Terms & disclaimer

These are estimates, not advice

Everything on Stackyfull is a calculation tool for planning purposes. It is not tax advice, legal advice, or accounting advice, and using it does not create a professional relationship of any kind. Payroll and tax outcomes depend on facts these calculators do not ask about — entity type, jurisdiction, elections, prior-year positions, and exceptions that apply to particular businesses.

Before filing anything or making a decision with money attached, check the result with a qualified accountant, payroll provider, or the relevant agency. Every calculator lists the primary sources its figures come from so you can verify them directly.

Accuracy, and its limits

We verify each calculator’s underlying rates against primary sources and show the date that was last done, along with the sources used. That is a real commitment and more than most comparable sites offer. It is not a guarantee of correctness.

Rates change, sometimes mid-year and sometimes retroactively. Our review cadence means a figure can be correct on the date shown and out of date the following week. The date on each page is the claim. If it looks old, treat the result as provisional.

No warranty

This site is provided “as is” and “as available”, without warranties of any kind, express or implied, including any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. MetricMind does not warrant that the site will be uninterrupted, error-free, or that any figure is accurate, complete or current.

Limitation of liability

To the fullest extent permitted by law, MetricMind is not liable for any loss or damage arising from use of this site or reliance on any figure it produces — including underpaid or overpaid tax, penalties, interest, payroll errors, lost profits, or any indirect or consequential loss.

Some jurisdictions do not allow the exclusion of certain warranties or limitation of certain liabilities, so parts of the above may not apply to you.

Acceptable use

You may use these calculators freely, including for commercial work, and you may link to them. Please do not scrape the site at volume, attempt to disrupt it, or republish the calculators as your own.

Changes

These terms may change as the site does. Continued use after a change means you accept the revised terms. Questions go to hello@metricmind.io.
