# Marginal Profit Function Calculator Online

The Marginal Profit Function Calculator computes the additional profit earned from the sale of an extra unit of a product. By providing the total revenue and total cost functions, this calculator helps businesses identify the optimal production level to maximize profits. It simplifies complex calculations, saving time and ensuring accuracy.

## Formula of Marginal Profit Function Calculator

To calculate the marginal profit, follow these steps:

Profit Function (P):

Profit (P) is calculated as: P(x) = R(x) - C(x)

where: R(x) is the total revenue function C(x) is the total cost function x is the number of units produced and sold

Marginal Profit Function (MP):

The marginal profit function is the derivative of the profit function with respect to x: MP(x) = dP(x) / dx

Given that the profit function P(x) is the difference between revenue and cost, the marginal profit function can be written as: MP(x) = d[R(x) - C(x)] / dx

Since differentiation is linear, this simplifies to: MP(x) = dR(x) / dx - dC(x) / dx

Therefore: MP(x) = MR(x) - MC(x)

where: MR(x) is the marginal revenue function, the derivative of the total revenue function MC(x) is the marginal cost function, the derivative of the total cost function

## Example of Marginal Profit Function Calculator

Let's consider a practical example to illustrate how to use the Marginal Profit Function Calculator.

Suppose a company produces and sells a product, and the total revenue function is R(x) = 100x - 0.5x^2 and the total cost function is C(x) = 20x + 0.2x^2.

1. Calculate the marginal revenue MR(x): MR(x) = d(100x - 0.5x^2) / dx = 100 - x
2. Calculate the marginal cost MC(x): MC(x) = d(20x + 0.2x^2) / dx = 20 + 0.4x
3. Calculate the marginal profit MP(x): MP(x) = MR(x) - MC(x) = (100 - x) - (20 + 0.4x) = 80 - 1.4x

Therefore, the marginal profit function is MP(x) = 80 - 1.4x. This function helps the company determine the additional profit for producing one more unit.
