What you get
Koyfin is a charting, market data and portfolio analysis platform. It has a free plan, and its paid plans currently start at $39 per month for Plus, with Premium at $79 per month and advisor plans above that (monthly prices from Koyfin's pricing page).
When you join through a friend's invite link, Koyfin takes 10% off your first paid subscription. There's no code to type: the discount is attached to your account when you sign up and is held on the pricing page until you upgrade.
Who qualifies
- New Koyfin users only.
- Sign up through the invite link. A free account is enough to lock in the discount.
- Koyfin doesn't publish a minimum spend or a deadline for using the discount.
How to claim it
- Open the Koyfin invite link on this page.
- Click Create account and set up a free Koyfin account.
- When you're ready to upgrade, open the pricing page. The 10% discount is already applied.
- Pick a paid plan and check out.
Good to know
- Koyfin says the discount applies to your first subscription. It doesn't say whether it carries over to renewals, so plan on it covering the first billing period.
- If you get a refund or file a chargeback, Koyfin cancels the referral rewards on both sides.
- Koyfin doesn't say whether the discount combines with other promotions.
Koyfin discount code FAQ
Do I need a credit card to claim the Koyfin discount?
Koyfin only asks for a free account to hold the discount. You pay when you choose a paid plan.
Is there a Koyfin promo code to type in?
No. The referral works through the invite link, so there's nothing to enter at checkout.
Does the 10% apply to every Koyfin plan?
Koyfin says it applies to your first subscription and doesn't limit it to particular plans. Check the price on the pricing page before you pay.
Can I use it on an existing Koyfin account?
No. The referral discount is for new users.
About this link
This is my personal Koyfin invite link. If you subscribe to a paid plan, Koyfin gives me $20 in Koyfin credit about 30 days later. It doesn't cost you anything extra.
