What the dates and status mean
Recorded last verification means the maintenance record compared the default assumption with the listed official source on that date. It does not mean provider approval, a legal audit, continuous monitoring, or complete coverage of every account rule.
Defaults create an editable starting scenario. If a provider dashboard, contract, or settlement report shows a different rate, replace the default with that first-party account information.
Update policy
An official fee announcement, change to an official help page, credible correction signal, or scheduled content maintenance can trigger a review. Reviews prioritize market, category, plan, payment method, and effective-date conditions. When no universal rate exists, the input remains editable and the limitation is disclosed.
There is no automated scraper, real-time API, or change alert, so official rules can change after the dates on this page. Before a fee adjustment is published, the default input, formula note, example, source link, and related unit tests should be checked together.
Correction-channel limitation
There is currently no public email address, public issue tracker, or on-site submission form. The contact page only documents feedback scope and safety requirements, so a visitor cannot yet rely on it to submit a correction directly. This limitation remains public until a usable and verifiable channel exists.
Do not send passwords, one-time codes, payment data, government IDs, tax records, marketplace credentials, or API keys.
Current calculator records
Summaries describe the default planning values or treatment loaded by each page. Edit every rate to match first-party account records before making a business decision.
TikTok Shop US
Recorded last verification:
The default platform commission is 6%; payment rate and fixed payment fee default to zero. Creator commission, ads, logistics, samples, and expected returns remain separate inputs.
Six percent is not universal across categories or programs. Category exceptions, fulfillment programs, refund administration fees, and seller-specific adjustments require Seller Center and statement verification.
Amazon FBA
Recorded last verification:
The default referral fee is 15% with a $0.30 minimum. FBA fulfillment, storage, and inbound placement use editable per-unit amounts.
Fifteen percent is not universal. FBA charges also vary by category, size, weight, marketplace, inventory program, and service.

Etsy
Recorded last verification:
Defaults use a 6.5% transaction fee, 3% + $0.25 payment processing, a $0.20 listing allocation, and 12% Offsite Ads.
Payment processing varies by seller country. Offsite Ads may not apply or may use the 15% tier; taxes, currency conversion, and renewal behavior can also change the result.
Shopify
Recorded last verification:
The default card fee is 2.9% + $0.30 and the third-party transaction fee defaults to zero. Plan and app costs use an editable per-order allocation.
Rates vary by country, plan, Shopify Payments use, card type, gateway, and currency conversion. The default is not a quote.
PayPal and Stripe
Recorded last verification:
The default US online-payment scenario compares PayPal at 3.49% + $0.49 with Stripe at 2.9% + $0.30.
Payment method, country, international cards, conversion, disputes, refunds, product type, and negotiated pricing can differ. Feature differences are outside the fee comparison.
