Inflation is one of the most important economic forces affecting your finances. Over time, rising prices reduce the purchasing power of your money—what cost $100 a few years ago may cost $110 or more today. Our free inflation calculator (purchasing power calculator) uses official U.S. Bureau of Labor Statistics (BLS) CPI-U data to show you how much a past or future dollar amount is worth in today's terms, or in any other year. Whether you're planning retirement with our retirement calculator, comparing salaries across decades, or understanding why your salary "doesn't go as far," this tool helps you see the real value of money over time.
Inflation is the rate at which the general level of prices for goods and services rises over time. When inflation is positive, each dollar you hold buys fewer goods and services in the future. For example, if inflation averages 3% per year, $1,000 today will have the same purchasing power as about $1,030 in one year—meaning you need $1,030 next year to buy what $1,000 buys today. Central banks, such as the Federal Reserve in the United States, aim to keep inflation moderate (often around 2%) to support stable economic growth without eroding savings too quickly.
Purchasing power is the amount of goods or services that one unit of money can buy. When inflation rises, purchasing power falls: the same nominal amount of money buys less. A purchasing power calculator like ours answers questions such as: "How much would $10,000 in 2020 be worth in 2026?" or "What would my 1990 salary be in today's dollars?" By converting amounts across years using historical CPI data, you get a fair comparison of real value and can make better financial and career decisions.
Our inflation calculator uses the U.S. Consumer Price Index for All Urban Consumers (CPI-U), published by the Bureau of Labor Statistics. The CPI measures the average change over time in prices paid by urban consumers for a basket of goods and services. We apply the compound inflation formula: to find the equivalent amount in a different year, we multiply (or divide) by the cumulative inflation factor between the two years. For example, if inflation was 2% in year one and 3% in year two, $100 in year zero becomes $100 × 1.02 × 1.03 in year two. Our tool does this automatically for any start year, end year, and amount you enter.
An inflation or purchasing power calculator is useful for many real-life situations. When negotiating salary, compare your offer to past salaries in "today's dollars" so you see whether you're really getting a raise. When planning retirement, use our retirement calculator alongside this tool to see how much income you'll need in future dollars. When reviewing long-term contracts, investments, or savings goals, converting historical and future amounts to the same year helps you set realistic targets. Even for everyday awareness, seeing how much $50,000 in 2000 equals in 2026 can clarify why "money doesn't go as far" and why saving and investing are essential.
Using our free inflation calculator is straightforward. First, enter the dollar amount you want to convert—for example, 10,000 or 50,000. Next, choose the start year (the year that amount is from) and the end year (the year you want the equivalent value in). Click Calculate, and the tool will show you the amount in end-year dollars. You can run the calculation in either direction: from past to present, or from present to future, or between any two years within our data range. The result is based on BLS annual CPI-U inflation rates applied in compound form.
Suppose you earned $60,000 in 2020 and want to know what that salary would be in 2026 dollars. Enter 60000, start year 2020, end year 2026. The calculator applies cumulative CPI inflation from 2020 through 2025 (and estimated 2026) and shows the equivalent salary in 2026. If the result is around $72,000, that means you would need a salary of about $72,000 in 2026 to have the same purchasing power as $60,000 in 2020. Use our salary calculator to see how that translates to take-home pay.
You're planning to retire in 2030 and want to have the same purchasing power as $1,000,000 today. Use the inflation calculator with amount 1000000, start year 2026, end year 2030 (or the latest year available). The result is the nominal amount you'd need in 2030 to match $1 million in today's buying power. This helps you set a target for your retirement calculator and investment calculator.
A relative says that in 1990 they bought a car for $15,000. You want to know what that is in today's dollars. Enter 15000, start year 1990 (if available in our range), end year 2026. The calculator shows the equivalent amount in 2026 dollars, so you can compare that to current car prices and understand how car costs have changed in real terms.
