What Is a Good ROAS for E-commerce? Benchmarks for Facebook, TikTok & More

What is a good ROAS for ecommerce? It’s a critical question, and in 2025, there’s no one-size-fits-all answer.

With ad costs rising and attribution becoming less reliable, return on ad spend (ROAS) remains one of the most closely watched metrics for marketing teams. According to ProfitMetrics, average ROAS has dipped 4.3% year over year, putting pressure on every ad dollar.

This guide breaks down what ROAS is, where it still matters, where it falls short, and what “good” looks like across platforms, from Meta to TikTok to Google. You’ll also get practical tips for hitting and improving your targets in a tougher, more cost-sensitive market.

TL;DR

• ROAS = revenue per ad dollar spent.
• “Good” ecommerce ROAS is typically 4-6×, but varies by context.
• 2025 benchmarks: Meta 2.2×, TikTok 1.4×, Google 4.5×.
• Key factors: margins, LTV, growth stage, market saturation.
• Boost ROAS with creative testing, targeting, and platform-native tools.

What is ROAS & How to Calculate It

Return on ad spend (ROAS) tells you how much revenue your ads generate for every dollar spent. It’s a core metric for understanding ad performance. Simple to calculate, but critical to get right.

The formula is straightforward:
ROAS = (Ad-attributed revenue ÷ Ad cost)

Spend $10,000 and earn $45,000 in sales? That’s a ROAS of 4.5×. The result can also be expressed as a percentage – in this case, 450%.

But don’t confuse ROAS with ROI. ROAS focuses purely on revenue generated from ads, not profit after costs. As Google explains, it’s about conversion value per dollar spent, not your net return.

As your strategy matures, ROAS becomes more than just a reporting metric. Platforms like Google Ads even offer target ROAS bidding, letting algorithms adjust bids in real time to hit your revenue goals.

Why ROAS Matters for Ecommerce Profitability

ROAS isn’t just another metric – it’s a profitability checkpoint. It tells you which campaigns are pulling their weight and which are burning the budget.

In fact, ecommerce retailers that leveraged advanced ROAS analysis boosted marketing efficiency by 18%, according to a Harvard-cited study. That’s a real performance impact from simply understanding what drives returns.

But with ad tracking becoming harder post-iOS 14 and customer acquisition costs rising, many brands are seeing falling returns on familiar platforms. 

Even as more teams pivot to broader metrics like Marketing Efficiency Ratio (MER), ROAS remains a top KPI for ecommerce marketers in 2025.

Just keep in mind: ROAS should always be evaluated in context. If a campaign’s goal isn’t direct sales, like top-of-funnel awareness or list building, then a low ROAS doesn’t mean failure. Measuring ROAS at the campaign level helps clarify which efforts are revenue-driven and which are supporting longer-term growth.

Bottom line: MER gives the big-picture view, but ROAS still drives tactical ad decisions.

What is a Good ROAS for Ecommerce?

So, what qualifies as “good” when it comes to ROAS? It depends on your product, margins, and growth goals, but most ecommerce brands aim for 4-6× as a healthy baseline.

According to Ziggy Agency, ecommerce brands typically target 4-6×, while B2B tech companies may settle for 3-5× and SaaS for 3-4×. Enterprise brands often accept 2-3× due to scale.

Shopify calls 4× an “ideal” starting point for profitable scaling. But that number is getting harder to hit. The ProfitMetrics index shows average ROAS dipping 4% YoY in 2025, largely due to rising media costs and increased competition.

Key takeaway: Don’t chase one magic number. Benchmark against your vertical, stage, and margin profile to find your true ROAS sweet spot.

Platform Benchmarks (April 2025)

ROAS benchmarks vary widely by platform. Knowing the latest numbers helps you set realistic expectations and optimize smarter.

Facebook/Meta Ads

The median ROAS sits at 2.19×, with retargeting campaigns hitting 3.61×. That makes Meta a strong bet for re-engagement, even as acquisition costs climb.

TikTok Ads

TikTok’s overall median ROAS is lower at 1.41×, but when brands use “Value” optimization, that number jumps to 2.25×. It’s proof that strategy matters more than spend.

Google Ads (Search)

Search campaigns lead with a 4.52× median ROAS across 5,000+ advertisers, making it the most efficient of the big three channels.

Google Shopping (by vertical)

ROAS can swing dramatically by product category: Electronics ads average ~6×, while Fashion comes in closer to 3.5×.

These medians aren’t targets, they’re baselines. Your goals should flex based on campaign type, vertical, and funnel stage.

Factors That Change “Good” ROAS

There’s no one-size-fits-all ROAS target. What’s “good” depends heavily on your business model, growth phase, and even platform shifts.

1. Margins and LTV

Brands with high margins or strong lifetime value (LTV) (like subscriptions) can scale at lower ROAS. Low-margin DTC brands, on the other hand, often need 5×+ to stay profitable.

2. Growth Stage

Early-stage ecommerce brands typically aim for 6× or more until they recover CAC quickly enough to reinvest. That’s because early ROAS must fund future scale.

3. Attribution Loss

Post-iOS 14, many marketers now pair ROAS with broader metrics like MER to offset attribution gaps. As Agital puts it, smart teams use both to track efficiency and payback.

4. Market Saturation

The ProfitMetrics index shows a 4% YoY drop in average ROAS, reflecting rising ad competition and auction pressure.

These medians aren’t targets — they’re baselines. Your goals should flex based on campaign type, vertical, and funnel stage.

Tactics to Improve ROAS

Raising ROAS isn’t about throwing more budget at ads, it’s about smarter creative, tighter targeting, and faster iteration.

Test and iterate creatives relentlessly

Meta’s Performance 5 framework recommends constant micro-iteration. Even small tweaks to your best-performing ads can revive performance and lift ROAS.

Use high-volume creative testing

Otter.ai scaled up testing and saw a +65% boost in CVR and higher ROAS, according to this Primer case study. The takeaway? Volume and velocity beat perfect creative.

Try platform-native formats

Centrepoint ran TikTok Video Shopping Ads with targeted iOS spend and saw +35% revenue on just +17% budget. Native formats with built-in optimization features can punch above their weight.

Leverage automation tools

Features like Meta’s Dynamic Creative auto-combine assets to find top-performing combinations. Boosting efficiency without more manual work.

Summary & Next Steps

A “good” ROAS is a moving target. Benchmarks like 4-6× offer a helpful starting point, but real success depends on your margins, product category, and growth stage.

To stay profitable, benchmark against both industry averages and platform medians, then fine-tune based on your unique unit economics.
