Compare the real monthly and annual savings of the WEX and RTS 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 RTS
RTS offers one of the industry's larger discounts through a network of about 3,500 stations tied closely to Pilot Flying J, Speedway, Circle K, Caseys and others, with broader coverage than the Pilot card alone. Its standout feature is a weekly line of credit per truck, a real cash flow cushion when customers pay slowly, with no contract or annual fees.
WEX and RTS 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. RTS advertises average savings around 25 cents per gallon at in-network stations with no contract or annual fees, and adds extra savings at some locations; the weekly per-truck credit line is part of the value beyond the rebate itself. 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. RTS combines high in-network discounts with weekly credit lines per truck, so it competes on cash flow as much as on cents per gallon. 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.
