Electrical Contractor Break-Even Calculator

Estimate the annual, monthly and weekly revenue your electrical business needs to cover overhead — and, optionally, the revenue required to reach a profit goal.

Break-even revenue is the sales level where the contribution generated by the company's work covers the modeled operating overhead. It is not the same as cash-flow break-even, and it does not automatically include desired profit — profit is an optional, separate calculation here.

The calculator runs entirely on your own overhead and contribution-margin assumptions. There are no industry averages behind it and no recommended margin. Learn how electrical business break-even works.

Run the numbers

Your Assumptions

Use the annual company overhead you want the business to recover. Need help calculating overhead?

Enter the percentage of revenue remaining after the direct/variable job costs included in your model. This percentage contributes toward overhead and then profit.

Used only to calculate a rough break-even revenue per billable field employee.

Leave blank or enter $0 to calculate pure break-even. Enter a profit-dollar target to estimate the revenue needed to cover overhead plus that modeled profit target.

Your results

Enter your annual overhead, contribution margin and field headcount, then select Calculate Break-Even.

What Is Break-Even Revenue?

Break-even revenue is the modeled sales floor: the point where revenue minus direct job costs minus operating overhead is approximately zero. Below it, the company is not generating enough contribution to pay for itself; above it, each additional revenue dollar contributes its margin share to operating profit.

How Contribution Margin Affects Break-Even

Contribution margin is the divisor in the formula, so small changes move the required revenue sharply. Holding overhead at $300,000: a 40% margin breaks even at $750,000, a 30% margin needs $1,000,000, and a 50% margin needs $600,000. Lower margin means each dollar of sales contributes less toward overhead, so more revenue is required.

Contribution margin is produced by pricing. If percentages are the sticking point, markup vs margin for electrical contractors explains the difference, and the markup vs margin calculator converts between them.

Why Overhead Matters

Overhead is the numerator — it sets the height of the floor. Vehicles, insurance, office and administrative payroll, software, marketing and licensing all raise the contribution dollars the company must produce before anything is left over. An incomplete or out-of-date overhead total produces an optimistic break-even figure.

How to calculate electrical business overhead covers what belongs in the number, and the overhead calculator totals it by category.

Break-Even vs Profit Goal Revenue

Break-even covers modeled overhead and stops there — no owner profit, no reserve, no cushion. Profit-goal revenue adds a desired operating profit to the numerator: (Overhead + Desired Profit) ÷ Contribution Margin. The calculator keeps the two figures in clearly separate sections so the floor is never confused with the target.

Break-Even vs Cash Flow

Break-even is an operating model; cash flow is a timing model. Slow customer payments, weekly payroll against monthly billing, deposits, retainage and loan payments can leave a company short of cash in a month that clears break-even on paper. Both models are worth maintaining, and neither substitutes for the other.

The modeled margin should also be verified against real results — electrical job costing explains the process, and the job cost calculator compares estimated versus actual margin on a completed job. For the complete model, read the break-even revenue guide.

Frequently Asked Questions

Break-even revenue is the sales level at which the contribution generated by the company's work covers its modeled operating overhead, leaving approximately zero operating profit under the assumptions entered. It is a revenue floor, not a goal.

Divide annual operating overhead by your contribution margin expressed as a decimal. At $300,000 of overhead and a 40% contribution margin, break-even revenue is $300,000 ÷ 0.40 = $750,000. Enter your own figures above — the calculator uses your assumptions, not industry averages.

No. Break-even covers modeled overhead only. To include a profit target, add the desired profit dollars to overhead before dividing by the contribution margin — that is what the optional Desired Annual Operating Profit input does.

Use the percentage of revenue your own pricing model leaves after the direct or variable job costs you include in it. This calculator does not recommend a percentage — the correct figure depends on your cost structure, pricing and job mix, and is best validated against actual job-cost results.

Overhead is the numerator of the calculation. At an unchanged contribution margin, every dollar of additional overhead raises the revenue required to break even. Keeping the overhead figure complete and current is what keeps the break-even figure honest.

Yes. Enter a desired annual operating profit in the optional field and the calculator adds it to overhead before dividing: (Overhead + Desired Profit) ÷ Contribution Margin. The result appears as a separate profit-goal section so it is never confused with pure break-even.

No. Break-even revenue is an operating model based on revenue earned and costs incurred. Cash-flow break-even depends on timing — customer payment terms, payroll dates, deposits, retainage and tax obligations. A company can pass one and struggle with the other.

Because contribution margin is the divisor. Each revenue dollar contributes only its margin share toward overhead, so a smaller share means more revenue is needed to produce the same contribution dollars. A $300,000 overhead breaks even at $750,000 at 40% margin, but at $1,000,000 at 30%.

Break-Even Is One Part of Pricing

The revenue floor is set by overhead and margin — and both are produced by decisions elsewhere: the labor rate, overhead recovery, markup discipline and job costing. The pricing and profitability hub connects those pieces, and Contractor Core walks through them as a system.
