Break-Even Calculator for Small Business: Find Your Number
The break-even point, sometimes called the break-even quantity, is the number of units a business must sell for total revenue to exactly equal total costs, resulting in zero profit and zero loss. Below that number, every sale moves you toward zero. Above it, every sale starts building real profit.
This guide walks through the break-even formula, what it actually means, and the three levers you can pull when the result doesn't look right.
Break-Even Formula
Use the formula below to find your break-even point in units. A worked example using real numbers follows in the next section.
What the Break-Even Formula Actually Is
The math behind break-even analysis is straightforward. You need to know three numbers before you start.
Fixed costs: Expenses you pay regardless of how much you sell. Rent, software subscriptions, insurance, and annual fees all count here.
Selling price per unit: What one customer pays for one product.
Variable cost per unit: What it costs you to make or acquire one unit. Materials, packaging, shipping supplies, marketplace fees, and payment processing all belong here.
Once you have those three numbers, the formula is:
The bottom half of that equation, selling price minus variable cost, has a name: contribution margin per unit. It represents how much revenue from each sale is actually available to cover your fixed costs. Once you have sold enough units for that contribution to equal your total fixed costs, you break even. Every unit after that contributes to profit.
Not sure if your selling price actually covers what it costs you to make?
Getting the fixed costs, variable costs, and selling price lined up correctly is where most handmade sellers get stuck. The Batchforja newsletter breaks down exactly this kind of math in plain terms, so you can run the numbers with confidence.

Say you make soy candles and sell them on Etsy and your own Shopify store. Here are your numbers for a given month.
Input | Amount |
|---|---|
Monthly fixed costs (Shopify plan, labels, studio rent share) | $320 |
Selling price per candle | $24 |
Variable cost per candle (wax, wicks, jars, dye, fragrance, packaging, Etsy fees) | $9.50 |
Contribution margin per unit: $24.00 - $9.50 = $14.50
You need to sell 23 candles in a month to cover your fixed costs. Because 22 candles only cover $319 of your $320 fixed costs, the 23rd candle sold is the one that pushes you into profit — and every candle after that adds $14.50 to your bottom line.
That number is useful by itself. But the more important question is what happens when your inputs change.
What to Do When Your Break-Even Number Looks Wrong
Most people calculate their break-even point, look at the result, and feel either relieved or worried without knowing what to do next. The calculator gives you a number. What you do with it is the actual work.
There are only three levers available to you: your price, your variable costs, and your fixed costs. Every break-even improvement runs through one of them.
Lever 1: Raise Your Price
This is the highest-impact lever available to most small makers. Raising your selling price increases the contribution margin on every unit without changing your cost structure at all.
Using the candle example: if you raise your price from $24 to $28, your contribution margin becomes $18.50 instead of $14.50. Your break-even point drops from 23 units to 18 units. You need five fewer sales per month to cover your fixed costs.
Most handmade sellers underprice. If you have never done a formal pricing review, the guide on how to price handmade soap walks through a framework that applies to nearly any physical product, not just soap.
Lever 2: Reduce Variable Costs
Variable cost reductions improve your contribution margin on every unit sold. Buying materials in bulk, switching suppliers, or simplifying your packaging all lower the variable cost per unit.
If you cut your candle variable cost from $9.50 to $8.00 by buying wax in larger quantities, your contribution margin rises from $14.50 to $16.00. Break-even drops from 23 units to 20 units.
One note of caution: variable cost cuts that reduce product quality tend to follow you into reviews and return rates. The math looks better in the short run and worse over time. Focus on waste reduction and supplier negotiation before touching the product itself.
Lever 3: Reduce Fixed Costs
Fixed costs are harder to move quickly, but they matter. If you are paying for software, subscriptions, or services you are not using fully, cutting them lowers the threshold you have to clear each month.
In the candle example, cutting fixed costs from $320 to $240 drops the break-even point from 23 units to 17 units, without touching price or variable costs at all.
