What does this inflation calculator show for $100 from 2020 to 2030 at 2% inflation?

This calculator shows how much $100 in 2020 would be worth in 2030 if inflation averages 2% per year. It also helps you understand how much purchasing power that $100 loses over time. For example, at 2% annual inflation, $100 in 2020 would need to grow to about $121.90 by 2030 to maintain the same buying power.

What does the average annual inflation rate mean?

The average annual inflation rate represents the typical yearly increase in prices over the selected time period. For example, a 2% rate means prices are expected to rise by about 2% each year on average. The calculator compounds this rate annually to estimate the total impact over multiple years.

How is the future value calculated?

The calculator uses compound inflation, meaning each year’s increase builds on the previous year’s adjusted amount. It applies the formula: Future Value = Initial Amount × (1 + inflation rate)^number of years. This reflects how inflation accumulates over time rather than increasing in a straight line.

When should I use this inflation calculator?

Use this calculator when you want to understand how inflation affects savings, investments, or long-term financial plans. It’s especially helpful for comparing past and future dollar values or estimating how much money you’ll need to maintain purchasing power. For example, you can see what $100 today would need to become in 10 years to keep up with rising prices.

Does this calculator use actual historical inflation data?

No, this version uses the average annual inflation rate you enter rather than pulling real historical data automatically. If you enter 2%, it assumes inflation was exactly 2% every year between 2020 and 2030. For precise historical comparisons, you would need official CPI data for each year.

What is purchasing power loss and how is it shown?

Purchasing power loss refers to how much less you can buy with the same amount of money over time due to rising prices. The calculator shows this by comparing your initial amount to its inflation-adjusted future value. For example, if $100 grows to about $121.90 over 10 years at 2% inflation, it means prices have effectively risen by about 21.9% during that period.
