How the optimizer works
Most credit card comparison sites show you one card at a time. But your wallet can hold 3 cards — and using the right combination can earn you hundreds of dollars more per year than any single card.
This optimizer models every combination of 1, 2, or 3 Singapore credit cards from our database. For each combination, it assigns each spend category to the card that earns the most cashback or miles — respecting per-category caps, monthly overall caps, and minimum spend thresholds.
Annual fees are deducted from gross rewards to give you a true net annual benefit. Waivable fees are treated as $0 (assuming you meet the spend threshold).

Frequently asked questions
What is the best credit card combo for everyday spending in Singapore?
The best 2-card combo for most Singaporeans is typically a strong category card (like OCBC 365 for dining/groceries or UOB YOLO for dining/online) paired with a flat-rate card (like SC Simply Cash at 1.5%) for everything else. The right combo depends heavily on your spend mix — someone who spends heavily on petrol should include UOB One or DBS Live Fresh; a heavy online shopper benefits from UOB YOLO or DBS Live Fresh.
Is it worth having 2 or 3 credit cards in Singapore?
For most Singaporeans, a 2-card combo outperforms a single card by $200–$600/year. The reason: no single card is best at everything. Category cards earn 5–8% on specific spend types but drop to 0.3–0.5% on others. A flat-rate card plugs those gaps. A third card adds diminishing returns and complexity — only worthwhile if you have large spend in a category your first two cards miss.
How are credit card annual fees factored in?
This calculator shows net annual benefit after annual fees. Most Singapore cards charge S$180–$260/year, but many waive the fee in the first year or with a minimum annual spend. Where a fee is waivable, we treat it as $0 — meaning the comparison assumes you meet the waiver threshold. For non-waivable cards (like DBS Altitude), the fee is always deducted from your gross cashback or miles value.
Why do some high-rate cards not appear in the top combo?
A card like Citi Cashback offers 8% on petrol, dining, and groceries — but each category is capped at $25/month ($300/year total). If you spend $600/month on dining alone, the cap means you only earn $300 from that card on dining per year, versus $432 from OCBC 365 (6% × $600 × 12, under the $80/month cap). The optimizer accounts for all caps, so high-rate but heavily-capped cards often lose to lower-rate but uncapped alternatives at higher spend levels.
When should I choose miles over cashback cards?
Miles cards only beat cashback when you can redeem miles at high value — typically $0.020–$0.040 per mile in SIA Business or First class. At economy redemption rates ($0.012–$0.018/mile), a good cashback card often wins. The breakeven: UOB PRVI Miles at 1.4 mpd × $0.018 per mile = 2.52% effective cashback — competitive with a flat 1.5% card but loses to category cards at their bonus rates. Choose miles if you regularly fly SIA business class.
