# Fixed APY

**APY** is an abbreviation for Annual Percentage Yield. This measures the real rate of return on your principal amount by taking into account the effect of compounding interest. In the case of Clock24, your $C24 tokens represent your principal, and the compound interest is added periodically on every Rebase event (Every 10 minutes), known as an 'Epoch'. &#x20;

Your new principal amount is your then current Clock24 token amount, plus your new rebase token amount. This total of this amount is then considered the principle calculated for your next rebase rewards.&#x20;

Using a Positive Rebase formula, C24 allows token distribution to be paid directly proportional to epoch rebase rewards, worth 0.018 percent of the total amount of $C24 tokens held in your wallet every 10 minute epoch period. The rebase rewards are distributed to all $C24 holders on each EPOCH (10 minute rebase period). There are a total 52,560 EPOCH in a year.

**The Power of Compound Interest** - It is important to note that your balance will grow not linearly but exponentially over time. Taking a compound interest of 0.01855% / 10 minute&#x73;**:**

#### <mark style="color:green;">**EXAMPLE 1**</mark>**:** If you started with a balance of only 1 $C24 on day 1, after a year, your balance will have grown to 12,846.15 $C24.

#### <mark style="color:green;">**EXAMPLE 2**</mark>**:** If you started with a balance of only $1,000 on day 1, after a year, your balance will have grown to $1,284,6157.26.
