Short answer: At Level 1, ether.fi Cash pays one-off bonuses of 10 and 15 dollars plus recurring shares: 0.1% of referred spending, 20% on a physical card, 50% on card issuance and 5% of liquid and staked yield. The recurring part is small per user, so volume of active referrals is what matters.
One-off bonuses versus recurring shares
The referral dashboard splits rewards into two kinds. One-off bonuses pay a fixed amount for a milestone: 10 dollars for a new member and 15 dollars for a high-spend referral. Recurring shares pay a percentage for as long as the referred user keeps spending or earning.
The bonuses are capped: the dashboard shows up to 10 new-user bonuses, and each high-spend bonus unlocks 3 more.
What the recurring share is really worth
A 0.1% share of spending sounds tiny because it is. If a referred user spends 1,000 dollars in a month, that share is 1 dollar. The larger numbers, such as 20% on a physical card and 50% on card issuance, are commissions on card fees, so they depend on how many referrals actually get a card.
The yield shares, 5% on liquid and 5% on staked yield, depend on how much the referred user keeps in those products, not on how much they spend.
Conditions to read before you promote it
Referral rewards are tied to the referred person using the product, and the card involves identity verification and is not available in every country. Levels and rates can change, and rewards may take time to settle, so read the dashboard terms before you plan around any number.
Treat the program as a modest add-on for an audience that already wants a crypto card, not as a primary income source.
