Before a long weekend drive someone always asks "about how much gas money." You have trip miles, the car's MPG habit, and the station price on the sign. The form estimates gallons needed and multiplies by price—enough for a shared spreadsheet row, not a fleet audit with tolls and tire wear.
Traffic, AC, roof racks, and "mostly highway" lies change real consumption. Treat MPG as the number you actually average, not the sticker from when the car was new.
Fuel cost for 240 miles at 30 MPG and $3.75 per gallon uses the defaults—still compared against "maybe thirty bucks?" in chat.
Miles, MPG, and the pump price
If distance came from speed and time, run that first—45 mph for 2.5 hours—then paste miles here. Kilometers on the odometer need conversion—400 kilometers in miles—before MPG math in miles per gallon.
Sharing cost per person is division outside this page; the page stops at total fuel dollars. Compare pump prices mentally; this form does not hunt coupons.
- U.S.-style miles and gallons in the labels shown.
- Round-trip means miles there and back unless you already summed.
- Estimate for budgeting, not tax reimbursement without receipts.
The gas cost trip estimate note fits road-trip threads. Planning math only.
