About WEX
The WEX Fleet Card is the most widely accepted fleet card in the United States, working at roughly 95 percent of fuel stations plus tens of thousands of service locations. Its strengths are universal acceptance, detailed purchase controls with driver IDs, automatic accounting data on every transaction, tax exemption reporting and access to the WEX EDGE savings network that also discounts tires, hotels and other business costs.
About EFS
EFS (Electronic Funds Source) is a trucking-focused card family: the Fleet One EDGE card for companies up to about 50 trucks with tire discounts and no fuel transaction fees, the EFS Fleet Card for larger fleets with real-time purchase limits and point-of-sale prompts, and an EFS Mastercard for anywhere-acceptance. It captures odometer and unit data and can match purchases against truck telemetry for security, across 12,000-plus locations.
WEX and EFS pricing
WEX pricing is quote-driven, with independent reviews commonly reporting around $4 per card per month for the core Fleet Card. Rebates run 3 to 15 cents per gallon inside the WEX EDGE savings network and 1 to 3 cents elsewhere, with the top rates tied to fueling location and monthly volume; the truck-stop oriented Fleet Cross Roads card averages around 15 cents in-network. EFS savings reach around 15 cents per gallon depending on location and program, concentrated at in-network truck stops, with fee structures varying by card and account; small monthly per-card fees are common on quoted programs. The calculator applies each card's discount to your monthly gallons, subtracts card fees, and compares net savings and effective price per gallon at the current diesel price.
How they compare
WEX's core strength is acceptance breadth: its discounts are modest outside the EDGE network, but the card works nearly everywhere, so its savings are dependable rather than spectacular. EFS is a truck-stop network card with unusually deep data capture, built for OTR diesel fleets, so it trades everywhere-acceptance for bigger in-network diesel discounts and security features. The honest comparison is a blended one: estimate what share of your gallons would actually earn each card's in-network rate on your real routes, set the discounts accordingly, and let the annual difference decide.
