Understand the True Value of Your Money Over Time

Our Inflation Calculator uses historical Consumer Price Index (CPI) data to show how the purchasing power of money has changed over the years, helping you understand the real value of your savings and investments.

What is an Inflation Calculator?

An Inflation Calculator is a financial tool that adjusts the value of money for inflation over different time periods. It helps you understand what a certain amount of money in the past would be worth today, or what a current amount will be worth in the future. This is crucial for long-term financial planning, such as retirement savings, as it shows how the cost of living impacts the real value of your money.

How It Works: The CPI Formula

The calculator uses the Consumer Price Index (CPI) for historical calculations:

Current Dollars = Past Dollars × (Current CPI / Past CPI)
  1. Enter an Amount: Input the dollar amount you want to convert.
  2. Select a Start Year: Choose the year the dollar amount is from.
  3. Select an End Year: Choose the year you want to convert the value to.
  4. Calculate: The tool uses historical CPI data to show the equivalent value in the end year's dollars.

Interpreting the Results: Your Money's Buying Power

The result shows you the **equivalent buying power**. For example, if the calculator shows that $100 in 1990 is equivalent to $235 today, it means you would need $235 today to buy the same "basket" of goods and services that $100 could buy in 1990. The **Total Inflation** percentage shows the cumulative increase in prices between the two years.

Common Inflation Myths

  1. Myth 1: Inflation is always bad. While high inflation is harmful, a small, steady amount of inflation (around 2%) is generally considered a sign of a healthy, growing economy by central banks. It encourages spending and investment rather than hoarding cash.
  2. Myth 2: My salary increase is all real gain. If your salary increases by 5% but inflation is 3%, your "real" increase in purchasing power is only 2%. It's important to consider inflation when evaluating raises.
  3. Myth 3: Inflation affects everyone equally. Inflation can disproportionately affect those on fixed incomes, like retirees, whose purchasing power decreases as prices rise. It can also impact different sectors of the economy differently.

Frequently Asked Questions

How do you calculate the value of money with inflation?

To calculate the future value of money considering inflation, you can use the formula: Future Value = Present Value × (1 + Inflation Rate)ⁿ, where 'n' is the number of years. To find a past value, you'd use Present Value = Future Value / (1 + Inflation Rate)ⁿ. Our Inflation Calculator uses historical CPI data for past calculations and this formula for future projections.

What is the Consumer Price Index (CPI)?

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 a key way of measuring inflation and deflation.

How does inflation affect my savings?

Inflation erodes the purchasing power of your savings over time. If the interest rate on your savings account is lower than the rate of inflation, the real value of your money is actually decreasing. For example, if you have $100 and inflation is 3%, your money will only be able to buy $97 worth of goods and services next year.

What was the value of $100 in 1980?

Using historical CPI data, $100 in 1980 had the same buying power as approximately $370 in 2023. You can use our calculator to compare values between different years.

Tips for Protecting Your Savings

  • Invest for Growth: Aim for an investment return rate that is higher than the rate of inflation. Stocks and real estate have historically outpaced inflation over the long term.
  • Consider Inflation-Protected Securities: Investments like Treasury Inflation-Protected Securities (TIPS) are designed to increase in value with inflation.
  • Review Your Budget: As prices rise, periodically review your budget to see where costs have increased and where you can adjust your spending.
  • Negotiate Your Salary: Advocate for regular cost-of-living adjustments to your salary to maintain your purchasing power.
