What this calculator works out
Useful for product, service and project planning when you know the average selling price and variable cost.
Calculation: Break-even units = fixed costs ÷ (price − variable cost).
Practical example
At a 120 selling price, 45 variable cost and 9,000 fixed costs, contribution is 75 and break-even is 120 sales or 14,400 revenue.
Use the result carefully
- If variable cost equals or exceeds price, there is no positive break-even point.
- Round units up because a partial sale may not be possible.
- Results depend on the average price and cost assumptions staying stable.
