About

Credit card cashback programs vary from flat-rate structures at 1 - 2% to tiered systems offering 5% on rotating categories but 1% on everything else. The difference between choosing the wrong card and the right one can exceed $300 per year for a household spending $4,000 monthly. Most consumers ignore the annual fee offset: a card charging $95 annually needs at least $9,500 in spending at 1% just to break even. This calculator computes net cashback across up to six spending categories, subtracts annual fees, and reports your effective reward rate r_eff so you can compare cards on equal footing.

Assumptions: cashback is uncapped per category, redeemed at face value (no point devaluation), and spending is consistent month-to-month. Promotional intro rates are excluded. If your card imposes quarterly caps (common on 5% rotating categories at $1,500 per quarter), manually reduce the category amount to the capped figure for an accurate result.

Formulas

Total cashback earned across n spending categories:

C_total = n∑i=1 S_i × r_i100

Net annual cashback after the annual fee F:

C_net = C_total × 12 − F

Effective cashback rate across all spending:

r_eff = C_netS_total × 12 × 100

Break-even monthly spend (minimum to offset the annual fee):

S_break = Fr_avg × 12

Where: S_i = monthly spend in category i. r_i = cashback rate for category i in %. F = card annual fee in $. r_avg = weighted average cashback rate across all categories. S_total = sum of all monthly category spending.

Frequently Asked Questions

The annual fee is subtracted from your total annual cashback earnings before computing the effective rate. A card with 2% flat cashback and a $95 annual fee yields an effective rate below 2%. For example, on $2,000/month total spend, gross cashback is $480/year, but net is $385, dropping the effective rate to approximately 1.60%. The lower your total spend, the more the fee erodes your rate.

Break-even spend is the minimum annual expenditure at which your cashback earnings exactly equal the card's annual fee, yielding $0 net benefit. It equals F ÷ r_avg. If your actual spend falls below this threshold, you lose money by holding the card. A $95 fee card at 2% requires $4,750/year ($396/month) just to break even.

It depends on spending concentration. If over 40% of your monthly spend falls into one bonus category (e.g., groceries at 3 - 5%), a tiered card typically wins. If spending is evenly distributed across many categories, a 2% flat-rate card usually produces higher net returns. Use the comparison mode to test both scenarios with your actual numbers.

Many rotating-category cards cap bonus earnings at $1,500 in purchases per quarter. Spending above the cap earns only the base rate (typically 1%). To model this accurately, enter the capped amount as your category spend. For example, if you spend $800/month on groceries but the cap is $500/month equivalent, enter $500 at the bonus rate and $300 under a separate row at the base rate.

No. Sign-up bonuses are one-time events that distort ongoing cashback analysis. A $200 sign-up bonus amortized over 5 years adds only $40/year. This tool focuses on steady-state annual returns to help you pick the best card for long-term use.

Common discrepancies: merchant category codes (MCC) may classify a purchase differently than expected (e.g., a warehouse club coded as wholesale, not grocery). Returns and refunds reduce the base spend. Some issuers exclude specific transaction types (cash advances, balance transfers, fees) from rewards. This calculator assumes all entered spending qualifies for the stated rate.
