working out interest on credit cards

Hello- this is my first post so bare with me.

I am trying to understand how interest is worked out on a credit card that has 35% APR? say i was to use 300 but paid 100 back on time, then planned to pay the rest the following month. What would be the interest and how would i work it out?

Also regarding cash credit card withdrawals which im aware is best avoided. How do i work out interest on those? say its again 35% interest rate and i take out £40 and dont repay it for 60 days.how would i work it out?

Thanks

I just want to be able to understand all the fine print.

    35% APR means 2.53% monthly or 0.082% daily.

    You will pay daily interest on each transaction from the day you make it until £100 is credited to your account, then 2.53% on the remaining £200.

    No it will be 2.35% on the whole £300! If you don't clear the balance completely, ie pay £300 in this case, you will be charged interest on the whole £300 until you pay it off. Also if you then use the card again, you will be charged interest on the new purchases straight away.

    If you read my post again and more thoroughly this time, you will see that I said the same, but more accurately.

    In the region of that amount, yes.

    As a general rule, if you know in advance that you are not going to pay off the credit card in full, then you should send your partial payment, in your case, £100 as soon as you receive your statement online rather than in the post.

    It will save you a little in interest.
