AfterFees is an independent, third-party site. It is not affiliated with, endorsed by, or operated by Amazon, Etsy, eBay, Shopify, PayPal, Stripe, Poshmark, Mercari, Depop, Vinted, StockX, Grailed, the IRS, the Social Security Administration, or any other platform, brand, or agency a calculator on this site models. All trademarks and company names belong to their respective owners and are used only to identify which platform a figure applies to.
Every figure on this site is an estimate, produced by an independent operator who is not a licensed accountant, tax preparer, financial adviser, or attorney. Nothing here is financial, tax, accounting, legal, or investment advice, and no relationship of professional advice is created by using these tools.
What that means in practice
These calculators model the common case. They apply published fee schedules and tax tables to the inputs you provide, using the assumptions each page states explicitly. They do not know your full financial position, your filing history, your state's edge cases, your platform's account-specific pricing, or the promotional rate you negotiated. Real outcomes differ, sometimes materially.
Fee calculators
Marketplace and payment-processor fees change without much notice, and some sellers have negotiated or grandfathered rates that differ from the public schedule. Each fee page lists the rate schedule version, the date it took effect, and the date it was last checked against the platform's own page. If our figure and your actual settlement statement disagree, the platform is right. Before you price inventory or accept a contract, check the platform's live fee page.
Tax calculators
The tax tools are the ones to be most careful with. They estimate federal self-employment tax, federal income tax, and state income tax for straightforward situations. They do not account for tax credits beyond those named, the alternative minimum tax, capital gains treatment, multi-state apportionment, non-resident filing, state-level additions and subtractions, or anything specific to your prior-year position.
The quarterly payment schedule is a planning aid, not a filing. Making the payments it suggests does not guarantee you avoid an underpayment penalty. Consult a CPA or enrolled agent before you rely on any tax figure from this site — particularly if your income is irregular, you operate in more than one state, or you have equity compensation.
Rate calculators
The hourly rate and day rate tools produce a number that satisfies the assumptions you enter. They cannot tell you what your market will pay. A rate that is mathematically necessary is not automatically a rate a client will agree to, and the gap between those two is a business problem rather than an arithmetic one.
Unverified rates
Where a rate has not yet been confirmed against its primary source, the page says so directly in the sources section. Treat those pages as structurally correct but numerically provisional.
Your responsibility
You are responsible for verifying any figure before acting on it. AfterFees accepts no liability for decisions made on the basis of these estimates. If a number matters — and on this site it usually does — check it against the primary source, which is linked at the bottom of every page.
