Loan calculator
Monthly payment and total interest for a fixed-rate loan.
A standard repayment loan with a fixed rate: every payment is the same, and each one pays off a bit more of the balance. Fees and insurance aren’t included.
Three numbers decide a repayment loan: how much you borrow, the rate, and how long you take. This turns them into the two that matter — what leaves your account each month, and what the loan costs in total.
That second figure is the one worth staring at. Stretching a loan from three years to five lowers the monthly payment and raises the total interest, often by more than people expect.
The maths is the standard amortised payment: every instalment is the same size, and the split between interest and principal shifts over time.
How to use it
- Enter the amount borrowed.
- Enter the yearly interest rate.
- Set the length in years.
- Read the monthly payment, total interest and total repaid.
Frequently asked questions
Does this include fees and insurance?
No. Arrangement fees and any required insurance sit on top, which is why an advertised APR is usually higher than the bare interest rate.
What if my rate is variable?
Use it as a snapshot: the figures show what today’s rate implies. A variable loan’s payments change as the rate moves.
Can I see the amortisation schedule?
Not on this page. The headline figures — payment, total interest, total repaid — are what most decisions turn on.
Is my financial information stored?
No. Nothing you type here is sent or saved anywhere.
