How Much Do You Need to Retire?

A common rule of thumb is the 4% rule: if you withdraw 4% of your portfolio per year, your savings should last roughly 30 years in retirement. So if you have $1,000,000 saved, you could withdraw about $40,000/year ($3,333/month) without depleting your nest egg too quickly.

This retirement calculator projects your savings growth based on your current age, savings, monthly contributions, and an expected annual return — then estimates your monthly retirement income using the 4% rule (or any withdrawal rate you choose).

🎯

The 4% Rule

A widely used guideline for how much you can safely withdraw each year in retirement without running out of money.

📈

Compounding Matters

Starting just 5–10 years earlier can dramatically increase your final retirement balance due to compound growth.

💰

Employer Match

If your employer matches 401(k) contributions, include that in your monthly contribution — it's essentially free money.

Frequently Asked Questions

A common guideline is to have 1× your annual salary saved by age 30, 3× by age 40, and 6× by age 50. These are rough benchmarks — your actual target depends on your desired retirement lifestyle, expected expenses, and other income sources like Social Security.
Many planners use 6–7% for a diversified stock portfolio (reflecting long-term inflation-adjusted S&P 500 returns), or 4–5% for a more conservative mix of stocks and bonds. The closer you are to retirement, the more conservative your assumption should typically be.
The 4% rule suggests withdrawing 4% of your portfolio in year one of retirement, then adjusting for inflation each year after. It's based on historical market data and is designed to make your savings last about 30 years. Some experts now suggest 3–3.5% for added safety given longer lifespans and lower bond yields.
No — this calculator only projects your personal savings and investment growth. Social Security, pensions, and other income sources would be additional income on top of the monthly amount estimated here.
Compounding means your returns generate their own returns over time. A 25-year-old who invests $300/month at 7% will end up with significantly more by retirement than a 35-year-old contributing the same amount — even though the older saver contributes for fewer years, the difference in growth time is substantial.
