How the projection works

This is a standard compound-growth projection: your current savings and every future monthly contribution are assumed to grow at your expected annual return until your retirement age. The projected balance is then multiplied by your chosen withdrawal rate to estimate a sustainable annual income.

Worked example

Suppose you're 30 years old, plan to retire at 65, have $20,000 saved, contribute $500 a month, and expect a 7% annual return:

  • Years to grow: 65 − 30 = 35 years
  • Projected balance at 65: roughly $1,135,903
  • Estimated sustainable income at a 4% withdrawal rate: roughly $45,436/year (about $3,786/month)

Try these exact numbers in the calculator above to see the full year-by-year growth path.

Frequently asked questions

What is the 4% withdrawal rate?+

It's a commonly cited starting point (sometimes called the '4% rule') for how much you might withdraw from a retirement portfolio each year without a high risk of running out of money over a multi-decade retirement. It's a rough historical guideline, not a guarantee — actual safe withdrawal rates depend on market conditions, your portfolio mix, how long your retirement lasts, and other income sources.

Does this include Social Security, a pension, or other income?+

No — this projects only the savings you enter and the income a withdrawal rate would generate from that balance. Any other retirement income (Social Security, a pension, rental income, etc.) would be on top of what's shown here.

Does it account for inflation?+

No — the projected balance and income are in nominal (today's) dollars terms based on your entered growth rate, not adjusted for inflation eroding purchasing power over a long horizon. Use the Inflation Calculator alongside this one to see how much a future dollar amount is really worth in today's terms.

What return rate should I use?+

This varies a lot by portfolio mix (stocks vs. bonds vs. cash) and time horizon. Many long-term retirement projections use a conservative long-run historical average, but returns vary significantly year to year and are never guaranteed — try a few different rates to see how sensitive your projection is.
