What Is Cashback and How Does It Work?
Cashback is a rebate on eligible spending, credited back to your account as a statement credit, direct deposit, or gift card. It’s processed when purchases post to your account, not instantly at the point of sale.
- Statement credit reduces your balance
- Direct deposit sends cash to your bank (e.g., via ACH in the US)
- Gift cards or merchandise credits (some issuers)

How Cashback Credit Cards calculate Rewards: Core Cashback Calculation Methods
Below are the four primary ways issuers calculate cashback. Choose a method that aligns with your spending profile.
| Method | How It Works | Example Calculation | Best For | Complexity |
|---|---|---|---|---|
| Flat-Rate | Uniform rate on all purchases (e.g., 1.5%–2%). | $1,000 × 2% = $20 | Varied spending, simplicity seekers | Low |
| Category-Based | Higher rates (3%–6%) in select categories; lower base rate elsewhere. | $500 groceries × 5% + $500 other × 1% = $30 | Heavy spenders in key categories | Medium |
| Tiered | Rates increase as you cross spending thresholds (e.g., 1% up to $2K, 2.5% above). | $3K at 1% + $2K at 2.5% = $60 on $5K | High-volume spenders | Medium |
| Rotating Categories | 5% back in quarterly categories (gas, groceries, online); requires activation; caps apply. | Q1 gas $1,000 × 5% = $50 | Strategic planners, seasonal shoppers | High |

Key Factors Influencing Cashback
- Eligible vs. Ineligible Transactions
Cash advances, balance transfers, gambling, and some utility or tax payments often earn no cashback. Always check your card’s terms. - Merchant Category Codes (MCCs)
Four-digit MCCs assigned by card networks determine category classification. For example, Walmart’s grocery department (MCC 5411) versus general merchandise (MCC 5399) can affect your rate. Learn more from Investopedia. - Spending Caps & Limits
Monthly, quarterly, or annual caps cap your bonus-rate earnings. A 5% grocery card might cap at $1,500 per quarter (max $75 cashback). - Redemption Minimums & Frequency
Some issuers require a $25 minimum before redemption; others allow any accrued amount. - Annual Fees vs. Break-Even

Advanced Considerations & Pro Tips
- Promotional Launch Bonuses: Introductory 10% back on $1,500 spend can supercharge first-year returns—then revert to standard rates.
- Stacking Offers: Combine issuer portals (e.g., Chase Ultimate Rewards) with purchase-level promos for extra savings.
- No Foreign Transaction Fee Cards: Essential for travellers; otherwise 3% fees can nullify your earnings.
Common Mistakes & How to Avoid Them
- Carrying a Balance: Interest rates (18–29%) quickly outweigh cashback benefits—always pay in full.
- Chasing Rates: High rates don’t matter if caps or fees wipe out gains.
- Overspending: Only spend what you would normally; don’t buy extras just to earn rewards.
Overspending for Rewards
Never spend money unnecessarily just to earn cashback. The best rewards strategy involves earning cashback on spending you would do anyway.
