Mechanic job margin calculator
Enter labour and parts to see a job's price ex GST, GST, total, cost and gross profit, plus margin and markup, which are often confused. All figures are calculated ex GST, because GST isn't income.
Early access: BayAutomate is onboarding Australian workshops now. Anything marked Coming soon or Planned isn't available yet. Everything else is included on every plan.
Sell ex GST = hours × rate + parts sell. Cost = hours × labour cost + parts cost. Profit = sell − cost. Margin = profit ÷ sell. Markup = profit ÷ cost. GST = 10% of sell.
Margin vs markup
Margin = profit ÷ sell price. Markup = profit ÷ cost. A part bought at $60 and sold at $100 has a 40% margin and a 66.7% markup.
Questions
Should margins include GST?
No. Work margins out ex GST, because GST is collected for the ATO.
