Stack the fees first.
A $50 listing is not $50 in your pocket. eBay takes a final value cut plus a per-order fee. FBA stacks referral and fulfillment. Etsy peels listing, transaction, and processing — sometimes Offsite Ads too. Put the sale in below and see what is left before you buy inventory or hit Publish.

Why people use us
Stack, not a mystery net
Fees show as a stack of lines, not one mysterious “net.”
Three platforms, one desk
Same site for eBay, FBA, and Etsy — compare before you commit inventory.
Dated rates you can override
Rates carry an “as of” date; override the percent when Seller Hub disagrees.
Fees before the listing goes live
A sale price that “feels fine” often dies after the platform cut. On eBay you are usually stacking a percentage final value fee plus a small per-order fee on the total (item + shipping the buyer paid). On Amazon FBA you are stacking referral and a size-tier fulfillment charge before storage and inbound surprises. On Etsy you are stacking a listing fee, a transaction percent, and payment processing — and Offsite Ads can take another bite if that sale was attributed.
Most single-platform calculators hide one of those lines or bury the date the rates were last checked. FeeStackBase keeps the stack visible, runs in your browser, and does not ask for an account. It is an estimate for planning — your Seller Hub or Seller Central payout is still the source of truth.
