How Break Even is Calculated
Break even analysis finds the exact point where total revenue equals total costs — zero profit, zero loss. Below it you are losing money. Every unit above it generates pure profit.
Break Even Units = Fixed Costs ÷ Contribution Margin
Break Even Revenue = Fixed Costs ÷ Gross Margin %
Margin of Safety = (Current Sales − Break Even Sales) ÷ Current Sales × 100
Same business: BEP Revenue = $50 × 267 = $13,333/month
Contribution Margin: The Heart of Break Even Analysis
Contribution margin (CM) is the amount each unit sold contributes toward covering fixed costs and — once fixed costs are covered — generating profit. It is selling price minus variable cost, and it is the most important single number in break even analysis.
A higher contribution margin means you need fewer units to cover fixed costs. A lower CM means you need more volume to break even. When evaluating whether to lower prices (to increase volume) or raise them (to increase margin), the CM is the number that shows you the trade-off.
| Fixed Costs | Contribution Margin | Break Even Units | What it means |
|---|---|---|---|
| $5,000 | $10 | 500 units | Low CM — high volume required |
| $5,000 | $25 | 200 units | Average CM — manageable volume |
| $5,000 | $50 | 100 units | Strong CM — low volume needed |
| $5,000 | $100 | 50 units | Premium CM — minimal volume to profit |
How Far Above Break Even Are You?
The margin of safety measures how much your current sales can fall before you hit break even — your buffer against downturns. It is expressed as a percentage of current sales.
You can absorb a 33% revenue drop before losing money
A margin of safety above 25% is generally considered healthy. Below 10% means any small downturn — a quiet month, a lost client, a supply disruption — could push you into loss.
3 Ways to Lower Your Break Even Point
- Reduce fixed costs. Every dollar removed from fixed costs reduces your break even by 1 ÷ CM units. If your CM is $30 and you cut $3,000 in fixed costs, you lower break even by 100 units per month.
- Increase selling price. A higher price increases contribution margin directly. Raising price from $50 to $55 on a $20 variable cost lifts CM from $30 to $35 — a 17% improvement that reduces break even by 14%.
- Reduce variable cost per unit. Better supplier terms, volume discounts, or production efficiencies all improve CM and reduce break even. Even a $2 reduction per unit on $30 CM is a 7% improvement.
