Retirement Runway

Enter your savings, your monthly spending, and any other income, and we'll draw the balance down month by month to estimate how long it lasts — and the age it's projected to run out.

New here? See it work with example numbers:

What you have

The invested balance you'll draw from.

Used to show the age your balance is projected to run out.

Spending & income

What you expect to spend each month in retirement.

Social Security, a pension, part-time work — only the gap comes from savings.

Assumptions
%

On the invested balance in retirement. A planning assumption, not a guarantee.

%

How fast your spending rises each year.

What this tool does and doesn’t do

  • Does: draw your balance down month by month — growing it at your assumed return and your spending at inflation, net of any other income — until it runs out, and show the age it reaches zero plus a 4%-rule reference.
  • Doesn’t yet: taxes on withdrawals, sequence-of-returns risk (market crashes early in retirement), required minimum distributions, Social Security taxation or claiming strategy, annuities, long-term-care costs, or spending that changes across retirement.
  • This is a hypothetical projection under steady-return assumptions, not investment or retirement advice. Real markets are uneven — a run of poor early years can shorten the runway, so leave a margin.
