Cash back
A rewards structure that earns a percentage of each purchase back as a cash equivalent — typically 1–6% — paid as a statement credit, direct deposit, or check. The most straightforward credit card rewards format; the right choice for cardholders who do not value points or miles for travel.

Cash back is the simplest rewards format the US credit card industry offers. Every dollar charged to a cash-back card earns a stated percentage back, denominated and redeemed in US dollars without conversion or transfer mechanics. A 2% cash-back card on $30,000 of annual spending earns $600 a year; a 1.5% card earns $450; a card with category multipliers (3% on groceries, 1% on everything else) earns somewhere in between depending on the mix. Cash back has no valuation ambiguity — a dollar of cash back is worth a dollar.
The cash-back rewards structure in the US market has three sub-formats. Flat-rate cards (Citi Double Cash at 2% all-purchases, SoFi at 2%, Wells Fargo Active Cash at 2%, Capital One Quicksilver at 1.5%) pay the same rate on every dollar spent. Category cards (Chase Freedom Flex at 5% rotating quarterly categories, Discover it Cash Back at 5% rotating quarterly) pay an elevated rate on specified categories up to a cap, usually $1,500 per quarter, then drop to a base rate. Tiered cards (Bank of America Customized Cash Rewards, Chase Freedom Unlimited) pay different rates on different categories with various caps. The right choice depends on whether your spending is concentrated in identifiable categories or spread broadly.
The economics of flat-rate vs category cards is well-documented. For a household with $30,000 of annual spending dispersed broadly across categories, a 2% flat-rate card earns $600. The same spending on a 5%-rotating card with a $1,500-per-quarter cap earns roughly $375 on bonus-category spend ($6,000 × 5%, plus $24,000 at 1% = $300 + $240 = $540), which is less unless the cardholder optimizes the rotation aggressively. For a household with a heavy concentration in a specific category (large grocery bills, frequent travel), a category card with a higher rate in the concentrated category can beat the flat-rate card meaningfully. The math depends on individual spending patterns, which is what the calculator quantifies.
Cash-back vs travel-points math is well-trodden ground in US credit card optimization. For a reader who does not travel internationally on rewards, cash back almost always wins because travel points only outperform when redeemed through high-value channels (transfer-partner award flights at business-class redemptions, hotel chains with substantial discount-to-cash). A reader who does not optimize redemptions captures roughly cash-back-equivalent value from travel points anyway, often slightly less after the operational friction. The general recommendation: if you do not have a clear travel plan that makes points worth more than 1.5 cents each on average, default to cash back.

- Sign-up bonus A one-time reward — points, miles, or cash — that a credit card issuer pays a new cardholder for meeting a minimum spend requirement within a defined window. The most economically important feature of a new card; the bonus typically exceeds five years of ongoing rewards on the same spend.
- Annual fee (credit card) A flat yearly fee an issuer charges for an account regardless of usage. Common on rewards and premium cards, where the math is whether the rewards earned plus statement credits used exceed the fee. The fee is non-negotiable for most cardholders, but issuer retention offers can sometimes waive or refund it.
- Cents per point (cpp) Cents per point is the standard metric for evaluating how much value a credit card reward point is worth when redeemed. A point redeemed for a $10 flight that normally costs 1,000 points is worth 1.0 cpp ($10 ÷ 1,000 = $0.01).
- Travel rewards A rewards structure that earns points or miles redeemable for travel — flights, hotels, car rentals — sometimes at substantially higher cents-per-point value than cash back, particularly through airline or hotel transfer partners. Higher upside than cash back, with more operational complexity.
