How to Calculate ROAS

ROAS stands for Return on Ad Spend. It measures how much revenue you earn for every dollar spent on advertising. It is one of the most commonly used metrics for evaluating paid media performance across platforms like Google Ads and Meta Ads.

To calculate ROAS, divide the total revenue generated from your ads by the total amount spent on those ads. The result tells you your return per dollar of ad spend in dollars.

Keep in mind that ROAS measures revenue, not profit. A positive ROAS does not automatically mean your campaigns are profitable once product costs, shipping, and fees are accounted for. For profitability analysis, use our Break-Even ROAS Calculator.

ROAS Formula

ROAS = Revenue ÷ Ad Spend
ROAS % = ROAS × 100

If you spent $5,000 on ads and earned $20,000 in revenue, your ROAS is 4.0x (or 400%). That means you generated $4.00 in revenue for every $1.00 in ad spend. This calculator gives you the result in dollars automatically.

ROAS Calculation Examples

Example 1 — Ecommerce Store

Ad Spend $3,000
Revenue $12,000
ROAS 4.00x
ROAS % 400%

For every $1 spent on ads, $4.00 in revenue was generated.

Example 2 — Google Ads Campaign

Ad Spend $10,000
Revenue $25,000
ROAS 2.50x
ROAS % 250%

A 2.5x ROAS means you earned $2.50 in revenue for every $1 you invested in Google Ads. Whether 2.5x is a good result depends entirely on your margins and costs.

Example 3 — Dropshipping Store

Ad Spend $1,500
Revenue $6,000
ROAS 4.00x
ROAS % 400%

For dropshipping businesses, a high ROAS does not always mean strong profits. Product costs, shipping, and platform fees reduce your actual margin. Use the Break-Even ROAS Calculator to see whether your ROAS is truly profitable.

What Is a Good ROAS?

There is no single number that qualifies as a "good" ROAS for every business. The right target depends on your profit margins, cost structure, industry, and campaign goals.

As general guidance: a ROAS of 1.0x means your ad revenue matched your ad spend, but you likely lost money once product costs and overhead are included. Some high-margin businesses can be profitable at 2x. Others — especially in dropshipping or commoditized markets — may need a significantly higher ROAS before they break even on profit.

For Google Ads, ROAS varies considerably by campaign type. Search campaigns tend to produce different results than Shopping or Display campaigns. For Meta Ads (Facebook and Instagram), ROAS typically differs between prospecting and retargeting campaigns.

Rather than chasing a generic benchmark, focus on whether your ROAS exceeds the break-even point for your specific business. To find that number, use our Break-Even ROAS Calculator.

ROAS vs ROI

ROAS and ROI are related but measure different things.

  ROAS ROI
Stands for Return on Ad Spend Return on Investment
Measures Revenue per dollar of ad spend Net profit relative to total investment
Formula Revenue ÷ Ad Spend (Net Profit ÷ Total Cost) × 100%
Scope Ad spend only All costs

Use ROAS to evaluate ad efficiency. Use ROI when you need to account for all business costs and measure actual profitability.

Frequently Asked Questions

How do you calculate ROAS?

Divide your total ad revenue by your total ad spend. For example, $20,000 in revenue from $5,000 in ad spend equals a 4.0x ROAS.

What does 2.5 ROAS mean?

A 2.5x ROAS means you earned $2.50 in revenue for every $1 you spent on advertising. In percentage terms, that is a 250% return on ad spend.

Is 800% ROAS good?

An 800% ROAS (8.0x) means $8 in revenue per $1 of ad spend, which is a strong ratio in most situations. However, whether it translates to real profit depends on your product costs and margins.

What is a good ROAS for Google Ads?

It depends on your business. There is no universal benchmark. The ROAS you need depends on your margins, overhead, and goals. Focus on whether your ROAS covers all your costs, not on hitting an arbitrary number.

What is the difference between ROAS and ROI?

ROAS measures revenue per dollar of ad spend. ROI measures net profit relative to total investment. ROAS is narrower and specific to advertising. ROI is broader and accounts for all costs.

Does high ROAS mean profit?

Not necessarily. ROAS only measures revenue, not profit. You could have a 5x ROAS and still lose money if your product costs, shipping, and fees exceed your margins. Use a break-even calculator to check profitability.
