# Consumer Price Index (CPI) Calculator

## Introduction

The Consumer Price Index (CPI) is a crucial economic indicator that measures changes in the average prices paid by consumers for a specific basket of goods and services over time. It is an essential tool for understanding inflation and its impact on the cost of living. This CPI calculator helps you determine the CPI percentage by comparing the cost of a market basket in the current period to its cost in a base period.

## How to Use

To calculate the Consumer Price Index using this calculator, follow these simple steps:

1. Enter the “Cost of Market Basket in Current Period” (Ct) in dollars.
2. Enter the “Cost of Market Basket in Base Period” (C0) in dollars.
3. Click the “Calculate CPI” button to obtain the CPI percentage.

## Formula

The formula used for calculating the Consumer Price Index (CPI) is as follows: CPI = (Ct / C0) * 100

## Example

Suppose you want to calculate the CPI for a specific year. The cost of the market basket in the current period is \$240, and the cost of the market basket in the base period is \$200. CPI = (\$240 / \$200) * 100 = 120
