About FeeOrbit

FeeOrbit exists because platform fees are confusing on purpose. Sellers lose money to fees charged on shipping, country-specific processing rates and ad programs they didn't know they were in.

Our calculators are free, have no sign-up and run entirely in your browser. Every fee constant lives in a single verified data source, reviewed quarterly — last verified 2026-10.

FeeOrbit is supported by display advertising and a small number of clearly labelled partner links. These never influence our numbers.
