Freeze Dryer Cost Calculator
What does a batch really cost? Pick your machine and what you’ll freeze dry. We add up electricity, food and packaging, compare the cost per serving with buying the same food already freeze-dried, and work out the month the machine pays for itself.

Pays for itself in 10 months
In about 10 months, after 19 batches of home-cooked meals at 2 batches a month.
This assumes you would otherwise buy about $402 a month of store-bought freeze-dried meals — 66 servings. Buy less than that and the payback stretches out; if you would simply eat the food fresh, there is no saving to count.

How the numbers work
Electricity is hours × power × your rate. A batch starts by freezing the food: about 8 hours for an average load of fresh food on the 5- and 7-Shelf, 10 on the Large and 12 on the Mega — less for a lighter load — or 0–4 hours if it goes in already frozen from your own freezer. Main drying then runs as long as it takes to pull the water out — roughly half a pound of water an hour on the 5- and 7-Shelf and twice that on the Large and Mega, matched to our published drying times. The final dry adds 5, 9 or 12 hours depending on how full the trays are (the factory default is 7), and longer for sugary fruit (10 hours) or ice cream (12). Power comes from our own figures for each machine. While it freezes, only the compressor runs: about 400 W on the 5- and 7-Shelf, 550 W on the Large and 600 W on the Mega. Once drying starts the vacuum pump runs too, and the shelf heaters cycle on about a third of the time to hold temperature — an average of about 850 W on the 5- and 7-Shelf with the Premier pump, 950 W with the Commercial pump, 1,200 W on the Large and 1,400 W on the Mega. Our electricity breakdown walks through a measured batch. State rates are the U.S. Energy Information Administration’s 2025 residential averages, adjusted to its 2026 forecast.
Outside the US the rates are official household prices with taxes included, converted to US dollars at the European Central Bank’s rates of 27 October 2026: Eurostat for Europe (first half of 2026), Ofgem’s price cap for the UK (October–December 2026), ElCom’s 2026 median for Switzerland, Hydro-Québec’s comparison of major cities for Canada (April 2025, with the Canada average weighted by population), TEPCO’s standard household for Japan, KEPCO’s 2026 residential average with VAT and levy for South Korea, MBIE for New Zealand and SP Group for Singapore. Anywhere else, enter your own rate.
Food prices are US city averages from the Bureau of Labor Statistics for September 2026, except home-cooked meals and candy, which are our estimates. If you buy in bulk, on sale or grow your own, change the number — it moves the answer more than anything else.
What comes out is worked out from each food’s water content in USDA FoodData Central, leaving about 3% moisture in the finished food. Servings follow the serving size on store-bought freeze-dried labels where there is one — a cup of prepared meal, for example — and a typical portion otherwise, such as one egg or an ounce of cheese.
Store-bought prices are the median of the listings we checked in October 2026 at Walmart, Target, REI, Mountain House, Augason Farms, Nutrient Survival, H-E-B and Lehman’s: $3.50 an ounce for fruit, $2.10 for vegetables, $2.90 for meals, about $4 for meat, $2 for egg powder, $4.55 for ice cream treats and $2.20 for candy. Shop around and you’ll find both cheaper and dearer — change the price under “Store-bought price and other assumptions” to match what you’d buy.
Packaging and upkeep covers mylar bags and oxygen absorbers for the batch, plus a share of pump oil and filters: about $4.63 a batch with the Premier pump, which needs fresh oil every 5 batches, and less with the Commercial pump at every 30.
Shopping from outside the US? The calculator switches to kilograms and US dollars and fills in your country’s electricity price where we have one. Food and store-bought prices stay US averages, so change them to what you pay. And add shipping, which is quoted separately outside the contiguous US, plus any import duty or tax, to the machine price.
What it leaves out: your time, sales tax, cooking food before you dry it, and resale value. The payback date also assumes that everything you make replaces food you would otherwise buy already freeze-dried — the result shows how much that is a month. If you would simply eat it fresh, the savings aren’t real, and the case for a freeze dryer is about shelf life, storage and convenience. Is a freeze dryer worth it? values each kind of food against what you would really do instead.
Questions people ask
How much does it cost to run a freeze dryer?
At the US average of 18.2¢ per kWh, a 15 lb batch in a 5-Shelf with the Premier pump uses about 39 kWh over 50 hours — roughly $7.03 of electricity, plus about $4.63 for bags, oxygen absorbers and pump upkeep. That is for fresh food, which the machine spends the first 8 hours freezing; food you freeze ahead in your own freezer cuts about 6 hours and $0.44 from the batch. A lighter 8 lb batch of fresh food takes about 30 hours, $4.22 of electricity and about $3.32 of packaging and upkeep. Our electricity breakdown measured about 18.5 kWh over 24 hours for an 8 lb batch on the 7-hour default final dry. We count 5 hours of freezing for that much fresh food, the 9-hour final dry we recommend for a medium load and an average drying draw of 850 W, so the estimate here runs about 25% higher. In California and much of New England electricity costs 60–80% more than the national average, so scale the power figure up to match.
Is it cheaper to freeze dry your own food?
For most foods, by a wide margin. At typical prices a homemade serving of a home-cooked meal costs $1.58 against $6.09 for a store-bought freeze-dried meal, and cooked chicken, cheese, ice cream and candy show similar gaps. Fruit bought at full grocery prices is the exception: strawberries at $3.79 a pound cost nearly as much to freeze dry as to buy freeze-dried. The saving there comes from fruit that’s in season, on sale or from your garden.
How long does a freeze dryer take to pay for itself?
It depends on what you dry and how much store-bought freeze-dried food it really replaces. At two batches a month, a 5-Shelf with the Premier pump pays for itself in about 10 months on home-cooked meals — if you would otherwise buy about $402 a month of freeze-dried meals. On candy it takes about 10 months, and on strawberries bought at full price, more than 10 years. If you would eat less store-bought than that, the payback stretches out in proportion.
