What Is an Inflation Calculator?
An inflation calculator shows how the purchasing power of money changes over time due to inflation. It answers questions like "What would $1,000 in 2000 be worth today?" or "How much will I need in 20 years to maintain today's standard of living?" Inflation erodes purchasing power — meaning the same amount of money buys less goods and services as prices rise over time.
How to Use
- Amount: the original monetary value
- From year / To year: the time period to calculate over
- Annual inflation rate: average yearly inflation (use presets or enter a custom rate)
- The result shows the equivalent value adjusted for inflation and yearly breakdown
How Inflation Is Calculated
- Future value: Amount × (1 + rate/100)^years — how much you need in the future to equal today's purchasing power
- Past value: Amount / (1 + rate/100)^years — what past money is worth in today's terms
- Real interest rate ≈ Nominal rate − Inflation rate (Fisher equation)
FAQ
What is a typical inflation rate?
Most central banks target 2% annual inflation as a healthy rate. The US averaged about 2.5% from 1990–2020. During 2021–2023, inflation spiked to 5–9% in many countries due to post-pandemic supply chain disruptions and monetary policy.
What is the difference between nominal and real value?
Nominal value is the face value of money — the number on the banknote. Real value adjusts for inflation and reflects actual purchasing power. $100 in 2000 had more real purchasing power than $100 in 2024 because prices have risen.
What is the Rule of 70?
The Rule of 70 estimates how many years it takes for the purchasing power of money to halve: Years ≈ 70 / inflation rate. At 2% inflation, purchasing power halves in ~35 years. At 7% inflation, it halves in just ~10 years.
How does inflation affect savings and investments?
If your savings earn a lower return than inflation, your real purchasing power is shrinking even if the nominal balance grows. For example, earning 1% on savings while inflation is 3% means you are effectively losing 2% of purchasing power per year.
