Fixed costs divided by what a job really leaves behind - the number of jobs a month where the business stops costing you money.
Break-even is the most clarifying number a new business can know: the count of jobs, each month, where you stop losing money. Below it, every month eats savings. Above it, every additional job is mostly profit - because the fixed costs are already paid.
The math has one trap. Fixed costs do not divide by revenue; they divide by contribution - what a job leaves after its own materials, fuel, and helper hours. A $300 job with $60 of variable cost contributes $240, so $3,500 of fixed costs takes fifteen of them, not twelve.
The most common mistake is a break-even that skips the owner. If your fixed costs do not include your own pay, the business "breaks even" while you work for free. Put a real number for yourself in the fixed line - the point of the business is that it pays you.
If the answer says forty jobs a month and you can physically run twenty, the fix is price, not effort - the hourly rate calculator works out what those hours must bill. And when the monthly profit starts covering real life, the go full-time calculator tells you when the paycheck can go.
Fixed monthly costs divided by contribution per job, rounded up. A business with $3,500 of fixed costs whose average job leaves $240 after materials and fuel needs 15 jobs a month. The answer moves fastest when the job price moves, not the job count.
Job revenue minus the costs that job creates - materials, extra fuel, dump fees, helper hours. It is what the job actually hands the business. Dividing fixed costs by full revenue instead of contribution understates the jobs you need and is the classic break-even mistake.
Yes. A break-even that skips the owner means the business breaks even while you work for free. Put a real monthly number for yourself in fixed costs - the target is a business that pays you, then breaks even.
