# eCommerce ROAS Calculator | Online Store Return on Ad Spend

Turn ad spend, click cost, conversion rate, and average order value into return on ad spend and profit. Built for Shopify, DTC, and online-store paid media where the sale is the conversion.

## What is eCommerce ROAS?

For an online store, ROAS measures the revenue your ads generate per dollar of ad spend. Because every conversion is an immediate sale, the result maps directly to the revenue figures you see in Shopify and your ad platform.

Unlike B2B, there is no lead-to-close lag — ROAS from a Meta or Google campaign should reconcile (within attribution windows) to the sales channel in your store admin.

## How eCommerce ROAS is Calculated

**ROAS = Revenue ÷ Ad Spend**

Enter your total ad spend, cost per click, store conversion rate, and average order value. The calculator derives clicks, orders, revenue, and ROAS for you. Because the eCommerce tab treats every conversion as an immediate sale, the result maps directly to your Shopify and ad-platform revenue.

## Worked example: Shopify store on Meta

A DTC skincare brand runs Meta prospecting:

- Ad spend: **$15,000**
- CPC: **$1.25** → 12,000 clicks
- Store conversion rate: **2.5%** → 300 orders
- Average order value: **$68** → **$20,400** revenue
- **ROAS = $20,400 ÷ $15,000 = 1.36×**

At 45% gross margin, break-even ROAS = 1 ÷ 0.45 = **2.22×** — this campaign loses money on a margin basis despite generating sales. The fix is margin, conversion rate, or AOV — not blindly chasing a 4× industry average.

## ROAS benchmarks by ecommerce vertical (2025)

| Vertical | Median ROAS | Source |
| --- | --- | --- |
| Health & Supplements | 5.7× | TrueProfit / Varos DTC benchmarks |
| Home & Garden | 5.5× | EcomHint 2025 vertical compilation |
| Beauty & Cosmetics | 3.25× | EcomHint 2025 |
| General ecommerce | 2.87× | EcomHint 2025 platform average |
| Electronics | 2.5× | WordStream / LocaliQ 2024 |

## Methodology & sources

Vertical medians are compiled from DTC operator reports (2025). Compare each row to your break-even ROAS — a 5.7× supplement median is meaningless at 20% gross margin.

## ROAS benchmarks by ad platform (eCommerce)

| Platform | Typical ROAS range | Notes |
| --- | --- | --- |
| Meta (prospecting) | 2.0× – 4.0× | EcomHint avg ~2.2× |
| Meta (retargeting) | 3.5× – 6.0× | EcomHint retargeting ~3.61× |
| Google Shopping | 3.0× – 8.0× | High purchase intent |
| TikTok Shop / TikTok ads | 1.4× – 3.0× | EcomHint avg ~1.4× |
| Google Search (brand) | 6.0× – 12.0× | Often inflated — check incrementality |

## How to calculate ROAS for Shopify

1. **Shopify Admin** → Analytics → Marketing → note channel spend and attributed sales (match your attribution window).
2. **Meta Ads Manager** → Purchase conversion value for the same date range and attribution window (1-day click vs 7-day click matters).
3. Enter spend and revenue in this calculator; add **gross margin** on the [Target ROAS Calculator](/resources/tools/calculators/target-roas-calculator.md) to check break-even.
4. Compare realized ROAS to the vertical row above — not a generic "4× is good" rule.

## Shopify vs Meta ROAS discrepancy

Platform-reported ROAS often differs from Shopify by **20–40%** when attribution windows, view-through conversions, or duplicate pixel fires diverge. Use **MER** (total revenue ÷ total marketing spend) for strategic truth and per-campaign ROAS for tactical decisions. See the [MER Calculator](/resources/tools/calculators/mer-calculator.md).

## Common mistakes

1. **Treating Meta ROAS as Shopify revenue.** Different attribution windows create false confidence.
2. **Blending prospecting and retargeting ROAS.** Retargeting inflates the blended number.
3. **Ignoring returns and refunds** in revenue — net revenue lowers realized ROAS.
4. **Using industry 4× as target** when 30% margins need 3.33× just to break even.
5. **Scaling on platform ROAS while MER flatlines** — classic attribution overlap symptom.

## How to improve eCommerce ROAS

1. Optimize product landing pages and checkout conversion rate.
2. Increase AOV with bundles, upsells, and free-shipping thresholds.
3. Negative keywords and audience exclusions on paid search and social.
4. Separate prospecting vs retargeting reporting and budgets.
5. Refresh creative before raising bids — CPM inflation is a ROAS killer.
6. Run incrementality holdouts before doubling budget on "winning" campaigns.

## Frequently Asked Questions

### What is a good ROAS for an online store?
A common rule of thumb is a 3.0–4.0 ROAS for established eCommerce, but the only number that matters is your break-even ROAS, which is set by your gross margin (break-even ROAS = 1 ÷ margin). A store with thin 30% margins needs a much higher ROAS to profit than one selling 70%-margin goods.

### How do I calculate ROAS for my Shopify store?
Enter your total ad spend, cost per click, store conversion rate, and average order value. The calculator derives clicks, orders, revenue, and ROAS. Because the eCommerce tab treats every conversion as an immediate sale, the result maps directly to your Shopify and ad-platform revenue.

### What ROAS should I target for Facebook ads for Shopify?
Start from break-even ROAS (1 ÷ margin), add 10–20% for prospecting volume, then benchmark against EcomHint's ~2.2× Meta prospecting average for general ecommerce — not as a target, but as a sanity check. Retargeting can sustainably run higher (3.5×+).

### Should I use ROAS or MER for my store?
ROAS measures a single campaign or channel; MER (Marketing Efficiency Ratio) measures total revenue against total marketing spend. As attribution degrades, many DTC brands steer by blended MER for the truth and use per-campaign ROAS for tactical decisions.
