Break-even analysis answers the most basic question in business: how many units do I need to sell to cover my costs? It separates costs into fixed (rent, salaries, software) and variable (per-unit production or fulfilment) and finds the volume at which revenue equals their sum.
Once below break-even, every additional sale reduces the loss. Once above it, every additional sale becomes pure contribution to profit (minus any incremental variable costs). The lower your break-even, the lower your business risk.
Two levers move it: reduce fixed costs or increase the per-unit contribution margin (price minus variable cost). Cutting fixed costs usually lowers break-even faster than raising prices, because price hikes risk reducing demand.
Break-even units = Fixed costs / (Price per unit − Variable cost per unit)
A coffee shop with CHF 8,000 monthly fixed costs, a CHF 1.20 variable cost per coffee and a CHF 4.50 selling price needs to sell 2,424 coffees per month to break even.
