How Cents-Per-Gallon Rewards Work
Cents-per-gallon (CPG) rewards create a direct, tangible connection between customer behavior and fuel savings. The mechanic is simple: customers earn credits measured in cents, then redeem those credits as a per-gallon discount at the pump.
The Earning Phase
Customers accumulate CPG credits through various qualifying activities:
- Fuel purchases: Base earn on every gallon (e.g., 1 cent per gallon purchased)
- Inside-store spending: Credits for convenience store purchases (e.g., 5 cents per $25 spent)
- Promotional behaviors: Bonus credits for specific products, dayparts, or visit frequency
- Partner transactions: Coalition earn from grocery, dining, or other partner purchases
The Redemption Phase
When customers fuel up, accumulated credits apply as a per-gallon discount:
- Customer identifies at the pump (app, card, phone number, or linked payment)
- System displays available CPG balance
- Customer chooses to apply rewards (automatic or opt-in depending on program design)
- Discount applies per gallon up to the fill limit (typically 20-25 gallons)
- Reduced price displays on the pump and receipt
Common CPG Reward Structures
Threshold-Based Earning
Credits unlock after reaching spending thresholds.
Example: "Earn 10¢/gallon after spending $100 in-store this month"
Continuous Accumulation
Credits earn proportionally with every transaction, accumulating over time.
Example: "Earn 1¢/gallon for every $10 spent anywhere in-store"
Tiered Structures
Higher-tier members earn enhanced CPG rates.
Example: "Gold members earn 5¢/gallon on fuel; Platinum members earn 8¢/gallon"
Promotional Stacking
Base earn plus bonus offers for specific behaviors.
Example: "Base 3¢/gallon + bonus 10¢/gallon when you buy 2 energy drinks"
CPG Reward Best Practices
- 1. Connect fuel rewards to inside-store margin. CPG should drive cross-category purchases, not just fuel volume. The most effective structures reward inside-store spending with fuel savings.
- 2. Set appropriate fill limits. Caps (typically 20-25 gallons) prevent extreme redemptions on commercial vehicles while covering most consumer fill-ups.
- 3. Make rewards visible at the pump. Real-time display of available savings increases redemption and reinforces program value at the moment of decision.
- 4. Measure incrementality, not just redemption. High CPG redemption doesn't equal success if it's subsidizing customers who would have fueled anyway. Use incremental margin measurement.
- 5. Balance generosity with sustainability. CPG rewards must fund themselves through incremental margin. Overly generous structures erode profitability.
