About CalcYard

CalcYard is an independent website offering 361 free calculators across real estate investing, personal finance, business, taxes, mortgages, construction, HVAC, health, math, and everyday life.

It exists because most calculator sites bury a simple answer under pop-ups, forced sign-ups, and pages that phone your inputs home. CalcYard takes the opposite approach: every calculator runs entirely in your browser. The numbers you type are never uploaded, stored, or seen by us — the page even keeps working with your internet turned off.

How the calculators are built

Every tool implements the standard published formula for its calculation — see Formulas & sources for the specific references. Each calculator is verified against its formula with automated tests before any update goes live.

Results are estimates for planning and education. They are not financial, tax, legal, medical, or engineering advice — for decisions that matter, verify with a licensed professional.
