Credit Card Recommendation Methodology

The scoring formula

Net annual value = annual rewards + expected credit value − annual fee − complexity penalty.

Annual rewards is the sum of each spending category multiplied by the card's earn rate for that category, with per-card caps applied. If a category has a quarterly or annual cap, spend above the cap is rewarded at the card's base rate (typically 1%).

Expected credit value is the headline value of each statement credit multiplied by a redemption-likelihood factor. Defaults are conservative; you can adjust per credit on the results page.

Complexity penalty is a small flat deduction applied to cards that require quarterly category enrollment, dining/travel portal redemptions, or active perk management to capture full value. It defaults to a few dollars per quarter.

Point and mile valuations

Cash back rewards are valued at 1.0¢ per cent earned. Points and miles are valued at a per-currency rate set on the results page.

Default valuations are calibrated to median transfer-partner redemptions, not the inflated valuations issuers like to advertise. You can edit any currency's valuation up or down if your redemption pattern is different.

When you set preferred airlines or hotels, we boost the valuation of bank-point currencies that transfer to those partners — the boost is largest for partners with limited transfer paths (e.g., a partner that only transfers from one bank gets a bigger boost than a partner served by all banks).

Multi-card combo search

The combo finder evaluates every two-, three-, and four-card combination from the catalog. For each combo, it routes each spending category to whichever card in the combo earns the most after caps. The combo's net annual value is the sum of those routed earnings, plus each card's eligible credits, minus each card's annual fee, minus the complexity penalty.

We default to two-card combos because they capture most of the upside without the wallet management burden of three or four cards. You can change the wallet size on the calculator.

Inputs that change the ranking

Monthly spend per category, cash back vs. travel preference, annual fee tolerance, willingness to manage rotating categories, premium perks appetite, point valuations, preferred airlines, preferred hotels, household status (Costco shopper, Amazon Prime member). Every input is documented in-app and can be changed at any time.

What we deliberately exclude

Welcome bonuses, referral bonuses, hard-to-value soft perks (trip protections, purchase coverage, no foreign-transaction-fee value, elite status accelerators on hotel cards). These matter to some users but distort generic rankings, so we surface them in card detail panels rather than baking them into the headline score.

Open methodology, no affiliate weighting

Card rankings are not influenced by affiliate relationships, advertiser status, or any commercial arrangement. The same formula runs on every card in the catalog. See our editorial policy and disclaimer for our affiliate stance and limitations.

Frequently asked questions

How often is the card data updated?

Card terms (rewards rates, fees, credits) are reviewed periodically. Issuers can change terms at any time, so always verify with the issuer before applying. The catalog version and last-updated date are shown in-app.

Can I see the math for a specific card?

Yes. The results page shows a per-category breakdown for every card, including which categories were capped and how each credit was valued. Click any card to expand the breakdown.

Is CardPilot really free?

Yes. CardPilot is 100% free. There are no accounts, paywalls, or premium tiers. The full calculator and every recommendation is available to everyone.

Does CardPilot affect my credit score?

No. CardPilot only does math on your spending. We never request a credit pull or share your information with issuers. Applying for a card on the issuer's website is a separate action that may affect your score.

Is this financial advice?

No. CardPilot provides educational comparisons and estimates. It is not financial, legal, tax, credit, lending, or banking advice, and it does not guarantee approval. Always verify terms with the issuer before applying.
