How This Calculator Works

  • Enter your fleet size and average downtime hours per vehicle per month.
  • Enter the revenue a vehicle typically generates per hour of productive work.
  • Enter the fixed costs (driver wages, financing, insurance) that continue during downtime, per vehicle per day.
  • The calculator combines lost revenue and ongoing fixed costs into your true monthly and annual downtime cost.

Formula

Downtime Cost = (Downtime Hours × Revenue per Hour) + (Downtime Days × Fixed Cost per Day)

Fixed costs during downtime include things like driver wages, financing, and insurance that continue regardless of whether the vehicle is working.

Frequently Asked Questions

How do I estimate revenue per vehicle per hour?

Divide a vehicle's typical daily revenue (from freight, rental, or contract billing) by its typical working hours per day. For internal fleets without direct revenue, use an internal recovery or utility rate instead.

Why include fixed costs as well as lost revenue?

Because most fixed costs — driver wages, insurance, financing — don't pause just because a vehicle is in the workshop. Downtime cost is usually understated if only lost revenue is counted.

How does this connect to Fleet Availability and MTTR?

Reducing downtime hours — by improving Fleet Availability and Mean Time to Repair — directly reduces the cost this calculator estimates. See the related KPI guides below for how to improve both.
