Break-Even Labor Hours Calculator for Contractors
Calculate how many billed labor hours your contracting business needs each month to cover overhead and break even.
Before You Start
To use this calculator accurately, you'll need to know your labor burden percentage and monthly overhead. If you haven't calculated your labor burden yet, use our labor burden calculator first—it will give you the percentage you need for this calculation.
What Are Break-Even Labor Hours?
Break-even labor hours are the minimum number of billed hours your contracting business must work each month to cover fixed overhead costs. Below this threshold, you lose money even if your crews are fully booked.
How they are calculated: Divide your monthly overhead by your contribution per sold hour (billed rate minus burdened labor cost). The result tells you exactly how many billable hours you need before you start generating profit.
Why a busy contractor can still lose money: If your contribution per sold hour is too low, even a fully booked crew cannot generate enough gross margin to cover overhead. High labor utilization with poor pricing or excessive labor burden creates cash flow problems that volume alone cannot fix. See our crew productivity calculator to measure true field output against your break-even targets.

Your billed labor rate does not cover burdened labor cost. Break-even is impossible until pricing rises or labor cost falls.
How Billed Labor Hours Needed to Cover Overhead Are Calculated
Burdened Labor Cost / hr
= Wage × (1 + Burden %)
Contribution / Sold Hour
= Billed Rate − Burdened Labor Cost
Break-Even Billed Hours
= Monthly Overhead ÷ Contribution / Sold Hour
Worked Example: Break-Even Hours for a Commercial Contractor
A commercial electrical contractor bills labor at $85/hour, pays field electricians $40/hour in wages, and carries a 30% labor burden (benefits, taxes, insurance). Monthly overhead (office rent, insurance, trucks, office staff) totals $48,000.
What this means operationally: This contractor needs to bill at least 1,455 hours per month (91% utilization) just to cover overhead. These are the contractor overhead hours required before any profit is generated. If the crew only bills 1,200 hours in a month, the business loses $8,250 before profit. To break even, they must either raise labor rates, reduce overhead, improve utilization, or add crew capacity.
Interpreting Your Results
Healthy Break-Even State
Required utilization below 80–85% and contribution per sold hour above $30–50. This means your labor pricing and overhead structure allow room for growth, unexpected slowdowns, and profit.
Action: Focus on sustaining utilization, improving crew productivity, and protecting your pricing discipline. Use our overhead recovery calculator to see how your overhead recovery rate aligns with these billed labor hour targets.
Over-Utilization / Unrealistic State
Required utilization exceeds 100%. Your current rates cannot cover overhead with available crew capacity. Even perfect utilization will not make you profitable.
Actions: Raise labor rates, reduce fixed overhead, add crew capacity, or shift non-billable work to lower-cost staff.
Impossible Contribution State
Contribution per sold hour is negative. Your billed labor rate does not even cover burdened labor cost. Every billed hour loses money before overhead.
Actions: Immediately raise labor rates or reduce labor burden (wages, benefits, or overhead load). This pricing structure cannot continue without catastrophic cash loss. Use our floor price calculator to determine the minimum viable rate you should charge.
Frequently Asked Questions
What are break-even labor hours?
Break-even labor hours are the minimum number of billed hours a contractor must work each month to cover fixed overhead costs. Below this level, the business loses money regardless of how efficiently crews work.
How do you calculate break-even labor hours?
Divide monthly overhead by contribution per sold hour (billed rate minus burdened labor cost). The result is the number of billed hours needed to cover overhead before generating profit.
What is a good utilization target for contractors?
Most contractors target 70–85% utilization of available productive hours. Below 70% suggests pricing or capacity issues. Above 90% leaves little room for emergencies, rework, or business development.
Why can a fully booked crew still lose money?
If contribution per sold hour is too low, even 100% utilization cannot generate enough gross margin to cover overhead. High volume with poor pricing or excessive labor burden creates cash flow problems.
Does break-even labor hours include overhead?
Yes. Break-even labor hours represent the billed hours needed to cover monthly overhead. Overhead is divided by contribution per sold hour to calculate the break-even threshold.
What happens if contribution per sold hour is negative?
A negative contribution means your billed labor rate does not cover burdened labor cost. Every billed hour loses money before overhead. This requires immediate rate increases or labor cost reductions.
How can I lower my break-even labor hours?
Raise your billed labor rate, reduce labor burden (benefits, taxes, insurance), lower fixed overhead costs, or improve crew utilization. Any of these actions increases contribution per sold hour or reduces the hours needed to break even.
