Know the rules

Pick the right credit card with math, not marketing

Credit card companies spend billions on advertising because each new approved customer is worth hundreds of dollars in lifetime value. The glossy sign-up bonus, the rotating categories, the “0% APR” banner — all of it is designed to make you feel like you're winning. The only way to know if a card is actually a good fit is to run the numbers on your spending, your credit profile, and your payoff timeline.

This site is built for exactly that. Every tool lets you enter your own inputs — monthly spend, balance, APR, income, credit score — and see the real dollar outcome. Nothing is gated, nothing is sold. When you're ready to apply, you can tap through to the issuer via an affiliate link and we may earn a small commission at no cost to you.

What this site covers

  • Comparisons: Cashback, travel, balance transfer, first-timer, and business cards ranked side by side.
  • Calculators: Rewards value, annual fee break-even, interest cost, minimum payment trap, payoff plan, transfer fee, cash advance cost, churning ROI, and more.
  • Education: What score you need, how authorized users work, store cards vs general cards, and what the fine print actually means.

Start with whichever tool matches your next decision. Every page includes a working calculator, a comparison table, and a PDF export so you can save your numbers and compare cards offline.
