# 400,000% APY ?

Annual Percentage Yield is referred to as APY. \
\
By accounting for the impact of compound interest, this calculation determines the real rate of return on your initial investment. \
\
The principal in CreFi is represented by your $CREFI tokens, and compound interest is periodically paid on each Rebase event (every 15 minutes), also known as a "Epoch." \
\
Your current CreFi token amount plus your new rebase token amount make up your new main amount. For your subsequent rebase awards, the calculation is based on this total sum. \
\
Compound Interest Works and It's crucial to keep in mind that your balance will increase over time exponentially rather than linearly. \
\
Using a 15-minute compound interest rate of 0.02355 percent:  If you had a balance of just 1 $CREFI on day one, it would have increased to 4000 $CREFI after a year.
