How do I calculate the break-even point in units?

Break-even units equals Fixed Costs divided by (Selling Price minus Variable Cost per Unit). For example, with $5,000 monthly fixed costs, a $4.50 selling price, and $1.50 variable cost, the break-even point is 5,000 / (4.50 - 1.50) = 1,667 units per month. Each unit sold beyond that point generates profit equal to the contribution margin.

What is the contribution margin and why does it matter?

Contribution margin is the difference between selling price and variable cost per unit. It represents how much each unit sold contributes toward covering fixed costs and generating profit. The contribution margin ratio is (Price - Variable Cost) / Price, expressed as a percentage. A higher contribution margin means fewer units needed to break even.

How do I find the minimum price I need to charge to break even?

Minimum price to break even equals (Fixed Costs / Expected Units) + Variable Cost per Unit. For example, with $8,000 fixed costs, 1,500 expected units, and $3 variable cost: Minimum price = (8,000 / 1,500) + 3 = $8.33 per unit. Pricing higher than this generates profit; pricing lower means a loss.

How does a sensitivity analysis help with break-even planning?

A sensitivity analysis shows how your break-even point changes when price or variable costs shift by 10% or 20%. This helps you understand risk: if costs rise 10%, how many more units must you sell? If you lower prices 20% to compete, what happens to your break-even? The What-If tab generates a full sensitivity table automatically.

Does this break-even calculator include taxes or country-specific data?

No — this is a universal pre-tax break-even calculator based on standard cost-volume-profit (CVP) analysis. It works with any currency and any business. Tax rates vary by country and business structure. For country-specific business calculators, see the links below the calculator for US, UK, Germany, India, Australia, Canada, and New Zealand.

How to Use This Calculator

Tab "Break-Even Point"

Enter your monthly fixed costs (rent, salaries, insurance), variable cost per unit (materials, packaging, shipping), and selling price per unit. The result shows how many units you need to sell to cover all costs, plus the corresponding revenue target.

Tab "Profit Zone"

Same inputs as Tab 1, plus a target profit amount. The calculator shows how many units you need to sell to both cover costs and hit your profit goal, and how many extra units that is beyond the basic break-even point.

Tab "What-If Scenarios"

Enter three different price/cost combinations to see how break-even shifts. Use this to test pricing strategies: raising your price, lowering variable costs, or both. The scenario with the fewest break-even units is highlighted as the lowest-risk option.

The Formulas

Break-even point (units):
Break-even units = Fixed Costs / (Selling Price − Variable Cost per Unit)

Contribution margin:
Contribution Margin = Selling Price − Variable Cost per Unit

Contribution margin ratio:
CM Ratio = Contribution Margin / Selling Price

Break-even revenue:
Break-even Revenue = Fixed Costs / CM Ratio

Units for target profit:
Units = (Fixed Costs + Target Profit) / Contribution Margin per Unit

All calculations use standard cost-volume-profit (CVP) analysis. No country-specific tax rates are applied. Results are pre-tax estimates.

Worked Examples

Example 1 — Coffee Shop: $5,000/mo fixed, $1.50 variable, $4.50 selling

A coffee shop has $5,000 in monthly fixed costs (rent, staff, utilities). Each cup costs $1.50 in ingredients and packaging (variable cost) and sells for $4.50.

Fixed costs (monthly)$5,000

Variable cost per unit$1.50

Selling price per unit$4.50

Contribution margin$4.50 − $1.50 = $3.00

Break-even units$5,000 / $3.00 = 1,667 cups/month

Break-even revenue1,667 × $4.50 = $7,500/month

The shop needs to sell at least 1,667 cups per month (about 56 per day) just to cover costs. Every cup beyond 1,667 generates $3.00 of pure profit.

Example 2 — SaaS: $20,000/mo fixed, $2 variable, $30 subscription

A SaaS company has $20,000 in monthly fixed costs (servers, salaries, office). Each user costs $2/month in infrastructure (variable cost) and pays a $30/month subscription.

Fixed costs (monthly)$20,000

Variable cost per user$2.00

Subscription price$30.00

Contribution margin$30.00 − $2.00 = $28.00

Break-even users$20,000 / $28.00 = 714 users/month (rounded from 714.3)

Break-even MRR714 × $30.00 = $21,420/month

The company needs 714 paying subscribers to break even. The high contribution margin ratio (93.3%) means most of each subscription goes toward covering fixed costs and profit.

Example 3 — Same SaaS with $10,000 profit target

Using the same SaaS numbers, the founder wants to earn $10,000/month in profit on top of covering all costs.

Fixed costs + target profit$20,000 + $10,000 = $30,000

Contribution margin per user$28.00

Units needed$30,000 / $28.00 = 1,071 users (rounded from 1,071.4)

Revenue needed1,071 × $30.00 = $32,130/month

Extra users above break-even1,071 − 714 = 357 users

An additional 357 subscribers beyond the break-even point generates the target profit. Each extra user contributes $28 straight to the bottom line.

Understanding Break-Even Analysis

What Is Break-Even?

The break-even point is where total revenue equals total costs — you are neither making a profit nor taking a loss. It is the minimum sales volume you need to sustain your business. Below break-even you lose money; above it, every additional unit sold generates profit equal to the contribution margin.

Fixed vs Variable Costs

Fixed costs remain the same regardless of how many units you sell: rent, salaries, insurance premiums, loan payments. Variable costs change in proportion to sales volume: raw materials, packaging, shipping fees, transaction fees. Correctly classifying costs into these two categories is essential for accurate break-even analysis.

Contribution Margin

The contribution margin is the amount each unit sold contributes toward covering fixed costs. Once all fixed costs are covered (break-even), the entire contribution margin becomes profit. A higher contribution margin means fewer units needed to break even — which is why SaaS businesses (with low variable costs) often have lower break-even thresholds relative to their fixed costs.

Limitations

Break-even analysis assumes: (1) costs can be cleanly split into fixed and variable, (2) selling price and variable cost per unit stay constant regardless of volume, (3) everything produced is sold. In reality, economies of scale, bulk discounts, and demand curves add complexity. Use break-even as a starting point, not the final word.

Frequently Asked Questions

How do I calculate the break-even point?▼

Divide your total fixed costs by the contribution margin per unit (selling price minus variable cost). For example, $5,000 fixed costs with a $3.00 contribution margin per unit means you need 1,667 units to break even. In revenue terms, divide fixed costs by the contribution margin ratio.

What is the contribution margin ratio?▼

The contribution margin ratio is the contribution margin divided by the selling price. If a product sells for $4.50 and the variable cost is $1.50, the contribution margin is $3.00 and the ratio is 3.00 / 4.50 = 66.67%. This means 66.67 cents of every dollar of revenue goes toward covering fixed costs and profit.

How many units do I need to sell to reach a target profit?▼

Add your target profit to your fixed costs, then divide by the contribution margin per unit. For a SaaS with $20,000 fixed costs, $28 contribution margin, and a $10,000 profit goal: (20,000 + 10,000) / 28 = 1,071 users. The "Profit Zone" tab does this calculation automatically.

Does raising the price always lower the break-even point?▼

Yes, mathematically. A higher price increases the contribution margin per unit, so fewer units are needed to cover fixed costs. However, a higher price may reduce demand. Use the "What-If Scenarios" tab to test different price points and find the sweet spot between margin and volume.

Does this calculator include taxes?▼

No. This is a universal pre-tax break-even calculator using standard cost-volume-profit (CVP) math. Tax rates vary by country, business type, and income level. For country-specific calculators, use the country links below. To include taxes manually, increase your target profit to account for the tax you expect to pay.
