HVAC Service Call Pricing Calculator

How can I include parts markup without charging for it twice?

Build the line-item price from non-parts cost, marked-up parts, and any customer trip charge. Compare that subtotal with the whole-job margin floor and quote the higher amount. Add an emergency surcharge once.

Worked example

With $120 of non-parts costs, $80 of parts, 25% parts markup, and a $40 trip charge, the line-item subtotal is $260. At a 25% target margin, the whole-job floor is $266.67, so quote $266.67 before an emergency surcharge.

How this calculator works

1. Choose the scope and enter your unit costs, crew or schedule assumptions.
2. Read the estimated costs and the result based on the inputs above.
3. Compare scenarios before copying or printing your estimate.

A trip charge is customer revenue. Enter vehicle expense separately as an actual cost. If after-hours payroll differs, model that cost before comparing the emergency surcharge.
