This calculator covers the loan itself — principal and interest on a standard monthly-repayment loan. It does not include arrangement fees, insurance or taxes, and it is a guide for comparing offers, not financial advice.
How to use it
Type the amount you want to borrow.
Add the yearly interest rate from the offer (the APR-style figure).
Set the years and read the monthly payment plus the total interest — the number lenders rarely headline.
The two numbers every borrower should know
The monthly payment tells you whether a loan fits your budget; the total interest tells you what it truly costs. Stretching a loan over more years lowers the monthly figure but quietly raises the total — doubling the term rarely halves the payment but often doubles the interest. Run the same amount at two different terms here and the trade-off stops being abstract. The maths is the standard amortisation formula, run on your device; nothing you type is sent anywhere.
