Break-Even Calculator — Free Units, Revenue & ROAS Break-Even Tool 2026
You’re selling a product at $1,200 with $20 in variable costs and $12,000 in monthly fixed costs. You think you need to sell maybe 20 units to break even. The actual number is 11. At 11 units, you generate exactly $13,200 in revenue — covering every dollar of fixed and variable cost. Unit 12 is your first dollar of profit.
Most businesses guess their break-even. This calculator shows the exact unit count, break-even revenue, contribution margin, profit at every sales volume from 3 units to your current sales level, and — for ecommerce and marketing teams — the minimum ROAS your ad campaigns need to be profitable.

Enter fixed costs, price per unit, and variable cost to calculate your break-even point
What This Break-Even Calculator Shows
Break-Even Point Calculator — Units and Revenue
Enter your total monthly fixed costs, price per unit, and variable cost per unit. The calculator instantly shows break-even units (the exact number of sales needed to cover all costs), break-even revenue (the dollar amount of sales required), and contribution margin in both dollars and percentage. Results update in real time as you adjust any input.
Profit at Different Sales Volumes — Scenario Table
The scenario table shows profit or loss at multiple sales volumes — below break-even, at break-even, and above break-even. This is what no competitor calculator shows. At 8 units: revenue $9,600, total cost $12,160, loss $2,560. At 11 units (break-even): revenue $13,200, total cost $12,220, profit $980. At 2,000 units: revenue $2,400,000, total cost $52,000, profit $2,348,000. The table makes the profit zone visual and scannable.
Contribution Margin Per Unit and Ratio
Contribution margin = Price − Variable Cost Per Unit. On the example: $1,200 − $20 = $1,180 contribution margin per unit. Contribution margin ratio = $1,180 ÷ $1,200 = 98.3%. This is the percentage of each sale that goes toward covering fixed costs and generating profit. High contribution margin ratios mean fixed cost leverage — each additional unit above break-even generates nearly the full sale price as profit.
Break-Even Time — From Zero Sales
The tool shows how long it takes to break even starting from zero sales, assuming a constant monthly sales rate. This answers the question startup founders and product managers ask most: “If we launch at X sales volume, when do we first cover our costs?”
Current Position Indicator
Enter your current or projected monthly sales volume and the tool shows exactly how many units above or below break-even you are, with a visual progress bar and your current monthly profit or loss at that volume.
How to Calculate Break-Even Point — The Formula
Break-Even Point Formula in Units
The formula to calculate break-even point is: Break-Even Units = Total Fixed Costs ÷ Contribution Margin Per Unit
Where: Contribution Margin Per Unit = Price Per Unit − Variable Cost Per Unit
Example: Fixed costs = $12,000/month. Price = $1,200. Variable cost = $20. Contribution margin = $1,200 − $20 = $1,180. Break-even units = $12,000 ÷ $1,180 = 10.17 units → rounded up to 11 units.
This break-even point calculation in units is the foundation of all break-even analysis — the number of units you must sell each period before generating any profit.
Break-Even Point Formula in Sales Dollars
Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio
Where: Contribution Margin Ratio = Contribution Margin Per Unit ÷ Price Per Unit
Example: CM ratio = $1,180 ÷ $1,200 = 0.983. Break-even revenue = $12,000 ÷ 0.983 = $12,207 (approximately $13,200 at exactly 11 units).
How to Calculate Break-Even Point in Dollars for Service Businesses
Service businesses often don’t sell discrete “units” — they sell hours, projects, or subscriptions. To calculate break-even in units (or client count), adapt the formula:
Price per unit → Average revenue per client/project/month. Variable cost per unit → Direct cost per client (contractor time, materials, software per client). Fixed costs → Rent, salaries, insurance, software subscriptions — costs that don’t change with client count.
A consulting firm with $18,000/month in fixed costs, $5,000 average project revenue, and $800 in variable cost per project: CM per project = $5,000 − $800 = $4,200. Break-even = $18,000 ÷ $4,200 = 4.3 projects/month.
Break-Even ROAS Calculator — The Most Overlooked Metric in Paid Advertising
What Is Break-Even ROAS?
Break-Even ROAS (Return on Ad Spend) is the minimum revenue your paid advertising must generate per dollar spent before your campaigns become profitable. Below break-even ROAS, every ad dollar is destroying value — even if your dashboard shows a “positive” return.
Break-Even ROAS Formula = 1 ÷ Gross Margin Percentage
A business with 40% gross margin: Break-Even ROAS = 1 ÷ 0.40 = 2.5x. This means you need $2.50 in revenue for every $1 of ad spend just to break even.
