Maximizing Credit Card Cash Back
Cards with bonus categories can yield $500+/year. A card is worth its annual fee if net rewards exceed a no-fee card.
How to Use This Cash Back Calculator
Enter your monthly spending by category (groceries, gas, dining, travel, other) and the cash-back rate for each category. The calculator shows your annual rewards.
Formula & How It Works
Annual Cash Back = Ξ£ (Monthly Spending Γ Category Rate Γ 12). Effective rate = Total Cash Back / Total Annual Spending Γ 100%.
Calculation Example
Spending $600/mo groceries (3%), $200 gas (3%), $400 dining (2%), $1,000 other (1%): Annual cash back = ($18+$6+$8+$10) Γ 12 = $504/year (2.1% effective).
Expert Tips
Pair a flat-rate card (1.5-2%) for general spending with a category bonus card for groceries and dining. Always pay the full balance β interest charges far exceed any cash-back rewards.
