I remember something about this from my school lessons, but can sombody tell me what the calculation is for APR? I think it involves Principle (amount), Time (in months) and Rate (flat rate interest).

Or am I talking nonsense?

Good Advice Grumbler, you have saved me typing it up

APR can be deceptive though as it is based on borrowing £1500 for 1 year and includes fees as well as interest... hence why Natwest Black credit card, which requires an applicant to have min earnings of £70k, has an interest rate of about 12% but an APR of 50% because of the £250 annual fee.

Thanks everyone - I had seen the links with the explanations of the terms, butwith a bit more surfing, I've managed to find calculations that I had been looking for and can incorporate them into an excel spreadsheet to give me what I'm looking for.

An easy way is to consult a table because otherwise you need a scientific calculator. I hope this helps:

The above post is about monthly rates and annual rates.

The APR is a rate defined in the Consumer Credit Act of 1974
