Screenshots show the built-in sample plan — your numbers will look different, but the layout is the same.

Cash Flow

A visual money-flow diagram for any year. The Sankey diagram shows where every dollar comes from and where it goes.

Three KPI cards (top row)

  • Money in (green): Total of all incomes + withdrawals. The sub-line names which simulated year you are viewing and the household age.
  • Spending + tax (red): Total expenses + federal tax + FICA. Sub: percentage of inflow saved.
  • Ending balance: Final account balance. Its sub-line reads "Depleted", "Surplus reinvested", or "Funded".

Year scrubber

Drag the slider — or use the arrow buttons and keyboard arrows — to travel through the simulation year by year. The person-age chips and year label update as you scrub, and the KPI cards plus the Sankey diagram below re-render for the selected year, so you can compare working years, early retirement, RMD years, and late retirement side by side.

Sankey money-flow diagram

Cash Flow Sankey diagram: income sources on the left pool into Money available, then split into spending and savings
Left column: income sources (taxable withdrawals dominate this year). Center: the Money available hub. Right: spending uses — essential in red, discretionary in coral. Ribbon width is proportional to dollars; hover any ribbon for exact amounts.

Withdrawals are shown pre-tax: the engine grosses them up so the tax bill is covered without double-counting.

How the columns work, left to right

  • Income sources: Wages (green), Social Security (violet), Pension (teal), Dividends (sky), Interest (orange), Pre-tax withdrawals (indigo), Roth/tax-free (blue), Cash on hand. A red "Depleted balance" node appears when expenses exceed inflows.
  • Money available (hub): The pooled inflow from all sources.
  • Uses: Essential spending (red), Discretionary (coral), One-time (orange), Interval (yellow), Federal tax (violet), FICA (indigo), Savings (green/teal), and "Stays in accounts" (unspent surplus).
  • Account buckets (right): Pre-tax 401(k)/IRA, Roth/HSA, Taxable & cash, Held as cash.
