Enter all but one of the variables (A, UC, S, SC, F, FC) into the calculator to determine the crop input cost; this calculator can also evaluate any of the variables given the others are known.

## Crop Input Formula

The following formula is used to calculate the crop input cost:

CIC = (A * UC) + (S * SC) + (F * FC)

Variables:

- CIC is the crop input cost
- A is the amount of fertilizer used (in pounds)
- UC is the unit cost of fertilizer (per pound)
- S is the amount of seed used (in pounds)
- SC is the unit cost of seed (per pound)
- F is the amount of fuel used (in gallons)
- FC is the unit cost of fuel (per gallon)

To calculate the crop input cost, multiply the amount of fertilizer used by the unit cost of fertilizer, then add the result to the product of the amount of seed used and the unit cost of seed. Finally, add the product of the amount of fuel used and the unit cost of fuel to the previous result.

## What is a Crop Input?

A crop input refers to any product or resource used in the cultivation and management of crops, aimed at enhancing their growth and yield. These inputs can be categorized into two main types: direct and indirect inputs. Direct inputs include seeds, fertilizers, pesticides, and water, which are directly applied to the crops. Indirect inputs, on the other hand, include machinery, labor, and energy, which are used in the process of crop production but are not directly applied to the crops. The appropriate and efficient use of these inputs is crucial in achieving optimal crop yield and maintaining the sustainability of agricultural practices. The choice and amount of crop inputs used can significantly affect the quality of the crops, the cost of production, and the environmental impact of farming.

## How to Calculate Crop Input?

The following steps outline how to calculate the Crop Input Ratio.

- First, determine the total cost of crop inputs ($).
- Next, determine the total revenue generated from the crop ($).
- Next, gather the formula from above = CIR = TC / TR.
- Finally, calculate the Crop Input Ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

total cost of crop inputs ($) = 500

total revenue generated from the crop ($) = 1200
