What is the Inflation Calculator?
See how inflation raises future prices and erodes the purchasing power of your money. Inflation quietly reduces what money can buy, so long-term goals should be stated in future dollars, not today’s prices.
How to use the Inflation Calculator
- Enter your amount today, your inflation rate, your years.
- Results update automatically as you type; you can also press Calculate.
- Read the output: future cost of the same goods, future purchasing power of today’s amount, cumulative inflation.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With amount today = $1,000, inflation rate = 3 %, years = 10, the Inflation Calculator returns future cost of the same goods: $1,343.92; future purchasing power of today’s amount: $744.09; cumulative inflation: 34.39%.
Where the Inflation Calculator helps in real life
You expect a college course costing $20,000 today to be needed in ten years. At 3% inflation, the calculator shows what the same course could cost then.
You have $50,000 in cash savings earning almost nothing. Seeing its purchasing power after a decade of inflation helps explain why long-term money is usually invested.
Common mistakes to avoid
- Using one year’s unusually high or low inflation as a long-term rate.
- Assuming every price rises at the general rate — housing and education often differ.
- Comparing nominal returns without subtracting inflation.
- Forgetting that wages may also rise over time.
💡 Practical tip: Real return ≈ nominal return − inflation; a 5% return with 3% inflation grows purchasing power by about 2% a year.
Tips for better results
- Use a long-run average such as 2–3% for planning, and test a higher rate.
- Express retirement and education goals in future dollars.
- Compare investment returns with inflation to see your real return.
