About Us

Business Owner Calculators offers free tools and plain-English guides for small business owners, freelancers and contractors in the United States, in English and Spanish. Our goal is to make everyday numbers like margins, break-even, taxes and loan costs easier to understand.

We are an independent informational site, not accountants, lenders or attorneys, and the site is supported by advertising.

Important: these tools and guides are educational estimates, not financial, tax or legal advice. Results depend on your inputs and current rules. Talk to a licensed CPA, attorney or lender before making decisions.
