Last updated: September 8, 2026

Informational use only

All tools and content on CalcRoost are provided for general informational and educational purposes. Nothing on this site constitutes financial, investment, tax, accounting, legal, or professional advice, and it should not be relied upon as a substitute for advice from a qualified professional licensed in your jurisdiction.

Results are estimates

Calculator outputs are estimates derived from the inputs you provide and standard formulas. Real-world outcomes depend on factors no calculator can capture in full: platform policy changes, tax law changes, local rules, insurance, and your specific circumstances.

Defaults for fees, rates, and brackets reflect common published figures as of the last-updated date shown on each page, but they change frequently. Always verify critical figures against the official source linked on each page.

No professional relationship

Using this website does not create an advisor-client, accountant-client, or attorney-client relationship.

Accuracy, to the extent we control it

We work hard to keep formulas standard and defaults sourced — every page shows its formula, its sources, and its last-updated date. Still, we make no warranty of accuracy, completeness, or fitness for a particular purpose, and we accept no liability for decisions made based on the site's outputs.

External sources

Pages link to official sources such as Amazon Seller Central, the IRS, HMRC, and state agencies for verification. Those third-party sites are responsible for their own content.

Jurisdiction

Tax tools primarily reflect United States federal rules unless a page states otherwise (UK, UAE, Ireland and other markets have dedicated pages). Your obligations may differ by state, province, or country.
