What is APR?
What you'll learn
Understand what APR is and what borrowing actually costs you over time.
APR (Annual Percentage Rate) is the yearly cost of borrowing, shown as a percentage. It bundles the interest rate together with certain compulsory fees, which makes it a fairer way to compare two deals than the headline interest rate alone.
The number on its own does not tell you the full cost. What you actually pay depends on three things:
- The rate (the APR).
- The balance (how much you owe).
- The time (how long the debt runs).
A low APR on a big balance carried for years can still cost more than a high APR cleared quickly.
How time stacks the cost
| How you repay | What happens to the balance | Total interest |
|---|---|---|
| Clear it fast | Falls quickly | Lowest |
| Steady extra payments | Falls steadily | Moderate |
| Minimum payments only | Falls very slowly | Highest by far |
On interest-bearing debt, the minimum payment is often mostly interest. The balance barely moves, so the debt lingers and the total cost climbs. This is how a small purchase can quietly cost double over time.
The lever you control
You cannot always change the rate. You can change the time. Every extra pound aimed at the balance shortens the run and cuts the interest you will ever pay. That is why, in our view, clearing high-cost debt faster is one of the more dependable ways to keep more of what you earn.
Key takeaways
- APR is the yearly cost of borrowing - interest plus certain compulsory fees.
- Total cost depends on the rate, the balance and the time, not the rate alone.
- Minimum payments are often mostly interest, so the debt lingers and costs more.
- Paying faster is the lever you control, and it cuts total interest directly.
Illustrative only: a £1,000 balance at an assumed 25% APR, showing roughly how much interest can build up the longer it stays unpaid. Real costs depend on your rate, repayments and provider. Not a forecast.
Frequently asked questions
Is APR the same as the interest rate?
Not quite. APR is meant to capture the interest plus certain compulsory fees, expressed as a yearly figure, so it is a fairer way to compare two borrowing deals than the headline interest rate alone.
Why does a low APR still cost a lot?
Because cost depends on the balance and the time as well as the rate. A modest APR on a large balance carried for years can add up to a serious sum.
Does paying the minimum each month clear the debt?
It keeps the account in good standing, but on interest-bearing debt the minimum is often mostly interest, so the balance falls very slowly and the total cost balloons.
