Whether you're borrowing for a car, home improvements, or consolidating existing debt, understanding the true cost of a loan is essential. Our calculators help you see exactly what you'll pay each month, how much interest you'll pay over the full term, and how different loan options compare.
UK lenders use the Annual Percentage Rate (APR) to show the total cost of borrowing, including interest and fees. Our tools break this down into monthly payments and total costs, so you can make informed decisions before committing to any loan.
Frequently Asked Questions
How is loan interest calculated?▼
Most UK loans use amortisation, where interest is calculated on your outstanding balance each month. Early payments contain more interest, while later payments reduce the principal faster. Our calculators show this breakdown clearly.
What's the difference between APR and interest rate?▼
The interest rate is the base cost of borrowing. APR (Annual Percentage Rate) includes the interest rate plus any mandatory fees, giving you the true cost of the loan. Always compare loans using APR for an accurate comparison.
Can I pay off my loan early?▼
Most UK personal loans allow overpayments, typically up to 10% of the balance per year without fees. Our overpayment calculator shows exactly how much you could save by paying extra each month.
