Frequently Asked Questions
What counts as net profit in this calculator?
Net profit = sale price − referral fee (category-based, with the $0.30 minimum) − estimated FBA fulfillment fee − COGS − PPC ad spend per unit. It does not subtract the Professional plan's $39.99/month, since that's a fixed cost independent of any single sale — the monthly summary below the per-unit result does account for it.
How accurate is the FBA fulfillment fee shown here?
It's an estimate. Amazon does not publish exact FBA fulfillment fees outside Seller Central — they depend on precise dimensional weight and size-tier boundaries that Amazon only shows after you list a product. The tiers here are a simplified 4-band estimate; check the Revenue Calculator in Seller Central for your exact SKU before setting a real price.
Is the referral fee rate accurate?
Yes — referral fee rates and the $0.30 minimum are verified directly against Amazon's official pricing page, current as of August 2026. Some categories (Jewelry, Watches, Clothing) change rate at a price threshold, which this calculator applies automatically.
Should I include PPC spend if I'm not running ads?
No — set it to $0. Many FBA sellers do run Sponsored Products ads to rank for competitive keywords, so the field defaults to a small placeholder value, but organic-only listings should zero it out for an accurate profit figure.
Individual vs Professional plan — how does that change the math?
Toggle the checkbox below the inputs. Individual costs $0.99 per item with no monthly fee; Professional costs a flat $39.99/month regardless of volume. The per-unit numbers are identical either way — only the monthly summary differs, since Professional's fixed cost gets spread across all your monthly units.
