Inflation Impact Calculator
See how inflation erodes purchasing power over time and what your money will be worth in the future.
The impact of inflation compounds over time, much like interest. At a modest 3% annual inflation rate, $100,000 in savings will have the purchasing power of roughly $74,400 after ten years. That means you would need $134,400 in nominal terms just to maintain the same buying power you had at the start. Over 20 years at the same rate, the erosion is even more dramatic: your $100,000 would purchase only about $55,400 worth of goods in today's terms.
This is why simply saving money in a low-interest bank account can actually result in a net loss of wealth when inflation is considered. If your savings earn 1% interest but inflation runs at 3%, you are losing 2% of real purchasing power every year. Understanding this dynamic is essential for retirement planning, long-term savings decisions, and salary negotiations.
Central banks around the world target inflation rates of about 2% to 3%, but actual rates fluctuate and can spike during economic disruptions. This calculator shows you the real purchasing power of any amount after accounting for a given inflation rate over your chosen time horizon, helping you plan ahead and ensure your money retains its value.

FAQ
How does inflation reduce purchasing power?
Inflation increases the general price level of goods and services over time. If prices rise 3% per year, something that costs $100 today will cost $103 next year. Your money does not shrink in nominal terms, but it buys less. Over many years this effect compounds, significantly reducing what a fixed amount of money can purchase.
What is a realistic inflation rate to use?
In the United States, the long-term historical average inflation rate is approximately 3% per year. The Federal Reserve targets about 2% annually. For conservative planning, 3% is commonly used. During periods of high inflation, rates can exceed 5% to 8%. Use the rate that best reflects your planning horizon and economic outlook.
How can I protect my money from inflation?
Common strategies to hedge against inflation include investing in assets that historically outpace inflation, such as diversified stock portfolios, real estate, and Treasury Inflation-Protected Securities (TIPS). Keeping all savings in a low-interest bank account typically results in a loss of real purchasing power over time.
