How it works
Road Trip Budget Calculator: inputs, formula, and result
This calculator integrates total route distance, vehicle MPG, and anticipated gas prices to establish the baseline fuel cost for a road trip. It allows you to visualize what percentage of your total trip funds will be consumed at the pump.
Formula
Fuel Budget = (Trip Distance ÷ Vehicle MPG) × Fuel Price
Worked example
A 1,200-mile road trip at 30 MPG with gas at $3.50/gallon needs a fuel budget of (1200 ÷ 30) × 3.50 = $140.00.
Pro tip: Add 15-20% to your calculated fuel budget to cover detours, city driving at your destination, and fuel price variations along your route.
