Homestead Budget Calculator

The calculator uses one blended average across every species you might raise — chickens, goats, pigs, and everything else — because it doesn't ask which animals you have, just how many. That means the estimate will understate savings for a productive flock of egg-laying hens (worth roughly $83/year each in the underlying assumption) and overstate them for a single dairy goat (worth closer to $800/year), so the more specialized your herd, the less reliable this one number becomes.

Enter it as a yearly total. Unlike the energy and feed inputs, which the calculator explicitly multiplies by 12 to annualize, maintenance is treated as already representing the full year — fencing, equipment repair, and infrastructure upkeep summed over 12 months. Entering a monthly figure by mistake will make Annual Operating Cost look far lower than reality.

-1 means the homestead isn't generating any net savings at all — your annual operating cost exceeds your estimated grocery savings, so there's no positive savings stream to ever pay back the estimated infrastructure investment. It's not an error; it's the calculator's way of flagging that break-even, as defined here, doesn't apply to your current inputs.

It divides your total Annual Operating Cost by a fixed 2,190 meals per year — three meals a day for two people, 365 days a year. If your household is larger or smaller, the reported cost per meal will be proportionally off: a 4-person household actually eating twice as many meals would see roughly half the true cost per meal that this figure shows.

Garden Cost (used on the expense side) is a flat $0.10 per square foot per year, covering seed, soil amendments, and water. Garden Savings (used on the produce-value side) is a much higher $2 per square foot, representing the retail grocery value of what that space actually grows. The two use different rates because one measures your out-of-pocket input cost and the other measures the market value of the output — they aren't meant to be the same number.
