Vehicle Cost-Per-Mile Calculator

Find the true cost of putting your truck or van on the road — fuel plus fixed and variable buckets — then a suggested per-mile billable rate and trip charge. No signup.

Driving

What you pay at the pump, per gallon.

Your real-world MPG — a loaded service van is often 14–20, not the window sticker.

Typical 12,000–15,000 mi/yr; this is the divisor for every fixed cost.

Annual costs

Variable — rises with miles driven.

Fixed.

Fixed. Enter 0 if owned outright.

Roughly (what you paid − resale) ÷ years owned. Leave the default if unsure.

Fixed.

Show billing options

Off = you drive (owner). On = add a per-mile driver wage as a variable cost.

Markup is added on your cost; 30% on a $0.58/mi cost ≈ $0.75/mi billable.

Round-trip miles for one job, to preview the travel charge.

True cost to put this vehicle on the road.

How this is calculated

Every cost is turned into $ per mile and added up. Fuel is fuel price ÷ MPG. Each annual cost (maintenance, insurance, payment, depreciation, registration) is divided by your annual miles. Costs are grouped variable (fuel, maintenance, driver pay — they rise with miles) versus fixed (insurance, payment, depreciation, registration — incurred whether you drive or not). 

fuel / mi      = fuel price / MPG
bucket / mi    = annual cost / annual miles
variable / mi  = fuel + maintenance + driver pay
fixed / mi     = insurance + payment + depreciation + registration
cost / mi      = variable + fixed
cost / 100 mi  = cost / mi × 100
annual cost    = cost / mi × annual miles
billable / mi  = cost / mi × (1 + markup%)
trip charge    = billable / mi × round-trip miles

The suggested billable rate uses markup on cost (cost × (1 + markup)), not the margin formula cost / (1 − margin). The IRS 2026 standard mileage rate (72.5¢/mi) is shown as a sanity-check benchmark only; it is not a figure this tool computes for you, and the printout is a planning worksheet, not a mileage log.
