About DriveCosts

DriveCosts was created because most online fuel and trip calculators are buried under ads, ask for sign-ups, or use the wrong units for US drivers. We wanted something we could pull up at the gas pump on a phone, get an answer in seconds, and trust the math behind it.

Every calculator on the site uses the standard US formulas — miles per gallon, dollars per gallon, dollars per kWh — and runs entirely in your browser. We don't store your inputs, we don't track your trips, and we never share data.

What you can do here

• Estimate fuel cost for any drive.
• Plan a road trip with per-passenger split.
• Measure your real MPG from fill-up data.
• See your true cost per mile including fixed costs.
• Calculate EV charging costs at home or on the road.

DriveCosts provides estimates only. Actual costs may vary based on vehicle condition, driving habits, gas prices, weather, terrain and local rates.