A business with 25% gross margin: Break-Even ROAS = 1 ÷ 0.25 = 4.0x. You need $4 in revenue per $1 spent before you make a single dollar of profit from ads.
How to Calculate Break-Even ROAS
Step 1: Calculate your gross margin percentage Gross Margin % = (Revenue − COGS) ÷ Revenue
On a $50 product with $30 COGS: Gross Margin = ($50 − $30) ÷ $50 = 40%.
Step 2: Apply the break-even ROAS formula Break-Even ROAS = 1 ÷ 0.40 = 2.5x
Step 3: Compare against your actual ROAS If your Google Shopping campaign is delivering 3.2x ROAS and your break-even is 2.5x, you’re profitable at the ad level. If you’re delivering 2.1x ROAS on a 2.5x break-even, you’re losing money even though 2.1x sounds positive.
Break-Even ROAS by Margin — Reference Table
| Gross Margin | Break-Even ROAS | Interpretation |
|---|---|---|
| 10% | 10.0x | Requires exceptional campaign performance to be profitable |
| 20% | 5.0x | Challenging — tight margin, high bar |
| 25% | 4.0x | Typical for fashion, accessories, low-margin retail |
| 33% | 3.0x | Common SaaS and consumer products target |
| 40% | 2.5x | Reasonable for mid-margin ecommerce |
| 50% | 2.0x | Favorable — most campaigns can achieve |
| 60% | 1.67x | Very favorable — high-margin digital products |
Most ecommerce brands celebrate a 3x or 4x ROAS without knowing whether it’s actually profitable for their margin structure. A 3x ROAS for a fashion brand with 25% margin means they’re losing money (need 4.0x). A 3x ROAS for a supplement brand with 60% margin means they’re highly profitable. Break-even ROAS makes this explicit.
Break-Even ROAS vs Target ROAS
Break-even ROAS is the floor — the minimum to avoid losing money at the ad level. Target ROAS should sit comfortably above break-even to cover attribution gaps, return rates, and scaling inefficiency.
General rule: set target ROAS at 1.5× to 2× your break-even ROAS. Break-even at 2.5x → Target ROAS: 3.75x–5.0x. Break-even at 4.0x → Target ROAS: 6.0x–8.0x.
Break-Even Sales Calculator — Revenue-Based Break-Even for Retailers
How to Calculate Break-Even Sales in Dollars
For businesses that don’t track unit sales — restaurants, service businesses, subscription models — the revenue-based break-even calculation is more useful than the unit-based formula:
Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio
Example: A restaurant with $25,000 in monthly fixed costs and a 65% contribution margin: Break-even revenue = $25,000 ÷ 0.65 = $38,462/month in sales required.
If the restaurant currently does $45,000/month in sales, it’s operating $6,538 above break-even — generating approximately $4,250 in monthly profit at the contribution margin rate.
Break-Even by Business Type
SaaS and Subscription
Fixed costs are typically high (engineering, infrastructure, customer success); variable costs are low per customer. High contribution margins (70%–85%) mean break-even is driven almost entirely by customer count. A SaaS company with $80,000 in monthly fixed costs at $500 MRR per customer and $25 variable cost:
CM per customer = $500 − $25 = $475. Break-even = $80,000 ÷ $475 = 169 customers.
Ecommerce / Product
Variable costs (COGS, shipping, payment processing, returns) are significant — often 40%–70% of revenue. Contribution margins of 30%–60% are common. Fixed costs include warehousing, staff, software, and marketing overhead.
Service Business / Agency
Low variable costs (primarily contractor time) and moderate fixed costs (office, staff, software). Contribution margins can be 50%–80% depending on how much work is done by employees vs. contractors.
Break-Even Analysis Calculator — How to Use the Results
What Break-Even Analysis Tells You
Break-even analysis answers four critical business questions:
How many units do I need to sell to not lose money? → Break-even units. How much revenue do I need to cover all costs? → Break-even revenue. What profit does each incremental sale generate? → Contribution margin per unit. How far am I from losing money if sales drop? → Margin of safety (current units − break-even units).
Margin of Safety — Your Buffer Against a Bad Month
Margin of safety = Current sales volume − Break-even volume.
At 2,000 units/month with a break-even of 11: margin of safety = 1,989 units. This business can absorb a 99.5% sales decline before becoming unprofitable. At 15 units/month with a break-even of 11: margin of safety = 4 units — a 27% sales drop puts you below break-even.
The margin of safety percentage = (Current volume − Break-even volume) ÷ Current volume × 100.
