# Supply Inflation

The total circulating supply of WISE inflates at a constant rate of 4% per year. At the end of every day of the Circulation Epoch, the contract calculates how many new WISE will need to be minted for that day in order to achieve that rate of inflation.

``````totalWiseSupply = circulatingWise + stakedWise
dailyInflationRate = (1.04 ^ (1 / 365) - 1)
dailyInflationRate =~ 0.0001074597820279

newWiseToday = totalWiseSupply × dailyInflationRate``````

These new daily inflation WISE are not immediately minted. Instead, they are earmarked for distribution to two parties: three quarters (3% inflation) to all active stake shares on that day, and one quarter (1% inflation) to all active, qualified CM shares that day. Each active stake is earmarked a fraction of this new WISE in proportion to the stake's shares' percentage of the total share pool that day. The same apportionment scheme is used for the WISE earmarked to qualified CM shares.

An example scenario:

``````On day X, suppose there are:
100,000,000 total circulating WISE
30,000,000 total staked WISE
10,000,000 total shares

The total new WISE that will be generated this day is then:
newWiseDayX = (100,000,000 + 30,000,000) × 0.0001074597820279
newWiseDayX = 13,969.771663627 WISE

This new WISE is split into two amounts:
three quarters for stake shares (i.e. 3% inflation)
one quarter for CM shares (i.e. 1% inflation)

Now, suppose user A has an active stake that is 2,000,000 shares.
On day X, this user's stake then gets some WISE earmarked for it:
userANewWiseDayX = newWiseDayX × (3/4) × stakeShares / totalShares
userANewWiseDayX = 13,969.771663627 × (3/4) × 2,000,000 / 10,000,000
userANewWiseDayX = 2,095.46574954405 WISE``````
