The Founding Year — Couples is AION's annual couples membership — $2,500 billed once per year (plus applicable tax). That's $208.33/month, locking in two free months compared to paying monthly. Membership rates increase 3% annually upon renewal — $2,500/year increases by $75 to $2,575/year (about $214.58/month) in year two. Charges begin September 1st. This small increase helps us keep up with rising costs and continue investing in coaching, equipment, and the AION experience.