How to Improve Your Break-Even Point
Reduce fixed costs: Every dollar cut from fixed costs reduces break-even by (1 ÷ CM ratio) units. Cutting $1,000/month in fixed costs at a $1,180 CM reduces break-even by 0.85 units.
Increase price: Higher price increases contribution margin per unit, reducing break-even. A $100 price increase (from $1,200 to $1,300) on $20 variable cost raises CM from $1,180 to $1,280 — reducing break-even from 10.17 to 9.38 units.
Reduce variable costs: Lower COGS, shipping costs, or direct labor reduces variable cost per unit, increasing CM. Cutting $20 in variable cost (from $20 to $0 for a digital product) on $1,200 price raises CM to $1,200 — virtually identical break-even in this example, but for higher-variable-cost businesses (e.g., reducing $200 variable cost to $150), the impact is significant.
Social Security Break-Even — A Completely Different Calculator
Why Social Security Break-Even Is Separate
The keyword “social security break even calculator” appears in this cluster but refers to a completely different calculation: at what age do you break even on Social Security benefits depending on when you start claiming (62, 67, or 70)?
This is not a business break-even calculation. It requires different inputs: estimated monthly benefit at each age, life expectancy, and discount rate for the time value of money.
This tool handles business break-even only.
For Social Security break-even analysis, visit the SSA.gov benefit estimator or AARP’s Social Security calculator — both are built specifically for that calculation. The break-even age for Social Security (typically somewhere between 76–82 depending on your benefit amount) is unrelated to the contribution margin and fixed cost analysis this tool performs.

Frequently Asked Questions
What is a break-even calculator?
A break-even calculator estimates the number of units you must sell (or revenue you must generate) to cover all fixed and variable costs — the point where your business neither profits nor loses money. A complete break-even calculator shows contribution margin, profit at multiple sales volumes, and for marketing teams, the minimum ROAS required for profitable advertising.
How to calculate break-even point?
Break-even point in units = Fixed Costs ÷ (Price − Variable Cost). Break-even revenue = Fixed Costs ÷ Contribution Margin Ratio. Where contribution margin ratio = (Price − Variable Cost) ÷ Price. Every unit sold above break-even generates profit equal to the contribution margin per unit.
What is contribution margin?
Contribution margin is the amount each unit sale contributes toward covering fixed costs and generating profit. Formula: Price Per Unit − Variable Cost Per Unit. Contribution margin ratio = Contribution Margin ÷ Price. A $45 product with $12 variable cost has a $33 contribution margin and 73.3% contribution margin ratio — meaning 73 cents of every dollar sold covers fixed costs and profit.
What is break-even ROAS?
Break-even ROAS is the minimum Return on Ad Spend needed for paid advertising to be profitable. Formula: 1 ÷ Gross Margin Percentage. A business with 40% gross margin needs a 2.5x ROAS to break even on ad spend. Below this threshold, advertising is consuming more gross profit than it generates — even if the ROAS appears positive in your dashboard.
What is the difference between fixed costs and variable costs?
Fixed costs don’t change with sales volume — rent, salaries, insurance, software subscriptions. Variable costs increase with each unit sold — materials, direct labor, shipping, payment processing fees. The break-even formula works because fixed costs must be covered by contribution margin from each unit before any profit begins.
How do I use break-even analysis to set prices?
Use break-even analysis to evaluate pricing scenarios: enter your current costs, then adjust price per unit to see how break-even changes. Higher prices reduce break-even units (fewer sales needed to cover costs) but may reduce volume. Lower prices increase break-even units but may capture more market share. The scenario table shows profit at multiple sales volumes for each price point you want to test.
Why is my break-even higher than expected?
High break-even points are typically caused by: high fixed costs relative to contribution margin, low prices relative to variable costs, or a combination. The fastest path to reducing break-even is identifying which fixed costs can be reduced or which variable costs can be cut — then re-running the calculation to see the new threshold.
Data Sources
Accuracy & Verification
Break-even formulas (Fixed Costs ÷ Contribution Margin) are standard cost accounting methodology per Generally Accepted Accounting Principles (GAAP). Break-even ROAS formula (1 ÷ Gross Margin %) is industry-standard digital marketing calculation. The tool uses simplified linear cost modeling — it does not account for stepped fixed costs, taxes, or depreciation, as noted in the disclaimer panel. Last verified: April 2026.
This tool provides estimates for informational purposes only. Results do not constitute financial, accounting, tax, or investment advice. Actual break-even depends on real-world cost structures that may include stepped costs, volume discounts, seasonal variation, and factors not captured by a simplified linear model.
