Inflation Calculator
Use our free Inflation Calculator to estimate how inflation can change the value and purchasing power of money over time. Enter an amount, expected annual inflation rate, and number of years to see the estimated future cost.

Future Cost Breakdown
What Is Inflation?
Inflation is the general increase in prices of goods and services over time. When prices rise, the purchasing power of a fixed amount of money generally decreases. In other words, the same amount of money may buy fewer goods and services in the future.
For example, if something costs $100 today and prices increase by 3% per year, the same item could cost substantially more after several years. The exact change depends on the inflation rate experienced during that period.
How an Inflation Calculator Works
This calculator uses a compound inflation formula to estimate the future cost of an item or the amount of money required to maintain the same purchasing power. It applies the annual inflation rate over the number of years entered.
The calculation is hypothetical. Actual inflation can change from year to year and different categories of expenses can experience very different price increases.
Why Inflation Matters for Retirement Planning
Inflation is particularly important when planning for long-term financial goals. A retirement budget that appears sufficient today may not provide the same purchasing power decades from now.
For example, housing, healthcare, food, transportation, and education costs may increase at different rates. Long-term financial planning should therefore consider the potential effect of inflation on future expenses.
Inflation and Investments
Investors often consider inflation when evaluating investment returns. A nominal return does not necessarily represent an increase in purchasing power because inflation reduces the real value of money.
For long-term planning, it can be useful to compare hypothetical investment returns with hypothetical inflation rates. However, investment returns are uncertain and actual inflation can vary considerably.
Frequently Asked Questions
How does inflation reduce purchasing power?
When prices increase, the same amount of money can generally purchase fewer goods and services than before.
What inflation rate should I use?
There is no guaranteed future inflation rate. You can test multiple hypothetical rates to understand how different scenarios could affect future costs.
Does inflation affect retirement savings?
Yes. Inflation can reduce the purchasing power of retirement savings, which is why long-term retirement planning often considers future living costs.
