# How APRs are Calculated

### What is APR and APY? <a href="#what-is-apr-and-apy" id="what-is-apr-and-apy"></a>

APR stands for Annual Percentage Rate and is as the name suggests the rate of return you would receive over the year for staking in a given pool if the value of your capital, as well as the value of the reward coin, don't change in this time. At GoldMint Finance we also quote the daily APR which is the return you receive daily for staking in a pool, this is simply calculated by dividing the APR by 365.APY stands for Annual Percentage Yield and is the compounded return you would receive over the year. Due to compounding APY figures quoted are higher than APRs. In GoldMint Finance all returns are labelled as APR not APY as rewards are not automatically compounded if you compound your returns which we recommend you do you will have a higher yield. You can read more on the differences between APR and APY here:

### How to calculate APRs?

### Vault APRs <a href="#vineyard-aprs" id="vineyard-aprs"></a>

Every day in the Vault there are \~81.5 SGLDM released in total across all the pools. The total amount of SGLDM released per day cannot be changed and is hardcoded in the smart contract. What does, and can change, is the amount of SGLDM out of this \~81.5 that are distributed to each individual pool. This is known as the pool weighting and can be adjusted by the dev team in order to adjust pool APRs. Pool APRs are determined by a number of factors including the current market price of SGLDM, the TVL of that pool and the amount of SGLDM that gets sent to that pool each day (weighting). If the price of SGLDM declines, the APR will drop, and likewise if the price of SGLDM increases, so too will the APR. However, if the TVL in the pool increases, the APR will decrease, and if the TVL in the pool decreases, the APR will increase.

#### **Vault Daily APR Formula:** <a href="#vineyard-daily-apr-formula" id="vineyard-daily-apr-formula"></a>

(Amount of SGLDM rewarded to pool per day x price of SGLDM) / TVL of pool

#### **Current Vault Pool Weightings (SGLDM per day):** <a href="#current-vineyard-pool-weightings-wine-per-day-as-at-11-03-22" id="current-vineyard-pool-weightings-wine-per-day-as-at-11-03-22"></a>

GLDM/PAXG LP - 70%

SGLDM/USDC LP - 20%

GLDM - 5%

BGLDM - 5%

### Mint APRs <a href="#winery-aprs" id="winery-aprs"></a>

APRs in the Mint (Boardroom) are calculated differently from the Vault as the reward token is GLDM instead of SGLDM and the amount released per day will differ depending on the circulating supply of GLDM. The Mint also only mints new GLDM when the TWAP of GLDM is above 1.01. The amount of GLDM that is minted per epoch is calculated by multiplying the current expansion rate by the current circulating supply of GLDM. The expansion rate of GLDM per epoch can be adjusted to slow down or increase expansion. The APR depends on the number of newly minted GLDM last epoch, the price of GLDM on the market and the TVL of the Mint which in turn is determined by the price of SGLDM and the number of SGLDM staked.

#### **Mint Daily APR Formula:** <a href="#winery-daily-apr-formula" id="winery-daily-apr-formula"></a>

((Amount of new GLDM minted last epoch x Price of GLDM) x 4) / TVL of Mint

Keep in mind the above formula is simplified and doesn't take into account the compounding nature of newly minted GLDM each consecutive epoch and therefore is an estimate based on the amount of new GLDM minted last epoch. To find the number of new GLDM minted per epoch you need to find the current circulating supply of GLDM (shown on the homepage of our site) and multiply this by the current epoch expansion rate which, at the time of writing, is 0.5%.​​
