Last verified 2026-05-17. Acorns is a paid investing app — read this before you sign up.
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.
Who this is actually useful for
- You already have an Acorns subscription you're keeping anyway, and want to nudge a friend.
- You can afford the $3+/month fee out of regular cash flow without it eating returns on small balances.
Who should skip it
- You're on a tight budget. A $3/month fee on a $100 balance is a 36% annual drag — far worse than any referral bonus. Free brokerages (Fidelity, Schwab, Vanguard) charge $0 and have no minimum.
- You're being asked to sign up just to get someone else a $5 bonus. The subscription cost will outrun that bonus in two months.
The standard offer
- Invite a friend with your unique referral link (Acorns app → Profile icon → "Invite friends").
- Friend signs up for a new Acorns subscription using your link.
- Friend makes a first investment of $5 or more within 14 days.
- You and the friend each get a $5 bonus deposited into your Acorns Invest account, usually within 30 days. [Source: acorns.com/learn/acorns/acorns-referrals/ (accessed 2026-05-17)]
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
- Decide first whether Acorns itself is right for you or your friend (see "who should skip" above).
- If yes, get your referral link from the app: Profile icon (top left) → "Invite friends".
