Calculate Inflation Rate from CPI

This calculator helps you determine the annual inflation rate between two periods using the Consumer Price Index (CPI). Inflation measures the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling.

The formula used is: Inflation Rate = ((CPI in Later Period – CPI in Earlier Period) / CPI in Earlier Period) * 100

function calculateInflation() { var cpiEarlier = parseFloat(document.getElementById("cpi_earlier").value); var cpiLater = parseFloat(document.getElementById("cpi_later").value); var resultDiv = document.getElementById("result"); if (isNaN(cpiEarlier) || isNaN(cpiLater)) { resultDiv.innerHTML = "Please enter valid numbers for both CPI values."; return; } if (cpiEarlier <= 0) { resultDiv.innerHTML = "CPI in the earlier period must be a positive number."; return; } var inflationRate = ((cpiLater – cpiEarlier) / cpiEarlier) * 100; resultDiv.innerHTML = "Inflation Rate: " + inflationRate.toFixed(2) + "%"; }

Understanding CPI and Inflation Rate

The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them. Changes in the CPI are used to measure inflation, which is the rate of change of prices over time.

To calculate the inflation rate between two periods, you need the CPI values for both periods. For example, if the CPI was 250.00 in January 2022 and 265.00 in January 2023, you can use this calculator to find the annual inflation rate.

Example Calculation:

Let's say:

  • CPI in Earlier Period (e.g., January 2022): 250.00
  • CPI in Later Period (e.g., January 2023): 265.00

Using the formula:

Inflation Rate = ((265.00 – 250.00) / 250.00) * 100

Inflation Rate = (15.00 / 250.00) * 100

Inflation Rate = 0.06 * 100

Inflation Rate = 6.00%

This means that, on average, prices increased by 6.00% between January 2022 and January 2023.
