General Contractor Break Even — Frequently Asked Questions

Most independent general contractors need only 4—8 jobs per month to break even, because average project values ($15,000—$35,000) are significantly larger than other trades. However, each project carries higher variable costs — materials, subcontractors, and equipment — so the contribution margin per job needs to be carefully managed. A single large project going over budget can eliminate an entire month of profit.
Variable costs for a GC job include all direct project expenses: materials purchased for that specific job, subcontractor payments, equipment rental, permit fees, and job-site consumables. These costs only occur when you do the job. Fixed costs — insurance, vehicle payments, office overhead — remain the same regardless. The difference between job value and variable costs is your contribution toward covering those fixed costs and generating profit.
General contractors typically need fewer jobs to break even because each project generates significantly more revenue than a plumber's service call or a landscaper's maintenance visit. A single $25,000 project can generate $16,250 in contribution margin (after 35% variable costs), which can cover most of a solo GC's fixed costs for the month. The trade-off is that projects take longer, cash flow is less predictable, and cost overruns hit harder.
Cash flow management is one of the biggest challenges for GCs. Best practices include: collecting a substantial deposit (25—33%) before starting work, billing progress payments at defined milestones rather than waiting until completion, keeping a cash reserve of at least two months' fixed costs, and staggering project start dates so you always have at least one active job generating cash. Your break-even calculation shows exactly how much revenue you need each month to stay solvent.
GCs can lower their break-even point by increasing average job value (pursuing larger projects), reducing variable costs through better subcontractor negotiation and materials buying, or cutting fixed overhead. The most powerful lever is increasing contribution margin — if you can raise your average project from $25,000 to $35,000 while keeping variable costs proportional, your fixed costs become a smaller percentage of revenue and you need fewer projects to cover them.
