What You Need to Know
💡Why This Calculator Matters
Cash back rewards add up to hundreds or thousands per year. Optimizing your card strategy maximizes returns on spending you'd do anyway.
👤Who Needs This
Anyone using credit cards, people choosing between cards, or those wondering if rewards cards are worth annual fees.
🎯Key Insight
Category-specific cards (5% groceries, 5% gas) often beat flat-rate cards if you can manage multiple cards. But 2% on everything is simpler and still excellent.
⚠️Common Mistake
Carrying a balance to earn rewards. Even 3% cash back is crushed by 20%+ interest. Only use rewards cards if paying in full monthly.
✅Pro Tip
Pair a flat 2% card for everyday spending with category cards for your biggest expenses. Many people earn $1,000+/year this way.
📊Real-World Example
Scenario: $50,000 annual credit card spending
2% flat cash back = $1,000. Or: 5% on $6,000 groceries + 3% on $15,000 dining + 2% on $29,000 other
Optimized strategy: $300 + $450 + $580 = $1,330. Worth $330 extra for managing 2-3 cards.
