Break-even point calculator

Break-even is the sales level where contribution margin exactly covers fixed costs. Below it every sale funds a loss; above it, each additional unit drops its full contribution margin into profit.

  • Every unit above break-even adds its full contribution margin straight to operating profit.

How to use this calculator

  1. 1Total your fixed costs for the period: rent, salaries, software, insurance, loan interest.
  2. 2Set the average selling price of one unit, job or subscription.
  3. 3Add the variable cost of delivering that unit: materials, freight, merchant fees, contractor time.
  4. 4Optionally enter current unit sales to see your margin of safety.

The formula behind the number

Break-even units = fixed costs / (price per unit − variable cost per unit). The denominator is contribution margin per unit: the cash each sale leaves behind after the costs that only exist because that sale happened.

Break-even revenue = break-even units x price. Where you sell many SKUs, run the calculation on a blended average price and average variable cost, or on your contribution margin ratio applied to total revenue.

Why buyers and lenders ask for it

Margin of safety — how far current sales sit above break-even — is a direct read on downside risk. A business trading 8% above break-even is fragile; one trading 60% above it can absorb a bad quarter without breaching covenants.

In a valuation context, a low margin of safety usually widens the risk discount applied to earnings, because forecast cash flows are more likely to miss.

Frequently asked questions

What if I sell services, not units?

Use one billable job, engagement or month of subscription as the unit. Price is your average invoice; variable cost is the direct labour and materials consumed by that job.

Should owner wages sit in fixed or variable costs?

A salaried owner is a fixed cost. Owner time billed per job behaves as a variable cost. Be consistent, because the split moves the break-even point materially.

What is a healthy margin of safety?

Most lenders are comfortable above 20-25%. Below 10% the business needs either a price rise or a fixed-cost reduction before it can survive a normal demand shock.
