What is future value vs today's value after inflation?

Future value is the plain dollar figure your investments grow to over time. Today's value after inflation is what that future sum will actually buy in today's money. It shows your real buying power once you factor in rising prices.

How does inflation affect long-term investments?

Inflation eats away at what your money can buy. Over 30 years, steady 3% inflation cuts buying power by nearly 60%. So $1,000,000 in the future would buy only about what $412,000 buys today.

What is the future value formula?

Future value of a lump sum is FV = PV × (1 + r)^n, where PV is what you invest today, r is the annual return as a decimal, and n is the number of years. To see what that future amount is actually worth, divide it by (1 + i)^n, where i is the inflation rate, giving the real, today's-money value: FV_real = PV × [(1 + r) / (1 + i)]^n. The ratio inside the brackets is the real growth factor; with an 8% return and 3% inflation it is far smaller than the headline 1.08, which is why long projections that ignore inflation look roughly twice as good as they really are. This calculator always computes both numbers side by side, so the figure you plan around is the one that reflects actual buying power, not just the bigger number on paper.

Future Value Calculator

See what your money will grow to, and what it will actually buy in the future once you account for inflation.

Quick answer: In today's money, $50,000 invested now is worth about $207,284 in 30 years, once 3% inflation in a typical global scenario is taken into account. The pre-inflation figure is $503,133 (at an 8% annual return), but $207,284 is what it will actually buy, about 59% less. Change the amount, return, and horizon below. See methodology →

How We Work It Out

The future value is worked out in two steps:

1. Future Value (FV_nominal):

FV_nominal = PV × (1 + r)ⁿ

2. Today's Value After Inflation (FV_real):

FV_real = FV_nominal / (1 + i)ⁿ = PV × [(1 + r) / (1 + i)]ⁿ

Where: PV = present value (the amount you start with), r = annual return rate, i = annual inflation rate, and n = number of years.

Real-World Examples

What a $50,000 investment is really worth

Invest $50,000 at a 8% annual return for 30 years and it grows to $503,133. But at 3% inflation, that money will buy only about what $207,284 buys today, a 58.8% drop in buying power.
