How to Use Our Inflation Calculator
Our tool is simple. To find the buying power of a certain amount of money between two years, you only need three pieces of information.
-
Initial Amount: Enter the dollar amount you want to analyze. For example, if you want to know what a $50,000 salary from 1995 is worth today, you would enter “50000”.
-
Start Year: This is the year your initial amount is from. The calculator uses data from 1913 to the present.
-
End Year: This is the year you want to compare to. It can be in the past or the present.
Understanding Your Results
The number our calculator provides isn’t just an estimate; it’s a calculation of equivalent purchasing power. For example, if you find that $1,000 in 1980 is equivalent to $3,700 today, it means you would need $3,700 in the current year to buy the same “basket” of goods and services that $1,000 could buy in 1980.
How is This Calculated? The CPI
This calculator works by using the Consumer Price Index (CPI), the most widely used measure of inflation. The CPI is compiled and published monthly by the U.S. Bureau of Labor Statistics (BLS). It represents the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services, including food, housing, transportation, and medical care.
The formula used is:
Final Value=Initial Value×(Start Year CPIEnd Year CPI)

Frequently Asked Questions
What exactly is inflation?
Inflation is the rate at which the general level of prices for goods and services rises, leading to a fall in the purchasing power of currency. In simple terms, your dollar buys you less than it did before. Central banks aim for a steady, low rate of inflation (typically around 2%) to encourage spending and investment and to keep the economy growing smoothly.
How does inflation affect my savings and investments?
Inflation directly erodes the value of your savings. If your money is in a savings account earning 1% interest, but inflation is running at 3%, the “real” value of your savings is actually decreasing by 2% per year. This is why investing is critical for long-term goals like retirement. To grow your wealth, your investment returns must be higher than the rate of inflation. This concept is known as the “real rate of return.”
What causes inflation?
There are two primary causes:
-
Demand-Pull Inflation: This happens when demand for goods and services outstrips the economy’s ability to produce them. Too much money is chasing too few goods, which pushes prices up. This can be caused by strong economic growth, increased government spending, or tax cuts that put more money in consumers’ pockets.
-
Cost-Push Inflation: This occurs when the costs of production increase. For example, if the price of oil rises, the cost to transport goods increases, and those costs are passed on to consumers in the form of higher prices. Supply chain disruptions or increases in wages can also lead to cost-push inflation.
What is the difference between inflation and deflation?
Deflation is the opposite of inflation. It’s a decrease in the general price level of goods and services. While falling prices might sound good, deflation is often very dangerous for an economy. When people expect prices to fall, they delay purchases, hoping for a better deal later. This can lead to a sharp drop in demand, which in turn can cause a recession, job losses, and falling wages.
Can I use this calculator to predict future inflation?
No, this is a historical calculator. It uses official data from the past to show you how value has already changed. While financial institutions make forecasts about future inflation, they are only educated guesses. No tool can predict future inflation with certainty because it is influenced by many unpredictable events, from geopolitical conflicts to natural disasters.
How much money will I need for retirement with inflation?
This is one of the most important questions in financial planning. Let’s use a concrete example.
Concrete Example: Imagine you are 35 years old and plan to retire in 30 years at age 65. You live comfortably on $60,000 per year today. How much will you need per year in retirement to maintain that same lifestyle?
Assuming an average annual inflation rate of 3% (a common long-term estimate):
-
You can’t use our calculator directly for this, as it uses historical CPI. But the principle is the same. You’d need a future value calculator.
-
The math shows that in 30 years, you would need approximately $145,600 per year to have the same purchasing power that $60,000 gives you today. This demonstrates why simply saving cash is not enough for retirement; you must invest it to outpace inflation.
Is the CPI an accurate measure of my personal inflation?
The CPI is a broad average. It may not perfectly reflect your personal situation. For example, if the price of gasoline rises sharply but you don’t own a car, your personal inflation rate won’t be as affected as the national average. Likewise, if your rent or healthcare costs increase faster than the average, your personal inflation rate could be higher. The CPI is an excellent and reliable benchmark, but individual experiences will vary.
