Disclaimer

Informational content + opinions only. Not tax/legal advice. Here's the longer version.

Education and planning only

The calculators and workbooks on this site are provided for educational and planning purposes. Their results depend on the information and assumptions you enter, and may not reflect:

  • the methods or terms your lender, payroll provider, or plan administrator actually uses;
  • the tax rules that apply to your specific facts, including state and local rules;
  • the terms of a particular contract, policy, or agreement; or
  • the accounting treatment a professional would apply to your circumstances.

Not advice

Nothing on this site is financial, investment, legal, tax, or accounting advice, and no professional relationship is created by using it. Review important decisions — loan terms, tax positions, payroll practices, accounting treatment — with a qualified professional, such as a CPA, an enrolled agent, an attorney, or a licensed financial advisor.

Accuracy and changes

I make reasonable efforts to keep the formulas correct and current, and describe how they are tested on the methodology page. Laws, tax limits, and accounting standards change, however, and a calculator may not reflect the most recent rules. Tax calculators state the tax years they support; confirm current rules before relying on a result. Corrections are listed in the changelog.

Workbooks and journal entries

Downloaded workbooks are generated in your browser from the inputs you chose. Journal entries and schedules are suggestions for your records, not final accounting guidance. Once you change a workbook, its results are your own.

Limitation of liability

To the fullest extent permitted by law, the site and its author disclaim all liability for any loss, damage, cost, or expense arising from the use of, or reliance on, the site, its calculators, or the workbooks they produce. See the terms of use.
