What this result does not account for
- Miles and US gallons — the converters own metric translation
- Distance 0 to 50,000; MPG 1 to 200; prices and fees 0 to 10,000
In short: 1,200 miles at 28 MPG and $3.50 burns $150.00 of fuel; tolls and parking add $68 — the trip costs $218.00, 18.2¢ a mile, and four people split it at $54.50. The fuel page prices the pump line alone; this page assembles the drive.
Formula
fuel = miles ÷ MPG × price; total = fuel + tolls + parking; per person = total ÷ passengers
A trip's true cost is the pump line plus everything the road charges on top: the tolls you roll through and the parking you land in. The fuel line is the mileage page's arithmetic — distance over your real MPG, times today's price. The cents-per-mile figure is the comparand that survives the trip: price any distance, any car, on one line. The split divides the WHOLE trip, not just the fuel — the tolls and parking are shared road costs too.
Worked Example
- Enter the distance, your MPG and the pump price.
- Add the trip's tolls and parking.
- Read the total, the cents per mile, and the split.
Defaults: 1,200 miles at 28 MPG and $3.50, $28.00 tolls, $40.00 parking — $218.00 total, 18.2¢ a mile, $54.50 a person at four.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Trip Cost Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How is this different from the fuel page?
The fuel cost page prices the pump line alone — gallons times price. This page assembles the WHOLE drive: fuel plus the tolls and parking the road charges on top, which on a city trip can be a third of the total.
Where do I get an honest MPG?
From the gas mileage page — two full fill-ups and the gallons between them. The dash average runs optimistic, and the MPG you feed here decides the answer.
Do the tolls include the drive home?
Enter whatever the WHOLE trip pays: double the one-way crossings, or the round trip's distance. The page prices what you enter, so a round trip is one doubled entry away.
Why cents per mile?
Because it is the number that compares across trips: 18.2¢ a mile prices this car on this route, and any other distance multiplies straight from it.
Does the split cover everything?
It divides the fuel, tolls and parking by the passengers — the road costs of the car. Meals and lodging are separate lines; add them into tolls if the car is settling up in full and the arithmetic stays honest.
What about wear on the car?
Deliberately out of scope here: the depreciation page prices what the miles cost the CAR itself, and it is usually the biggest per-mile line you never see at the pump.
Can tolls be zero?
Yes — a toll-free run reads the fuel line as the whole story, and the extras card says so plainly instead of pretending the road was free but priced.
Is this a tax deduction?
No — it is what the drive costs in cash. What an employer or the tax code REPLIES for those miles is the reimbursement page's question, and the two rarely agree.
