The formulas to calculate fixed cost are:

1. Total Variable Cost (\(C_v\)):

\[ C_v = v \cdot D \]

2. Total Cost (\(C_T\)):

\[ C_T = C_F + v \cdot D \]

Where:

• \(C_F\) is the fixed cost.
• \(v\) is the variable cost per unit.
• \(D\) is the number of units produced.
• \(C_T\) is the total cost.
