5 KPIs to Track Fuel Card Program Success
Monitor these metrics to ensure your fuel card program delivers maximum value:
Rebate Earned per Vehicle
Target: Increasing quarterly. Track total cents-per-gallon rebate across all cards; optimize program selection annually.
Fuel Cost per Mile
Target: Decreasing or stable. Integrate fuel data with CMMS for automatic cost-per-mile analysis.
Unauthorized Purchase Rate
Target: Below 0.5%. Monitor exceptions; tighten product codes and dollar limits to eliminate misuse.
Card Acceptance Coverage
Target: 95%+ of route locations. Verify network coverage quarterly; switch cards if acceptance gaps appear.
Administrative Time Savings
Target: 15+ hours/month. Automated data feeds eliminate manual reconciliation and receipt tracking.
Fuel Card Program Evaluation Pass/Fail Criteria
Rebate Rate
Pass: 8¢/gal or higher for bus fleet volumes. Tiered rebates that improve with volume.
Fail: Flat low rebate with no volume incentives; hidden fees that offset earnings.
Acceptance Network
Pass: 95%+ coverage of fleet routes. Includes truck stops, retail stations, and cardlock sites.
Fail: Limited network causing drivers to search for stations or use backup cards frequently.
Fraud Controls
Pass: Real-time alerts, purchase limits by gallons or dollars, product code restrictions, odometer prompts.
Fail: Basic controls only; no ability to restrict purchases to fuel and fleet-related products.
CMMS Integration
Pass: Automatic fuel data import into BusCMMS or similar platform for cost-per-mile tracking and PM scheduling.
Fail: No integration options; data remains siloed requiring manual entry.
Customer Support
Pass: 24/7 dedicated fleet support, online account management, and dedicated account representative.
Fail: General customer service with long hold times and no fleet-specific expertise.
Pricing Transparency
Pass: Clear fee structure with no hidden charges; all rebates and fees disclosed upfront.
