What is marketing ROI?

Marketing ROI (return on investment) measures how much revenue — or profit — your marketing generates compared to what you spent to get it. It's the single clearest way to know whether a channel, campaign, or agency is actually making you money or quietly draining it.

ROI (%) = (Revenue − Marketing Cost) ÷ Marketing Cost × 100

A closely related number is ROAS (return on ad spend), which is simply Revenue ÷ Spend. A 3.0x ROAS means every $1 spent brought back $3 in revenue. ROI subtracts the cost first, so the same scenario is a 200% ROI.

How to calculate your ROI (worked example)

Say you invest $3,000/month in marketing and it produces 50 leads. You close 30% of them — that's 15 jobs. Your average sale is $600:

Revenue = 15 jobs × $600 = $9,000
ROAS = $9,000 ÷ $3,000 = 3.0x
ROI = ($9,000 − $3,000) ÷ $3,000 × 100 = 200%
Cost per lead = $3,000 ÷ 50 = $60
Cost per booked job = $3,000 ÷ 15 = $200

Change any input in the calculator above and every number updates instantly.

What is a good marketing ROI?

A common benchmark is a 5:1 revenue-to-cost ratio (400% ROI) for a strong program, with roughly 2:1 (100% ROI) being the break-even-plus floor once you factor in the cost of delivering the work. But "good" depends on your margins: a business with 60% margins can thrive at a lower ROAS than one running on 15% margins. That's why the calculator includes an optional profit-margin field — revenue ROI and profit ROI can tell very different stories.

Questions

ROI calculator FAQ

What's the difference between ROI and ROAS?

ROAS is revenue divided by spend (a 3.0x means $3 back for every $1 in). ROI subtracts the cost first and shows it as a percentage, so the same case is 200%. ROAS is quick; ROI reflects the actual gain.

Should I use revenue or profit for ROI?

Both are useful. Revenue ROI shows top-line efficiency; profit ROI (using your margin) shows what actually hits your bank account. Enter your margin in the optional field to see net profit per month.

What should I include in "marketing investment"?

Include everything you spend to generate the leads you're measuring: ad spend, agency or management fees, tools, and content costs. The more complete the input, the more honest the ROI.

Is my data saved or shared?

No. The calculator runs entirely in your browser. Nothing you type is sent anywhere, stored, or shared.

My ROI looks low — what now?

Usually the fix isn't more spend — it's a higher close rate, better lead quality, or faster follow-up. That's exactly what we help with. Book a free strategy call and we'll show you where the leaks are.
