How to Use This Calculator
Rewards Estimator tab
The default tab. Enter your monthly spending across six categories: groceries, dining, gas, travel, online shopping, and other. Select your card's reward structure (flat cashback, tiered categories, or points multipliers). The calculator shows your annual rewards in dollar value, broken down by category, plus your effective reward rate across all spending.
Annual Fee Break-Even tab
Enter your card's annual fee, its reward rate, and your monthly spending. The calculator shows exactly how much you need to spend to break even on the fee — both in absolute terms and compared to a no-fee card alternative. Expand "More options" to add a sign-up bonus for the first-year comparison.
Points Valuation tab
Enter your points balance and select your rewards program. The calculator shows your points' dollar value across three redemption methods: cash, travel portal, and transfer partners. See which method gives you the best value, plus a projection of your annual earning value.

The Formula
Credit card rewards are calculated based on your spending and the card's reward structure:
Break-Even Spending = Annual Fee / (Fee Card Rate - No-Fee Card Rate)
Points Value = Points Balance × Cents Per Point / 100
Effective Reward Rate = Annual Rewards / Annual Spending × 100
For flat cashback cards, every dollar earns the same rate (typically 1-2%). For tiered cards, bonus categories (groceries, dining, gas) earn 3-6% while other purchases earn 1%. For points cards, the value depends on how you redeem — cash is usually worth less than travel or transfer redemptions.
The break-even calculation compares the marginal benefit of the fee card's higher rate against what you would earn with a no-fee alternative. Premium cards often include non-reward benefits (lounge access, travel credits, insurance) that this formula does not capture.
Example
Maria — remote worker, Denver CO
Maria spends $3,200/month on her credit card. She is comparing a mid-tier card with a $250 annual fee (3% dining/travel, 1.5% everything else) against a no-fee card earning a flat 1.5%.
Monthly Spending Breakdown
Mid-tier fee card (3% dining/travel, 1.5% other, $250 fee)
No-fee card (1.5% flat)
The no-fee card wins by $106/yr ($576 vs $470 net). Maria would need to spend significantly more on dining and travel to justify the fee card's $250 annual cost. However, if the fee card includes a $300 travel credit, it becomes the better choice by $194/yr.
