Freeze Dryer ROI Calculator
A freeze dryer is a $3,000–5,000 bet. Before you place it — or to check the one you already made — see exactly when the machine pays for itself and what it earns over three years.
How the math works
payoff months = (machine + accessories) ÷ monthly profit
3-year net = monthly profit × 36 − (machine + accessories)
Sell-through is the honesty knob most ROI calculators leave out: bags get given away, crushed, sampled, or simply don't sell. Even 90% shifts your payoff date by weeks.
Profit per batch should come from real unit economics — if you haven't yet, run the batch cost and pricing calculators; the pricing tool can send your per-bag profit straight here.
Freeze dryer ROI FAQ
How long does it take a freeze dryer to pay for itself?
Running candy as a real side business — 3 batches a week at ~$100 profit per batch — a $3,800 setup pays off in roughly 3 months. As an occasional hobby, expect a year or more. Batches per week and profit per batch are the only two levers that really matter.
How many batches can one machine run per week?
Candy cycles take 24–36 hours, so 4–6 batches is the physical ceiling. Sustainable one-person schedules are usually 2–4 once you count unloading, bagging, and defrost time.
Is freeze-dried candy still profitable in 2026?
Yes, for sellers who price from real costs: 55–75% margins on $8–14 bags clear $80–150 per batch. The ones who fail almost always priced by copying competitors and never counted electricity, packaging, machine wear, or their own time.
Should I buy new or used?
Used machines run 60–75% of new prices, which can cut months off payoff — but the vacuum pump is the wear item, and a tired pump means failed batches. If you buy used, budget for pump service and test a full cycle before handing over cash.
🛠 Pricing a full setup?
- Harvest Right freeze dryers — current prices for small/medium/large home units.
- Mylar bags in bulk — buying 500+ at once roughly halves your per-bag cost.
- Impulse heat sealer — the one accessory you shouldn't cheap out on.
