Calculate how inflation affects the value of money over time — see the future equivalent of an amount, or how much purchasing power is lost.
This tool calculates how the purchasing power of money changes over time due to inflation, showing what a past amount would be worth today, or what a current amount will need to be in the future to maintain the same purchasing power.
Future Value = Present Value × (1 + inflation rate)ⁿ, where n is the number of years. To adjust a past amount to today's value, the same formula applies using the cumulative inflation rate over the elapsed period.
Enter an amount, the starting year (or assumed annual inflation rate), and the target year, and the calculator returns the inflation-adjusted equivalent value.
Example: $100 in 2000, adjusted for an average inflation rate of roughly 2.5% per year, would be equivalent to approximately $185-190 in today's dollars, reflecting the cumulative loss of purchasing power over that period.
Why does inflation matter for long-term financial planning? Inflation erodes the purchasing power of money over time, meaning a fixed amount of savings will buy less in the future than it does today, which is why long-term financial goals (like retirement) need to account for expected inflation, not just nominal dollar amounts.
What's a typical long-term average inflation rate to use in projections? Many long-term financial projections use a historical average of around 2-3% annually for developed economies, though actual inflation varies significantly year to year and by country, so this should be treated as a general planning assumption rather than a precise prediction.
What's the difference between nominal and real (inflation-adjusted) values? Nominal value is the raw dollar amount without adjustment, while real value accounts for inflation's effect on purchasing power — comparing real values across time gives a more accurate picture of actual economic change than comparing nominal figures alone.
How does inflation affect fixed-income investments like bonds? Inflation can erode the real return of fixed-income investments, since the fixed interest payments don't adjust for rising prices, which is why some investors consider inflation-protected securities as part of a diversified portfolio.
Can inflation calculations help understand historical prices? Yes, this type of calculation is commonly used to understand how much a historical price (like a house price or salary from decades ago) would be equivalent to in today's dollars, providing useful context for historical comparisons.
