# Stake Formulas and Math

Don't worry, you don't need to know or understand any of this math if you are a regular ape! Just know that everything is algorithmically programmed and built to last! 

You can easily see what you will earn by using the [calculator on the website](https://maxx.finance/#calc)!

### Example

With the above formulas, we can calculate exactly how many shares a user will receive at staking, and how much interest they will earn over the period.

**A user stakes 10,000,000 MAXX for 3333 days, whilst the SF is 1.000:**

**​Basic Shares** = amount / (2-SF)\
`10,000,000 / (2-1) =`` `**`10,000,000`**

**BPB Bonus** = (stake\_amount / 2,000,000) capped at 10%\
`10,000,000 / (2,000,000) =`` `**`5%`**

​**BPB Shares** = BasicShares \* (bpb\_bonus / 100);\
`10,000,000 * (5/100) =`` `**`500,000`**

**LPB Shares** = (BasicShares + BPB Shares) \* (Duration - 1) / MN\
`(10,000,000 + 500,000) * (3333 - 1) / 1111 =`` `**`31,490,549.0549`**

&#x20;**Total Shares** = Basic Shares + BPB Shares + LPB Shares\
`​10,000,000 + 500,000 + 31,490,549.0549 =`` `**`41,990,549.0549`**

**Full Duration Interest** \
(stake\_total\_shares \* (stake\_duration/365)) \* base\_inflation\
`​(41,990,549.0549 * (3333/365)) *` 0.18185 `=`**`69,728,015.9589 MAXX`**

**Annual Interest** \
((stake\_total\_shares \* (stake\_duration/365)) \* base\_inflation) / stake\_duration\*365\
`((41,990,549.0549 * (3333/365)) * 0.18185) / 3333 * 365 =`**`7,635,981.3456 MAXX`**

**Annual Interest APY%**\
Annual Interest / Principal Amount\
`7,635,981.3456 / 10,000,000 = 0.76359813456 /`**`76.36% APR`**

\
**With this, we can see that the user will earn a fixed 76.36% APR for his 3333 Day Stake of 10m MAXX.  He will earn a total of 69,728,016 MAXX, making the total withdrawable amount 79,728,016  MAXX**
