# Fee Time Scheduler Math

There are two types of fee time schedulers:

1. **Linear**
2. **Exponential**

# Linear Fee Time Scheduler Formula

A linear fee time scheduler is a fee reduction mechanism that decreases trading fees at a constant rate over time.

For Linear \[0]:

<div style={{ fontSize: "0.9em" }}>
  ```math theme={"system"}
  \text{Ending Fee} = \text{Cliff Fee Numerator} - (\text{Number Of Periods} \times \text{Reduction Factor})
  ```
</div>

Where:

* `cliff_fee_numerator`: The initial fee amount at the start
* `number_of_periods`: The number of time periods
* `reduction_factor`: The constant amount by which the fee decreases each period (expressed in basis points)

# Exponential Fee Time Scheduler Formula

An exponential fee time scheduler is a fee reduction mechanism that decreases trading fees by a percentage of the current rate over time.

For Exponential \[1]:

<div style={{ fontSize: "0.9em" }}>
  ```math theme={"system"}
  \text{Ending Fee} = \text{Cliff Fee Numerator} \times \left(1 - \frac{\text{Reduction Factor}}{10000}\right)^{\text{Number Of Periods}}
  ```
</div>

Where:

* `cliff_fee_numerator`: The initial fee amount at the start
* `reduction_factor`: The reduction factor (expressed in basis points)
* `number_of_periods`: The number of time period
