Marketing ROI Calculator

WHERE THE MONEY ACTUALLY GOES

What is your marketing really returning?

Most businesses know what they spend but not what it earns back. This calculator turns your spend, traffic, conversion rate and average sale value into a clear picture: your current return on ad spend, and how much more revenue a better conversion rate would unlock. No signup, nothing stored.

The "optimized" column applies your selected, illustrative conversion-rate lift to today's traffic and spend. It is a planning model, not a guarantee — real results depend on offer, market, and execution.

How to read it: the “optimized” figures are an illustrative model, not a promise — they apply the conversion-rate lift you select to your current traffic and spend. Real gains depend on your offer, market, and execution. What’s reliable is the shape: a small lift in conversion compounds across every visitor you already pay for.

COMMON QUESTIONS

Marketing ROI, answered

How to read the numbers and what moves them.

What is return on ad spend (ROAS)?

ROAS is revenue divided by what you spent to earn it. A 4× ROAS means every $1 of marketing returned $4 in revenue. It’s a quick gauge of efficiency — but it ignores margin, so pair it with your cost per customer and average sale value, both of which this tool shows.

Where does the “optimized” column come from?

It applies the conversion-rate lift you pick — conservative, typical, or aggressive — to your current traffic and spend, then recomputes customers, revenue, cost per customer and ROAS. It’s a planning model to show the leverage in conversion rate, not a forecast of guaranteed results.

Why focus on conversion rate instead of more traffic?

Because you’ve already paid for the traffic. Lifting the percentage that converts earns more from the same spend, while buying more traffic costs more up front. Conversion-rate optimization — faster pages, clearer offers, better landing pages and follow-up — is usually the cheaper lever.

Is my data stored?

No. The calculation runs entirely in your browser — nothing is sent anywhere unless you choose to email yourself the results. If you do, we get a copy so we can help you take the next step, and that’s it.
