How the interest builds up
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.
Lenders may calculate interest differently (some charge it daily), so your actual interest can differ slightly.
Worked example
Borrowing £40,000 at 7.5% over 10 years costs £16,976.85 in interest. Over 20 years the payment falls to £322.24 a month, but the interest more than doubles to £37,336.95.
Think about the total cost
Long terms make secured borrowing look affordable month to month but can make it much more expensive overall. Your home may be repossessed if you don't keep up repayments.

CALCULATOR QUESTIONS
Equity loan interest calculator questions
How much interest will an equity loan cost?
Enter your figures above. For example, £40,000 at 7.5% over 10 years costs £16,976.85 in interest.
Does a longer term cost more?
Yes. Doubling the term in the example adds £20,360.10 in interest.
Why do I pay more interest at the start?
Interest is charged on the balance you owe, which is highest at the start. As you repay, the balance falls and so does the interest.
What's the risk?
Your home may be repossessed if you don't keep up repayments on a loan secured on it.
