How the calculation works

Estimate revenue affected by an empty truck

Other trucks may cover some calls while others go unserved during a technician vacancy. Your results separate total revenue at risk from the amount you expect to lose.

See the calculation

Daily revenue at risk

Multiply completed calls per day by average revenue per call to estimate daily revenue at risk. At 10 calls and $400 per call, the result is $4,000 per day, within the published HVAC peak-day range of $2,000 to $7,800.

Revenue lost during the vacancy

Multiply daily revenue by working vacancy days and the percentage of calls lost. The balance represents calls handled by other trucks.

Revenue and margin

This calculator estimates gross revenue. The workbook also calculates contribution margin after labor, parts, and other costs.
