Vehicle Downtime Cost Calculator
Put a real number on a vehicle being off the road — the cost of one event and what it adds up to across a year.
Cost of downtime
Event cost is lost revenue (revenue per hour × hours) plus the fixed daily cost prorated over the days down (hours ÷ 24). The annual figure multiplies that by how many similar events you expect in a year. Losses shrink if a spare vehicle can cover the route.
Downtime is a cost, even when the workshop is idle
Every hour a coach sits waiting for a part or a bay is an hour it isn’t earning, while its finance, insurance, and depreciation carry on regardless. This calculator brings those two together — the fares lost and the fixed costs that keep accruing — into a single cost per event, then scales it to a year so you can see the true exposure from a recurring fault.
Seeing that annual figure often makes the case for holding a critical spare, tightening preventive maintenance, or arranging cover before it is needed, rather than after a vehicle is already stranded.
Frequently Asked Questions
How is the cost of a downtime event calculated?
It adds the revenue you lose while the vehicle is off the road — revenue per hour times the downtime hours — to the fixed costs that still accrue by the day, prorated over the days it is down (hours divided by 24). An 8-hour stoppage at $65/hour with a $140/day fixed cost works out to about $560 for the event.
What counts as a fixed daily cost?
Costs that keep running whether the vehicle earns or not — finance or lease payments, insurance, depreciation, and licensing spread over the year. Entering a daily figure captures the fact that an idle vehicle is still costing money on top of the fares it isn't earning.
How does the annual figure work?
The tool multiplies the cost of one event by the number of similar events you expect in a year. If a certain type of breakdown tends to happen roughly once a month, twelve events give a realistic annual exposure you can weigh against the cost of preventing them.
Why does downtime cost more than just the repair bill?
The parts and labour are only part of it. A vehicle off the road can mean cancelled duties, lost fares, hired-in cover, disappointed passengers, and fixed costs ticking away — often several times the invoice for the repair itself. Sizing that helps justify spares holding and preventive maintenance.
What if a spare vehicle covers the route?
Then the lost-revenue portion shrinks or disappears, because the service still runs. In that case set the revenue per hour low or to zero and let the fixed daily cost and any hire cost represent the real impact. The calculator is a framework — tailor the inputs to how your operation actually absorbs a stoppage.
