Frequently asked questions
Complete guide to Inflation Calculator
What does an inflation calculator do?
An inflation calculator shows how much a sum of money today would be worth in the future at a given inflation rate. Equivalently, it shows how much purchasing power you would need in the future to match what a certain amount buys today. Inflation erodes the value of cash over time: $10,000 today might buy less in 10 years if prices rise.
Enter the amount you have today, an assumed annual inflation rate (e.g. 3% is often used for long-term planning), and the number of years. The calculator returns the future value — the amount you would need in the future to have the same purchasing power. This helps with retirement planning, salary negotiations, and setting long-term savings goals.
Why inflation matters for your finances
- Retirement: Your retirement corpus must account for inflation; costs will be higher in 20–30 years.
- Salary: Raises that do not beat inflation mean your real (inflation-adjusted) income is falling.
- Savings: Money in low-interest accounts may grow slower than inflation, losing purchasing power.
- Investments: Equity and real estate have historically outpaced inflation over the long term.
Typical inflation assumptions
Central banks in many countries target inflation around 2% per year. Historical averages in the US and elsewhere have varied; 3% is a common assumption for long-term planning. Use this calculator with different rates to see how sensitive your goals are to inflation.
