A café sells lattes at $5 with $1.50 ingredient cost. Calculate how many drinks needed to cover rent and salaries.
→ Break-even: ~2,286 drinks/month (~76/day)

A professional uses the Break-Even Calculator during client work to produce accurate numbers quickly without opening a spreadsheet.
Include all fixed costs: rent, insurance, salaries, software subscriptions, and depreciation. Underestimating fixed costs makes break-even look easier than it is.
Each product has its own contribution margin. Calculate break-even per product line, not with blended averages across different margins.
