Credit Cards 101
Why do credit cards exist?
Banks offer credit cards because they are one of their most profitable products.
Every time you swipe your card, the merchant pays a small fee (typically between 1.5% and 3.5% of the transaction) to accept your payment. These fees, called interchange fees, flow primarily to the bank that issued your card. On top of that, banks collect interest from cardholders who carry a balance month to month, as well as annual fees, late fees, and foreign transaction fees. Add it all up, and you can see why banks are very motivated to get cards into your wallet.
Credit cards are in fact so lucrative as a product that other businesses – like hotel chains, department stores, and more – team up with banks to offer co-branded credit cards (e.g., the Chase Marriott Bonvoy Boundless card). These partnerships are a win-win: the bank gains a new cardholder, and the brand builds loyalty. Airlines in particular have gone all-in on credit card products. In fact, for major carriers like United and Delta, their frequent flyer programs (largely fueled by co-branded credit card partnerships) generate more profit than actually flying planes. This explains a trend you may have noticed: frequent flyer programs increasingly reward you more for spending on the airline’s credit card than for miles flown.
What are credit card points?
Because banks earn so much from card usage, they can afford to share a slice of that revenue back with you, the cardholder. Depending on the card, that reward might come as cash back, statement credits, special discounts, or, arguably the best part: points and miles.
Many cards also layer on additional perks beyond the base rewards: complimentary hotel night certificates, automatic airline status, monthly Uber credits, airport lounge access, or travel insurance. These benefits are part of why the “right” credit card for someone isn’t always the one with the highest point earn rate, but instead, it’s the one whose full package of benefits fits your lifestyle.
A closer look: Chase Ultimate Rewards.
Let’s ground this in a real example. Chase offers the widely popular Chase Sapphire Preferred card, which earns reward points across everyday spending categories (as of 2026, for example, the card earns 3x points on dining and 2x points on travel purchases).
Chase’s points currency is called Ultimate Rewards. What makes these points especially powerful is their flexibility: cardholders can redeem points directly through Chase’s travel portal (where points are worth a fixed value), or transfer them to one of Chase’s airline and hotel partners, including United, JetBlue, Air Canada, Hyatt, and Marriott.
That transfer option is where things get interesting — and where savvy points enthusiasts find outsized value. A point transferred to Hyatt, for example, can be worth 2 cents or more when redeemed for a hotel night, which is significantly more than its face value through the Chase portal. We’ll dig into this in detail later.
The points ecosystem can feel overwhelming — but it doesn’t have to.
The points world often creates a lot of confusion, and I’m often asked questions like:
- Which credit card should I use at a restaurant?
- Is it bad to have multiple credit cards?
- What’s the best credit card for my situation?
- Should I book through my credit card’s travel portal or directly with the airline?
- Are airline miles and hotel points the same thing?
- Do points expire?
These are exactly the right questions to be asking, most people never ask them at all. As a result, they either leave significant value on the table or, worse, redeem their hard-earned points for things like gift cards or merchandise at a fraction of their potential worth.
The good news is the basics aren’t complicated once someone breaks them down for you. A relatively small amount of knowledge goes a long way. On this site, you’ll learn practical tips on how to earn more points on your everyday spending, and how to redeem them for maximum value. If the sound of caviar and champagne in the quiet cabin or free nights at luxury resorts sounds enticing, it’s closer than you think, and you’ve come to the right place. There are practical strategies that can unlock fancy travel for a fraction of its cash price: the crown jewel of points enthusiasts!
So, how do I earn points?
There are a few ways to earn credit card points: everyday spending, category bonuses (earning extra points at restaurants, on travel, etc.), and sign-up bonuses. All three matter, but sign-up bonuses are in a league of their own when it comes to accumulating points quickly.
The best way to illustrate why is through a simple example. Let’s say you spend $2,000 a month on credit cards:
- On a card that earns 2x points on all spending, you’d earn 4,000 points that month
- On a card that earns 1x points on all spending, but comes with a sign-up bonus of 40,000 points for your first $2,000 of spending, you’d earn 42,000 points: 2,000 from normal earning, plus the 40,000 bonus
The math is simplified, but the point is real. A single sign-up bonus can deliver more points than an entire year of everyday spending on a premium earn-rate card.
A few important caveats: sign-up bonuses come with eligibility rules, and not everyone qualifies for every bonus. Applying for a new card may also trigger a hard inquiry on your credit report, which can temporarily negatively impact your score (though in the longer-term, inquiries fall off of your account and the amount of credit in your name can help reduce your credit utilization if managed properly). It’s worth doing your homework before applying for any card specifically for its bonus.
