Break-Even Calculator 2026

Break-Even Units = Fixed Costs ÷ (Selling Price - Variable Cost Per Unit). The denominator is called the contribution margin per unit. Break-Even Revenue = Break-Even Units × Selling Price. To include a profit target: Break-Even Units = (Fixed Costs + Target Profit) ÷ Contribution Margin.

Contribution margin is the amount each sale contributes to covering fixed costs and profit: Selling Price - Variable Cost = Contribution Margin. A product selling for $100 with $60 variable cost has a $40 contribution margin (40%). Higher contribution margins mean fewer units needed to break even. Service businesses typically have 60–80% contribution margins; product businesses 20–50%.

Most small businesses take 2–3 years to reach profitability. However, some business types break even faster: online businesses and service businesses often reach break-even in 6–18 months. Restaurants typically take 2–4 years. Retail stores 2–3 years. Planning your break-even timeline before launch is critical for securing adequate startup capital.

Break-even is the point where total revenue equals total costs — zero profit, zero loss. Every sale above break-even contributes directly to profit at your contribution margin rate. Example: with a 40% contribution margin, $10,000 in sales above break-even produces $4,000 in profit. Reaching break-even is a major milestone but not the end goal — target 20–30% margin of safety above break-even for business stability and growth capital.

Margin of safety = (Current Sales - Break-Even Sales) / Current Sales × 100. It measures how far sales can drop before you start losing money. A 25% margin of safety means sales can decline 25% before hitting break-even. Below 15% margin of safety is risky — small revenue swings cause losses. Service businesses and SaaS companies often achieve 40–60% margins of safety; brick-and-mortar retail often operates at 10–20%.

Three strategies: (1) Reduce fixed costs — renegotiate rent, cut subscriptions, reduce headcount. Every dollar cut from fixed costs directly lowers break-even. (2) Raise prices — a 10% price increase on a 30% margin product reduces break-even volume by ~25%. (3) Improve product mix — sell more high-margin items and fewer low-margin items. Combination approach: most businesses can reduce break-even by 20–35% through modest price increases combined with targeted fixed cost reduction without major operational disruption.

Most full-service restaurants need $30,000–$80,000 in monthly revenue to break even. A 50-seat restaurant targeting a $15 average check needs 2,000–5,000 covers per month at break-even. Restaurant economics: food cost 28–35% of revenue, labor 30–35%, occupancy 8–12%. This leaves 20–30% gross margin to cover overhead — hence why restaurants fail at high rates. Thin margins with high fixed costs require consistently high volume with little room for slow months.

Break-even analysis is one of the most powerful pricing tools available. Start with your required break-even: Fixed Costs ÷ Expected Volume = Minimum Contribution Margin Per Unit Needed. Then: Minimum Price = Variable Cost Per Unit + Minimum Contribution Margin. Example: $5,000 fixed costs, expect to sell 200 units, variable cost $10/unit. Minimum contribution margin = $5,000 ÷ 200 = $25. Minimum price = $10 + $25 = $35. Then add your target profit margin on top — if you want 20% net margin: Price = $35 / (1 - 0.20) = $43.75. This approach ensures every price you set is backed by actual cost data rather than competitor guessing. Important: re-run this analysis whenever volume expectations, fixed costs, or variable costs change — all three shift your optimal price.
