Fee announcements follow a genre: three paragraphs about investing in your success, one sentence of numbers, and a link to updated terms nobody clicks. Skip the genre; extract three facts.
The rate change is the headline everyone reads. The base change is where the money usually moves. History's biggest seller-fee increase in the UK wasn't a percentage going up — it was Etsy's 2018 change quietly extending the fee to postage as well as the item, which cost a postage-heavy seller more than the simultaneous 3.5%→5% rise did. Whenever you see "we're simplifying our fees", read for the base: item only, or item plus delivery? Gross or net of discounts? Per order or per item? A flat rate on a wider base beats a raised rate on a narrow one for the platform, and announcements know which one photographs better.
Effective dates decide your admin: fees that apply to new listings (Depop's 2024 change) mean relisting work captures the benefit; fees applying to all sales from date X (Etsy's rises) mean your repricing has a deadline. Grandfather clauses hide in both directions — Depop's old 10% contract still clings to pre-2024 listings that were never relisted, which is free money lost to inertia.
Take yesterday's most typical order and run it under the new structure, by hand or with a calculator that's already updated. Percentages mislead at a glance ("0.48% is tiny") while orders tell the truth ("that's £19 a month at my volume"). Only the order-level number can answer the real questions: absorb, reprice, or — the option always worth pricing — shift weight toward a channel that didn't just get dearer.
