How the interest rate shapes the cost
Interest is worked out each month on the balance you still owe, at one twelfth of the annual rate. Early payments are mostly interest; as the balance falls, more of each payment repays the loan.
Loans against property often run for many years, so even a small difference in the rate adds up. Enter the rate from each quote to compare the total interest side by side.
Lenders may calculate interest differently (some charge it daily), so your actual interest can differ slightly.
Worked example
Borrowing £50,000 at 9% over 10 years costs £633.38 a month and £26,005.46 in interest, 52.0% of the amount borrowed. £4,368.85 of that is paid in the first year.
Over 5 years the payment rises to £1,037.92 but the interest falls to £12,275.07. Over 15 years the payment drops to £507.13, but the interest rises to £41,283.99.
Fixed or variable rates
Some loans against property have a fixed rate, others a variable rate that can change. This calculator assumes the rate stays the same for the whole term, so if yours can rise, try a higher rate to see the effect.
Your property may be repossessed if you don't keep up repayments on a loan secured on it.

CALCULATOR QUESTIONS
Loan against property interest rate calculator questions
How much interest will I pay on a loan against property?
Enter your details above. For example, £50,000 at 9% over 10 years costs £26,005.46 in interest.
Why is the first year's interest so high?
Interest is charged on what you owe, which is highest at the start. In the example, £4,368.85 is paid in the first year.
Does a shorter term save interest?
Yes. In the example, 5 years instead of 10 saves £13,730.39 of interest, though the payment is higher.
What's the difference between the interest rate and the APR?
The interest rate is what's charged on the balance. The APR also includes most compulsory fees, so it's better for comparing the overall cost of different loans.
