About Using A Credit Card Payment Calculator

Credit cards are so easy to get these days, and although you may think that would be a good thing, it really is not because it means that lots of people are getting credit cards and using them unwisely, resulting in serious trauma to their credit scores. If you do decide to get a credit card, you really need to make sure that you are responsible with it and that you make each and every payment on time.

There are actually quite a few different tools that you can use to keep yourself on track with your credit card payments, but none are more useful than the credit card payment calculator. The credit card payment calculator is a calculating tool that helps you to get an estimate of what you are going to be expected to pay on your next bill. It can also help you more in the long term of things, by helping you calculate how long it will take you to pay off your credit card debt.

The Details
The typical credit card payment calculator has three separate inputs: credit card balance, credit card interest rate, and payment per month, all of which you need to be aware of. Then there is a single output by the credit card payment calculator, which is the number of months that you will need in order to pay off your credit card.

How to Use it
If you are interested in using a credit card payment calculator, you can usually go directly through your credit card company, for instance through their website, but you can also find free credit card payment calculators to use all over the Internet. Once you learn the method that is used, you can easily do this on your own with just a basic calculator and the required information.

Paying on Time
There are lots of different tips that will be helpful to you in terms of paying off your credit card, but no advice is more crucial than to pay your credit card bills on time. Nothing affects your credit score more negatively than a late credit card payment, and so you really need to make sure that you stay up to date with this and never make a late payment.

You can always get the help of a financial advisor here if you would like extra tips on how to keep your credit in good standing and how to best manage your credit cards. The information was given by a web designer who had much to offer in terms of businesses for sale and online marketing.

how to calculate credit card interest / how long it will take to pay it off?

I need an EQUATION or two. I’m trying to program a credit card debt calculator in PHP to basically tell me this as a result…..

if you currently owe $80,000 in credit cards, and your average interest rate is 20%,

You will pay $159,196.96 in interest,
your total payment will be $239,196.96

and it will take you 54.33 years by paying the minimums.

the only part that i know for sure is to add the two numbers together to get the total amount.. beyond that i’m kind of lost, mostly because i don’t understand how credit card interest works on a deep level.

I understand the “simple interest” model, which is NOT what credit cards work on.. most of the stuff i find on the net is for mortgages and simple interest. that doesn’t help me in this case.

thanks in advance!!

the equations themselves will help.

Let B = credit card balance at the beginning of the month.
Let P = payment made on the credit card for the month.
Let i = monthly interest rate (e.g., if 18% annual, then 1.5% monthly)
Let N = credit card balance at the end of the month.

Assume no purchases or payments are made during the month (except at the end of the month.) Then,

N = B*(1+i) – P

If purchases are made during the month, then redefine B = average credit card balance.
