ROAS Calculator — Calculate Your Return on Ad Spend
Return on ad spend (ROAS) tells you how much revenue your ads generate for every dollar spent. It is the most direct measure of whether a paid campaign is working. Enter your numbers above to get your ROAS instantly — no spreadsheet, no guesswork. This page also covers the formula, real examples, industry benchmarks, and what your result actually means.
What ROAS Means and Why It Matters
ROAS measures revenue efficiency in paid advertising. A ROAS of 4 means every $1 spent on ads returned $4 in revenue. It is not the same as profit — it only compares revenue to ad spend, not to product costs or overhead. That is why your break-even ROAS matters as much as your actual ROAS.
ROAS is used at the campaign level. You calculate it per campaign, per ad set, or per channel — then shift budget toward whatever produces the highest return.
The ROAS Formula
ROAS = Revenue from Ads ÷ Total Ad Spend
You spent $1,500. Your ads generated $7,500. ROAS = 7,500 ÷ 1,500 = 5.0
To express it as a percentage, multiply by 100. A ROAS of 5 = 500%.
Break-Even ROAS Formula
Break-Even ROAS = 1 ÷ Gross Profit Margin
At 40% margin: 1 ÷ 0.40 = 2.5. Any ROAS below 2.5 loses money after product costs, even when revenue looks positive.
Step-by-Step: How to Calculate ROAS
Step 1 — Get your total ad spend Pull the exact amount spent from your ad platform for the campaign and date range you are measuring.
Step 2 — Get revenue attributed to those ads Use your platform's conversion report or store analytics (Shopify, GA4). Match the same date range.
Step 3 — Divide and compare Revenue ÷ Ad Spend = ROAS. Then compare that number to your break-even ROAS. If it is above — profitable. If it is below — optimize before scaling.
Real-World ROAS Examples
Ecommerce Apparel — Google Shopping Spend: $3,200 | Revenue: $14,400 | Margin: 45% | Break-even ROAS: 2.22 ROAS = 4.5 — Profitable and ready to scale.
Dropshipping Store — Meta Ads Spend: $2,000 | Revenue: $5,600 | Margin: 25% | Break-even ROAS: 4.0 ROAS = 2.8 — Below break-even. Revenue looks positive but the campaign is losing money after product cost.
SaaS Company — Google Search Spend: $8,000 | Revenue: $19,200 | Margin: 80% | Break-even ROAS: 1.25 ROAS = 2.4 — Comfortably profitable. High margins mean less ROAS is needed to profit.
Industry ROAS Benchmarks 2026
| Industry | Average ROAS | Gross Margin | Break-Even ROAS |
|---|---|---|---|
| Ecommerce — Apparel | 3.5x – 5x | 40–55% | 1.8 – 2.5 |
| Dropshipping | 2.5x – 4x | 20–30% | 3.3 – 5.0 |
| Beauty & Personal Care | 3x – 6x | 50–70% | 1.4 – 2.0 |
| Health & Supplements | 3x – 6x | 50–65% | 1.5 – 2.0 |
| Electronics & Tech | 2x – 4x | 10–25% | 4.0 – 10.0 |
| Home & Furniture | 4x – 7x | 35–50% | 2.0 – 2.9 |
| SaaS / Software | 2x – 4x | 70–85% | 1.2 – 1.4 |
| Lead Generation | 2x – 5x | N/A | Use CPA metric |
A ROAS of 4 means nothing without knowing your margin. A dropshipping store at 25% margin barely breaks even at 4x. A beauty brand at 65% margin is highly profitable at 4x.
ROAS vs ROI vs CPA
| Metric | Formula | Use When |
|---|---|---|
| ROAS | Revenue ÷ Ad Spend | Ecommerce, campaign optimization |
| ROI | Net Profit ÷ Investment | Business-level budget decisions |
| CPA | Ad Spend ÷ Conversions | Lead gen, fixed-value conversions |
Use ROAS when conversion values vary — like ecommerce. Use CPA when every conversion is worth the same — like leads or installs. Use ROI monthly to assess overall profitability.

How to Improve ROAS
Tighten audience targeting — broad audiences waste spend on low-intent users. Retarget people who reached checkout but did not convert.
Improve landing page conversion rate — a 1% lift produces more revenue from the same ad spend without changing your bids.
Raise average order value — bundles, upsells, and free shipping thresholds increase revenue per transaction, which lifts ROAS without touching ad spend.
Cut losing ad sets fast — sets that spend 2x your target CPA without hitting ROAS goals should be paused, not left running.
ROAS for Dropshipping
Dropshipping margins typically run 15–30%. At 25% margin, break-even ROAS is 4.0. A ROAS of 3.5 — which looks decent by general standards — is an unprofitable campaign at that margin. Most dropshipping advertisers need a 4x–6x floor before ads actually contribute profit.
Frequently Asked Questions
What does ROAS stand for?
ROAS stands for Return on Ad Spend. It measures how much revenue you earn for every dollar spent on advertising. A ROAS of 5 means $5 in revenue for every $1 in ad spend.
What is a good ROAS?
Anything above your personal break-even ROAS. Calculate yours first: 1 ÷ gross margin. Most ecommerce businesses target 3x to 5x as a general range.
How is ROAS calculated?
Revenue from Ads ÷ Total Ad Spend. Spend $2,000, generate $10,000 — ROAS is 5.
What is a good ROAS for ecommerce?
Between 3x and 5x for most stores. High-margin products can profit at 2x to 3x. Dropshipping and thin-margin products typically need 4x or more.
What is a good ROAS for Google Ads?
Industry average sits between 3x and 5x. Shopping campaigns can reach 6x to 8x. Always set your target based on your own margin, not platform averages.
How do I calculate break-even ROAS?
1 ÷ gross profit margin. At 35% margin, break-even ROAS is 2.86. Below that number, the campaign is losing money even when revenue looks healthy.
Is a higher ROAS always better?
Not always. Very high ROAS usually means very limited reach. Find your profitable floor and push volume within it rather than chasing the highest number.
When should I use CPA instead of ROAS?
Use CPA for fixed-value conversions like leads or installs. Use ROAS when conversion values vary across transactions, as in ecommerce.
