Calculator guide
Calculate revenue needed to cover fixed overhead at your gross margin. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Break-even revenue = fixed costs ÷ contribution-margin fraction. A zero or negative contribution margin cannot cover fixed costs.
How to use this calculator
- Set Monthly fixed overhead ($). The interface starts with 18000; replace it with the value for your scenario.
- Set Average job price ($). The interface starts with 7500; replace it with the value for your scenario.
- Set Variable cost per job ($). The interface starts with 4800; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Monthly fixed overhead = 18000 $; Average job price = 7500 $; Variable cost per job = 4800 $. With those assumptions, the calculator gives Contribution per job: $2,700.00; Break-even jobs per month: 7; Break-even revenue: $52,500.00; Gross margin: 36%. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Contribution per job is $2,700.00. Break-even jobs per month is 7. Verify measurements, manufacturer coverage, packaging, local code, and site conditions. Quantity and budget estimates do not certify structural or electrical safety.
Limitations and assumptions
- Verify measurements, manufacturer coverage, packaging, local code, and site conditions. Quantity and budget estimates do not certify structural or electrical safety.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
Frequently asked questions
Which inputs should I check first?
