Terms of use, briefly
- 01
Free to use
Every tool and guide on this site is free, without accounts or signups. You may use the results personally or commercially.
- 02
Estimates, not advice
Everything here is general information built from stated assumptions. It is not tax, legal, investment, or financial advice, and no professional relationship is created by using it. Decisions based on these numbers are yours; for significant ones, consult a qualified professional.
- 03
No warranty
We test the math and date our constants, and still make no warranty of fitness or accuracy. Rates, brackets, and third-party fees change; a page can lag reality. The site is provided as is, and our liability is limited to the amount you paid to use it: zero.
- 04
Content and data
You may quote pages and reuse published datasets with a link back. Wholesale republishing of tools or guides is not allowed. These terms may change; this page always carries the current version.
