⚖️ Break-even Calculator

Find break-even units and revenue where total cost equals total revenue, with fixed cost, variable cost, and price inputs.

Break-Even Units — When Revenue Covers Fixed Costs

BrainyCalculators editorial insight — unique to this tool

Break-even quantity = fixed costs ÷ (price − variable cost per unit). A food truck with ₹20,000 monthly fixed costs selling plates at ₹150 with ₹60 variable cost needs ~222 plates/month to break even. SaaS with near-zero marginal cost breaks even on subscriber count against monthly burn. Sensitivity to price cuts is steep — a 10% discount can raise break-even units disproportionately.

When to use this calculator

Use to find minimum sales volume before profit. For margin percentage on each unit, use Profit Margin; for ROI on capital deployed, use ROI.

Reference Value Context
Formula FC ÷ (P − VC) Per-unit basis
Restaurant target 30–35% food cost Variable cost benchmark
SaaS marginal cost ~$0 BE = FC ÷ ARPU
10% price cut ↑ BE units Non-linear impact

What is Break-even Analysis?

Break-even analysis finds how many units or how much revenue is needed so profit equals zero, given fixed costs, variable cost per unit, and selling price.

Use this page for launch planning and pricing sensitivity. Profit and loss reports actual or projected margin on sales; break-even finds the zero-profit threshold.

Cash flow tracks timing of money in and out across months; break-even is a per-unit economics snapshot.

Break-even Formula

Break-even Units = Fixed Costs ÷ (Price − Variable Cost per Unit)

The denominator (Price − Variable Cost) is called the Contribution Margin — how much each sale contributes toward covering fixed costs.

Example

Fixed costs $10,000, variable cost $30/unit, price $50/unit.

Contribution Margin = $50 − $30 = $20
Break-even Units = $10,000 ÷ $20 = 500 units
Break-even Revenue = 500 × $50 = $25,000

How the Break-even Calculator Works

Formula, assumptions, and calculation steps for this business tool.

Formula Used

Break-even Units = Fixed Costs / (Selling Price per Unit - Variable Cost per Unit)

Methodology

Business calculators combine revenue, cost, margin, productivity, or pricing inputs into operating metrics that can be compared across scenarios.

Calculation Steps

  1. Enter the business quantities, prices, costs, or rates.
  2. Separate fixed values from variable values where the formula requires it.
  3. Calculate the metric using standard business arithmetic.
  4. Return the headline result with supporting totals or percentages.

Assumptions and Limits

  • Inputs should represent the same period or business unit.
  • One-time and recurring costs should not be mixed unless the calculator explicitly supports them.
  • Results are planning estimates and may differ from accounting statements.

Frequently Asked Questions

The break-even point is the level of sales at which total revenue equals total costs, meaning zero profit and zero loss. Every unit sold above break-even generates pure profit.

Contribution margin = Price − Variable Cost per unit. It represents how much each sale contributes to covering fixed costs. Once fixed costs are covered, contribution margin becomes profit.

You can lower break-even by: (1) reducing fixed costs, (2) reducing variable costs, (3) raising prices, or (4) improving your product mix to favor higher-margin items.

Break-even analysis tells you the minimum sales needed to stay in business, helps with pricing decisions, evaluates new product viability, and shows the impact of cost changes on profitability.

Real-World Applications

🏭
Manufacturing
Manufacturers calculate break-even units before committing to a production run, determining whether projected sales volumes justify the fixed costs of tooling, machinery, and factory overhead.
🍽️
Restaurant & Food Service
Restaurants operate on thin margins and high fixed costs. Break-even analysis reveals the minimum daily covers needed to cover rent, staff, and utilities before generating profit.
💻
SaaS & Software
SaaS companies calculate break-even MRR (monthly recurring revenue) needed to cover fixed engineering and support costs, helping plan the subscription pricing and growth targets.
📦
E-commerce & Retail
Online sellers use break-even analysis to set minimum order quantities for custom products, evaluate advertising spend, and determine the minimum product price after COGS and platform fees.
🏥
Healthcare Clinics
Private clinics use break-even to calculate the minimum patient volume or procedure mix needed to cover practitioner salaries, rent, equipment lease, and insurance premiums.
🎬
Entertainment & Events
Event producers calculate the ticket volume needed to cover venue, production, talent, and marketing costs — the audience size below which the event runs at a loss.

Common Mistakes

1
Misclassifying Costs as Fixed or Variable
Semi-variable costs (utilities, sales commissions with a base) are often incorrectly treated as purely fixed or purely variable. Misclassification leads to an inaccurate break-even calculation.
2
Ignoring Multiple Products
The basic break-even formula assumes a single product. If you sell multiple products at different margins, you need a weighted average contribution margin — otherwise the break-even point will be wrong.
3
Using Average Price Instead of Net Price
Your selling price should be the net revenue per unit after discounts, returns, and payment processing fees. Using a gross price overstates contribution margin and understates break-even volume.
4
Treating Break-even as a Target
Break-even is the no-profit, no-loss point — not a business goal. A healthy business targets profit well above break-even. Use the target profit input to plan for meaningful financial returns.
5
Not Updating as Costs Change
Fixed costs are not truly fixed forever — rent increases, staff are hired, equipment is added. Recalculate break-even whenever your cost structure changes significantly.

Typical Contribution Margins by Industry

Industry Typical CM Ratio Key Fixed Costs
SaaS / Software 60–80% Engineering, hosting, support salaries
Professional Services 50–70% Staff salaries, office, insurance
Restaurant 30–50% Rent, staff, utilities, permits
Retail (product) 20–40% Store rent, staff, inventory
Manufacturing 20–45% Factory, equipment, tooling
E-commerce 15–35% Marketing, platform fees, fulfilment
