BJ's Wholesale Propane Refill: $13-$15 for a 20lb Tank in 2026
How Much Does a BJ's Propane Refill Cost?
A 20lb propane tank refill at BJ's Wholesale costs about $13-$15 in 2026 (roughly $2.82-$3.12 per gallon), and a 30lb tank runs about $20-$22. BJ's fills your own tank by the gallon at the club's propane station, so you pay only for the propane that goes in - not a flat exchange fee. A BJ's Club Card membership ($60/year) is required, and clubs fill 20lb and 30lb tanks only.
Per-gallon ranges are pegged to the latest EIA residential propane average (EIA week ending 2026-03-30: $2.674/gal) plus a typical warehouse-club markup, so they refresh as the EIA SHOPP weekly series updates.
