The foundation of every retirement plan is a target number and an honest read on whether you'll reach it. These guides cover how to size that number, how inflation quietly moves it, and how to pressure-test your progress.
"How much do I need to retire?" is the question everyone starts with, and the honest answer is that it depends on what you'll spend, how long you'll live, and what the market does along the way. The guides below work through each piece: a fast way to get a first number, why inflation means that number keeps moving, and how to test it against the futures you can't predict. When you're ready to put real figures in, the calculator runs the whole thing as a Monte Carlo simulation.
Enter your savings, spending, and timeline, then run a Monte Carlo simulation to see how likely your plan is to last.
