📈 Why break-even ROAS matters
ROAS counts revenue, not profit. Judge Actual ROAS against Break-even ROAS on the same card.
Benchmark, guidance only: no universal “good ROAS” — compare to break-even.

📅 Monthly projection, target price & break-even price
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 | $1,418.00 | $25.92 | $15.24 |
| 🎨 Etsy | $1,172.00 | $29.60 | $16.52 |
| 📦 Amazon FBA | $667.00 | $40.16 | $21.26 |
Monthly net = net profit per order × orders per month. 40% price = price for 40% gross margin before ads (approximate, as higher price raises percentage fees). Break-even price = profit $0.

📊 How it works
Follow the money, step by step:
1💰 Revenue — Price + shipping charged
2➖ Product cost
3➖ Shipping cost
4➖ Platform fee
5➖ Ad spend
6✅ Net profit
Then check your ads:
1Net profit + ad spend = Gross profit
2Gross profit ÷ Revenue = Margin %
31 ÷ Margin % = Break-even ROAS
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 with $5.00 ad spend, visual split:
🟧 Cost $14.50 (41.4%) 🟦 Fee $1.31 (3.7%) 🟣 Ad $5.00 (14.3%) 🟩 Net $14.18 (40.5%) — Total $34.99 (percentages rounded)
ROAS rule, visual: ❌ Below break-even (e.g. 1.82x for this Shopify example) = losing money on ads | ✅ Above break-even = profitable ads.

- Net profit = price + shipping charged − product cost − shipping cost − platform fee − ad spend. Gross profit before ads = net profit + ad spend. Margin % = gross profit ÷ revenue. Break-even ROAS = 1 ÷ margin %. Actual ROAS = revenue ÷ ad spend, when ad spend > 0.
- Shopify Payments (Basic): 2.9% × (price + shipping charged) + $0.30. Monthly plans $39/$105/$399 and the 2% third-party gateway fee are not in per-order profit.
- Etsy: $0.20 + 6.5% + 3% + $0.25 = 9.5% × (price + shipping charged) + $0.45, before Offsite Ads (15% under $10k/365 days, 12% at $10k+, capped $100, excluded from v1).
- Amazon FBA: referral 15% in most categories (8% electronics, 17% clothing above $20, 20% jewelry, 45% device accessories) × (price + shipping charged, excluding tax) + manual FBA fee. Default $3.57 = $3.45 + $0.12 surcharge (3.5%, since 17 Apr 2026). Peak 15 Oct 2026–14 Jan 2027 ~$0.21. Storage/inbound/aged-inventory surcharges excluded.
- Locked test case: $34.99 / $14.50, no shipping/ads → Shopify $19.18, Etsy $16.72, Amazon $11.67 (peak $11.46). Fees checked 29 Oct 2026.
❓ Frequently asked questions
Tap a question to see the answer.
🧮 What is a seller profit calculator?
A seller profit calculator shows what you actually keep after product cost, shipping, platform fees and ad spend — not just your selling price.
📈 What is break-even ROAS?
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.
🎯 What is Max CAC?
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.
💰 What is Actual ROAS?
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.
🎨 How are Etsy fees calculated?
In this calculator: $0.20 listing + 6.5% transaction + 3% + $0.25 payment processing, before Offsite Ads.
📦 How are Amazon FBA fees calculated?
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.
🔑 Do I need an account to use this calculator?
No. It is free, with no login and no signup, and all calculations run in your browser.
⚠️ Why can a 'good-looking' ROAS still lose money?
Because ROAS is revenue divided by ad spend. A 2x ROAS on a 33% margin product is below its 3.00x break-even, so every order loses money despite the 2x headline.
🔍 What is the difference between break-even ROAS, Actual ROAS and Max CAC?
Break-even ROAS is the hurdle (1 ÷ margin %). Actual ROAS is what you got (revenue ÷ ad spend). Max CAC is the most you can spend per order before losing money, which is gross profit before ads.
📋 Worked example — the same ad spend, two different answers
Start from the locked numbers (price $34.99, cost $14.50, no shipping) and add $5.00 ad spend per order.
Shopify: gross profit $19.18, break-even ROAS 1.82x, Max CAC $19.18, net profit $14.18. Actual ROAS = $34.99 ÷ $5.00 = 7.00x, above 1.82x, so ads are profitable on Shopify at that spend. Amazon: gross profit $11.67, break-even ROAS 3.00x, net profit $6.67 — also above break-even, but with far less headroom. Raise ad spend to $12.00 and Shopify still nets $7.18, while Amazon nets −$0.33.
❓ ROAS questions
Why can a 'good-looking' ROAS still lose money? Because ROAS is revenue divided by ad spend. A 2x ROAS on a 33% margin product is below its 3.00x break-even, so every order loses money despite the 2x headline.
What is the difference between break-even ROAS, Actual ROAS and Max CAC? Break-even ROAS is the hurdle (1 ÷ margin %). Actual ROAS is what you got (revenue ÷ ad spend). Max CAC is the most you can spend per order before losing money, which is gross profit before ads.
📖 Methodology, in short
Net profit = price + shipping charged − product cost − shipping cost − platform fee − ad spend. Gross margin % = gross profit before ads ÷ revenue. Break-even ROAS = 1 ÷ gross margin %. Max CAC = gross profit before ads. Amazon referral is on price + shipping charged (excluding tax), updated 28 Oct 2026. Full fee table, diagram and launch checklist are on the home page: Methodology. Fees are web-search findings from 27–28 Oct 2026, not official-page checks — re-check against official Shopify, Etsy and Amazon pages and date-stamp before launch.
