Here's What Happens When You Have Too Many Credit Cards

Just like Barry White says: "Too much of anything is not good for you, baby." And that includes credit cards.

Don't get me wrong, I'm a fan of rewards. And having a small quiver of credit cards to earn cash back and travel perks is awesome. But when you start opening cards willy-nilly and don't have a system to track them all, it can backfire pretty fast.

Here are some things to watch out for when you have too many cards open.

You're more likely to miss a payment

Every new card comes with its own billing cycle and due date. Unless you've got autopay set up or a nerdy spreadsheet system, it's easy to accidentally skip one. And even one missed payment can hurt you.

A single 30-day late payment can drop your credit score by ~80 points. Plus, late fees and interest charges pile up fast if you don't catch it right away. Not exactly the glamorous points-chasing life we all dream about.

You could end up in credit card debt

This is the big one. More cards = more available credit = more temptation to swipe now and think later. It's a slippery slope.

Let's say you carry a balance of $5,000 across multiple cards. At today's average interest rate of 20%+, you could pay over $1,000 per year just in interest. That's money you could be investing, saving, or spending on something fun -- like a vacation booked with rewards points, not debt.

If you've ever thought "well it's just one more charge," that's a red flag. When cards start to feel like fake money, it's time to reassess.

On a serious note, if you do have credit card debt currently, check out these helpful balance transfer offers. Moving your debt to a 0% intro APR card can save you a ton in interest, and help you become debt-free faster.

You might waste money on unused annual fees

Some premium cards come with awesome perks, like airport lounge access, Uber credits, luxury hotel upgrades, you name it. But if you're not actively using those benefits, the fees aren't worth it.

Years ago, I was holding onto a $95 annual fee card for ages even though I wasn't using it. Silly move in hindsight. I ended up downgrading to a no-annual-fee version and saved myself the charge while keeping the account open (which helped my credit history).

If you've got multiple cards with fees, ask yourself: are you truly getting the full value of that card each year?

If not, it might be time to cancel or downgrade to a no-annual-fee card.

So how many cards should you actually have?

There's no magic number, but here's a basic three-card setup that's worked well for me and a lot of folks I know:

1. Your oldest credit card: even if you barely use it, that old credit line keeps your credit history intact and gives your score a nice foundation.
2. A high-earning category card. Think about the single biggest spending category and find a card that gives the highest rewards rate to match.
3. One solid flat-rate cash back card. This is for "everything else."

Anything beyond that should have a specific role, or a solid reason to stick around.

Personally, I open at least one new credit card each year (usually chasing a big $750+ welcome offer). But I have gotten into the habit of canceling cards that I don't use long term.
