Shopify Break-Even Calculator: Find Your Store's Profit Point

You can do six figures in revenue and still lose money every single month, and most store owners only find out after the bank account tells them. A Shopify break-even calculator fixes that blind spot by answering one brutally simple question: how many orders do you need before your store stops bleeding cash and starts earning it? This guide hands you the formula, the cost map, and copy-ready tables so you can calculate your own break-even point in the next 20 minutes, no accounting degree required.

By the end, you'll know your break-even in units and in revenue, you'll understand how ad spend quietly raises that number, and you'll have a short list of levers to lower it. Grab a coffee and your last 30 days of numbers.

What "Break-Even" Actually Means for a Shopify Store

Break-even is the moment your total revenue exactly equals your total costs. Above that line, every extra sale is profit. Below it, every sale is a slow leak.

Break-even is not the same as "profitable." It's the floor you have to clear first. A store that breaks even at 180 orders a month and ships 200 is barely surviving. A store that breaks even at 180 and ships 600 is winning. The number itself is neutral, what matters is how far above it you're operating.

For a Shopify business, break-even has two flavors and you want both:

• Break-even units tells you how many orders (or products) you must sell.
• Break-even revenue tells you the dollar sales figure you must hit.

Why most new owners get this wrong

The classic mistake is treating revenue like profit. A $50 product feels like $50 in your pocket, but after product cost, Shopify's payment fee, shipping, and a slice of your ad spend, you might keep $12. Calculate break-even on the $50 and you'll think you're safe at 100 sales. Calculate it on the real $12 of margin and the truth is far less comfortable.

The second mistake is forgetting fixed costs entirely. Your Shopify subscription, your apps, and your email tool charge you whether you sell 5 units or 500. Those costs have to be covered before profit starts.

Where the calculator fits in your numbers

Think of break-even as the bridge between your pricing and your survival. If you've already worked out your prices using an ecommerce pricing strategy for new stores, the break-even calculator is what tells you whether those prices actually keep the lights on at your real volume.

The Break-Even Formula (Save This)

Here is the whole engine. Everything else in this article is just feeding numbers into it.

Break-Even Units = Total Fixed Costs ÷ Contribution Margin Per Unit

Contribution Margin Per Unit = Selling Price − Variable Cost Per Unit

Break-Even Revenue = Break-Even Units × Selling Price

That's it. Three lines. The hard part isn't the math, it's correctly sorting your costs into "fixed" and "variable" so the inputs are honest.

What the terms mean in plain English

• Fixed costs don't change with the number of orders. Your Shopify plan is the same whether you sell zero or zero-thousand.
• Variable costs scale with each sale. Make one more product, you pay for one more unit of materials, one more payment fee, one more shipping label.
• Contribution margin is the slice of each sale's price left over after variable costs, the money that "contributes" toward paying off fixed costs and then becoming profit.

A 10-second example

Sell a product for $40. Your variable cost per unit (materials, fees, shipping) is $24. Your contribution margin is $40 − $24 = $16. If your fixed costs are $320/month, you break even at $320 ÷ $16 = 20 units. At unit 21, you're in profit. We'll build a fuller version of this below.

Mapping Your Shopify Fixed Costs

Fixed costs are the easy half because they don't move. Most Shopify stores have a short, predictable list.

The big one is your Shopify subscription. As of 2026, the Basic plan runs $39/month billed monthly (about $29/month if you pay annually), the Grow plan is around $105/month, and Advanced is $399/month, according to Shopify pricing breakdowns published in 2026. If you're unsure which tier you're really paying for, our guide on how much Shopify costs per month walks through every line.

Apps and subscriptions add up fast

The plan is rarely the whole story. A typical store stacks a few paid apps: an email/SMS tool, a reviews app, maybe a subscriptions or upsell app. These are fixed because they bill monthly regardless of sales.

Round to $95/month for clean math. Your list will differ, but the method is identical: anything that bills on a flat schedule goes here.

Don't forget the "hidden" fixed costs

A few fixed costs hide outside Shopify and quietly wreck break-even math when ignored: your accountant or bookkeeping software, a design subscription, stock photography, or a monthly retainer for a freelancer. If it bills on a schedule and doesn't change with order volume, add it to the fixed bucket.

