APY

The app shows an APY (annual percentage yield) next to each vault, usually a 30-day figure and an all-time figure. APY is the annualized, net-of-fees return of one vault share, built from its price per share (PPS) over time.

How it's calculated​

T3tris uses a TVL-weighted method: a large move on a small amount of capital doesn't dominate the figure, a move on a large amount of capital counts for more. This avoids a misleading headline where a +30% move on 1 USDC would look as significant as a +10% move on 100,000 USDC.

  • APY 30d: annualized from roughly the last 30 days, refreshes frequently.
  • APY all-time: annualized over the vault's entire history since launch.

Gross vs net​

The headline APY is the net return, what you keep after fees. Some views also show a gross figure (before fees) and the fee drag (the difference), useful for comparing vaults with different fee schedules.

Projected yield​

On a vault page you may see a projected yield for a chosen period (day, week, month, year). It applies the vault's recent APY to your amount and time horizon. It's an illustration for intuition, not a forecast or a guarantee.

Reading it responsibly​

APY is backward-looking, not a promise. A short history means a noisy APY, a brand-new vault has little data to annualize. Annualizing amplifies: a strong or weak short window, scaled to a year, can look dramatic. Always check the performance chart, not just the headline. And APY is net of fees, not of risk, it says nothing about how much risk was taken to earn it. See Vault Ratings.
