Not every “canner” can actually can.
We rank 15 home pressure canners by cost per quart of capacity, from $5.82 to $33.33 a quart — price ÷ quarts — scoped to the stovetop equipment class USDA processes were written for. Electric multi-cookers with canning buttons are excluded and explained: NCHFP is on record. We publish no process times and no safety advice — we index the record and the math.
What we measure
Four facts per canner — the price math, and the three columns that stop the cheapest number from being the whole story.
Price ÷ quarts of capacity. The only fair way to compare a $128 22-quart against a $350 10.5-quart.
Whether it’s the stovetop equipment class USDA processes were developed on — per NCHFP’s guidance. Electric multi-cookers are not.
Dial gauges need an annual accuracy check (your extension office does it); weighted gauges don’t — but give no readout. Some canners carry both.
From Presto’s 12-year to All American’s lifetime — buy-once economics change the per-quart math over decades.

$ / quart = current price ÷ quarts of liquid capacity (jar counts per load are on each canner’s page — a 16-quart and a 23-quart both hold 7 quart jars; the bigger pot fits more pints). USDA class means a stovetop pressure canner in the equipment class NCHFP’s guidance describes — the USDA and NCHFP publish guidance, not equipment approvals, and neither certifies canners. Dial gauges need annual accuracy checks; weighted gauges don’t. We publish no process times and no safety advice — for tested recipes use NCHFP, the USDA Complete Guide, or your extension office. Prices drift; the linked listing is authoritative, and each row records its price date in the dataset. Some product links are affiliate links — if you buy through them we may earn a commission, at no cost to you. As an Amazon Associate we earn from qualifying purchases. Links appear only on canners in the USDA equipment class — never on the excluded rows — and they never change the ranking.
Sold for canning — but the authorities never validated them
Electric multi-cookers and digital canners are marketed with canning buttons and even “meets USDA guidelines” claims. NCHFP is on record that USDA pressure processes were not developed for electric multi-cooker appliances, and no authority has validated one. They are kept out of the ranking entirely — each card links the full sourced answer.
Why this ranking is different
The canning button isn’t a process
USDA process times assume a stovetop canner’s heat-up, venting and cool-down. NCHFP’s statement on electric multi-cookers is public and quotable — we quote it. The Instant Pot answer →
“Meets USDA guidelines” ≠ USDA-recommended
One electric canner claims it — on the maker’s own thermocouple testing. Real engineering, still a manufacturer claim; extensions still say stovetop. The label, decoded →
The lids are the other trap
Counterfeit “Ball” lids on Amazon fail to seal — documented since 2020 and acknowledged by Ball’s parent. A jar that doesn’t seal is spoilage waiting. How to spot them →
