Card comparison
All four cards run against your entered spend, foreign-spend share and crypto-funded-spend share at once. Net annual reward = cashback + perks value − annual fee − FX cost − crypto conversion spread cost − staking opportunity cost. The best net reward is highlighted.
| Card | Cashback | Fee + FX + spread + stake cost | Net annual reward | Effective rate |

How it works
Cashback value is your annual spend × cashback rate — the full amount, since every card pays this on the whole spend total. The FX fee only applies to the slice of spend you marked as foreign-currency: foreign spend × FX fee%. The conversion spread only applies to the slice funded from a crypto balance instead of cash or a stablecoin: crypto-funded spend × spread%. Perks value (free Spotify/Netflix-type reimbursements) is added; a subscription-style annual fee is subtracted; and if a tier requires locking capital (Crypto.com's CRO-staking tiers) instead of paying a fee, that locked amount is multiplied by your assumed forgone yield to turn it into a comparable dollar cost. Net annual reward is the sum of all of that, and effective rate is simply net reward divided by total spend — the single number that lets a 1.5%-cashback fee-free card beat a 5%-cashback card once fees, FX and locked capital are accounted for.
Reading the comparison
At the defaults — $24,000/year spend, 15% of it foreign-currency, 20% funded from a crypto balance — Coinbase Card's 1% baseline cashback (its "up to 4%" only applies to whichever volatile token it is promoting that quarter, not to majors or fiat spend) pays $240, with no fee and no FX cost, but its ~2.49% conversion spread on the crypto-funded slice ($4,800 × 2.49%) costs about $120, netting roughly $120/year. Crypto.com's Ruby Steel tier pays 2% cashback ($480) plus a $132/year Spotify-reimbursement perk, minus its $43/year subscription, minus a 3% FX fee on the $3,600 foreign slice (~$108) and a 1.5% spread on the crypto-funded slice (~$72) — netting around $389/year, the strongest of the four at this profile. Gemini's blended ~1.5% cashback across its gas/dining/grocery categories pays $360 with zero fees anywhere, netting the full $360. Nexo's Platinum tier pays 2% ($480) minus a small 0.2% FX cost (~$7) and an estimated 0.5% spread (~$24), netting about $449 — the actual winner here once the numbers are run, ahead of Ruby Steel by a thin margin. Push annual spend toward $60,000 and the ranking can flip again: fixed costs like Ruby Steel's $43 fee shrink to a rounding error relative to its higher 2% rate, while cards with a percentage-based FX or spread cost keep scaling with spend. That is exactly the kind of ranking flip a flat listicle percentage can never show you.
FAQ
Which crypto cashback card actually pays out the most in a year?
It depends entirely on your spend profile, not the headline percentage on the card's landing page. A card advertising 5% cashback can lose to a 1.5% card once you subtract its annual fee, foreign exchange fee on travel spend, and the conversion spread charged when you fund purchases from a crypto balance instead of a stablecoin or fiat one. Crypto.com's top Obsidian tier pays 5% but requires roughly $450,000 in CRO staked for a year to unlock it, so for almost every real spender the mid-tier Ruby Steel or Royal Indigo levels, Gemini's category-based card, Coinbase Card's fee-free structure, or Nexo's Platinum tier will produce a higher net number. This calculator runs your actual annual spend, foreign-spend share and crypto-funded-spend share through all four cards' published rate structures at once so you can see net dollars, not marketing percentages.
Why does the same card show a different net reward depending on my spend mix?
Because four of the calculator's cost lines scale with different slices of your spending, not the total. Cashback applies to your full annual spend. The foreign exchange fee only bites the share of spend you flagged as foreign-currency — someone who never travels pays it on $0. The conversion spread only bites the share of spend funded from a crypto balance rather than cash or a stablecoin — someone who always taps a linked bank account or USD balance pays it on $0 too. A subscription fee or CRO-staking opportunity cost is fixed regardless of spend. Two people with identical annual spend but different habits — one who travels a lot and pays with a crypto balance, one who spends only at home in fiat — can get opposite rankings from the same set of four cards, which is exactly why a single blended cashback percentage on a listicle is not enough to decide.
What is the CRO-staking opportunity cost line and why does it matter for Crypto.com's higher tiers?
Crypto.com's Rose Gold and Obsidian tiers waive the monthly subscription fee in exchange for locking a large CRO balance — roughly $4,860 and $486,000 respectively at current published terms — for a 12-month staking period. That locked capital is not available to earn yield anywhere else for a year, which is a real cost even though no invoice ever gets sent. This calculator lets you set an assumed forgone annual yield (default 4%, a conservative stablecoin/savings benchmark) and multiplies it by the locked amount to turn that opportunity cost into a dollar figure subtracted from the card's net reward, the same way it subtracts a subscription fee for the lower tiers. Set it to 0% if you would not have put that capital to work elsewhere anyway.
How is the breakeven spend between two cards calculated?
Every card's net annual reward is a straight line in your annual spend once your foreign-spend share and crypto-funded-spend share are fixed: reward = (effective rate) × spend + (perks − fee − staking opportunity cost). Two cards' lines cross at exactly one spend level, found by setting the two equations equal and solving for spend. Below that crossing point the card with the better fixed side (lower fee, more perks, less locked capital) wins even though its percentage rate may be lower; above it, the card with the higher effective percentage rate wins because the fee difference gets diluted across more spend. The calculator solves this automatically for your top two cards and reports the exact dollar spend level where the ranking flips.
