How to Read Your Results
Break-even units are the minimum whole units required for estimated profit of zero.
Break-even revenue is based on the rounded-up unit result, so it can be above the exact unrounded threshold.
Contribution margin per unit shows how much one additional unit adds toward fixed costs or profit.
The contribution margin ratio helps compare products with different selling prices.
Units for target profit include both fixed costs and the optional profit amount.
Assumptions & Important Notes
- Each example uses one average selling price and one average variable cost per unit.
- Fixed costs apply to the same monthly or quarterly period stated in the scenario.
- All required units are assumed to be sold in that period.
- Amounts are illustrative estimates and exclude unentered taxes and costs.

Frequently Asked Questions
What is a good break-even point in units?
There is no universal good number. It depends on expected demand, operating capacity, available cash, and the reliability of the price and cost estimates.
Why can two businesses with the same revenue have different break-even points?
Their fixed costs, variable costs, and selling prices may differ. Break-even is driven by contribution margin, not revenue alone.
How does a profit target change the example?
The target profit is added to fixed costs before dividing by contribution margin per unit, increasing the required number of units.
Should discounts be included in these examples?
If discounts are expected regularly, using an average realized selling price can produce a more representative estimate.
