Points and miles can be earned with fair credit.

The most important of our credit card commandments is to follow it. Even if you are, you never know when you'll miss a payment or get hit with a large purchase that will take you longer to pay off. You have to keep an eye on your annual percentage rate.

We will give you some tips on what to look out for when it comes to your credit card's interest rate.

Keep tabs on your APR

It is possible for the bank that issued your credit cards to change your interest rate at any time, but you won't be notified about it.

You've probably received plenty of emails from the bank on how to use your rewards points and why you should use your card's mobile payment system but we're willing to bet you haven't received any reminders to monitor yourAPR or notifications that it's gone up

This makes sense even though it's frustrating. Banks don't want you to notice that you might have to pay them more. Many credit card interest rates have gone up as interest rates have gone up. If you haven't checked your credit rating in a while, you may be surprised to know what it is.

Choose a balance transfer

You may not be able to get a lower interest rate if you have been carrying debt for a long time. A couple of percentage points won't make a difference. You should look at a card with a balance transfer offer to move your debt to a card with a low interest rate.

Remember to pay off the balance before the interest kicks in.

Bottom line

If you want to succeed in the world of points and miles, you need to stay on top of theAPR on your cards.

It's time to shift your focus if you've gotten ahead of yourself and been carrying a balance. Pay off your debt and improve your credit score by locking in a lower interest rate.
