What is a ROAS Calculator?

ROAS (Return on Ad Spend) measures how much revenue you earn for each dollar you put into ads. If your ROAS is 4x, you're making $4 back for every $1 spent. It's narrower than ROI, which factors in all business costs. ROAS only looks at ad spend versus ad revenue, which is why media buyers and marketers use it to judge whether individual campaigns on Google Ads, Meta, TikTok, or LinkedIn are actually paying off. This calculator gives you your ROAS ratio, tells you if you're above or below break-even, and compares your numbers to industry benchmarks. You don't need to sign up or open a spreadsheet.

How to Use

Enter your total revenue

Add up the revenue from your ad campaigns. Count sales and conversions that came from the ads, not organic traffic.

Enter your ad spend

Put in your total media spend for the same period. This is what you paid the ad platforms, not agency fees or creative costs.

Who Is This For

Performance Marketers

Compare ROAS across Google, Meta, and TikTok to figure out which channel deserves more budget.

Growth Teams

Look at ROAS next to CAC and LTV. A campaign can have strong ROAS but still lose money if acquisition costs are too high overall.

E-commerce Brands

Check which products are worth advertising. If a SKU's ROAS is below break-even, pause the spend.

Agency Account Managers

ROAS is one of the easiest metrics to explain to clients because it directly ties spend to revenue.

Startup Founders

Before you scale ad budgets, check whether early experiments are returning more than they cost.

Freelance Media Buyers

Use ROAS to spot which ad sets and creatives are underperforming across client accounts.

Pro Tips

Break ROAS out by channel. A blended 3x might mean Google is running at 6x while TikTok is at 0.8x.
Know your break-even ROAS. With 60% gross margins, anything under 1.67x loses money.
Compare the same time windows. A 7-day ROAS and a 28-day ROAS use different attribution, so putting them side by side is misleading.
A weak first-purchase ROAS isn't always bad. If your LTV:CAC ratio is healthy, the customer pays off later.
High ROAS at low spend doesn't always scale. A $500/month campaign running 8x may drop to 3x at $5,000/month once you exhaust the easy audience.

What is ROAS?

Return on Ad Spend (ROAS) measures the revenue generated for every dollar spent on advertising. A ROAS of 4x means you earn $4 for every $1 spent on ads.

What is a good ROAS?

A ROAS of 4:1 (or 4x) is generally considered good. However, this varies by industry — e-commerce brands often target 3-5x, while SaaS companies may accept 2-3x due to higher customer lifetime values.

How is ROAS different from ROI?

ROAS measures revenue per ad dollar spent, while ROI (Return on Investment) accounts for all costs including production, overhead, and operational expenses. ROAS is specific to advertising efficiency.

How can I improve my ROAS?

Improve ROAS by optimizing ad targeting, improving landing page conversion rates, increasing average order value, refining ad creatives, and reducing wasted spend on underperforming campaigns.
