How this is calculated
A deliberately simplified version of the Product Profitability Calculator for someone evaluating their very first product idea — one blended fee percentage instead of itemized marketplace fees, plus an optional one-time cost (samples, tooling) to see how many units you need to sell to break even on it.
Blended fee % is a placeholder for whatever combination of marketplace referral fee, payment processing, and platform costs you expect — refine with the full Marketplace Fee Calculator once you've picked a specific channel.
