Just realized a lot of people are confused about how much credit they should actually use on their cards. Like, there's a real strategy to this that actually impacts your score more than you'd think.

So here's the thing - credit utilization is basically the percentage of your total credit limit that you're actually using at any given time. If you have a 1000 dollar limit and you're carrying a 500 dollar balance, that's 50 percent utilization. Simple math but most people don't think about it.

The general rule that banks and lenders go by is keeping it under 30 percent. That's the sweet spot. But if you can keep it below 10 percent, even better. I know it sounds strict but your credit score can take a real hit if you go too high. We're talking up to 30 percent of your entire score is determined by this one factor.

What I've noticed is that people either don't know this or they just ignore it. They max out their cards and wonder why their score tanks when they apply for a mortgage or something important. The thing is, how much credit should i use is actually something you can control pretty easily.

If you're consistently using most of your limit, there are a couple moves. You can request a credit increase online through your card issuer - usually pretty painless if you have a decent payment history. Or you can apply for additional cards to spread out your usage. Just don't go crazy applying for everything at once because that can also hurt your score.

The other hack that works is paying down your balance multiple times throughout the month instead of waiting until the statement closes. Your bank might report a lower balance to the credit bureaus on a day when your utilization is actually lower. Takes a bit more discipline but it can make a difference.

One thing I'd avoid though - don't close old accounts thinking it'll help. Actually does the opposite. Closing accounts reduces your available credit, which raises your utilization ratio. Plus older accounts help your credit history length, which is another scoring factor.

Bottom line: aim to keep your overall credit usage around 30 percent or less if you can. It's one of those financial moves that seems small but actually has a pretty big impact on your financial flexibility down the line.
