Free Sample ROI Calculator
Sending free products to creators? Work out the true cost, expected sales and ROI before you ship a single sample.
How it works
ROI = (Expected profit − Campaign cost) ÷ Campaign cost.
Sample seeding is a numbers game: if 40% of 20 creators post and each video drives 15 sales at $6 profit, that's $720 gross on a $160 investment. Track your real post rate and sales-per-video after each campaign and update the inputs — your numbers beat any default.
Frequently asked questions
How many samples should I send?
Start with 10-20 to creators in your niche, measure the post rate and sales per video, then scale what works.
What is a good post rate?
30-50% is typical for well-targeted outreach. Below 20%, your targeting or offer needs work.
Should sample cost include shipping?
Yes — the full landed cost of getting the sample into the creator's hands is the true investment.
