- 💰 Revenue: Marginal — $320 - $2005/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 5.0★ across 1 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: Insufficient signal to assess trajectory.
- ⚠️ Risk: Low — no material risk signals detected.
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $14K-$25K. Portfolio play ($14K/mo combined) commands premium.

📝 About this app
Most margin calculators stop at sale price minus cost.
Seller Profit Calculator goes further. It helps online sellers calculate real profit after the costs that actually affect every sale: marketplace fees, delivery charges, sales tax, product cost and margin.
Use it before you list, re-list, accept an offer, or reprice an item so you know what you are likely to keep.
Designed for independent sellers, resellers, makers and small product businesses, our app helps you model selling prices quickly without having to remember formulas or rebuild the same calculation every time.

About this analysis
Why low confidence: only 1 rating · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Gross Margin Calc is a very early-stage iOS app in the business space with weak public traction — only 1 rating, no founder-verified MRR, and not ranked in any monitored grossing chart. The app appears to be monetised, but public signals are too sparse for a precise revenue estimate.
Bottom line: treat all revenue, audience and acquisition-value numbers on this page as directional only — not founder-verified facts.
