Both are $0-annual-fee flat-rate cash-back cards — the two most common answers to "what's a simple no-fee card that just works." Citi Double Cash earns 2% on every purchase (1% when you buy, 1% more when you pay it off); Quicksilver earns a flat 1.5%. On pure earnings math, Double Cash returns 33% more per dollar. Quicksilver's edge is no foreign transaction fee (Double Cash charges 3% abroad) and a slightly broader acceptance network. Source: citi.com and capitalone.com, Q2 2026.

Citi Double Cash earns 2% on every purchase (1% when you buy, 1% more when you pay it off); Capital One Quicksilver earns a flat 1.5%. On $20,000 in annual spend, Double Cash returns $400 vs Quicksilver's $300 — a $100 difference with no annual fee on either card. For most flat-rate cash-back seekers who pay their balance in full, Double Cash wins on raw earnings. (Source: citi.com; capitalone.com.)
Citi Double Cash charges a 3% foreign transaction fee on purchases made outside the U.S. Capital One Quicksilver has no foreign transaction fees. For international travel or shopping on foreign websites, Quicksilver saves more on those transactions despite its lower base earn rate. For domestic-only spend, Double Cash's 2% wins. Verify current fee terms at citi.com and capitalone.com.
Citi Double Cash earns ThankYou points that redeem at ~1 cent each for cash back on their own — but if you also hold a Citi Strata Premier, you can combine points and transfer to airline partners (JetBlue, Turkish Airlines, etc.). Capital One Quicksilver earns cash back (not Capital One Miles) with no transfer path; to access Capital One's travel transfer network you'd need a Miles card such as Venture or Venture X. Double Cash has the edge if you're building toward a transferable-points ecosystem. (Source: citi.com; capitalone.com.)
Both cards generally target good-to-excellent credit (FICO 670+), with better approval odds in the 700+ range. Capital One also offers a Quicksilver One card for fair credit (FICO 580–669) with a lower credit limit. Citi Double Cash is primarily for established credit profiles. Neither issuer publishes a hard FICO cutoff; approval depends on income, credit history, and other factors. (Source: CFPB; citi.com; capitalone.com.)
Citi Double Cash requires a minimum of $1 (100 ThankYou points) to redeem as a statement credit, direct deposit, or check. Capital One Quicksilver has no minimum redemption threshold — you can redeem any amount as a statement credit, check, or through Capital One's shopping and travel portals, including applying rewards directly at checkout with Amazon. For infrequent redeemers who want to cash out small balances anytime, Quicksilver's no-minimum policy is more flexible. (Source: citi.com; capitalone.com.)
Neither card charges an annual fee. Both have historically offered cash welcome bonuses for new cardholders after a minimum spend in the first few months (verify current offers at citi.com and capitalone.com — amounts and thresholds change seasonally). Because neither has a fee to offset, the entire value comparison comes down to the 2% vs 1.5% earn-rate gap plus each issuer's redemption flexibility and ecosystem.
