Custom Home Builder Break-Even Calculator
Know the exact revenue and the number of jobs your custom home business needs each month just to cover costs. Put in your overhead and average job, and see your break-even point by day, week, and month.
Built for custom home owners who'd rather know than guess. Your numbers stay in your browser.
Fixed costs are what you pay whether or not a job books — rent, insurance, vehicles, software, office and owner wages, ad retainers.
| Jobs to break even / month | 1 |
| Jobs / week | 1 |

Everything above break-even is profit. Drop your margin or average job and watch how many more jobs you need just to stand still.

See your break-even number
Exactly how much revenue and how many jobs you need each month before your custom home business makes a dollar of profit.
Know the activity it takes
Break-even turns into jobs per day and per week, so the target stops being abstract and starts being a schedule.

Nudge your average job or margin and watch the break-even point move. This one surprises most owners.
How it works
The math behind the number
Break-even revenue is your fixed monthly costs divided by your gross margin. Divide that by your average job value and you get the number of jobs you need before the business makes a dollar.

FAQ
Common questions

- Divide your fixed monthly costs by the gross profit on an average job (average job value × gross margin). That gives the number of jobs you need to cover costs; multiply by average job value for the revenue.
- What counts as a fixed cost?
- Rent, insurance, vehicle payments, software, owner and office wages, advertising retainers — anything you pay whether or not a job books. Materials and job labour are variable, captured by your margin.
