Model how your cash reserves and retirement savings could work together, year by year, for the rest of your life, including inflation, income, big future expenses, and different growth assumptions before and after you retire.
This is the most advanced tool on the site. It works best once you've already tried the quick snapshot and expense planning steps.
A real retirement isn't one number, it's decades of moving parts: how markets perform and in what order, how long you and your spouse live, how fast health care and everyday costs rise, and how your spending needs change over time. Two households with the same starting balance can end up in very different places depending on the order returns happen in, not just their average. Professional planners often run hundreds or thousands of scenarios (an approach called Monte Carlo simulation) specifically because a single straight-line projection can hide that uncertainty.
The table below is a single deterministic projection, one path through all of these assumptions, not a range of possible outcomes. It's meant to make the mechanics visible and give you a working starting point, not to replace the kind of deeper, probability-based analysis a financial planner can walk you through.

Answer these once, then calculate your outlook. You can come back and adjust anything.
Until you retire, we simply grow your cash and retirement balances. These questions only come into play for the years after you retire.
A few moments worth noting from your projection.
