# How do I work out APR's from Monthly Interest Rates

Posts: 49 Forumite
Can anyone please tell me how I work out an APR from a monthly interest rate.

I have two I need to calculate:-

MIR - 2.0084%

MIR - 1.527%

If anyone can help it would be gratefully appreciated.

I expect you multiply by 12, but im not 100%

Id simply call them up, ask, then ask them to lower them while you are on the line
:beer: Well aint funny how its the little things in life that mean the most? Not where you live, the car you drive or the price tag on your clothes.
Theres no dollar sign on piece of mind
This Ive come to know...
So if you agree have a drink with me, raise your glasses for a toast :beer:

I could be having a blonde moment, but surely just multiply by 12?

So ....

MIR 1.527 = 18.324% - APR
MIR 2.0084 = 24.1% - APR

I agree interest is a very funny thing. I used to work for Barclaycard and when we received our initial training 3 weeks was dedicated to learning how interest worked in relation to credit cards.

As you can see the training paid off lol, I can't remember how you extrapulate the APR from the monthly figures

the correct formula to convert a monthly interest rate m to a APR is as follows

expresss m as a decimal so 2% is 0.02

APR = ((1+m) to the power of 12)-1

but multiplying by 13 gives a pretty good approximation and is a lot easier

so 2.0084 per month is APR of 26.95% (multiplying 13 gives 26.11%)
and 1.527 per month is APR of 19.4% (multiplying by 13 gives 19.85%)

in fact multiplying by 12 isn't too bad but it doesn't make any allowance for compound interest.
