Explanation
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 decreases, meaning that the same amount of money may not be able to buy as much in the future as it can today.
For example, if a product costs $100 today and prices increase over time, that same product could cost considerably more in the future. The exact change depends on the rate of inflation and how long the prices have been increasing.
Our Inflation Calculator allows you to estimate how the value of money can change over time based on an inflation rate. You can enter an amount of money, an inflation rate, and a number of years to see how much that amount could be worth in the future or what an amount from the past would be worth today.
Inflation is especially important when planning for long-term goals such as retirement, education, or buying a home. A savings goal that seems sufficient today may need to be larger in the future if prices continue to rise.
The calculator can also help demonstrate the difference between nominal value and purchasing power. A dollar may still be a dollar in the future, but its ability to purchase goods and services can change.
Keep in mind that inflation does not affect every product or service equally, and future inflation rates cannot be known with certainty. This calculator provides an estimate based on the rate and time period you enter.
Example
How Inflation Can Affect the Value of Money
Imagine you have $50,000 today and want to understand how inflation could affect its purchasing power over the next 20 years.
If you assume an average inflation rate of 3% per year, prices would generally become more expensive over that period. While you would still have $50,000 in nominal dollars if the money itself did not grow, its purchasing power would be lower than it is today.
Using the calculator, you can see what amount of money in the future would have approximately the same purchasing power as $50,000 today.
You can also work backward. For example, if you expect to need $100,000 for a future goal, the calculator can help estimate how much money you may need in the future to have purchasing power comparable to $100,000 today.
Try changing the assumptions to see how the results change:
- 2% inflation for 10 years
- 3% inflation for 20 years
- 3% inflation for 30 years
- 5% inflation for 20 years
These comparisons demonstrate why inflation is an important consideration when making long-term financial plans. Even seemingly small annual changes can have a significant effect when they compound over many years.
Remember: Inflation estimates are not predictions. Actual inflation can vary from year to year, and different goods and services can experience very different price changes.
FAQ
1. What is an inflation calculator?
An inflation calculator estimates how the purchasing power of money changes over time based on historical or expected inflation rates. It shows how much a specific amount of money from one year would be worth in another year after accounting for changes in the cost of goods and services.
2. How does inflation affect my money?
Inflation reduces the purchasing power of money over time, meaning the same amount of money can buy fewer goods and services in the future. For example, if inflation averages 3% per year, something that costs $100 today may cost significantly more in the future.
3. How is inflation calculated?
Inflation is calculated by comparing the change in prices of goods and services over time. An inflation calculator uses an inflation rate to estimate how prices increase or how much purchasing power decreases over a specific period.
4. How much will $10,000 be worth in 20 years with inflation?
The future value of $10,000 depends on the average inflation rate during that time period. For example, with a 3% annual inflation rate, $10,000 would have the purchasing power of roughly $5,500–$6,000 after 20 years. An inflation calculator can help estimate how much money may be needed in the future to maintain the same lifestyle.
5. Why is inflation important when planning for retirement?
Inflation is one of the biggest factors to consider when planning for retirement because your expenses may increase over decades. A retirement plan that ignores inflation may underestimate how much money you will need in the future. Including inflation helps create a more realistic retirement goal.
6. What is a good inflation rate to use for financial planning?
Many long-term financial plans use an estimated inflation rate of around 2%–3% per year, although actual inflation changes over time. The best rate to use depends on your goals, the time period being considered, and whether you are using historical data or making future projections.
