Credit Card Comparison Calculator

An intro APR is a promotional interest rate — often 0% — offered for a limited period when you open a new card. During this window, little or no interest accrues on your balance, which can save you significant money. Once the intro period ends, the regular APR kicks in, so the balance remaining at that point starts accumulating interest at the standard rate.

You enter your current balance, your planned monthly payment, and the details for each card (annual fee, intro APR, intro period length, and regular APR). The calculator simulates a month-by-month payoff for both cards and totals up all interest charges plus annual fees, giving you a true long-term cost for each card.

These tier names are mostly marketing labels used by issuers to signal a card's prestige level. Higher-tier cards (like Reserve or Platinum) typically come with higher annual fees but offer better rewards rates, travel perks, and higher credit limits. Whether a premium card is worth it depends on whether you'll use enough of its benefits to offset the annual fee.

It depends on whether you carry a balance. If you pay your balance in full each month, APR is irrelevant and a lower annual fee wins. If you carry a balance month to month, a lower regular APR will save you far more in interest than you'd save on a small annual fee difference. Use this calculator to see the exact dollar impact for your specific situation.

Total cost is the sum of all interest charges paid over the life of the debt plus all annual fees paid during that same period. It represents the true price you pay for using each card beyond just repaying your original balance.

Lenders use your credit score — built from your credit history — to assess risk. Borrowers with excellent credit (typically 720+) qualify for cards with the lowest APRs and best rewards. Those with fair or poor credit may only qualify for secured cards or high-APR products. Improving your credit score over time can unlock significantly better card offers.

Key terms include APR (Annual Percentage Rate — the yearly cost of borrowing), intro APR (a temporary promotional rate), annual fee (a yearly charge just for having the card), credit limit (maximum balance allowed), minimum payment (the smallest amount you can pay without penalty), and grace period (the window after your statement closes where you can pay in full and avoid interest).

Not necessarily. A 0% intro offer is powerful for aggressively paying down debt during the promotional window, but you need to factor in balance transfer fees (typically 3–5%), the regular APR after the intro period, and any annual fee. This calculator helps you weigh those factors against a card with no intro offer but a lower ongoing rate.
