The retirement calculator estimates how much you need to save, how much your current savings will grow by retirement, and whether you are on track to fund your retirement. It uses your savings rate, expected return, and retirement timeline.
How Much Do You Need to Retire?
The most widely used rule is the 25x rule: multiply your expected annual retirement spending by 25. If you plan to spend $60,000 per year, you need roughly $1,500,000. This is based on the 4% safe withdrawal rate, which research suggests can sustain a 30-year retirement. Higher spending or longer retirement may require a larger nest egg.
Retirement Nest Egg = Annual Spending x 25 Safe Annual Withdrawal = Portfolio Value x 4%
Example: $1,200,000 portfolio x 4% = $48,000/year. To spend $70,000/year: $70,000 x 25 = $1,750,000 needed.
Savings Needed at Each Age to Retire at 65
| Current Age | Annual Savings Needed | Assumes 7% Return, $1M Goal |
|---|---|---|
| 25 | $3,500/year | $292/month |
| 30 | $5,000/year | $417/month |
| 35 | $7,200/year | $600/month |
| 40 | $10,800/year | $900/month |
| 45 | $17,100/year | $1,425/month |
| 50 | $30,200/year | $2,517/month |
The Power of Starting Early
Investing $500/month from age 25 to 65 at 7% average annual return grows to approximately $1,320,000. Starting at 35 instead, the same $500/month grows to only $609,000. The 10-year head start nearly triples the outcome. The extra $60,000 contributed makes far less difference than the extra 10 years of compound growth.
Social Security and Other Income Sources
Social Security replaces about 40% of pre-retirement income for average earners, less for high earners. Pension income, rental income, and part-time work in early retirement also reduce how much your portfolio needs to provide. Subtract these income sources from your spending target before applying the 4% rule.
Frequently Asked Questions
How much money do I need to retire?⌄
Multiply your expected annual spending in retirement by 25. This is based on the 4% safe withdrawal rate. To spend $50,000/year, you need $1,250,000. To spend $80,000/year, you need $2,000,000. Factor in Social Security income to reduce how much your portfolio needs to cover.
What is the 4% rule for retirement?⌄
The 4% rule says you can withdraw 4% of your retirement portfolio in the first year, then adjust for inflation annually, and the money should last 30 years. It is based on historical stock and bond market returns. In lower-return environments or for retirements exceeding 30 years, some advisors recommend a 3-3.5% withdrawal rate.
How much should I save for retirement each month?⌄
A common benchmark is 15% of gross income, including employer match. If you start at 25, 10-12% may be sufficient. If starting at 40, 20-25% or more may be needed to catch up. Use this calculator with your current savings and expected return to get your specific target.
What is a good return to assume for retirement planning?⌄
A 6-7% real return (after inflation) is a common conservative assumption for a diversified stock and bond portfolio. The historical US stock market has returned about 10% annually before inflation and 7% after inflation. More conservative allocations with more bonds produce lower expected returns.
At what age should I start saving for retirement?⌄
As early as possible. The first dollar invested at 25 has roughly 4x the compounding time of a dollar invested at 45. If your employer offers a 401(k) match, contribute at least enough to get the full match immediately, regardless of age — that is a guaranteed 50-100% return on the first dollars contributed.
