Financial calculators · United States
The number after inflation is the only one you get to spend.
Most calculators stop at the nominal figure. Every tool here shows the inflation-adjusted result alongside it, states its assumptions in full, and models the fees that quietly eat the difference.

CalculatorWhy we show two numbers
Say you project a portfolio to $1.2 million in thirty years. At 2.5% inflation that pile buys what about $572,000 buys today. Both numbers are true. Only one of them tells you whether you can retire.
The habit of quoting nominal figures is not dishonest, but it is convenient — large numbers are persuasive, and the inflation adjustment is the step most tools skip. We put the real figure in the same visual weight as the nominal one, on every calculator, by default.
What we will not do
No email gate, no "get your personalised plan" funnel, no lead form selling your details to an advisory firm. The calculators are complete on the page. Each one publishes its formula and lists what it does not model, so you can judge whether the output applies to you.
