Break-even point

Updated

Definition

The break-even point is the revenue at which your business makes zero profit: gross profit from jobs exactly covers overhead. For a contractor, break-even revenue equals fixed overhead divided by gross margin, written as a decimal.

Also called: Break-even revenue, Breakeven

The formula

Every job leaves some gross profit after its direct costs. Overhead (rent, insurance, office wages, marketing, software, phones) has to be paid whether or not jobs come in. You break even when the gross profit from your jobs adds up to exactly your overhead.

  • Break-even revenue = Overhead ÷ Gross margin (as a decimal)
  • Break-even jobs = Overhead ÷ Average gross profit per job

Use the same period on both sides: monthly overhead gives monthly break-even revenue.

Example: A two-truck HVAC shop has $20,000 a month of overhead and runs a 40% gross margin. Break-even revenue is $20,000 ÷ 0.40 = $50,000 a month. If an average service call leaves $400 of gross profit, the shop needs 50 calls a month before it earns a dollar. At $60,000 of revenue it keeps $4,000 ($60,000 × 0.40, minus $20,000). At $45,000 it loses $2,000. The numbers are made up for illustration.

Why it's worth knowing

Break-even turns overhead into a target you can see on the schedule. It answers practical questions:

  • Can I afford this hire or this truck? Add the monthly cost to overhead and recompute. For example, a $5,000 a month office hire at a 40% gross margin raises break-even by $12,500 of revenue a month.
  • Is a price increase worth it? A higher gross margin lowers break-even without a single extra job.
  • How bad is the slow season? Compare break-even with what you booked in the same months last year. The gap is what you need in reserve or in off-season work. Cash flow planning starts here.

Common mistakes

  • Using markup instead of margin. For example, a 50% markup is only a 33.3% margin. Say you divide overhead by 0.50 instead of 0.333: you set the bar a third too low. Markup vs margin shows the conversion.
  • Leaving out your own pay. If you take draws instead of a wage, the break-even you calculate is the point where you work for free. Count a fair wage for your field hours in job costs and a fair wage for your office and sales time in overhead.
  • Leaving field labor in overhead. That inflates gross margin and overhead together, and the break-even it produces doesn't match how your costs actually move with volume. Field labor belongs in cost of goods sold.
  • Forgetting yearly bills. Insurance premiums, license renewals and vehicle replacement don't show up every month. Spread them across the year in your overhead figure.
  • Treating break-even as cash. Loan principal isn't an expense on the profit and loss statement, but you still have to pay it. To see the revenue that keeps the bank account steady, add monthly loan principal to overhead before you divide.

How it connects

Break-even sits between overhead and gross margin: lower one or raise the other and it moves down. Your P&L supplies both numbers each month, and how to read a profit and loss statement walks through a sample month where overhead and margin set the revenue the shop needs. When you set your hourly rate, the same overhead is spread over billable hours instead, as how to set your labor rate shows.
