Break-Even Calculator - Units and Revenue (2026)

What Is Break-Even and Why Does It Matter in 2026?

Break-even is the sales level where total revenue equals fixed plus variable costs, producing zero operating profit. Below it you lose, above it each extra unit contributes its $50 margin straight to profit. For $10,000 fixed, $80 price and $30 variable cost, break-even is 200 units and $16,000 revenue; the 201st unit adds $50 profit, the 300th cumulative profit is $5,000 (100 units × $50). That clarity focuses pricing, volume and cost decisions. According to the U.S. Census Bureau Annual Business Survey 2023, employer businesses averaged about $1.4 million in receipts, so a $16,000 break-even is a small slice that must be precise (Source: U.S. Census Bureau, census.gov). This calculator isolates fixed vs variable to find that point and the extra units needed for any profit target.

Fixed Costs vs Variable Costs: How Do I Split Them Correctly?

Fixed costs stay flat in the relevant range: base rent, salaried admin, insurance, base SaaS. Variable costs rise per unit: materials, packaging, payment processing at about 2.9% + $0.30 per transaction, shipping and commission. Mixed costs like utilities have a fixed base plus a variable kWh charge; split them. Step costs like a second oven at 300 units raise fixed costs discretely.

Misclassifying a $5 variable as fixed understates break-even by 100 units on $10,000 fixed at $50 margin, so verify with accounting records. Use the Profit Margin Calculator to see how the same costs flow to gross versus contribution margin.

What Happens If I Raise Price by $10 or Cut Variable Cost by $5?

Contribution margin amplifies small price moves. At $10,000 fixed and $30 variable, a $80 price gives $50 margin and 200 break-even units; raising to $90 gives $60 margin and 167 units, saving 33 units and $1,040 in break-even revenue ($16,000 vs $15,030) — but only if volume holds. Cutting variable from $30 to $25 at $80 price raises margin to $55 and cuts break-even to 182 units, saving 18 units and $1,440 (Source: BLS Producer Price Index — bls.gov/ppi).

Price elasticity can erase the math: a $10 price hike needs less than 17% volume loss to remain profitable at $60 vs $50 margin. Test sensitivity before committing and validate demand with orders, not optimism.

How Do I Calculate Break-Even for a Target Profit or a Service Business?

Add the profit target to fixed costs: units = (Fixed + Target) / Margin. For a $20,000 target on $10,000 fixed at $50 margin, units are 600 and revenue is $48,000, exactly 400 units above break-even. A service business defines the unit as a billable hour: at $120 hourly price and $45 variable (contractor + software), margin is $75, so $15,000 monthly fixed needs 200 hours or 25 hours weekly per consultant.

Multi-product firms use weighted average margin: selling 60% at $50 margin and 40% at $30 margin gives $42 weighted, so $10,000 fixed needs 238 blended units versus 200 at pure $50 margin. Capacity then binds: 238 units may exceed a 200-unit oven limit, creating a $2,000 step fixed cost and raising break-even to 286 units.
