Inflation Calculator

An inflation calculator shows how inflation erodes the purchasing power of money over time. It helps you understand how much more money you'll need in the future to buy the same goods and services you can afford today, and how much your current money will effectively be worth in the future.

Inflation is the gradual increase in the general price level of goods and services. Even a modest annual inflation rate of 2-3% can significantly reduce your purchasing power over decades. This calculator quantifies that impact so you can plan your savings and investments accordingly.

Whether you're planning for retirement, negotiating a salary, or setting long-term financial goals, understanding inflation is crucial. This tool shows three key metrics: the future amount needed to match today's purchasing power, how much purchasing power is lost, and what today's money will effectively be worth in the future.

1. Enter the current amount — The dollar amount you want to analyze.
2. Set the inflation rate — The expected annual inflation rate (historically around 2-3% in the US).
3. Enter the number of years — The time period to project forward.
4. Review results — See the future value needed, purchasing power lost, and effective value of today's money.

The inflation calculation uses the compound growth formula:

Future Value Needed = Current Amount x (1 + Inflation Rate)^Years

Effective Value = Current Amount / (1 + Inflation Rate)^Years

Example: $10,000 at 3% inflation for 10 years → Future value needed = $10,000 x (1.03)^10 = $13,439. Your $10,000 will only buy what $7,441 buys today.
