Enter the total change in output and the total change in input into the calculator. The calculate will evaluate the marginal product.

## Marginal Product Formula

The following equation is used to calculate the marginal product of a produced good.

MP = O / I

- Where MP is the marginal product
- I is the change in input
- O is the change in output

## Marginal Product Definition

A marginal product is the ratio of the change in output with a corresponding change in input of a good or service. For example how the out put would change with a doubling of the input.
