Inflation Calculator
Inflation Calculator
Measure the impact of inflation on your money using historical data or project future costs with custom rates.
This mode uses official U.S. CPI (Consumer Price Index) data to show how the value of the dollar has changed since 1913.
In 2024, it has the same buying power as
$181.88
Total Price Increase
81.9%
Average Annual Rate
-98.97%
Purchasing Power Note
Inflation reduces the **purchasing power** of each unit of currency. As prices rise, a single dollar buys fewer goods and services than it did in the past.
Worked Examples
In 1970, a worker earned $10,000 per year. They want to know what that salary would be worth in 2024 dollars to compare with their current earnings.
The calculator uses official CPI data to show that $10,000 in 1970 has the same buying power as approximately $80,721 today, a total inflation of over 700%.
A planner expects their monthly expenses to be $5,000 today, but they won't retire for 25 years. They assume a steady 3% inflation rate.
Using the "Forward" mode, the tool reveals that in 25 years, they will need $10,468 per month to maintain the exact same standard of living as $5,000 buys today.
Understand the True Value of Your Money with MyApexCalc
Have you ever heard your parents or grandparents talk about buying a gallon of gas for a quarter or a brand-new car for a few thousand dollars? It sounds unbelievable today, but those prices were completely normal for their time. This shift is due to inflation—the gradual decline in the purchasing power of a currency over time. Knowing how the value of money shifts across decades is crucial for long-term retirement planning, analyzing historical salaries, and evaluating long-term investment returns. Our free, interactive Inflation Calculator is engineered to act as a highly accurate dollar inflation calculator, letting you compare the purchasing power of money between any two years.
The Science of Purchasing Power: How the CPI Works
To calculate how much a dollar was worth in the past compared to today, economists rely on the Consumer Price Index (CPI). Issued monthly by the U.S. Bureau of Labor Statistics, the CPI acts as a dynamic inflation calendar, tracking the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services (including food, energy, housing, and medical care).
When you use our cpi calculator, the system compares the historical index values ($CPI$) of your starting year and your target year to compute the adjusted value of your money:
For example, if you want to find out how much $100 in 1980 is worth in today's money, the calculator divides the current CPI by the average CPI of 1980, then multiplies the result by 100. This math clearly highlights how much more cash you need today to purchase the exact same basket of goods and services.
