You're 25 years old with $50,000 already saved. You plan to retire at 62, contribute $100 per month, and expect a 4% annual return. Your goal is to have $100,000 in annual retirement income. Based on these numbers, our calculator estimates you'll accumulate $311,447.19 by retirement age.
Applying the widely-used 4% withdrawal rule, that nest egg would generate only about $12,457.89 per year in sustainable income—leaving a massive annual shortfall of $87,542.11. Clearly, your current plan is not on track to meet your retirement income goal.

With a starting balance of $50,000, monthly contributions of $100, and a 4% annual return over 37 years, your total retirement savings reach $311,447.19. While that may sound like a decent sum, the sustainable withdrawal amount—commonly calculated as 4% of the portfolio—is just $12,457.89 per year. That's only about 12.5% of your desired $100,000 annual income.
The income gap is $87,542.11. This means you would need to find additional sources of income or drastically cut spending in retirement. The calculator indicates you are not on track. To close this gap, you must either significantly increase your monthly contributions, achieve a higher rate of return, delay retirement, or lower your target income.

If you increased your monthly contribution from $100 to $500, holding everything else constant, your retirement savings would jump to approximately $1,065,000. The 4% withdrawal would then provide $42,600 per year—still far short of $100,000, but a meaningful improvement. Alternatively, if you delay retirement to age 67 (45 years of contributions), your savings grow to about $581,000, sustainable income $23,240, but you'd still face a large gap.
Another option is to target a lower desired income. If you aim for $50,000 per year, your current plan would need about $1.25 million. That would require roughly $1,200 per month in contributions. The comparison shows that realistic planning must balance contributions, returns, and income goals. Even small changes in contributions or returns compound immensely over 37 years.
The 4% rule is a historical guideline based on a 50/50 stock-bond portfolio over a 30-year retirement. It suggests you can withdraw 4% of your portfolio in the first year and adjust for inflation thereafter. However, future returns may differ, and for longer retirements (e.g., 37 years at age 62), a more conservative rate of 3-3.5% may be appropriate. Use it as a starting point, not a guarantee.
Small increases today have huge impacts over 37 years. For example, raising your monthly contribution from $100 to $300 could grow your savings to over $900,000, yielding about $36,000 in annual income. To get closer to $100,000, you'd need about $2.5 million, which requires around $2,000 per month at 4% return. The earlier you increase contributions, the less you need to save later.
This version of the calculator does not automatically adjust for inflation. The $100,000 desired income and $12,458 sustainable income are in today's dollars. Due to inflation over 37 years, your purchasing power will be eroded. A realistic plan should aim for a portfolio that grows faster than inflation, and consider adjusting your income target upward to maintain lifestyle.
Absolutely. Social Security could provide a significant portion of your retirement income. For someone born in 1999, full retirement age is 67, and benefits depend on your earnings history. At age 62, your benefit would be reduced. If you expect, say, $2,000 per month from Social Security ($24,000 annually), that would cut your income gap from $87,542 to $63,542. Include any pensions or rental income as well.
