Retirement Calculator

Find out how much you need to retire comfortably, how much you'll have at retirement age, and whether you're on track.

To retire comfortably spending $60,000/year, you need $1.5 million (25× annual spending, 4% rule). A 35-year-old with $80,000 saved, investing $1,500/month at 7% real return, will have $2.4 million by age 65 — right on track.

How it's calculated

Retirement math: target, projection, and comparison

Target = Annual retirement spending ÷ SWR e.g. $60,000 ÷ 4% = $1,500,000 Projected at retirement = Current savings × (1+r)^years + Monthly × 12 × [(1+r)^years − 1] / r Annual income from portfolio = Projected × SWR

Safe Withdrawal Rate (SWR): The percentage of your portfolio you can withdraw annually without running out of money. 4% is the classic benchmark (Bengen, 1994) for 30-year retirements.
Real return: Return after inflation. Using real returns and real spending means you don't need to model inflation growth separately.
Nest egg: The total retirement portfolio needed to fund your retirement spending through the safe withdrawal rate.

🔢 Worked example

$60,000 in annual retirement spending ÷ a 4% withdrawal rate = a $1,500,000 target. Current savings of $200,000 plus $1,000/month at 7% for 25 years projects to about $1.84M — comfortably above target.

Frequently asked questions

How much do I need to retire?

The most common benchmark: 25× your annual retirement spending (4% SWR). If you plan to spend $60k/year: need $1.5M. For a longer early retirement, use 28–30× expenses (3.5% SWR). Include expected Social Security/pension income to reduce the target.

How much should I save for retirement each month?

Aim for 15–20% of gross income including employer match. Earlier starters can save less; starting later requires more. Even saving 10% consistently from age 25 builds significant wealth by 65 thanks to compounding.

What is a 401(k) and should I max it out?

A 401(k) is a US employer-sponsored tax-deferred retirement account. 2026 limit: $23,500 ($31,000 if 50+). Always contribute at least enough to get the full employer match first — that's a 50–100% instant return. Then max an IRA before adding more to 401(k).

What is Social Security and how does it affect my retirement?

Social Security is a US government retirement benefit funded by payroll taxes. In 2026, average monthly benefit ≈ $1,900. Your benefit amount depends on your earnings history and the age you start claiming (62–70). Include expected Social Security income to reduce the savings target in this calculator.

When can I retire?

When your portfolio can sustain your desired annual spending through the 4% rule. The age matters less than whether the math works. Many people target 60–65 for traditional retirement, but FIRE adherents aim for 40–55 with aggressive savings rates.

Are my results saved? Do I need an account?

No account or sign-up needed. Every calculation is saved automatically in your own browser, and you can also pin a result with the save button. Nothing is sent to any server: the data stays on your device and can be erased at any time with the clear button.

How do I track my progress over time?

From the fourth entry onward a “View comparison chart” button appears, opening a line chart with every entry in time order plus an indicator panel: total change, average per entry, lowest and highest value and the period covered. You can also export the history as CSV.

About this calculator

This retirement calculator projects the portfolio you will have when you stop working, starting from what you have already saved, your monthly contributions, and the real return you expect to earn, and then estimates the monthly income that portfolio can support.

Because the projection uses a real (inflation-adjusted) return, every figure is expressed in today’s purchasing power, so the numbers stay meaningful. The tool also shows income framed three ways — a perpetual withdrawal, the 4% rule, and drawing the balance down over 30 years — and flags whether your current plan reaches the target you set.
