The most basic viability test of any business: how much do we need to sell just to cover our costs? Above break-even, every dollar of incremental revenue starts contributing to profit. Below it, you're losing money on every sale.
Definition
Break-Even Point - the level of revenue (or unit volume) at which total revenue equals total costs - the business neither makes nor loses money. Below this point: a loss. Above: profit.
Formula
Break-Even Revenue = Fixed Costs ÷ Contribution Margin Where Contribution Margin = 1 − (Variable Cost ÷ Revenue) Example: $40K fixed costs, 65% contribution margin. Break-even = $40K ÷ 0.65 = $61.5K revenue.
Common uses
- Pricing decisions - shows the impact of price changes on the required volume
- Startup viability - is reaching break-even realistic with current assumptions?
- Downturn planning - how far can revenue drop before you're losing money?
Watch out
Break-even doesn't account for cash timing. A business at break-even on the P&L can still have cash flow problems because of receivables and working capital.
