Mobilization Trip Charge Calculator

Mobilization is where small jobs quietly lose money

A crew does not appear on-site for free. The company pays for driving, loading, unloading, trailer time, dispatch, fuel, and setup before the first productive hour happens. On a large job, that cost can hide inside the base price. On a small job or a remote job, it can wipe out the entire margin.

This calculator turns mobilization into a bid-ready charge. Enter the one-way miles, number of round trips, loaded truck cost, crew drive time, setup time, admin coordination, and target margin. The result is the minimum trip charge needed before the actual work is priced.

A worked example

A two-person crew drives 22 miles each way and expects two round trips. At $1.15 per loaded mile, mileage costs about $101. Drive time and setup add $432 of burdened labor. Trailer, dispatch, and an 8% fuel surcharge bring the cost before margin to about $665.

With a 25% target margin, the mobilization charge should be about $887. If the bid only carries a $650 trip charge, the job is short roughly $237 before the crew starts producing billable work.

How to use the number

For repeatable service work, turn the result into zones: local, outer market, and remote. For project work, keep the charge inside the estimate so markup and margin are calculated after mobilizing cost is included. Revisit the loaded mile cost whenever fuel, insurance, truck payments, or trailer costs change.
