Free ROAS Calculator

About this tool

ROAS (Return on Ad Spend) is the number that tells you whether your advertising is actually making money. A 4x ROAS means every dollar you put into ads generates four dollars in revenue. Simple. Powerful. And the fastest way to figure out where to put your next marketing dollar.

This calculator goes beyond the basic ROAS formula. It shows you ROI (the actual profit percentage), break-even analysis, and how your campaigns compare to channel-specific benchmarks. The multi-campaign mode lets you compare performance side-by-side so you can shift budget from underperformers to your best channels.

Here's something most advertisers miss: email marketing has a ROAS of $36-42 for every $1 spent — far higher than any paid ad channel. That's because you're reaching people who already know you. Use our email ROI calculator to see the numbers for yourself, and pair paid acquisition with automated email sequences to maximize the lifetime value of every lead you pay for.

Frequently Asked Questions

How do you calculate ROAS?

ROAS = Revenue Generated from Ads / Ad Spend. For example, if you spent $5,000 on Google Ads and generated $20,000 in revenue, your ROAS is 4.0x (or 400%). This means every $1 in ad spend generated $4 in revenue.

What is a good ROAS?

It depends on your channel and margins. For Google Search Ads, 4x+ is considered good. For Facebook/Meta, 3x+ is strong. For email marketing, 36x is the average. Generally, a 4x ROAS is a healthy minimum for most paid ad campaigns — but you need at least 3x to cover product costs and overhead on top of ad spend.

What is the difference between ROAS and ROI?

ROAS measures revenue relative to ad spend (Revenue / Ad Spend). ROI measures profit relative to total investment ((Revenue - Cost) / Cost × 100). A 4x ROAS equals a 300% ROI. ROAS is more commonly used in digital advertising because it focuses specifically on ad efficiency, while ROI is a broader business metric.

What ROAS do I need to break even?

A 1x ROAS means you're breaking even on ad spend alone — but you're likely losing money when you factor in product costs (COGS), shipping, staff, and overhead. Most businesses need at least a 2-3x ROAS to truly break even, depending on their profit margins. If your margins are 50%, you need at least 2x ROAS to cover costs.

Why is email marketing ROAS so much higher than paid ads?

Email reaches people who have already opted in — they know your brand and are predisposed to buy. There's virtually no media cost (you're not paying per impression or click), so even modest revenue from email campaigns generates massive ROAS. The main cost is the email platform itself, which is tiny compared to ad spend.

How do I improve my ROAS?

Two levers: increase revenue per dollar spent or reduce spend per conversion. Tactically: improve ad targeting to reach higher-intent audiences, optimize landing pages for conversion, test ad creative relentlessly, use retargeting to bring back warm visitors, and nurture leads with email instead of paying for them again with ads.

Should I use ROAS or CPA to measure campaign performance?

Use both. ROAS measures how much revenue you generate per dollar (better for revenue-focused campaigns). CPA (Cost Per Acquisition) measures how much you pay per conversion (better for lead generation). If you sell products at different price points, ROAS is more informative because it accounts for revenue differences.

How do I calculate blended ROAS across multiple channels?

Add up total revenue from all channels and divide by total ad spend across all channels. For example: $100,000 revenue from Google + Facebook + Email, divided by $25,000 total ad spend = 4x blended ROAS. This gives you the overall efficiency of your marketing mix.
