• Setting a realistic minimum sales target.

Business Break-even Analysis Calculator: limits and things worth knowing

• In revenue terms, break-even = fixed costs ÷ contribution margin ratio. £120,000 of fixed costs at a 40% contribution margin needs £300,000 of revenue.
• The contribution margin ratio, not the profit margin, is the correct denominator — using net margin substantially overstates the required revenue.
• Break-even ignores timing. A business can be above break-even annually and still fail on seasonal cash flow.
• Recalculate whenever fixed costs change. Adding a salary moves the target immediately and by more than most people expect.
