Will a freeze dryer pay for itself in your house?
Short answer: It depends on your numbers: savings per batch times batches per month have to cover the machine price. This calculator counts electricity, food and supplies, leaves out repairs, pump replacement and your time, and many owners may never break even on savings alone.
An honest calculator using your own numbers, not a sales pitch. Many "worth it" answers skip the electricity and bags. This one counts them, but it leaves out repairs, pump replacement and your time.

Your numbers
Example values; replace with yoursExample: about $0.18, near the US residential average (EIA Electric Power Monthly, Table 5.6.A (opens in a new tab)). Check your bill.
Example: 25 kWh. Estimate roughly 13 to 60 kWh per batch, based on Harvest Right's own figures, depending on size and cycle length (Harvest Right (opens in a new tab) lists ~1.0 to 1.2 kW average draw for Small/Medium, 1.5 kW Large, 1.7 kW X-Large, and 13 to 35 hr batches). Other makers don't publish kWh per batch; Blue Alpine lists 1,080 to 1,440 W average draw. Measure yours with a plug-in meter.
