Methodology

How we calculate Buy Box ROI

Buy Box revenue

Monthly sales multiplied by your Buy Box win rate equals the revenue you actually capture. Only Buy Box winners get the sale on shared listings.

Profit from captured sales

Captured revenue multiplied by your average profit margin. Your margin should account for product cost, Amazon fees, shipping, and returns.

Repricing improvement

We apply a conservative +20 percentage point win rate improvement, capped at 95%. Industry data shows sellers using automated repricing typically gain 15-25 percentage points in Buy Box share.

Net ROI

Additional annual profit from the improved win rate, minus your Repricing.app subscription cost. Your plan is matched to your sales volume using our published pricing tiers.

This calculator provides estimates based on the inputs you provide. Actual results depend on your product catalog, competition, pricing strategy, and market conditions. The +20pp Buy Box improvement is a conservative estimate based on industry data for sellers using automated repricing tools.
