Never used credit before, want to make my first credit purchase

I was told to buy something big. Like 100 dollars then pay it off as soon as it post to your credit card. Don't let it go month to month with a balance or you'll pay more in interest fees. But sometimes you get behind and it happens. Don't constantly use up your credit card just because. Make sure you have the money to pay it off and like I said sometimes people are in need and your credit usage becomes high. Also don't use more that 30% on your card.

Don't ever spend more than you can afford to pay off...

Know your credit limit and interest rate... don't ever go over the limit and always pay off what you can...

Those interest rates can be an absolute killer!

Pay back on time and never miss a payment. If it is a loan then generally the early payments are mostly interest. The interest to principal ratio of each payment changes over time. At the end of the loan period your payments are mostly principal so if you have extra cash and can pay towards the principal early on in the loan you can reduce the amount of interest you pay over the course of the loan.

Credit card interest rates are generally high so carrying a balance gets expensive.

Never miss a payment and try to repay more than the monthly due balance.

Pay your bill on time.

Some merchants provide cash discounts. And if you want to avoid interest, you need to pay off your bill in full at the end of the month.
