Inflation is a fundamental economic concept that describes the gradual increase in prices for goods and services over time. As prices rise, each unit of currency buys a smaller percentage of a good or service. This means inflation reduces your purchasing power, making it a critical factor in long-term financial planning.
Governments track inflation using indexes such as the **Consumer Price Index (CPI)**. The CPI monitors the average price changes of a basket of consumer goods and services (including food, housing, energy, and healthcare) over time.
While a low level of inflation (usually around 2% annually) is considered a sign of a healthy growing economy, high inflation can erode savings quickly. To see how compound interest can help your savings keep pace with inflation, see our interest calculator.
The formula to calculate the future price of a good based on a constant inflation rate is: - **Future Price = Current Price × (1 + Inflation Rate)^Years** - **Inflation Rate:** Expressed as a decimal (e.g. 3% is 0.03). - **Years:** The time period.
To see how this compounds on savings accounts or investment portfolios, see our investment growth planner.
To prevent your savings from losing value over time: - Avoid Excess Cash: Keeping large amounts of cash in low-interest savings accounts guarantees a loss of purchasing power. - Invest in Real Assets: Equities, real estate, and commodities historically act as hedges against inflation because their values tend to rise alongside prices.

Suppose a basket of groceries costs $100 today. If inflation averages 3% per year for 10 years: - Future Cost = 100 × (1 + 0.03)^10 - Future Cost = 100 × 1.3439 = $134.39.
You would need $134.39 in 10 years to buy the same groceries. If you need to make simple math calculations, try our everyday daily math helper.
While inflation hurts savers, it can benefit borrowers. Fixed monthly loan payments remain the same, but the "real" value of the money used to pay the debt decreases as inflation rises.
To manage your total monthly debt payments, try our payment calculator. For home-specific loans, see our mortgage calculator or check our general loan calculator.
Analyzing how inflation affects your future purchasing power is key to maintaining a healthy financial profile. It allows you to set realistic targets for savings and investments.
