Compare the real monthly and annual savings of the WEX and TCS 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 TCS
TCS (TransConnect Services) targets truckers and owner operators with the highest average savings in our guide, alongside personalized account management, dashboard snapshots and a station finder app, available in the US and Canada. Its constraint is network size, with over 2,300 in-network stations, far fewer than the broad-acceptance cards.
WEX and TCS 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. TCS advertises average savings around 53 cents per gallon at in-network stations, the highest headline figure we track, typically with no signup cost; the trade-off is that the savings only exist where the network does. 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. TCS pairs the biggest headline discount in the guide with the smallest network, so it wins outright when your routes pass its stations and loses quickly when they do not. 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.
