Inflation
Inflation is the rate at which the general level of prices for goods and services rises over time, eroding purchasing power. It is typically measured by the Consumer Price Index (CPI), which tracks the cost of a basket of common goods and services. Central banks target moderate inflation (typically 2%) as a sign of a healthy economy.
Example
If the inflation rate is 3% per year, an item that costs $100 today will cost approximately $103 in one year. Over 10 years at 3% inflation, that same item would cost about $134. This means your savings need to grow at least at the inflation rate to maintain purchasing power.
Frequently Asked Questions
How does inflation affect my salary?
If your salary increases by less than the inflation rate, your real income (purchasing power) is decreasing. When negotiating raises or evaluating job offers, consider whether the increase keeps pace with or exceeds inflation.
How do I protect my savings from inflation?
Investing in assets that historically outpace inflation (stocks, real estate, TIPS) can protect your purchasing power. Keeping large amounts in low-interest savings accounts means your money loses value over time. Use our investment calculator to model growth against inflation.
