What this actually is

Acorns is a subscription investing app ($3–$12/month) that rounds up your purchases and invests the spare change. The "referral program" is their marketing: invite a friend, both of you get a small bonus deposited into your Acorns account. It is not free money you can withdraw — it lands in your investment account, and you'll keep paying the monthly fee.

The standard offer

Limited-time promo bonuses

Acorns runs short promotional windows (typically a week) where the bonus is larger if you refer multiple friends in that window. For example, a May 2026 promo offered a $400 bonus for 2 referrals or $700 for 3 referrals, with a promo window of 5/11/2026–5/17/2026. Terms vary every promo.

To find the current promo: open the Acorns app and go to the "Invite friends" screen. The active offer (if any) is shown there.

What to actually do

  1. Decide first whether Acorns itself is right for you or your friend (see "who should skip" above).
  2. If yes, get your referral link from the app: Profile icon (top left) → "Invite friends".
