We talk about travel credit cards quite a bit here at TPG. Applying for and using these cards strategically can unlock incredible travel experiences such as premium class flights or luxurious hotel rooms. However, there are a number of misconceptions out there when it comes to credit cards, and these can stand in your way of not only fantastic rewards but also an excellent credit score.

Today, we're debunking an important myth that involves the number of credit cards you have.

Myth: Having many credit cards will hurt your credit score

At the time of publication, I have 22 open (and active) credit cards. This number strikes many of my friends and family members as off-the-wall, and the most common comment I get is, “Aren’t you worried about what all of those cards will do to your credit score?”

In reality, I’m not worried about what they do to my score. Instead, I am enjoying the boost they have on my score.

In order to debunk myths surrounding credit cards, it’s essential to understand the different factors that contribute to your FICO score, the one most frequently used to determine your creditworthiness for any new line of credit:

  • Payment history
  • Amounts owed
  • Length of credit history
  • New credit
  • Types of credit used

However, not all factors are treated equally, and these five are weighted based on how important they are to your score:

When it comes to opening a large number of credit cards, it’s the two most important factors that come into play: payment history and amounts owed.

Payment history

The single biggest factor in your FICO score is your payment history, which covers any type of credit or installment account linked to your name. While one or two late payments won’t completely ruin your score, it can have a negative impact.

So how does having multiple credit card accounts help this factor? It all comes down to painting a positive picture of your overall credit — and MyFico.com even points out that having multiple accounts with no late payments is a positive.

For example, let’s say you have a single credit card and were late on two or three payments several years ago. Even though you’ve made up ground by paying on time ever since, you’re still 0 for 1 when it comes to accounts showing a late payment. If you add new cards to your wallet and aren’t late on any payments, you now have accounts with unblemished records. This may not move your score from 500 to 700, but in the long run, it’s an undoubtedly positive pattern.

Amounts owed

The second most important factor in your FICO score is the amounts owed, commonly referred to as your credit utilization rate. This looks at how much of your credit you are actually using and is typically expressed as a percentage. Here’s the calculation:

Total balance on your account(s) ÷ Total limit of accounts = Utilization

Keeping this number low shows issuers that you can effectively manage your credit lines and aren’t at risk of over-extending yourself.

Let’s say that you typically have a $2,000 balance on a credit card (paid off in full each month, of course), and your single card has a $10,000 limit. You thus have a utilization rate of 20% ($2,000 ÷ $10,000).

However, if you apply for another card and get another $10,000 of credit, you are now spreading that $2,000 balance across double the available credit. Your utilization drops to 10%.

Let’s extend this math out to even more cards with that same $10,000 credit limit and the same $2,000 in monthly spending:

  • Three cards: $2,000 ÷ $30,000 = 6.67%
  • Four cards: $2,000 ÷ $40,000 = 5%
  • Five cards: $2,000 ÷ $50,000 = 4%

My cards have a huge amount of available credit on them (over $300,000), but my utilization rate regularly hovers around 2%. I don’t spend more on the cards just because I have them. What I am spending is just spread out across a broader credit line, helping my utilization rate and thus improving my credit score.

All that being said, it’s important to note that there are situations where having too many credit cards can impact your credit score. Spending beyond your means (and not paying your balance in full) is a quick way to wreck your score, and adding untrustworthy authorized users can also have a negative impact. Remember too that you should do everything possible to avoid missing payments.

Bottom line

There are many myths about credit cards out there, and a common one relates to the perceived negative impact that multiple accounts can have on your credit score. In reality, the opposite is true, as almost two-thirds (65%) of your FICO score is determined by factors that can actually be enhanced with additional accounts. As always, be sure that you aren’t over-extending yourself, as this myth can easily come true given the right (or wrong) environment.
