A personal loan spreads the amount you borrow plus interest into equal monthly payments over a fixed term. The calculator uses the standard amortisation formula: it converts the representative APR to a monthly rate, then works out the payment that clears the balance by the end of the term.
The representative APR is the rate lenders must offer to at least 51 percent of accepted applicants. Your personal rate may differ. Read our personal loans UK guide for how loans work, or see our guide to minimum credit card payments if you are comparing loan costs with revolving credit, or use the debt repayment calculator to plan paying down several balances.
Choosing a loan term
A longer term lowers the monthly payment but usually increases total interest. A shorter term costs more each month but less overall. Before you borrow, check whether an emergency fund could cover the expense without taking on debt, and compare options on the personal finance hub.
Frequently Asked Questions
The payment is found with the standard amortisation formula, which spreads the amount borrowed plus interest evenly across the term. It uses the loan amount, the monthly interest rate (the APR divided by 12), and the number of months, so each payment covers some interest and some of the balance.
APR, the annual percentage rate, shows the yearly cost of borrowing including interest and any compulsory fees. It lets you compare loans on a like-for-like basis. The advertised figure is the representative APR, which lenders must offer to at least 51 percent of accepted applicants.
The interest rate is the cost of the money you borrow. APR includes that interest plus certain compulsory charges, so it is usually a little higher and gives a fuller picture of the cost. Comparing APRs is the fairer way to compare loans.
Not always. Lenders only have to offer the advertised representative APR to at least 51 percent of accepted customers, so your personal rate could be higher depending on your credit history and the amount and term you choose.
Usually yes. A longer term lowers the monthly payment but you pay interest for longer, so the total interest is normally higher. A shorter term costs more each month but less overall. The calculator shows both figures so you can compare.
Most personal loans allow early repayment, but lenders can charge up to one to two months of interest as an early settlement fee on regulated agreements. Check the agreement, as repaying early can still save money overall by cutting future interest.
An unsecured personal loan is not tied to an asset. A secured loan is backed by something you own, often your home, which can mean a larger amount or lower rate, but the asset is at risk if you do not keep up payments.
A full application leaves a hard search on your credit file, which can dip your score slightly. Many lenders offer an eligibility or quotation check using a soft search, which does not affect your score, so you can see likely rates before you formally apply.
