What is a good ROAS for an eCommerce brand?

A good return on ad spend depends entirely on your margin. A brand with 70 percent gross margin can be profitable at 2x ROAS, while one at 30 percent margin needs roughly 4x to break even. The useful benchmark is your break-even ROAS, calculated from gross margin, not an industry average.

  • Break-even ROAS equals 1 divided by gross margin percentage
  • Blended ROAS across all channels reflects reality better than platform-reported ROAS
  • Repeat purchase rate usually determines whether a brand can scale profitably
  • Contribution margin after shipping and returns is the number that matters

The problem

What usually goes wrong in eCommerce and D2C marketing

  • ROAS falls as you scalePerformance that looks excellent on a small budget drops off as spend grows, because the easiest audience runs out.
  • Creative fatigueThe same three ads running for months while cost per purchase drifts steadily upward.
  • Margin ignoredPlatform-reported ROAS looks healthy while shipping, returns and discounts quietly erase the profit.
  • No repeat revenueEvery sale acquired from scratch because the lifecycle email and WhatsApp flows were never built.

Our approach

We work from contribution margin backwards.

Before touching the ad account we calculate what a customer is genuinely worth after shipping, returns, discounts and payment fees. That sets the true break-even, and every decision after it is made against that number rather than a platform dashboard.

  1. Model the economicsGross margin, shipping, returns and repeat rate turned into a break-even target.
  2. Fix measurementServer-side events and a clean product feed so the data can be trusted.
  3. Scale creativeA continuous pipeline of new angles feeding the algorithm fresh material.
  4. Own retentionLifecycle flows that make the second purchase cheaper than the first.

FAQ

ECommerce marketing agency: questions people ask

Tell us about your business and we'll show you where enquiries are being lost.

How much should an eCommerce brand spend on marketing?

Set the budget from your own numbers rather than a percentage rule: gross margin, average order value and what a customer is worth over time decide how much you can pay per order. Brands with strong repeat purchase can afford more per new customer than one-time-purchase brands. We work out a break-even ROAS before setting any budget.

How do I market my Shopify store?

Start with tracking: Shopify connected to Google Ads, Meta and Google Analytics with purchase values. Then run Meta ads for discovery, Google Shopping and search for people looking for your products, email and WhatsApp flows for abandoned carts and repeat orders, and SEO for collection and product pages. Judge each channel on revenue, not clicks.

What are the best eCommerce marketing strategies?

Profitable brands usually combine a clear offer and strong product pages, Meta ads with frequent creative testing, Google Shopping and search, retention through email and WhatsApp, and reviews on every product. The measure that matters most is profit after ad spend and returns, not revenue alone.

What monthly ad budget do we need?

Enough to test several creative angles and give the platforms conversion data to learn from. The right figure depends on your price point and margin, so we work it out with you during the free growth audit.

Can you improve our repeat purchase rate?

Yes, and it is usually where the fastest margin improvement sits. Post-purchase email and WhatsApp flows, replenishment timing and a considered subscription or bundle offer typically move repeat rate more than any ad change.

How do you handle returns in the reporting?

We report net revenue after returns wherever the platform data allows it. A 4x ROAS on a category with 30% returns is really 2.8x, and pretending otherwise leads to scaling something unprofitable.
