What Is Inflation?

Inflation is the general increase in the prices of goods and services over time. As prices increase, the purchasing power of money generally decreases.

For example, if inflation averages 5% per year, something that costs 10,000 today would require more money in the future to purchase the same item.

Inflation Formula

Future Cost = Current Amount × (1 + Inflation Rate)^Years

The annual inflation rate is entered as a percentage and converted to a decimal before the calculation. The calculator applies the assumed rate over the selected number of years.

Purchasing Power Formula

Future Purchasing Power = Current Amount ÷ (1 + Inflation Rate)^Years

Purchasing power estimates how much the current amount would be worth in terms of today's purchasing power after the selected period, assuming the same inflation rate continues.

How to Use This Calculator

Inflation Calculator Example

Suppose an item costs 10,000 today and inflation averages 5% annually for 10 years. The estimated future cost would be:

10,000 × (1.05)¹⁰ ≈ 16,288.95

This means approximately 16,288.95 would be needed in 10 years to purchase something that costs 10,000 today, assuming a constant 5% annual inflation rate.

Why Inflation Matters

Inflation can affect household budgets, savings, investments, salaries, business costs and long-term financial planning. Understanding the potential effect of inflation can help you compare future costs with today's prices.

Important: This calculator provides an estimate based on the inflation rate you enter. Actual inflation rates can change from year to year, and future prices may differ significantly from the estimate. The result should not be treated as a prediction of actual future inflation or financial advice.

Frequently Asked Questions

What does an inflation calculator do?

It estimates how much money may be needed in the future to purchase something that costs a certain amount today, based on an assumed inflation rate.

Can I use a different inflation rate?

Yes. Enter any assumed annual inflation rate to create different estimates.

Does this calculator predict actual inflation?

No. It is an estimate based on the inflation rate you enter. Actual inflation can vary over time.

What does purchasing power mean?

Purchasing power refers to the amount of goods or services that a given amount of money can buy. Higher inflation can reduce purchasing power over time.

Can inflation be different every year?

Yes. Actual inflation can change from year to year. This calculator assumes that the annual inflation rate you enter remains constant throughout the selected period.
