Road Trip Cost Splitter
Plan a fair cost split before hitting the road. Enter the total distance, vehicle efficiency, and fuel price, then add tolls, lodging, and shared extras to see the full bill, cost per mile, and what each traveller owes.
Estimates assume constant MPG and prices. Adjust inputs for significant elevation changes, towing, or seasonal price swings.
Examples
- 1,250 miles at 26 mpg, $3.85/gal, 3 travellers, $120 tolls, $780 lodging, $450 extras ⇒ Fuel $185.10, tolls $120.00, lodging $780.00, extras $450.00 ⇒ Total $1,535.10, split $511.70 each, $1.23 per mile.
- 850 miles at 32 mpg, $3.40/gal, travellers blank (defaults to 2), $0 tolls, $520 lodging, $300 extras ⇒ Total $1,213.75, split $606.88 each, $1.43 per mile.
FAQ
How do I handle different spending by traveller?
Use this tool for the core shared costs, then track individual extras separately (e.g., snacks, souvenirs) with a shared spreadsheet or expense app.
Can I include currency conversions?
Convert foreign expenses into USD before entry using your expected exchange rate so the totals reflect a single currency.
What if we drive two vehicles?
Run the calculator for each vehicle separately, then add the totals and divide by the combined traveller count to keep the split proportional to actual fuel consumption.
Additional Information
- Fuel cost equals distance divided by MPG multiplied by the weighted average price per gallon.
- Shared extras can include groceries, parking, rideshares, or attraction passes paid from a group kitty.
- Cost per mile helps compare the trip to reimbursement rates or alternative transport modes.
