Return on Ad Spend (ROAS) Calculator for Marketing

Track how effectively your ad budget is turning into revenue.

Whether you're running paid search, social media ads, or display campaigns, understanding ROAS helps you quickly assess what's working, and what isn't.

What is ROAS in Marketing?

Return on Ad Spend (ROAS) is a marketing metric that tells you how much revenue you're generating for every dollar spent on advertising. It’s one of the simplest and most critical indicators of paid media performance.

For marketers, ROAS provides a direct view of ad efficiency. A high ROAS means you're earning more than you spend; a low ROAS signals it's time to optimise.

ROAS Formula

To calculate ROAS:

ROAS = Revenue from Ads / Ad Spend x 100

For example, if you spend $2,000 on a Facebook campaign and generate $10,000 in revenue, your ROAS would be:

$10,000 / $2,000 x 100 = 500%

This means you’re earning $5 for every $1 spent on ads.

Why ROAS Matters for Marketers

• Clarity: ROAS tells you exactly which campaigns are delivering returns.

• Agility: Quickly cut underperforming ads and scale top performers.

• Budget control: Maximise your ROI by allocating spend based on real outcomes.

Examples of ROAS in Marketing

Example 1: Google Ads Campaign
You spend $1,000 and generate $4,000 in revenue.
ROAS = $4,000 / $1,000 x 100 = 400%

Example 2: Meta Ads Campaign
You spend $3,000 and generate $18,000.
ROAS = $18,000 / $3,000 x 100 = 600% (a benchmark result)

Example 3: LinkedIn Sponsored Content
You spend $5,000 and generate $3,000.
ROAS = $3,000 / $5,000 x 100 = 60% (indicates poor return – time to revise strategy).

What’s a Good ROAS?

A ROAS of 400–600% is often considered strong for digital campaigns. However, what's "good" depends on your industry, profit margins, and sales cycle.

For example:

• eCommerce brands may target 400–800% ROAS.

• B2B service providers may focus on fewer, higher-value leads with longer-term ROI.

Use ROAS as a baseline, but always interpret it alongside profit margins and customer lifetime value (LTV).

Limitations of ROAS

ROAS is helpful, but it doesn’t:

• Account for operating costs or profit margins

• Consider brand awareness or long-term value

• Reflect attribution complexity in multi-touch campaigns

That's why it's best used alongside ROI, CAC, and LTV.

FAQs

What is a good ROAS benchmark?
600% is a strong result for many digital campaigns, but this varies based on costs and margins.

Can ROAS be negative?
ROAS can't be negative, but it can be below 100%—meaning you're spending more than you're earning.

How is ROAS different from ROI?
ROAS looks only at revenue vs ad spend. ROI accounts for all costs and gives a profit-based view.

Does ROAS account for long-term value?
No. ROAS is a snapshot. Pair it with LTV and retention metrics for a bigger picture.
