Household

Retirement age & month is when wages / self-employment stop — the month is the number of months after the birthday (0 = the birthday month), shown with the calendar month it lands on. That year's wages count only through the month before. Pick Already retiredif they've stopped working already. The portfolio funds the gap between retiring and claiming Social Security (which can be later); other income (pensions, etc.) continues. State income tax is modeled for CA, NY & PA (and the no-income-tax states FL, TX, WA); other states assume $0 state tax.

Spending & goals

Essentials are must-haves; lifestyle is discretionary on top; legacy is a bequest you want to leave. The planner funds these as tiers and reports a funded ratio for each.

Social Security

Marcus: pays from age 67 through age 95.

Auto-filled from the claim age and your plan-through age — no need to enter Social Security as a dated income row.

Benefits pay $0 until the claim age, then a percentage of your PIA — 70% at 62, 100% at FRA (67), 124% at 70 — COLA-adjusted each year. Leave blank if SS doesn't apply. The planner can model which claim age produces the highest after-tax wealth in your projection.

Planning assumptions

A single deterministic return and inflation rate drive the planner's projection (no Monte Carlo). Longevity sets how many years the plan covers.
