How to Use the Free Sample Marketing ROI Calculator
Handing out free samples lowers the barrier to purchase by letting people try before they buy, but production and distribution costs can add up fast - and it's hard to know whether a campaign actually paid off without running the numbers. This calculator takes your sample unit production cost, quantity distributed, fixed distribution cost (shipping, labor), the conversion rate from sample to purchase, and average order value, and returns total campaign cost, expected revenue, and ROI.
The logic: total cost (unit cost × quantity + distribution cost) is compared against expected revenue (quantity × conversion rate × average order value). An ROI above 0% means the campaign at least broke even; above 100% means you earned back more than double what you spent.
Conversion rates tend to run much higher when you target an interested audience instead of distributing randomly, and when you include a discount code or QR code with the sample to directly drive a purchase. Try running a few different conversion rate scenarios to help plan your campaign.
