How your UK loan monthly payment is calculated

UK loans—personal, car finance, or mortgage—are typically repaid in fixed monthly installments. Each payment covers interest (the cost of borrowing) and principal (reducing what you owe). Your monthly amount depends on loan amount, APR, and term. Compare with our personal loan calculator, car loan calculator, mortgage calculator, USA calculator, or Canada calculator.

How to use this calculator

  1. Currency — Pre-set to GBP for UK borrowers.
  2. Enter the loan amount — The principal in pounds you plan to borrow.
  3. Enter the interest rate — The annual rate (APR) your UK lender quoted.
  4. Enter the term in months — 24, 36, 60 for personal/auto; 300 or 360 for mortgages.
  5. Click Calculate — See your monthly payment, total repayment, and total interest in GBP.

Real-world example

A £15,000 personal loan at 8% for 48 months gives a monthly payment of about £366. Over four years you would repay roughly £17,550 in total—£2,550 in interest. Try our car loan calculator or mortgage calculator for other products.

What to know when you shop

Enter the amount you borrow after any deposit. If a broker fee is financed, add it to principal. Compare scenarios—three-year vs five-year, or how a quarter-point affects a large balance.

Frequently asked questions

What is a competitive APR?
It depends on product and risk. Excellent-credit personal loans may sit well below riskier tiers; mortgages and car deals often price lower than unsecured credit. Always compare like-for-like amounts and terms.
How long do UK loans usually run?
Personal loans often range from one to seven years; car finance commonly two to five; mortgages can stretch 25–30 years or more. Shorter terms save interest but raise the monthly cost.
Is interest worked out monthly?
Most installment products accrue monthly on the reducing balance—the approach we use here.
Does this include PCP or lease payments?
No. Those products include optional final payments, mileage limits, or hire-purchase rules. This page is for straight amortizing loans.
Can I trust this instead of a lender illustration?
Use it for planning. Your lender’s formal illustration and credit agreement are binding; small rounding differences can occur.
