Freezer Vacuum Sealer Calculator

How much extra freezer do vacuum bags get you?

See how much extra freezer capacity you gain by vacuum sealing instead of bagging or boxing. Sealed flat packages save 30–40% of freezer volume and extend storage life 3–5x by preventing freezer burn.

Compression rates are industry-standard estimates from vacuum-sealing manufacturer documentation and USDA freezer-burn / quality-loss research.

01
Compression by content
Meat compresses ~40% (no air pockets in tissue), vegetables ~35%, prepared meals ~30%, mixed contents ~35%.
02
Effective volume gain
Effective capacity = original cu ft × (1 + compression %). A 15 cu ft freezer with sealed meat behaves like ~21 cu ft of loose storage.
03
Quality life multiplier
Removing air prevents oxidation and freezer burn (USDA), extending best-quality storage life by 3–5x for sealed packages.
