Methodology

The ranking is a formula, not an opinion. Every card is scored with the same arithmetic for the stake and spend you set. No field tied to commission enters the score. Formula version v1.2; a change of version is recorded on /changes/.

Net value per year

cashback_yr  = cap.scope == reward ? min(rate × spend_yr, cap × periods)
             : cap.scope == spend  ? rate × min(spend_yr, cap × periods)
             : rate × spend_yr
effective_fx = fx + (conversion_spread ?? (stablecoin card ? 0.5% : 0))
net_value    = cashback_yr
             − annual − 12 × monthly − subscription
             − effective_fx × fx_share × spend_yr
             − stake_usd × 5.0%

Three states of a figure

Confidence

A — an official source plus an independent one (regulator register, network announcement, or our own captured evidence). B — official sources only. C — no verified official figure; net value is not computed and no partner link is shown. Today: A 20 · B 41 · C 7.

How figures are verified

Every figure is extracted from the issuer's own pages, stored as a checksummed snapshot, and quoted on the card page under Sources. A script matches each quote against the snapshot; a quote that cannot be found downgrades the figure to “not disclosed”. 437 figures are verified as of 7 Sep 2026. Figures not checked for 90 days carry a warning on the card.

The extraction itself is done by a language model (Claude): it reads the snapshot and returns each figure with the verbatim sentence it came from. The quote check is what keeps a misread from reaching the page — a figure the model cannot tie to a sentence in the snapshot never becomes verified. Fields the model leaves unsourced, and any two sources that disagree, are checked by the editor by hand before they are published.

Corrections

Report a wrong figure from any card page. We answer within 5 working days; every correction is logged on /changes/ with what it was, what it is now and who reported it.

Scraping policy

One request per five seconds per host, an identifying user agent with a contact address, robots.txt respected. Snapshots are private; only quotes of 25 words or fewer are published.
