Why we built Supademo's marketing ROI calculator
“Marketing teams spend a lot to get a click, then hand the prospect a static page. Porter Metrics saw a 25% lift in engagement after replacing static content with interactive demos. ROI is easier when the page itself does the selling.”
“In our 2026 demos report, 65% of teams rated demos as having high or very high impact on marketing engagement. When the campaign click lands on something interactive, more of the attention you paid for actually translates into product understanding.”

Frequently asked questions
Common questions about marketing ROI, ROAS, CPL, conversion rate, and improving campaign performance with interactive demos.
What is marketing ROI?
Marketing ROI measures the revenue (or gross profit) generated by a marketing investment relative to what was spent. It is most useful as a comparative metric, comparing the ROI of different channels, campaigns, or time periods, rather than as a target number in isolation.
Many teams calculate it on gross profit rather than revenue to reflect actual contribution, because a campaign at 30% margin looks very different from one at 80% margin even with the same top-line number. Use this alongside the CAC calculator to see how marketing efficiency affects acquisition cost.
How do you calculate marketing ROI?
Subtract marketing spend from revenue attributable to marketing, divide by marketing spend, and multiply by 100 to express as a percentage. The hardest part is attribution. Most pipelines touch multiple touchpoints before closing, so pure last-touch or first-touch ROI is a simplification.
Multi-touch attribution models are more accurate but require more instrumentation. For a directional read, this calculator provides a clean baseline using the inputs you have available.
What is ROAS?
ROAS (return on ad spend) is revenue divided by ad spend, expressed as a ratio or multiplier. A ROAS of 4x means you generated $4 in revenue for every $1 spent.
Unlike ROI, ROAS does not subtract the spend before calculating, so it is always higher than ROI for the same campaign. ROAS is most common in paid media contexts where spend-to-revenue traceability is direct; ROI is more appropriate when evaluating total marketing programs that include organic and brand investment.
What is breakeven revenue?
Breakeven revenue is the minimum attributed revenue needed to recover your marketing spend before generating profit. In this calculator it equals your total spend. Any revenue above that number contributes positively to ROI.
Knowing your breakeven is useful for setting minimum performance thresholds for campaigns before you approve additional budget, particularly for paid channels where you can adjust spend in real time.
How is cost per lead calculated?
This calculator divides total marketing spend by the number of leads generated to give you CPL. CPL is a useful efficiency metric but not a proxy for ROI, because lead quality varies enormously by channel and campaign.
A $20 CPL from paid social that closes at 2% is worse than a $200 CPL from a webinar that closes at 15%. Our breakdown of demand generation metrics shows which CPL-adjacent numbers actually predict pipeline quality. Connect CPL to downstream conversion rates and deal sizes to see which lead sources drive ROI.
How is conversion rate calculated?
If you enter both leads and conversions, the calculator divides conversions by leads and shows the result as a percentage. This is the lead-to-customer conversion rate, which is the clearest bridge between marketing volume metrics (leads, CPL) and revenue outcomes.
A high CPL with a high conversion rate often outperforms a low CPL with a low conversion rate. Conversion rate is what determines whether marketing spend translates to customers.
How can interactive demos boost marketing ROI?
Interactive demos embedded on landing pages, in email campaigns, and on comparison pages improve click-to-signup conversion rates by giving prospects a hands-on product experience before they commit. When visitors can explore the product rather than watch a passive video, purchase intent increases because they are self-qualifying in real time.
Supademo customers report a 28% average reduction in CAC, which directly improves marketing ROI by generating the same revenue from lower spend. You can explore campaign use cases at product marketing.
