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 BP
BP's Business Solutions cards offer volume-based rebates at BP stations, with the maximum earned at a comparatively low 10,000 gallons per month, plus card controls by day, week or month, fraud protection via ID and odometer prompts, and tracking of MPG and cost per mile. A Mastercard version fuels almost anywhere at reduced rebates.
WEX and BP 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. BP rebates reach up to 15 cents per gallon for customers buying 10,000-plus gallons monthly at BP stations, one of the more attainable volume thresholds among branded cards, with significantly lower rebates on the go-anywhere Mastercard route. 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. BP rewards station loyalty through volume rebates with a lower qualifying threshold than many rivals, so mid-size fleets can actually reach its headline rate. 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.