Mapping Your Shopify Variable Costs

Variable costs are the trickier half because they ride along with every order. Get these right and your break-even number will actually be trustworthy.

There are four big variable costs for most Shopify stores:

1. Cost of goods sold (COGS) — what you pay to make or buy the product.
2. Payment processing fees — Shopify's cut of each transaction.
3. Shipping and fulfillment — postage, packaging, pick-and-pack.
4. Per-order ad spend — your marketing cost to win that customer (covered in its own section below).

Nailing down payment fees

This is the cost owners most often forget. With Shopify Payments on the Basic plan in 2026, online credit card transactions cost 2.9% + 30¢ per order, per Shopify's own fee documentation. Higher plans drop the rate (Grow is roughly 2.7% + 30¢, Advanced 2.5% + 30¢). For a $40 order on Basic, that's about $1.46 gone to fees.

Across the wider payments world, Shopify notes the typical card processing fee lands between 1.6% and 3.1%, usually around 2% to 2.5%, so the 2.9% rate is on the higher end and worth optimizing later.

Estimating shipping and COGS honestly

For shipping, use your real average label cost plus packaging, not the cheapest possible rate. If some orders ship free to the customer but you eat the cost, that cost is still variable and still belongs here.

For COGS, use your landed cost: the product plus inbound shipping and any import duties divided across the units. If you're a maker pricing handmade goods, our handmade pricing formula shows how to capture materials and labor so your COGS isn't fantasy.

Worked Example: Calculate Your Break-Even Step by Step

Let's run a full example you can copy line for line. Meet "Brightleaf," a one-product candle store selling at $40.

Step 1 — Total your fixed costs. From the table above: $95/month.

Step 2 — Total your variable cost per unit. From the table above: $21.96.

Step 3 — Find contribution margin per unit.

$40.00 − $21.96 = $18.04 contribution margin

Step 4 — Divide fixed costs by contribution margin.

$95 ÷ $18.04 = 5.27 units, round up to 6 units/month

Step 5 — Find break-even revenue.

6 units × $40 = $240/month in sales

Here's the whole calculation as one copy-ready table:

So far, so good: Brightleaf only needs 6 candles a month to cover its base. But this version ignores advertising, which is where most stores actually live or die. Let's add it.

Reading your contribution margin

Notice the margin is $18.04 on a $40 product, about a 45% contribution margin. That's healthy. The higher this percentage, the fewer units you need and the more resilient you are. If you want to sanity-check your margins more broadly, pair this with a Shopify profit margin calculator so the two numbers agree.

Break-Even With Ad Spend and CAC

The 6-unit answer was true only if customers found Brightleaf for free. Almost nobody does. The moment you run ads, your customer acquisition cost (CAC) becomes a variable cost on every order, and break-even climbs.

In 2026, the average CAC for Shopify stores sits around $35–$65 across all channels, with paid social on the higher end at $45–$85 and email far cheaper at $8–$15, according to 2026 ecommerce acquisition cost benchmarks. Those numbers should make you nervous about a $40 product, and that's the point.

Folding CAC into the formula

Treat CAC like any other variable cost: subtract it from your contribution margin. Say Brightleaf's paid-ad CAC is a modest $12 per customer (helped by repeat buyers and organic traffic mixed in).

New contribution margin = $18.04 − $12.00 = $6.04 per unit

New break-even = $95 ÷ $6.04 = 15.7 units, round up to 16 units/month

That third row is the gut-punch. At a $20 CAC on this product, the contribution margin goes negative, the store loses money on every single paid sale and can never break even no matter how much it sells. This is exactly how stores "scale themselves to death." Average conversion rates for Shopify stores hover around 1.4%, per 2026 conversion benchmarks, so weak conversion quietly pushes CAC up and can flip a winner into that bottom row.

The blended vs. paid CAC trap

Use blended CAC (total marketing spend ÷ total new customers) for your real break-even, not just the cost from your best-performing ad. Founders love quoting their cheapest channel and budgeting on it. Your bank account only cares about the blended number.

