About OpenBookMoney

OpenBookMoney is a free personal finance site that explains money in plain English, with step-by-step guides, practical small business ideas and 56 calculators that run right in your browser.

What we do

Money decisions shouldn’t require a finance degree. We turn topics like budgeting, saving, investing, credit, retirement and crypto into clear explanations and practical next steps, so you can make confident choices with your own numbers.

  • Guides that explain how money works, from first steps to advanced strategies.
  • Business idea guides with typical startup costs, launch steps and ways to find your first customers.
  • Free calculators for loans, mortgages, savings, investing, retirement and everyday decisions.

Who writes our content

Our content is created and maintained by OpenBookMoney Editors, the site’s editorial team. We research each topic, explain it in plain language and review every article before it’s published and whenever we update it. Read our editorial policy to see how we work.

What we stand for

  • Plain English. We explain financial terms instead of hiding behind them.
  • Accuracy. We check figures, rules and examples against reliable sources and update pages when things change.
  • Independence. No company pays to be featured or recommended in our content.
  • Privacy. Our calculators run in your browser. You don’t need an account, and we never ask for personal details to use them.

Education, not advice

OpenBookMoney provides general educational information. It isn’t personalized financial, investment, tax or legal advice. For decisions about your own situation, consider speaking with a qualified professional.
