Estimate your freeze-dryer cost per batch
Enter what one batch actually consumes, then choose how many batches you want to use when spreading the machine price.
Calculated costs
Fully loaded cost $51.65 per batch. Operating cost $43.33 per batch. Fully loaded cost $4.13 per fresh pound.
- Electricity / batch
- $2.08
- Operating / batch
- $43.33
- Equipment / batch
- $8.32
- Operating / fresh lb
- $3.47
- Fully loaded / fresh lb
- $4.13
- Monthly operating
- $129.99
- Annual operating
- $1,559.88
Operating cost includes food, electricity, packaging, and the maintenance reserve. Monthly and annual figures use operating cost and your batch cadence; they do not add equipment amortization.
What the freeze dryer cost-per-batch calculator includes
food + electricity + packaging + maintenance + equipment per batchThe calculator keeps operating cost separate from equipment amortization. Operating cost covers the batch itself. Equipment amortization divides the machine price by the number of lifetime batches in your scenario; it does not predict how long a machine will last.

Electricity has a published range
Harvest Right currently estimates about $1.25–$2.80 in electricity per batch for small and medium home units, $2–$3 for large, and roughly $4 for XL. Those are manufacturer estimates, not a promise for your utility rate or cycle. The page was last checked July 18, 2026. For a location-based starting point, use the state electricity-cost calculator.
| Model | Published estimate | Midpoint example |
|---|---|---|
| Small | $1.25–$2.80 | $2.03 |
| Medium | $1.25–$2.80 | $2.03 |
| Large | $2.00–$3.00 | $2.50 |
| XL | About $4.00 | $4.00 |

In the default examples, food moves the result more than power
If a medium batch holds 12.5 pounds and the loaded food averages $3 per fresh pound, the food input is $37.50 before power or packaging. A garden surplus may cost much less; premium meat may cost far more. Use the cost of what you actually load—not a national grocery average that does not match your batch.
When you compare the finished result with a retail product, match quantity and quality as closely as possible. The home-versus-store guideexplains why a mismatched comparison can make savings look larger than they are.
Packaging and maintenance should be visible
Bags, jars, oxygen absorbers, labels, and pump supplies vary by storage method. The manufacturer also calls for pump-oil service at regular batch intervals on applicable pumps. Freeze Dryer Value keeps packaging and the maintenance reserve as separate editable inputs because the purchase pattern differs by household.
- Count only packaging used for the batch being compared.
- Spread bulk purchases across the number of batches they support.
- Add a pump-oil or maintenance reserve if your setup needs one.
- Keep labor separate unless you deliberately value your time.
