How it works
Inflation erodes purchasing power over time. The formula is: Future Value = Present Amount / (1 + Rate)^Years. This shows what your current money will be "worth" in real terms after a given period. A 3% annual inflation rate means prices roughly double every 24 years, so $10,000 today would only buy about $7,441 worth of goods in 10 years.
Practical example
You have $10,000 today and inflation averages 3% per year. After 10 years, your $10,000 will only buy what $7,441 buys today — a loss of $2,559 in purchasing power. After 20 years, it drops to $5,537. This is why keeping large amounts in a zero-interest account loses value over time.
Frequently asked questions
Reusable FAQ content keeps each calculator page richer for users and search engines.
Is a fixed inflation rate realistic?
Inflation varies year to year. This gives an estimate based on a constant average rate.
Does it account for investments?
No. This only models the effect of inflation on purchasing power, not investment returns.
What is a typical inflation rate?
In most developed countries, central banks target around 2% annual inflation. During economic disruptions, it can spike to 5-10% or higher.
How do I protect against inflation?
Investing in assets that historically outpace inflation — stocks, real estate, inflation-protected bonds (TIPS) — helps preserve purchasing power.
