How frequently should i check my credit report and score?

Credit Bureaus like Experian, Equifax, and TransUnion offer you to check your credit score once a year. You must adopt one simple strategy. Every 4 months you must contact any single agency and request them to give you a credit report.
Repeat this strategy after every 4 months * 3 credit bureaus.
Your problem is over for 12 months.
That’s enough. Try to do nothing more than it.

Thanks!

You can check twice a year. There are free credit check available .

That's a great idea Ryan. i have not applied this strategy before. Will do it this year. At least, this way, I won't have to pay a penny. ''

OP: Credit report and score can change within a month. It's that fast. So, it's better you check them at least 4 times in a year.

Last year, my credit score increased by 30 points within a month after credit utilization ratio dropped.

Well, I completely agree with Ryan Miller! That's a great idea to keep a check on your credit report and credit score. And that too at free of cost! If you want to check it 3 or 4 times, you need to pay a fees for that!
And my suggestion would be to make payments on time and keeping your credit utilization ratio below 30%! Hopefully, you will be able to maintain a decent credit score!
