If you still have the same primary credit card you signed up for a decade ago, there’s a good chance you’re leaving valuable benefits and rewards on the table. After all, the likelihood of a credit card you picked out long ago still being the best for your wallet is rather small. Not only do new credit cards hit the market all the time, but your spending habits and needs have probably changed quite a bit.

Unfortunately, failing to switch up your primary card can mean missing out on perks and not optimizing the rewards you earn. A recent CreditCards.com survey even found that 23 percent of respondents didn’t redeem their credit card rewards in the previous year. That’s a sign these cardholders don’t have the right card for their needs — or that they don’t have a grasp on the rewards they have or how to use them.

These are all reasons it makes sense to look for a new credit card if you haven’t in the last few years. Simply put, you may not know what you’re missing unless you look. Here’s a rundown of all the ways a new credit card could leave you better off.

You can earn another sign-up bonus

Adding another credit card to your wallet can help you earn one of the best credit card sign-up bonuses on the market today, which are often worth $500 to $1,000 a pop. Earning a sign-up bonus requires a minimum amount of spending within the first few months, but you may be able to reach the threshold if you use your new card for regular spending and bills.

As an example, the popular Chase Sapphire Preferred® Card is now offering 60,000 points when you spend $4,000 within three months of account opening. That means you would need to use the card for at least $1,334 per month in spending for the first three consecutive months in a row. Although a $95 annual fee applies, these points are worth $750 in travel through the Chase Ultimate Rewards portal or $600 in cash back, statement credits, gift cards and more.

Get a card with a better rewards rate

Maybe your old primary card doesn’t offer rewards, or perhaps it has a disappointing earning rate that’s less than you can find with the best credit cards today. In any case, comparing new rewards credit cards can help you get a better deal.

For example, there’s absolutely no reason to use a card that earns less than 2 percent cash back since there are several 2 percent back credit cards with no annual fee. There are also cards that offer bonus points in different categories you may be able to maximize, but you’ll never know unless you check.

Qualify for an introductory 0% APR offer

If you’re paying debt off on a credit card with a high interest rate, picking up a new card could save you hundreds (or even thousands) of dollars in interest. That’s because an array of cards offer a 0 percent intro APR on purchases, balance transfers or both for up to 21 months.

As just one example, the BankAmericard® lets new cardholders save with a 0 percent intro APR on purchases and balance transfers made within 60 days for 21 billing cycles (followed by a variable APR of 15.74 percent to 25.74 percent). While a 3 percent balance transfer fee applies if you use this card to consolidate other high interest debt, avoiding interest charges for 21 months can help you save money and pay down debt faster.

Your credit score may have improved

Has your credit score improved since you signed up for your current primary card? If so, it’s likely you are now eligible for a much better credit card with a robust selection of perks and features. The fact is, there’s a huge difference between credit cards for fair credit and credit cards for good credit and what they have to offer.

With a good credit score or better, or any FICO Score of 670 or higher, you may be eligible for a credit card with a generous sign-up bonus, a lucrative rewards rate, travel perks and more.

A major life event may have changed your needs

It’s also highly possible that, over the course of many years, a major life event (or several) impacted the way you spend and use credit. If you have kids, for example, a credit card that lets you earn cash back on grocery purchases, daycare spending, diapers and other household supplies may now be essential. Or, maybe you never traveled much in the past, but a new job has you on the road (or in the air) at least once a month.

Whatever has happened in your life over the last decade or longer, there’s a good chance a different credit card could suit your updated needs better. This could mean switching from a card with no rewards to a cash back credit card, or upgrading to a travel credit card so you have perks like airport lounge access or elite hotel status.

You’re paying too many fees

Maybe your old credit card has an annual fee and you’re not sure what you’re getting in return, or perhaps your card charges foreign transaction fees when you use it overseas. In any case, there’s no reason to pay regular fees for a card unless you’re absolutely sure the perks you’re getting are well worth it.

If you’re paying fees and you know you’re not getting commensurate value, now is a good time to explore new options.

The bottom line

Keeping the card you’ve had forever is probably the easiest thing to do, but it may not be the best. You could be missing out on perks and rewards you don’t even know about, but you won’t find out unless you explore new card offers and give one of them a try.

Also, remember that you don’t have to close your old primary card. In fact, your credit score will be better off if you keep old accounts open for the long haul.
