Example estimate
🔋 Power bank 10–20k mAh
Buy (US): $28.00 · Weight: 0.4 kg · qty 5 · Category surcharge: ×1.2
Lithium rules raise shipping cost; some corridors ban or delay these items.
How we calculate
- Ship USD = max(forwarder min, weight × $/kg) × category surcharge.
- Landed local = buy + shipping + duty estimate + marketplace logistics.
- Sell price is set so that after marketplace fee you hit the target margin (~30% in the example).

Pre-buy checklist
- Re-run with your real weight and buy price — presets do not replace your invoice.
- Check comparable listings on the marketplace, not only your target margin.
- Factor returns, certifications, and lithium/liquid restrictions.
- USD FX moves — leave a buffer on exchange rate.
