# APYs

**This page** is about APYs. There's also [estimates of APY vs time](apys-plot.md) and [a guide to estimating APYs](apys-guide.md).

# About APYs

### Source of Rewards

Rewards are earned by users that participate in one or more Data Farming streams. Passive DF allows passive holding of veOCEAN; Active DF streams require more work from the user.

Historically, annual percentage yields (APYs) are 5-15%. See for yourself: in [DF app](https://df.oceandao.org/activerewards) and scroll down to "Data Farming History".

You can do your own APY estimations. In Passive DF, APY is highly dependent on the locked amount *and* duration of lock. In other DF streams, there are other factors.

### Definition of Yield, WPY, APY

A **yield** is the relative gain in value compared to the amount you started with. Specifically:

`yield = (start amount + gained amount) / (start amount) - 1.0`

For example, if you start with 1000 OCEAN and earn 5 OCEAN:

`yield = (1000 + 5) / (1000) - 1.0 = 0.005`

We can express yield as a percentage simply by multiplying by 100 (%). For example, yield of `0.005` in percentage is `0.005 * 100% = 0.5%`.

The yield for one week is **Weekly Percentage Yield**, or **WPY**. For example, if you started with 1000 OCEAN and earned 5 OCEAN from DF, in one week, then your WPY = 0.005 = 0.5%.

The yield for one year is **Annual Percentage Yield**, or **APY**. APY can be estimated from WPYs. Assuming no compounding, `APY = WPY*52`. We drill deeper in the [guide to estimate APYs](apys-guide.md).
