What is a Return on Ad Spend Calculator?

A Return on Ad Spend (ROAS) Calculator is a tool that digital marketing professionals and businesses use to determine how much value they’re getting out of their marketing and ad campaigns.

With a ROAS calculator, people can quickly compare the true cost of different ad campaigns and find out which campaigns perform the best and which ones are not really worth the cost.

If you offer any kind of digital marketing services, you’ll need a Return on Ad Spend Calculator on your website so your customers can easily visualize how much revenue they can get out of the conversions your campaigns generate.

How to Calculate Return on Ad Spend

The basic formula used to calculate returns on ad spending is not very complicated. You just need to get the total revenue or sales you generated from a campaign and divide that by the cost of the ad campaign. Multiply the resulting number by 100% to make it easier to read and more understandable when you include it in reports.

Return on Ad Spend (ROAS) = (Total Revenue from Campaign ÷ Cost of Ad Campaign) x 100%


You spent $3,000 on PPC ads or sponsored posts for a week wherein you realized $12,000 in total revenue.

($12,000 ÷ $3,000) x 100% = 400%

Your ROAS for the week comes out to 400%.

ROAS values are usually calculated within a specific time period. Some businesses want to see their ROAS performance metrics on a weekly basis while others prefer monthly calculations. A lot of it depends on how long an ad campaign is used. Using a shorter time period also makes it easier to identify which specific campaigns are responsible for the changes in your revenue numbers — especially if you use multiple ad and marketing campaigns at any given time.

Depending on the ad platform you’re using, you can usually track down which ads or campaigns are responsible for individual sales. This allows you to get a more accurate ROAS calculation because you can directly compare the ad cost to the conversions it was able to generate. Otherwise, you can also subtract your average revenue numbers from the revenue you get when running a new campaign to estimate how much sales growth the ads/campaign actually produced.

It is normal to see inconsistency in your ROAS data. You may get 400% ROAS one week, but only see 200% in the following week, so it’s important to run the numbers regularly and consistently to get a true picture of how cost effective your ad spending really is.

Since the ad campaign is at the beginning of the funnel and revenue is usually one of the later funnel-steps, there is a whole journey of funnel steps between the ad and revenue (e.g. click-through-rate on your website, sign-ups, activation rate, and buy decision). Take this into account when evaluating your ROAS.

What is Considered a Good Return on Ad Spend?

The rule of thumb for an acceptable ROAS is $3 to $4 in sales for every $1 in ad spend, which translates to a ROAS of 300% to 400%. Of course, this isn’t a rule that’s set in stone and varies widely from one company to another.

A ROAS of 100% and below is actually a net loss because if you spend $1 in ads to generate $1 in sales, your revenue is only paying for the cost of advertising and you’re not making any money from the actual product or service that you’re offering.

If you have very thin profit margins, you need to target a much higher ROAS in order to improve your bottom line. It’s important to remember that ad spend also eats up some of your profits, so even a 400% ROAS doesn’t guarantee that you’ll see a significant bump in net profits.


ROAS is not a good indicator of income because it doesn’t account for your operating expenses or your profit margins. ROAS is completely separate from ROI or Return on Investment because it only measures the relative performance of ad campaigns based on the sales or leads they’ve generated.

Ad campaigns are part of your marketing budget which is part of your operating expenses. If you spend too much on ads, your operating expenses also increase, which negatively affects your profit margins . But if you concentrate on continuously improving and maximizing your ROAS, you can also get much better ROI over the long term.
