CalcFi

The product is a suite of free financial calculators that cross-check mortgage, paycheck, debt, and retirement figures against each other to show how one decision affects the others, with every formula cited to primary sources such as the IRS, Federal Reserve, Treasury, and BLS. It serves individual consumers, including home buyers, tax filers, debt payers, and small business owners, as well as business users needing personal finance decision support. It is delivered as a browser-based SaaS with no signup or paywall, calculations run locally and refreshed against live federal data.
