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

About Coast
Coast is a modern fleet and fuel card built on the Visa network, so it works at any station that takes Visa with no network to plan routes around. It requires no personal guarantee, charges no per-transaction fees in the US, and its app lets owners set spending policies by driver, vehicle, day or merchant category with real-time alerts, plus 1 percent back on non-fuel business purchases.
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.
Coast and RTS pricing
Coast costs $4 per active user per month with no inactive card fees. Fuel savings of 3 to 9 cents per gallon are applied on your statement at any gas retailer, alongside 1 percent back on non-fuel spend, so the discount travels with you rather than depending on an in-network station. 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
Coast's pitch is simplicity: one flat discount that works at every Visa-accepting station, modern software controls and no personal guarantee, rather than a station network you have to fuel inside to earn the headline rate. 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.
