Visual Unit Economics Split (Contribution vs Variable Cost)
How Break-Even Analysis Works (Step-by-Step)
Finding the exact volume where total business revenue equals total fixed plus variable costs:
Per-Unit Contribution Margin
Subtract variable cost per unit from selling price per unit to find cash contribution toward fixed overhead per sale.
Break-Even Volume Units
Divide total periodic fixed costs by unit contribution margin to calculate minimum units required for zero net profit/loss.
Break-Even Revenue Dollar Target
Multiply break-even unit volume by unit selling price or divide fixed costs by contribution margin ratio percentage.

Frequently Asked Questions
What is the difference between fixed and variable costs?
Fixed costs (rent, insurance, base salaries) remain constant regardless of sales volume, whereas variable costs (materials, shipping commission) scale directly with production count.
What happens if my variable cost exceeds unit selling price?
If contribution margin is negative or zero, every unit sold deepens your loss rather than paying down fixed overhead.
Can I use this for multi-product businesses?
For mixed product portfolios, substitute average blended contribution margin ratio across projected sales mix percentages.
