Estimate marketplace ROI before you commit
Model illustrative sales lift, EBITDA gain, and team capacity from profit-first automation — then validate with a free audit on your data.
How this ROI estimate works
The calculator is a scenario model. You set marketplace scale and cost structure; we apply conservative, published-benchmark ranges for ads, promo, pricing, and availability levers, then trim for overlap. Use it to size opportunity — not as a contractual ROI guarantee.
Inputs you control
Annual marketplace sales, EBITDA margin, ad spend share, promo mix, discount depth, and team size.
Levers in the model
Ads, promo, pricing, and availability — with an explicit overlap haircut so levers are not double-counted.
Conservative vs high end
Toggle estimate mode to see a cautious band versus an upside band. Both remain illustrative.

- Is this marketplace ROI calculator a guarantee?
- No. It is an illustrative, scenario-based estimate. Results vary by category, marketplace, and starting point. Marktspan does not promise a specific ROI.
- What does ROI mean on this page?
- Here ROI means the directional relationship between automation-driven sales/EBITDA gains (and team time freed) and the effort of running marketplaces more profitably — not a formal accounting return calculation.
- Where do the benchmark assumptions come from?
- The model uses conservative ends of published ranges referenced in the calculator method line (industry and marketplace-ad research). Overlap between levers is trimmed so totals stay cautious.
- Can I use this for a board or budget case?
- Use it as a conversation starter. For decisions, validate with your P&L and a Marktspan audit on live channel data.
- How is this different from the homepage?
- The homepage embeds the same calculator. This page adds the method explanation, how-to steps, and FAQ for SEO and shareable sales follow-up.
