Money Time Inflation Calculator

Inflation erodes the purchasing power of money over time. This calculator helps you determine how much money will be worth in the future or how much it was worth in the past, adjusted for inflation.

How to Use This Calculator

To calculate the future or past value of money with inflation:

Enter the current amount of money you want to adjust.
Select whether you want to calculate future or past value.
Enter the number of years to adjust for.
Enter the annual inflation rate (as a percentage).
Click "Calculate" to see the adjusted amount.

The calculator will display the adjusted amount and show a chart of how the value changes over time.

The Inflation Formula

The formula for calculating future value with inflation is:

Future Value = Present Value × (1 + r)ⁿ

Where:

Future Value = The amount of money in the future
Present Value = The current amount of money
r = Annual inflation rate (as a decimal)
n = Number of years

For past value (inflation-adjusted present value), the formula is:

Past Value = Future Value ÷ (1 + r)ⁿ

These formulas account for compounding inflation over time.

Worked Example

Suppose you have $100 today and want to know how much it will be worth in 5 years with an annual inflation rate of 3%.

Future Value = $100 × (1 + 0.03)⁵ = $100 × 1.159274 = $115.93

After 5 years, $100 will be worth approximately $115.93.

This means that purchasing power will have increased by about 16% over 5 years at this inflation rate.

Interpreting Results

The results show how much money will be worth in the future or how much it was worth in the past, adjusted for inflation. Here's what the numbers mean:

Future Value: The amount of money you'll need today to have the same purchasing power in the future.
Past Value: The amount of money that would have the same purchasing power as your current amount today.

Remember that inflation rates can vary over time, so these calculations are estimates based on the rate you provide.
