Working out minimum payment
I am getting frustrated with my credit card, can someone help me with my spreadhseet?
I keep a sheet that works out the next minimum payment but I just can't get the logic right. I have done a transfer offer of 4.9% to hold some money I am moving around.
so - I have a balance of £2952.12 in A1
the minimum payment is 1% (B1) + interest (C1). The interest is 4.9%
I have tried =SUM(A1*B1*c1) but thats way off at £1.45 - I have tried numerous options but can't get close to what I am being charged last month, which is
£42.42 last month and the proposed this month is £41.22
can anyone help?

Re: Working out minimum payment
Surely the rate of interest doesn't come into the equation when calculating the minimum payment?
I would think it should simply be balance x percentage required, i.e. A1 x B1
Having said that, given the repayments you quote, they are actually taking somewhere in the region of 1.4% so something doesn't add up.

The declared rate of 4.9% is an annualised equivalent. You need to find out what the monthly rate is.
It isn't either .049/12 or (1.049)^(1/12) -1 as neither quite reproduce the quoted interest.
They may even be using a daily rate, but I couldn't quite make that work either.
A daily rate might be (1.049)^(1/365)-1, again that doesn't quite fit.
Anyway, what you are doing wrong is treating the 4.9% as a monthly rate. Once you fix that, there are any number of possible formulae.

Re: Working out minimum payment
Second thoughts...
Alaric is, of course correct that calculating the actual monthly interest is not necessarily straightforward. Having said that, it is possible to get close to the figure required, but your formula appears not to be correct.
The repayment required is (A1*C1)+(A1*B1) in other words, the sum of balance x rate and balance x minimum percentage.
You will probably need a different calculation for the A1*C1 to get close to how they actually calculate the interest.

Re: Working out minimum payment
The calculation method should be buried in the card T&Cs somewhere I assume ?

You need to establish C1. What it isn't is the quoted annual rate. 4.9% a month would be Provident Financial sub-prime territory.
Try a bit of reverse engineering. 1% of the sum outstanding is 29.52. Subtract that from the amount they ask for (41.22) gives 11.70. Expressed as a % of the sum outstanding (2952.12) is 0.396% which annualises to 4.9% if you round to 1 decimal place in the quoted percentage.
You need an investment paying at least 5% to want to borrow at 4.9% unless it's just spending.

Re: Working out minimum payment
Ahh of course, thanks so much I hadn't taken into account that was the annual rate! Obvious when you say that.
Its just a short term borrowing to buy a new car while I wait for some money to come in to pay it straight off again. So I just put it on the credit card.

Its a bit ambiguous:-
The minimum monthly payment on your credit card is 1% of the amount borrowed plus interest and any late, overlimit or annual fees in most cases.
Here’s how it works:
If you’ve got a balance of £25 or less, you’ll have to clear the balance on your statement.
If your balance is more than £25, your payment will be £25 or 1% of the balance on your statement, whichever is the greater. We’ll also add an amount equal to the default charges, card fees and interest for that month to the payment due.

Re: Working out minimum payment
I get pretty close doing this:
1% of £2952.12 = £29.52
Interest due on £2952.12 @ 4.9% p.a divided by 365 (daily amount) multiplied by 30 = £11.89
Total £41.41
Does that help at all?
The chances of getting the calculation exactly "right" are probably small as you have make assumptions about the bank's rules for leap years, days in the month, what day is the first day of interest etc. Within 50p is probably close enough for most purposes??

Can't you get a 0% interest rate card, and juggle about balances so you don't pay any interest?
There was a name for that ruse, but I can't remember it now...

Re: Working out minimum payment
The issue with most 0% cards is the BT fee. Fine if you use it for the length of the balance but this is going to be short term. Hopefully I spend less in interest than just paying a fee!
I converted the apr to an annual amount as suggested using my own stoozing.com Apr convertor and it was spot on this month.

Re: Working out minimum payment
There are a few 0% fee 0% balance transfer cards. Halifax currently has one for 29 months. Bank of Scotland and Lloyds also have 25 months. Have a look at uswitch.com for 0% balance transfer cards, and sort them on the fee. You have to do the balance transfer in the first 90 days.
They won't transfer a balance from an American Express card (no idea why, but I have tried Lloyds and Halifax and neither can manage it).

I have a 0%apr, 0% fee from both Tesco and Bank of Scotland. I struggled to transfer an Amex balance so stoozed via a MBNA card.
