Financial Plan

A whole household on one page: pay, taxes, spending, debts, goals and Social Security, projected year by year and run through 1,000 different markets. The question it answers is the one a planner asks first: will the money last?

 All results in today’s dollars

The Household

Change anything; everything below updates.

Debts

Payments come out of savings until each is paid off.

Goals

One-off costs in today’s dollars: a home, a car, tuition.

Assumptions

Returns, volatility, inflation

Returns are nominal and drawn at random each year around these averages. Stocks and bonds are only slightly correlated. Cash earns a little less than the 3-month Treasury.

Net Worth, 1,000 Markets

Copper: the middle outcome. Shaded: the middle 80%. Dashed: the worst 10%. Everything in today’s dollars.

What If

The same plan with one thing changed.

What It Would Take

The two levers most people have.

Debts

Year by Year

With average returns every year, in today’s dollars. Retirement row highlighted.

A teaching model, not a financial plan: taxes are one flat rate, all investments are treated as one account, and returns are random draws, not forecasts. Real planning also covers account types, required withdrawals, health costs, insurance and estate questions. Not investment advice.
