How do you interpret an APR rate?

APR (Annual Percentage Rate) shows the true yearly cost of borrowing, not just the interest rate. When you take out a mortgage or loan, the interest rate tells you the cost of borrowing, but it doesn’t include other charges. APR does, combining the interest rate with fees like arrangement, broker, or compulsory charges into a single yearly percentage.

This makes it easier to compare different mortgage or loan deals fairly. Two products may have the same interest rate, but if one has higher fees, its APR will be higher — meaning it costs more overall.

  • Interest rate = cost of borrowing

  • APR = interest rate plus fees, shown as a yearly figure

For mortgages, interest rate affects monthly payments, while APR shows the long-term value of the deal. A lower APR usually means a better overall deal, but it’s important to consider how long you’ll keep the mortgage and your monthly payments.

Understanding APR helps you make informed choices and pick a mortgage or loan that truly fits your budget and goals.

What’s the method for calculating loan payments?

When you take out a loan in the UK, your monthly payment is made up of two parts: the money you borrowed (capital) and the interest the lender charges. Most loans, like personal loans or mortgages, use amortisation, which spreads payments evenly over the term.

Here’s how it works:

  • Monthly payments are fixed for the term of the loan.

  • Early payments mostly cover interest.

  • Later payments mainly reduce the capital.

  • By the end of the term, the loan is fully repaid, including all interest.

Lenders calculate payments using the loan amount, the interest rate, and the loan term. For example, a £10,000 loan at 6% over 3 years gives a fixed monthly payment that gradually shifts from paying interest to paying off the capital.