Break-Even vs. Profit: An Important Distinction
Break-even tells you when you stop losing money. It does not tell you when you start making meaningful income. Those are different thresholds, and conflating them is a common mistake for early-stage sellers.
To calculate a profitability target instead of just break-even, add your desired profit to your fixed costs before dividing.
If you want to take home $500 in profit after covering your $320 in fixed costs, your contribution margin must total $820 — enough to cover both fixed costs and your profit target. At $14.50 contribution margin per candle, you need to sell 57 candles, not 23.
That gap between break-even and profitability is where pricing strategy, production volume, and channel decisions actually live. Break-even is just the floor.
For a deeper look at what profit margin looks like across product lines, the profit margin calculator for handmade sellers covers how to read margin percentage alongside raw profit numbers.
Break-Even Across Multiple Products
Most small makers do not sell a single product. They sell five, or fifteen, or fifty. Multi-product break-even analysis adds a layer of complexity because different products contribute different margins.
The simplest approach is to calculate a weighted average contribution margin across your product mix and use that as your per-unit number. But that only works if your sales mix stays roughly consistent.
A more practical approach for handmade sellers is to treat break-even as a revenue target rather than a unit target. Calculate your total fixed costs, then determine what blended average margin you need to cover them.
Where contribution margin ratio = (selling price - variable cost) / selling price.
If your blended contribution margin ratio is 55% (meaning for every $1 in revenue, $0.55 covers fixed costs after variable costs are paid) and your fixed costs are $400/month, you need $727 in monthly revenue to break even, regardless of which products made up that revenue.
This framing is particularly useful when you sell across multiple channels like Etsy, Shopify, and wholesale, because your effective variable costs (and therefore your contribution margin) differ by channel due to fees and shipping structures.
How Channel Fees Change Your Break-Even
Selling on Etsy versus selling on your own site are not equivalent from a break-even standpoint. Etsy charges listing fees, transaction fees, and payment processing fees that come directly out of each sale. Those are variable costs, and they narrow your contribution margin on every Etsy order.
Etsy's total fee load on a typical transaction runs between 8% and 12% of the sale price, depending on whether your shop is enrolled in Offsite Ads and how the order is fulfilled. According to Etsy's published fee schedule (verify current rates, as fees are subject to change), sellers pay a 6.5% transaction fee plus a 3% + $0.25 payment processing fee at minimum, before any optional ad fees.
On your own Shopify store, you replace Etsy fees with Shopify's monthly subscription (fixed cost) and payment processing fees, which are typically around 2.9% + $0.30 per transaction for the basic plan.
That difference matters at the unit level. A candle selling for $24 on Etsy carries roughly $2.73 in platform fees at minimum — a 6.5% transaction fee ($1.56), a 3% + $0.25 payment processing fee ($0.72 + $0.25 = $0.97), plus a $0.20 listing fee — before any Offsite Ads charges. The same candle sold through your own site might carry approximately $1.00 in payment processing. That gap of roughly $1.73 represents an approximate 12% difference in contribution margin on a product with $14.50 baseline contribution.

Break-Even for Production Decisions, Not Just Pricing
Break-even analysis is usually taught as a pricing tool. It is equally useful as a production planning tool, and that use case gets less attention than it deserves.
If you are considering a new product line, a booth at a craft fair, or a wholesale minimum order quantity, break-even analysis is the right first question. Not "will this product be popular" but "how many do I need to move before this makes sense at all."
Craft fair example: Say booth fees, travel, supplies, and your time cost $450 for the day (for example, 8 hours at your $20/hr labor rate (substitute your own rate — see the labor rate guide linked below for how to set this number) = $160, added to $290 in booth and supply costs). Your average product sells for $22 and carries $9 in variable costs. Contribution margin is $13 per unit.
You need to sell 35 units before the day produces any return. Whether that is realistic depends on foot traffic, your product category, and your display. But now you have a concrete target to evaluate against your expectations, rather than a vague hope that the day will be profitable.
