How the inflationary millionaires calculator works

It compounds your target sum forward at the inflation rate to show the future amount needed to match today’s buying power, and discounts it the other way to show what that target will actually buy later.

Worked example

Worked example: with target amount (today’s dollars) of $1,000,000, annual inflation of 3.00% and years from now of 30, the inflationary millionaires calculator shows to match $1,000,000 today, you’ll need of $2,427,262.

The formula

Future sum needed = target × (1 + inflation)^years. Future buying power of the target = target ÷ (1 + inflation)^years.

Frequently asked

Questions about the inflationary millionaires

Will a million dollars be enough in the future?

It will buy less than it does today. At 3% inflation, you would need far more than $1 million in 30 years to match its current purchasing power, as the calculator shows.

Should I set goals in today’s or future dollars?

Plan in future dollars. Targeting a round number like "$1 million" without adjusting for inflation can leave you well short of the lifestyle you imagined.

How fast does inflation erode a fixed sum?

Faster than most expect — at 3%, money loses roughly a quarter of its value in a decade and about half over 24 years.

Is the Inflationary Millionaires free to use?

Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
