Multi-Product Break-Even Calculator
Break-even across a product range, weighted by the sales mix. The answer depends on the mix as much as on the costs, so a month that hits its unit target through the wrong products can still miss break-even.
Also called: sales mix break even, weighted break even calculator.
960 units in total at the current mix, which is $1,392,000.00 of revenue. The weighted contribution is 625 a unit across the current mix. Premium contributes 1400 and Basic only 300, so the mix matters as much as the volume. Selling nothing but Premium would break even at 429 units against 960 at the current mix. A month that hits its unit target through the wrong products can still miss break-even, which is the failure this page exists to make visible.

| Product | Share of units | Price | Contribution | Margin | Units at break-even |
|---|---|---|---|---|---|
| Basic | 50% | $800 | $300 | 37.5% | 480 |
| Standard | 30% | $1,500 | $650 | 43.3% | 288 |

How this is calculated
With several products there is no single break-even volume, only one for a given mix. The weighted contribution per unit is the average across the mix, and the break-even is the fixed cost over that average. This is why a sales team hitting its unit target can still miss the number: selling the same volume weighted toward the low-contribution product lowers the average and raises the break-even. The page shows what the break-even would be if the mix shifted entirely to the best product, which brackets how much the mix is worth.

Method and limits
What it assumes
- The sales mix holds at the break-even volume, which is the whole basis of the calculation.
What it deliberately does not model
- Products that share capacity or cannibalise each other are not independent, and the mix cannot simply be chosen.
- Fixed costs attributable to a single product should be handled separately rather than pooled.

Frequently asked questions
- Why does the mix change the break-even?
- Because each product contributes a different amount per unit. The break-even divides by the weighted average, so shifting sales toward the lower-contribution product raises the volume needed.