The same logic applies to wholesale. If a retailer wants a minimum order of 24 units at 50% of your retail price, run the break-even math on that order specifically. Does the contribution margin at wholesale pricing still cover your variable costs with enough left to be worth the production run? Using the candle example: retail price $24, so wholesale price is $12. Variable cost per unit is $9.50. Contribution margin at wholesale = $12.00 - $9.50 = $2.50 per candle. A 24-unit order generates $60 in contribution margin — enough to cover only $60 of fixed costs. If your monthly fixed costs are $320 and this order represents roughly one-quarter of your monthly production capacity, allocate about $80 in fixed costs to it. At $60 contribution margin, this order does not fully cover its fixed cost share — which is a concrete reason to negotiate a higher minimum or a better wholesale rate. Compare that to your actual fixed cost allocation for the production run to decide if it is worth accepting.
Common Mistakes in Break-Even Calculations
The formula is simple. The inputs are where most people go wrong.
Forgetting Labor in Your Break-Even Calculation
If you do not pay yourself a consistent hourly rate and include it in your variable cost per unit, your break-even number is understated. You might hit break-even on paper while working for effectively nothing per hour.
Labor is the most commonly excluded cost in handmade business pricing. The guide on setting your labor rate for handmade product pricing covers how to calculate an hourly rate that reflects what your time is actually worth.
Misclassifying Costs in Break-Even Analysis
Some costs are neither purely fixed nor purely variable. They are semi-variable: they change in steps as volume increases. Your packaging supplier might charge one rate per unit for orders under 500 and a lower rate above 500. That is a step cost, not a fixed cost.
For most small makers, treating costs as cleanly fixed or variable is accurate enough. But as volume grows, semi-variable costs like production equipment, additional software tiers, or part-time help start to matter more.
Using Gross Revenue Instead of Net Revenue
If you sell on platforms that take fees before depositing funds, make sure your selling price input reflects what you actually receive, not what the customer pays. On Etsy, the customer might pay $24 but you receive closer to $21 after fees. Your break-even math should reflect the $21.
Alternatively, include the full selling price and add all platform fees to your variable cost line. Either approach works as long as you are consistent.
Ignoring Returns and Defects
A small product defect rate or return rate effectively reduces your revenue per unit produced. If 2% of your candles have pour defects and cannot be sold, your effective yield is 98%. Over a large enough production run, that matters in break-even calculations.
For most early-stage sellers, this is a minor consideration. As volume scales, it becomes worth building into the variable cost per unit or into your pricing buffer.
When to Revisit Your Break-Even Point
Break-even is not a one-time calculation. Your costs change, your prices change, and the channels you sell through change. A break-even number you calculated eighteen months ago is probably not accurate today.
There are four reliable triggers for recalculating.
Material costs change: Supplier price increases or bulk purchasing deals directly affect your variable cost per unit.
You add or drop a sales channel: New platform fees or removed fees shift your per-unit economics.
You change your pricing: Any price change affects contribution margin and therefore break-even.
Fixed costs increase or decrease: New software, a studio space, or hired help changes your monthly threshold.
For makers who track their inventory and production costs in a dedicated system, these numbers are always current. For makers still running on spreadsheets, cost changes often go unnoticed until the margin math stops working. The guide on when you have outgrown spreadsheet inventory tracking covers the signs that your tracking method is costing you accuracy.

Key Takeaways
Here is what to remember from this guide on calculating your break-even point as a small business or handmade seller.
Break-even units = fixed costs divided by contribution margin per unit (selling price minus variable cost per unit).
The contribution margin is the number that drives everything. Price increases and variable cost reductions both improve it.
Break-even tells you when you stop losing money. A separate profit target calculation tells you when you start building real income.
Platform fees are variable costs. Selling on Etsy and selling on your own site produce different break-even points for the same product at the same price.
Labor is a variable cost. Leaving it out makes your break-even look lower than it actually is.
Break-even applies to production decisions and event planning, not just product pricing. Any time you commit fixed costs to an uncertain outcome, break-even math belongs in the decision.
Revisit your break-even calculation any time a material input changes: costs, price, fixed expenses, or sales channels.
