What is purchasing power and inflation?
Inflation is the rate at which the general price level of goods and services rises, causing purchasing power to fall. Purchasing power is the quantity of goods or services a unit of currency can buy at a given time.
Understanding purchasing power helps you evaluate whether your salary, savings, or investments are truly growing in real terms. An investment that returns 5% while inflation runs at 4% is only giving you 1% real growth.
How to use this calculator
- 1Enter the original amount — Input the amount of money you want to evaluate.
- 2Set the start year — Choose the year the original amount was spent or saved.
- 3Set the end year — Choose the comparison year, typically the current year.
- 4Review purchasing power — See what the original amount is worth in today's terms, and vice versa.
Formula & example
Future Value = Present Value x (1 + Inflation Rate)^Years | Present Value = Future Value / (1 + Inflation Rate)^Years
Example: An amount of 10,000 in 2005 at 3% average inflation is worth approximately 18,061 in 2025. To have the same purchasing power as 10,000 today, in 2005 would have cost only 5,537.

Frequently asked questions
What is the difference between CPI and core inflation?+
CPI measures the change in prices of a broad basket of goods and services including food and energy. Core inflation strips out food and energy prices, which are volatile, to show the underlying inflation trend.
How does inflation affect savings?+
If your savings account earns 2% but inflation is 3%, you are losing purchasing power at 1% per year. After 10 years, your real wealth is lower even though the nominal balance has grown.
What is hyperinflation?+
Hyperinflation is extremely rapid inflation, often defined as exceeding 50% per month. It destroys the value of money and savings rapidly. Historical examples include Germany in the 1920s and Zimbabwe in the 2000s.
How is inflation measured?+
Most countries use a Consumer Price Index calculated by a statistics office. It tracks the price changes of a representative basket of goods and services bought by households.
Does inflation affect all goods equally?+
No. Some goods like technology tend to get cheaper over time while others like education, healthcare, and housing often inflate faster than the general CPI rate.
