Cashback Glossary
Definitions for cashback-and-shopping-portal terminology — how portals compete on stacked rates, why payout thresholds matter, and the difference between static and rotating category rewards on cashback credit cards.
- Boosted rate
-
A time-limited elevated cashback percentage on a specific retailer or category, run by a portal or credit-card issuer. Boosted rates typically run 24–72 hours and require activation.
Why it matters: Stacking a portal boost with a credit-card category bonus and a retailer coupon is the highest-ROI configuration of the cashback stack.
Example: Rakuten regularly runs boosted rates (e.g., 10% at major retailers) during holiday windows.
- Browser extension (cashback)
-
A portal's browser plugin that auto-detects supported retailers, prompts for portal activation at checkout, and applies coupons. Most major portals offer extensions.
Why it matters: The extension eliminates the most common cashback failure mode (forgetting the portal click). Trade-off: portal extensions have privacy and browser-performance implications.
- Cashback portal
-
A third-party service (Rakuten, TopCashback, BeFrugal, Capital One Shopping) that earns affiliate commissions from retailers and shares part of the commission back to the shopper. The portal must be clicked through before the purchase for tracking to work.
Why it matters: A 5% portal bonus on top of a 2% credit card is effectively 7% back. Forgetting the portal click leaves the 5% on the table.
- Coupon stacking
-
Applying a retailer coupon code at checkout alongside (not instead of) the cashback portal click. Some portals disallow stacking with coupons not surfaced through the portal — read the portal's terms.
Why it matters: Stacking the wrong coupon can void portal tracking and cancel the cashback. Use portal-surfaced coupons or confirm portal tracking after the purchase.
- Effective rate
-
The actual cashback percentage after stacking portal + credit-card + coupon + receipt-scanning + boosted promotions, divided by the original purchase price. The most honest single number for comparing cashback strategies.
Why it matters: Headline cashback percentages mislead. Effective rate is what shows up in your bank account after the full stack settles.
Example: BB cashback stacking guide computes effective rates on representative retailer baskets.
- Exclusion (cashback)
-
A merchant category or product type that does not earn cashback regardless of how purchased (e.g., gift cards at most portals; some pharmacy items; alcohol in restricted states; tax-related services).
Why it matters: A purchase that looks eligible may not be. Read the merchant-specific terms before counting on a portal bonus.
Example: Most BB cashback reviews enumerate the major exclusions per portal.
- Holding period (cashback)
-
The time between a tracked purchase and when the cashback becomes "available" (eligible for payout). Holding periods range from a few days (Capital One Shopping) to 60–90 days (Rakuten for some retailers).
Why it matters: Returns within the holding period reverse the cashback. The holding period is a soft commitment to keep the purchase.
Example: Most BB cashback reviews note the holding period because it determines time-to-cash for the bonus.
- Payout threshold
-
The minimum balance required before a portal will release cashback to a check, PayPal, or bank account. Common thresholds: $5 (Rakuten), $10 (TopCashback), $5 (Ibotta).
Why it matters: A portal with a high threshold ties up your earnings until you accumulate enough. Most portals also have a holding period before earnings become eligible for payout.
- Receipt scanning
-
A category of apps (Ibotta, Fetch Rewards) that pay rewards for uploaded purchase receipts, often with rebate offers on specific products. Rewards are independent of how the purchase was paid for and stack with portal and credit-card rewards.
Why it matters: Receipt scanning is the third layer in the cashback stack. It adds friction (per-purchase scanning) but produces 1–5% additional back on eligible items.
Example: Ibotta is a BB-tracked receipt-scanning app with a signup bonus on first qualifying receipt.
- Referral bonus (cashback)
-
A reward paid to an existing user (and sometimes to the new user) when a referred user signs up and meets the activation requirement. Common: $10 to referrer + $10 to referee after first qualifying purchase.
Why it matters: Cashback portal referral structures are the friendliest in the industry — the referee typically earns the same welcome bonus they would earn organically, plus the referrer earns separately.
Example: Rakuten, TopCashback, and most BB-tracked cashback portals run referral programs.
- Reset window
-
For rotating-category credit cards, the date on which the new quarterly category becomes active. Cards may also reset annual category caps (e.g., the $1,500 quarterly cap on Discover it).
Why it matters: Knowing the reset date lets you front-load spend in the new category and avoid wasting spend on the expiring one. Calendar the resets.
Example: Discover it Cash Back resets quarterly; each new 5% category requires activation.
- Stack
-
Combining multiple rebate or reward sources on the same purchase — typically portal + credit-card category bonus + retailer-specific coupon + receipt-scanning app. Each layer adds a few percentage points to the effective discount.
Why it matters: A well-stacked $100 purchase can produce 10–15% back versus 2% on a flat-rate card alone. Stacking is the entire value proposition of the cashback vertical.
Example: BB cashback stacking guide demonstrates portal + credit-card + Ibotta stacks on common retailers.
- Static vs. rotating categories
-
A cashback credit card with static categories pays a fixed bonus rate on the same merchant types year-round (e.g., 3% on dining). A rotating-category card changes the 5% bonus category quarterly, sometimes requiring activation.
Why it matters: Rotating cards usually have higher peak rates but require quarterly activation and category planning. Static cards are simpler but lower-ceiling.
- Tracking failure
-
A case where a portal click did not register and the cashback does not post. Causes include ad-blockers, expired cookies, multiple portal clicks before checkout, and retailer-specific tracking issues.
Why it matters: Tracking failures are the single largest source of cashback complaints. Most portals have a missing-cashback claim form, but resolution is not guaranteed.
Example: Every BB cashback review notes the operator's missing-cashback claim window and resolution path.
- Welcome bonus (portal)
-
A one-time bonus credited after the first qualifying purchase routed through the portal. Common: $10 portal bonus after $25 in qualifying purchases.
Why it matters: Welcome bonuses make trial cheap. Stack a $10 portal welcome bonus with the first organic purchase you would make anyway.
