Free Homesteading & Land Calculators
Every calculator below is free to use, runs in your browser, and needs no sign-up. Each one is built around a decision US homesteaders and rural land buyers actually face: what a parcel will cost to finance, how big a lot really is, how much soil to buy, or how much water and power a homestead can produce.

Use the numbers with the guides
Calculators give estimates, not quotes. Before you commit money, check the figures against our guides — for example what to check before you buy homestead land, rainwater collection laws by state and off-grid solar power systems — and with your lender, county office or installer.
