$
Fixed Costs. Monthly costs that don't change with sales volume — rent, salaries, software subscriptions. Keep under: < 25% of revenue.
$
Variable Cost Per Unit. Costs that scale with each sale — product cost, packaging, payment fees, shipping. Healthy contribution margin: 20–35%.
$
Price Per Unit. The selling price of your product. Consider your positioning and competitor pricing.

WHAT'S A HEALTHY CONTRIBUTION MARGIN?

Contribution Margin Benchmarks

Where your contribution margin (CM) falls determines how quickly you can reach break-even. These are the same bands our Contribution Margin calculator uses. Here, contribution is your price minus the per-unit costs you entered, so include ad spend per order in variable cost for a like-for-like reading.

Below 0%NegativeEach sale costs more than it brings in, so selling more loses more.

How we calculate the sales volume needed to cover your costs.

Contribution Margin
Price per Unit − Variable Cost per Unit

Example: $50 − $25 = $25 per unit

Break-Even Units
Fixed Costs ÷ Contribution Margin

Example: $10,000 ÷ $25 = 400 units

Break-Even Revenue
Break-Even Units × Price per Unit

Example: 400 × $50 = $20,000

Daily Units Needed
Break-Even Units ÷ 30 days

Example: 400 ÷ 30 = 13.3 units/day

Safety Margin
((Current Sales − Break-Even) ÷ Current Sales) × 100

Example: ((600 − 400) ÷ 600) × 100 = 33%

The target is 400 units per month. We’d compare it with actual monthly unit sales.

We’d try a quieter month in the model to see how much room remains.

About break-even

What is a break-even point?

Your break-even point is the number of sales it takes to cover all your costs for the month. Below it you lose money on the month; every sale above it is profit. Knowing it turns "are we doing OK?" into a number you can check each week, and shows how much a price change or a cheaper supplier would move it.

Formula

Break-even units = monthly fixed costs ÷ (price − variable cost per unit)

Price minus variable cost is your contribution margin: what each sale leaves to pay the fixed bills like rent, salaries and software.

A worked example

  1. Your fixed costs are $10,000 a month. You sell at $50 and each unit costs $25 to make, pack and ship.
  2. Each sale leaves $25 (50% of the price).
  3. $10,000 ÷ $25 = 400 units, or $20,000 in sales, to break even.
  4. You sell 500 a month, so sales could fall 20% before you stop covering costs. That lands in Comfortable on the ladder.

How far above break-even is enough?

Breaking even is the floor, not the goal. What matters is your safety margin: how far sales can drop before you stop covering costs. Add your current monthly sales above and the calculator grades it on this ladder:

Below 0%
Below Break-Even.
0–20%
Thin.
20%+
Comfortable.

Without current sales, the calculator grades your contribution margin instead, on the same ladder as the contribution margin calculator.

FAQ

Frequently asked questions

Common questions about break-even analysis and profitability

The break-even point is the number of units you need to sell in a period to cover all fixed and variable costs — earning exactly $0 profit. Every unit sold above break-even generates contribution margin that becomes profit.

Calculate break-even units before launching to understand how many you need to sell to cover costs. This helps set realistic sales targets, marketing budgets, and inventory levels.

Contribution margin (price minus variable costs) shows how much each sale contributes toward covering fixed costs and generating profit. Higher contribution margin = fewer sales needed to break even.

Our calculators use industry-standard formulas and are designed for directional accuracy. Results depend on the quality of your input data. For precise financial planning, we recommend validating results with your accountant or financial team.

Yes, completely free with no hidden costs. We offer these tools to help ecommerce brands succeed. We may occasionally share relevant insights via email if you opt in, but the tools remain free forever.

Your calculations run in your browser, and we don't store the numbers you type unless you choose to send them — by unlocking a benchmark, emailing yourself a report, or contributing an anonymous data point. We do record anonymous usage events, which tool was used rather than what you entered. The AI tools work differently: your store URL and the report or concepts we generate are saved so we can support you and so your share link keeps working. We never access your Shopify admin, your customer data, or any private account information.
