About this tool

Break-even revenue = monthly fixed costs ÷ gross margin — $12,000 ÷ 35% = $34,286 per month.

How to use

Enter monthly fixed costs, gross margin percent, and average job value — break-even revenue and jobs needed solve live.

How the math works

Fixed costs are everything that doesn't move with job volume: rent, insurance, salaries, trucks, office.

Gross margin is gross profit ÷ revenue — use your historical average, not your best month.

This is revenue planning; pair it with the Jobsite Breakeven tool for daily bid-floor rates.

Formula

BE = fixed costs ÷ margin

Common questions

▸How do you calculate break-even for a construction company?

Break-even revenue = monthly fixed costs / gross margin. With $12,000 in fixed costs and a 35% margin, you need $34,286 per month before the business profits.

▸How do I calculate my break-even revenue?

Divide monthly fixed costs by gross margin as a decimal - $12,000 / 0.35 = $34,286 per month. The calculator solves this live from your inputs.

▸What's the difference between markup and margin here?

Use margin (profit / revenue), not markup (profit / cost) - break-even is revenue-based, so margin is the right input. Mixing them up understates the revenue you need.

▸How many jobs do I need per month?

Break-even revenue / average job value - $34,286 / $8,500 is about 4 jobs per month. Enter your average ticket and the tool computes the job count for you.

▸What is a good profit margin for contractors?

10-20% net margin after overhead is a healthy target. Use your historical average gross margin, not your best month, so the break-even number stays realistic.
