What a cashback credit card does
A cashback credit card returns a percentage of what you spend back to you as cash or a statement credit. You make a purchase, the card issuer pays the merchant, and then a portion of that transaction amount goes into a cashback account tied to your card. That money is yours to keep — you can usually withdraw it, use it to pay your bill, or let it accumulate.
The catch is that cashback is only a benefit if you pay off your balance in full each month. If you carry a balance and pay interest, the interest charges will almost always exceed the cashback you earn. A card offering 2% cashback costs you nothing to use if you pay in full; it costs you money if you don't.
Key Takeaways
- Cashback only saves you money if you pay your full balance monthly — interest charges will erase the benefit if you carry a balance.
- Cashback rates vary by card and sometimes by category (groceries, gas, restaurants), so compare the cards you're considering against your actual spending pattern.
- You need good credit (usually a score of 670 or higher) to be approved for most cashback cards with competitive rates.
- Annual fees on some cashback cards can be $95 or more, so calculate whether the cashback you'll earn exceeds the fee before you open the account.
How cashback rates work and what they actually mean
Cashback is expressed as a percentage of your spending. A 1% cashback card returns $1 for every $100 you spend. A 2% card returns $2 per $100. Some cards offer higher rates in specific categories — for example, 3% on groceries and gas, 1% on everything else — and lower rates if you don't meet a spending threshold.
The percentage is fixed once you're approved; it doesn't change based on how much you spend or how long you hold the card. Some cards cap the cashback you can earn per year or per category, so read the terms before you assume the rate applies to all your spending. A card might offer 5% cashback on groceries but only up to $1,500 per quarter, after which it drops to 1%.
The issuer pays for cashback by charging merchants a fee (called an interchange fee) when you use the card. That fee is built into the price of goods and services, which is why cashback cards sometimes have annual fees — the issuer needs to offset the cost of paying you back.
When a cashback card saves you money versus when it doesn't
Cashback saves you money only if you meet two conditions: you pay your full balance every month, and the cashback you earn exceeds any annual fee.
If you spend $10,000 per year on a 2% cashback card with no annual fee, you earn $200. That's a real reduction in what you pay. But if the same card charges a $95 annual fee, your net benefit is $105 — still positive, but smaller. If you spend only $3,000 per year, you earn $60, which doesn't cover the fee at all.
If you carry a balance, the math reverses. A typical credit card charges 18% to 24% annual interest. On a $5,000 balance, that's $900 to $1,200 per year in interest. Even a 2% cashback card earning $100 per year leaves you $800 to $1,100 behind. In this scenario, the card is costing you money, not saving it.
Credit score requirements and approval odds
Most cashback cards with competitive rates (2% or higher) require a credit score of 670 or above. Some require 700 or higher. If your score is below 670, you may still be approved for a cashback card, but the rate will be lower — often 0.5% to 1% — or the card will have a high annual fee.
Your credit score reflects your payment history, how much debt you're carrying, and how long you've had credit accounts. If you're new to credit or recovering from missed payments, you may not may have access to for the best cashback offers. In that case, a card with a lower rate and no annual fee is a better choice than stretching for a premium card you won't be approved for.
Comparing cashback cards to other rewards options
Cashback is one type of credit card reward. Other cards offer points or miles that you redeem for travel, merchandise, or statement credits. The choice depends on what you actually want to do with your rewards.
Cashback is the simplest to use: the money goes directly to you with no redemption required. Points and miles require you to book through the card's portal or transfer them to a partner, which adds complexity. However, points and miles can sometimes be worth more than their cash equivalent if you're willing to spend time finding the right redemption. A point worth 1 cent in cash might be worth 1.5 cents if you use it for a specific airline ticket.
If you want the reward to be straightforward and useful no matter how you spend, cashback is the better choice. If you travel frequently and want to maximize the value of your rewards, a points or miles card may be worth the extra effort.
How to use a cashback card without overspending
The biggest risk with a cashback card is spending more than you would have otherwise just to earn the reward. A 2% cashback rate sounds good until you realize you spent an extra $500 to earn $10. That's a net loss.
To avoid this trap, treat the cashback as a bonus on spending you were already planning to do, not as a reason to spend more. Use the card for regular expenses — groceries, gas, utilities, subscriptions — that you'd pay for anyway. Don't open new spending categories or increase your budget just because the card offers a reward.
Set a reminder to pay your balance in full before the due date each month. If you miss a payment, you'll owe interest that will wipe out months of cashback earnings. Many people find it helpful to set up automatic payments for the full balance, which removes the risk of forgetting.
Annual fees and whether they're worth it
Some cashback cards charge annual fees ranging from $95 to $450. These cards typically offer higher cashback rates or additional benefits like travel insurance or airport lounge access. Whether the fee is worth it depends on how much you'll spend and earn.
A card with a $95 annual fee and 2% cashback breaks even if you spend $4,750 per year ($95 ÷ 0.02 = $4,750). If you spend more than that, the fee is worth it. If you spend less, a no-annual-fee card with a lower cashback rate will save you more money.
Some issuers waive the annual fee for the first year, which gives you a chance to test whether the card fits your spending. Others offer a statement credit that offsets the fee if you meet a spending threshold in the first few months. Read the terms carefully before you commit to paying an annual fee.
Frequently Asked Questions
Can I use a cashback card if I have fair credit?
Yes, but the cashback rate will likely be lower than cards for people with good or excellent credit. You may find cards offering 0.5% to 1% cashback with no annual fee, or higher rates with a fee. Compare the total benefit (cashback earned minus any annual fee) against your expected spending before you open the account.
What happens to my cashback if I close the card?
Cashback you've already earned is yours to keep — most issuers will pay it out or let you use it as a statement credit. However, some cards have terms stating that pending or unredeemed cashback is forfeited if you close the account. Check your card's terms before you close it.
Do I have to use the cashback right away or can I let it build up?
Most cards let you accumulate cashback indefinitely. You can redeem it whenever you want, use it as a statement credit, or transfer it to a bank account. Some cards have a minimum redemption amount (like $25), so small balances may not be redeemable until they reach that threshold.
Will opening a cashback card hurt my credit score?
Opening a new card will cause a small, temporary dip in your score because the issuer will run a hard inquiry and you'll have a new account with no history. The dip typically recovers within a few months. The long-term impact is positive if you use the card responsibly and pay your balance in full.
Can I earn cashback on balance transfers or cash advances?
No. Cashback is earned only on purchases. Balance transfers and cash advances don't earn rewards, and they usually carry higher interest rates and fees. Avoid using a cashback card for these transactions.
