Compare the real monthly and annual savings of the WEX and Shell fuel cards on your fleet's gallons, after fees.

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 Shell
Shell offers two business fleet cards: a standard card for use at Shell stations and a Flex card accepted at about 95 percent of US stations with bonus savings when fueling at Shell. Features include online and mobile card controls, customizable purchase reports, enhanced purchase controls, driver training resources and 24/7 support, with no card fees on most options.
WEX and Shell 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. Shell's savings run up to 5 cents per gallon on the Shell Card Business Flex and around 6 cents on Shell Fleet Plus, earned primarily at Shell locations, with most of its card options carrying no monthly fees. 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. Shell is a station-branded card that rewards loyalty to Shell locations, with the Flex version adding broad acceptance at reduced rewards, so its value tracks how often your routes pass Shell stations. 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.
