# Cash Back Calculator

Calculate your credit card cash back rewards. See annual earnings, net rewards after fees, and break-even spending. Free cash back calculator.

## What this calculates

Calculate how much cash back you earn from your credit card spending. Enter your monthly spending, cash back rate, and annual fee to see your total rewards and whether a premium card pays for itself.

## Inputs

- **Monthly Spending** ($) — min 0 — Your average monthly spending on the card.
- **Cash Back Rate** (%) — min 0, max 10 — The average cash back percentage on your card.
- **Annual Fee** ($) — min 0 — The card's annual fee (enter 0 for no-fee cards).

## Outputs

- **Annual Cash Back** — formatted as currency — Total cash back rewards earned per year.
- **Net Rewards (after fee)** — formatted as currency — Cash back minus the annual fee.
- **Monthly Cash Back** — formatted as currency — Average cash back earned per month.
- **Break-Even Monthly Spending** — formatted as currency — Monthly spending needed to offset the annual fee.

## Details

Cash back credit cards return a percentage of your spending as a statement credit or direct deposit. The most common structures are flat-rate cards (1.5-2% on everything) and category cards (3-5% on rotating or fixed categories like groceries, dining, or gas, with 1% on everything else).

Whether a card with an annual fee is worth it depends on your spending. A card with 2% cash back and a $95 annual fee requires $4,750 in annual spending ($396/month) just to break even with a free 0% card. At $2,000/month spending, the 2% card earns $480/year minus $95 fee = $385 net -- compared to $360/year from a free 1.5% card. The premium card wins by $25, but only if your spending is high enough.

To maximize cash back, use category-specific cards for your highest spending areas (groceries, gas, dining) and a flat-rate card for everything else. Many people carry 2-3 cards to optimize rewards across categories. Just make sure to pay the full balance each month -- credit card interest rates of 20-25% will quickly erase any cash back earnings.

## Frequently Asked Questions

**Q: What is a good cash back rate?**

A: Flat-rate cash back cards typically offer 1.5-2% on all purchases. Category-specific rates range from 3-6% on targeted spending (groceries, dining, gas, streaming). A 2% flat-rate card is considered strong for a no-annual-fee option. Premium cards with annual fees may offer 3-5% in bonus categories. The best effective rate depends on your spending patterns.

**Q: Is a cash back card with an annual fee worth it?**

A: Calculate your expected annual cash back and subtract the fee. If the net is higher than what a free card would earn, the fee is justified. For example, a $95 annual fee card earning 2% needs about $6,334 in annual spending to beat a free 1.5% card ($6,334 x 0.5% = $31.67 extra, minus $95 = net loss until spending exceeds about $19,000). Do the math for your specific spending level.

**Q: How does cash back compare to travel rewards?**

A: Cash back is simple and flexible -- you get money back with no restrictions. Travel rewards can offer higher value (1.5-2 cents per point) but require using points for travel, dealing with blackout dates, and sometimes paying transfer fees. If you travel frequently and can maximize point values, travel rewards may be worth more. If you prefer simplicity, cash back wins.

**Q: Do I earn cash back if I carry a balance?**

A: Yes, you still earn cash back on purchases even if you carry a balance. However, the interest charges will far exceed your rewards. At 22% APR on a $2,000 balance, you pay about $37/month in interest but earn only $40/month in 2% cash back. After accounting for the principal portion of spending, carrying a balance makes cash back rewards pointless. Always pay in full.
