About Royales Finance

Royales Finance is a quiet corner of the internet for people who want a clear estimate and a straight explanation. We focus on practical calculators and readable guides—not market headlines, stock tips, or ranked product lists.

How the calculators work

Mortgage, loan, investment, retirement, and credit card math runs in your browser. Your inputs are not sent to a server to produce a result, and you do not need an account. Formulas live in documented TypeScript functions so they can be reviewed and improved over time.

How we write

Each guide aims to define a concept, walk through a worked example with round numbers, and point to a related calculator when it helps. We do not invent reviews, “guaranteed” returns, or personalized recommendations. When a result depends on an assumption, the page says so.

How we show money

Amounts appear in U.S. dollars. Mortgage examples can include property tax, homeowners insurance, and HOA dues so the monthly picture is closer to real life than principal and interest alone.

Questions about the site itself belong on the contact page. Please read the financial disclaimer before relying on any estimate.
