Break-even Calculator

Calculate break-even units and revenue from fixed costs, unit price, and variable cost per unit.

Calculation runs locally in your browser. Numbers are not uploaded, stored, fetched, or logged.

Informational planning estimate only — confirm actual costs, taxes, fees, and accounting requirements separately.

Contribution per unit
27.00
Contribution margin
60.00%
Break-even units

Break-even revenue
20,000.00

Formula: break-even units = fixed costs ÷ (price per unit − variable cost per unit).

Break-even calculator workflow tips

Break-even math is useful before estimating ROI, bundle pricing, campaign targets, or capacity needs. Keep fixed and variable costs realistic so the unit target is useful.

Set the selling price

Use Markup Calculator or Profit Margin Calculator when price per unit still needs a sanity check.

Estimate return after break-even

Use ROI Calculator after you know total costs and an expected return amount.

Compare sale impact

Use Discount Calculator when a promotion lowers price per unit and changes contribution margin.

Example break-even calculation

With 12,000 fixed costs, a 45 price, and 18 variable cost per unit, contribution margin is 27 per unit. Break-even is about 444.44 units and 20,000 in revenue.

Informational estimate only — not financial, tax, accounting, legal, or investment advice.

What this tool does

Use this browser-local break-even calculator for simple unit economics, pricing notes, launch planning, and offer checks. It shows the contribution margin and the number of units needed to cover fixed costs.

Common use cases

Estimate break-even units and break-even revenue from fixed costs, unit price, and variable cost per unit for simple local unit-economics planning.

Use Break-even Calculator for quick planning math, pricing checks, estimates, or operational comparisons. Treat the result as informational and verify important business, legal, tax, or accounting decisions separately.

Compare a quick scenarioEnter non-sensitive numbers, dates, rates, margins, or assumptions when you need a lightweight estimate before updating a spreadsheet or memo.
Explain the resultKeep the inputs, units, rounding, and assumptions near the output so another person can review how the estimate was produced.
Escalate important decisionsUse the calculator for planning context only, then verify high-impact legal, tax, accounting, payroll, investment, or compliance questions separately.

How to use it

  1. Enter fixed costs, price per unit, and variable cost per unit.
  2. Review contribution margin, contribution margin percentage, break-even units, and break-even revenue.
  3. Use the output as a planning estimate and separately verify taxes, accounting treatment, inventory costs, and actual business requirements.

Example workflow

Enter the known values, review the assumptions and calculated result, then compare scenarios by changing one number at a time. Use the output for lightweight planning, not as professional financial, tax, legal, or accounting advice.

4 focused answers for this page

What is the break-even formula?

Break-even units equal fixed costs divided by contribution margin per unit. Contribution margin is price per unit minus variable cost per unit.

What if variable cost is higher than price?

The calculator shows an error because the unit does not contribute toward fixed costs when variable cost is equal to or greater than price.

Is this accounting advice?

No. This tool provides informational estimates only and is not financial, tax, accounting, legal, or investment advice.

Are my cost numbers uploaded?

No. Break-even calculations run locally in your browser and ClearUtils does not upload, store, fetch, or log entered numbers.