Common Mistakes That Break the Calculation

A break-even calculator is only as honest as its inputs. These are the errors that produce a comforting-but-wrong answer.

• Forgetting payment fees. That 2.9% + 30¢ feels tiny until you multiply it across hundreds of orders. It's a variable cost, every time.
• Using best-case shipping. Budgeting your cheapest label instead of your average inflates margin and hides the true break-even.
• Treating ad spend as fixed. A monthly ad budget feels fixed, but it should be expressed per-acquired-customer so it lives in your variable column where it belongs.
• Ignoring returns and discounts. A 10% return rate or a standing 15%-off code shreds margin. Bake an average into your selling price or your variable costs.
• Counting your own salary as zero. If you never pay yourself, "break-even" is a fantasy. Add a modest owner's draw to fixed costs to see the real floor.

The "revenue feels like profit" trap

The single most expensive mistake is celebrating revenue milestones while margin quietly stays negative. Hitting $10k months means nothing if each order loses $2. Always run break-even on contribution margin, never on top-line price.

The "set it and forget it" trap

Your break-even is a snapshot, not a tattoo. App prices rise, ad costs climb, suppliers change quotes. Recalculate every quarter, and any time you add an app or change a price. A number from last March may be dangerously out of date.

How to Lower Your Break-Even Point

Once you know your break-even, the game becomes lowering it so you reach profit faster. There are only two ways: shrink fixed costs or grow contribution margin. Everything below is one of those two.

Grow contribution margin per order

This is the highest-leverage lever because it compounds across every sale.

• Raise prices. Even a $2 increase on Brightleaf's candle lifts margin and drops break-even, often with no measurable hit to conversion. Test it.
• Increase average order value. Bundles, upsells, and free-shipping thresholds spread your fixed costs across bigger orders. A $60 average order breaks even on far fewer transactions than a $40 one.
• Cut COGS. Negotiate supplier pricing at volume, reduce packaging waste, or reorder in larger batches for better unit costs.
• Lower CAC. Shift budget toward your cheapest channels. Email at $8–$15 CAC versus paid social at $45–$85 can rewrite your entire break-even, so invest in owned audiences.

Shrink fixed costs

• Audit your apps. Most stores pay for at least one app they barely use. Cancelling a $20/month app you forgot about directly lowers your break-even.
• Right-size your plan. Don't pay for Advanced features you don't use. Match the plan to your real needs.
• Pay annually. The 25% annual discount on Shopify plans is a permanent fixed-cost reduction if your cash flow allows it.

The fastest wins usually come from margin, not cost-cutting, because there's a floor on how low fixed costs can go but no ceiling on how high you can push margin and order value.

Frequently Asked Questions

What is a good break-even point for a Shopify store?

There's no universal "good" number, because it depends on your costs and price. The better question is how far above break-even you operate. If your break-even is 100 orders and you ship 400, you have a strong, profitable buffer. Aim for a store that sells at least 2–3x its break-even volume so you're not living on the edge.

How do I calculate break-even if I sell many different products?

Use a weighted-average contribution margin. Calculate the contribution margin for each product, weight each by its share of sales, then average them into one blended margin per order. Divide fixed costs by that blended margin. For most small stores, using your average order value and average variable cost gets you close enough to act on.

Should ad spend be in my break-even calculation?

Yes, if you run paid ads. Express it as cost-per-acquired-customer (your CAC) and subtract it from contribution margin, exactly as shown in the ad-spend section above. Leaving ads out produces a break-even number that's far too optimistic and is the leading cause of stores that "look profitable" but aren't.

How often should I recalculate my break-even?

Every quarter at minimum, and immediately whenever you change a price, add or remove an app, switch suppliers, or see your ad costs move. Break-even is a living number. A figure that was accurate three months ago can mislead you today.

Does break-even include my own salary?

It should, if you want the real picture. Add a modest owner's draw to your fixed costs. Otherwise your "break-even" only covers the business's bills while leaving you, the founder, working for free. For deeper cost tracking, see our guide to ecommerce bookkeeping for beginners.
