Per-order profit on this page is before the monthly plan cost ($39 Basic / $105 Grow / $399 Advanced). A monthly plan is fixed, not per order, so divide it by your orders per month if you want to amortize it. Via Shopify Payments on Basic the fee is 2.9% + $0.30 per order; a third-party gateway adds 2% on Basic.
Benchmark, guidance only: many healthy Shopify direct sellers aim for roughly 20–45% net margin after traffic costs — use it as a sanity check, not a guarantee.
⭐ Shopify is first below because this is the Shopify page — it is also the highest profit overall on these numbers.
🏆 Excellent level — based on 54.8% gross margin on the winning platform.
You are at Excellent level on Shopify. Protect this margin — a small fee or ad increase can drop you a level.

Bars are scaled to the highest profit. 🏆 still marks the highest profit overall.
Max CAC, in plain words: the most you can spend on ads for one order before you start losing money. Example, Shopify above: Max CAC $19.18 — spend $10 on ads for that order and you keep $9.18; spend $19.18 and you break even at $0; spend $20 and you lose $0.82 on that order, even though you made a sale.
Actual ROAS, in plain words: actual revenue divided by actual ad spend, per order. Actual ROAS 10.00x means for every $1 of ad spend, you get $10 of sales revenue — for example $3.50 ad spend and $35.00 revenue. It is revenue, not profit: compare it with Break-even ROAS on the same card. Above break-even = ads are profitable; below break-even = ads lose money, even if ROAS looks high. If ad spend is $0, Actual ROAS shows —, not a number.
Pick one to keep going.
At 100 orders per month, net profit per month (after ad spend, before monthly plan costs) is:
| Platform | Monthly net | 40% price | Break-even price |
|---|---|---|---|
| 🛍️ Shopify | $1,918.00 | $25.92 | $15.24 |
| 🎨 Etsy | $1,672.00 | $29.60 | $16.52 |
| 📦 Amazon FBA | $1,167.00 | $40.16 | $21.26 |
Target price is approximate: raising price also raises percentage fees, so the exact 40% price is slightly higher. Monthly profit = net profit per order × orders per month. 40% price = the selling price that would leave 40% gross margin before ads at your current costs and fees. If it is below your current price, you already beat 40%; if above, that is how high you would need to go to reach 40%. 40% is a healthy-margin example, not a rule. Break-even price = the selling price where profit is $0.
Follow the money, step by step:
Then check your ads:
Max CAC = Gross profit. If ad spend per order is higher than Max CAC, you lose money on that order — even if ROAS looks high.
Example — one $34.99 Shopify sale, visual split:
🟧 Cost $14.50 (41%) 🟦 Fee $1.31 (4%) 🟩 Profit $19.18 (55%) — Total $34.99
ROAS rule, visual: ❌ Below break-even (e.g. 1.82x for this Shopify example) = losing money on ads | ✅ Above break-even = profitable ads.

A seller profit calculator shows what you actually keep after product cost, shipping, platform fees and ad spend — not just your selling price.
Break-even ROAS is 1 ÷ your gross margin %. At 40% margin, break-even ROAS is 2.5x. Below that, you are losing money on ads even if ROAS looks positive.
Max CAC is the most you can spend to get one order — on ads — before you lose money. It equals your gross profit before ads. Example: if gross profit is $19.18, spending $10 per order leaves $9.18, spending $19.18 breaks even, and spending $20 loses $0.82 on that order.
Actual ROAS is your actual revenue divided by your actual ad spend, per order. 10.00x means $10 of sales revenue for every $1 of ad spend — for example $3.50 ad spend and $35.00 revenue. It is revenue, not profit, so always compare it with Break-even ROAS: above break-even is profitable, below break-even loses money even if the number looks high.

Referral fee (15% in most categories; 8% electronics, 17% clothing above $20, 20% jewelry, 45% device accessories, on price + shipping charged, excluding tax) plus a manual FBA fee, default $3.57 for a small-standard item including the 3.5% surcharge. FBA fees vary by size, weight and price band, which is why v1 asks you to enter your fee.

The $39 / $105 / $399 plan is paid monthly whether you sell 10 orders or 1,000, so it cannot be a fair per-order fee on its own. The calculator labels this clearly instead of pretending it is zero.
On Basic it adds 2% of revenue. In the locked example that is $0.70 extra, taking profit from $19.18 to $18.48.
Basic via Shopify Payments (2.9% + $0.30). Grow and Advanced have different Shopify Payments rates, so check the official Shopify pricing page if you sell on those plans.
Try these numbers in the calculator above: selling price $34.99, product cost $14.50, no shipping, no ad spend.
Shopify fee = 2.9% × $34.99 + $0.30 = $1.31. Net profit = $19.18. Gross margin = 54.8%, break-even ROAS = 1.82x, Max CAC = $19.18. With the third-party gateway box checked, the fee becomes $2.01 and profit falls to $18.48.
Why is profit 'before monthly plan cost'? The $39 / $105 / $399 plan is paid monthly whether you sell 10 orders or 1,000, so it cannot be a fair per-order fee on its own. The calculator labels this clearly instead of pretending it is zero.
What changes with a third-party gateway? On Basic it adds 2% of revenue. In the example above that is $0.70 extra, taking profit from $19.18 to $18.48.
Which plan does the 2.9% assume? Basic via Shopify Payments (2.9% + $0.30). Grow and Advanced have different Shopify Payments rates, so re-check the official Shopify pricing page before launch if you sell on those plans.
