How to Calculate Break-Even for Any Local Business (With a Free Calculator)
Break-even analysis answers one specific question: how many units, jobs, or visits do you need to sell each month before you start actually keeping any profit? It's the single most useful early-stage number for any local business, and it takes about thirty seconds to calculate correctly once you know the formula.
The formula itself is simple: break-even units = fixed monthly costs ÷ (price per unit − variable cost per unit). The tricky part for most first-time founders isn't the math — it's accurately separating fixed costs from variable costs in the first place.

Fixed costs are the expenses that don't change with how many jobs you do — rent, insurance, loan payments, software subscriptions. Variable costs scale directly with each sale — materials, fuel, hourly labor tied to a specific job. Get those two categories right and the formula does the rest.