Our inflation calculator relies on the Consumer Price Index for All Urban Consumers (CPI-U), produced by the U.S. Bureau of Labor Statistics (BLS). This index reflects spending patterns of urban households and is widely used for cost-of-living adjustments, contract escalation, and economic analysis. Data is updated when new annual figures are released. For years that have not yet been reported, we may use reasonable estimates; such estimates are labeled and should be updated when official data is available. No single index captures every person's experience—your personal inflation rate may differ if you spend more or less on housing, healthcare, or education than the average basket—but CPI-U is the standard reference for broad purchasing power over time.
Inflation affects savings, investments, and debt. Money in a low-interest savings account may earn less than inflation, so your real (inflation-adjusted) return can be negative. Investments that historically outpace inflation, such as stocks, can help preserve purchasing power over the long term; use our investment calculator to project growth. Fixed-rate debt becomes easier to repay over time in real terms because you pay with "cheaper" future dollars. Understanding inflation helps you choose the right mix of savings, investments, and debt and set realistic goals in our compound interest calculator and savings calculator.
When using an inflation calculator, avoid these pitfalls. First, don't confuse nominal and real amounts: a raise from $50,000 to $52,000 might not be a "real" raise if inflation was 5%. Second, don't assume one year's inflation applies to long periods—inflation compounds, so multi-year calculations must use cumulative factors. Third, remember that CPI is an average; your personal inflation rate may differ. Fourth, for future years, official data may not exist yet, so treat results that depend on estimated future inflation as illustrative. Finally, use the calculator as a planning tool, not as the sole basis for legal or contractual decisions; when in doubt, consult a financial or legal professional.
When planning your finances, always consider inflation. Set retirement and savings goals in today's dollars, then use the inflation calculator to see what nominal amount you'll need in the future. When comparing job offers or salary history, convert everything to the same year so you compare apples to apples. When evaluating long-term investments, focus on real (inflation-adjusted) returns. Keep an emergency fund in a liquid account even if it doesn't beat inflation—liquidity has value. Use our budget calculator and salary calculator to align your daily budget with your long-term, inflation-aware goals.
Our inflation calculator works well with other finance tools on Calculator360Pro. Use the retirement calculator to see how much you need to save in future dollars; the investment calculator to project nominal growth; the compound interest calculator to see how compounding and inflation interact; and the salary calculator to understand take-home pay in current dollars.

Inflation steadily erodes the purchasing power of money, so comparing dollar amounts across years requires adjusting for inflation. Our free inflation and purchasing power calculator uses BLS CPI-U data to give you quick, clear equivalents between any two years. Use it to compare salaries, plan retirement, understand historical prices, and set realistic financial goals. Combined with our other calculators—retirement, investment, salary, and savings—you can build a full picture of your finances in real terms and make decisions that keep your purchasing power on track over time.

The calculator uses U.S. Bureau of Labor Statistics (BLS) annual CPI-U inflation rates. You enter an amount and two years (start and end). It applies compound inflation between those years to show the equivalent purchasing power. For example, $10,000 in 2020 might equal about $12,000 in 2026 depending on cumulative inflation.
Purchasing power is how much goods or services your money can buy. When inflation rises, the same dollar amount buys less over time. Our calculator shows what a past or future amount would be worth in another year's dollars, so you can compare salaries, savings, and prices in real terms.
We use the U.S. Consumer Price Index for All Urban Consumers (CPI-U) from the Bureau of Labor Statistics (BLS). Annual rates are applied in compound form between your chosen years. Data is updated when BLS releases new figures; future years may use estimates until official data is available.
If your salary increase is smaller than inflation, your real (inflation-adjusted) purchasing power falls. For example, a 2% raise when inflation is 4% means you can buy less than the year before. Use our calculator to convert your past salary into today's dollars and compare with your current pay.
Enter the older salary amount, set the start year to when that salary was earned, and set the end year to the more recent year (or today). The result is that salary in end-year dollars. You can then compare it fairly to a current salary. Use our salary calculator to see take-home pay for any amount.
