Retirement Nest Egg Calculator

Your "nest egg" is the total savings needed to fund retirement. This calculator works backward from your desired retirement income to determine the target portfolio size, accounting for inflation, Social Security, and investment returns.

About This Calculator

With 35 years until retirement, starting from $100,000 in savings and contributing $500 per month at an assumed 7% annual return, you could accumulate approximately $1.9M by age 65.

This projection uses monthly compounding and assumes consistent contributions. In reality, your returns will vary year to year, but the long-term trend of disciplined saving combined with market growth has historically rewarded patient investors.

Use the full Retirement Calculator to run your own personalized scenarios with different contribution levels, return assumptions, and withdrawal plans.

Frequently Asked Questions

How much should a 30-year-old have saved for retirement?

+
Financial advisors commonly suggest having 1x your annual salary saved by age 30. However, the right number depends on your lifestyle goals, expected Social Security benefits, and retirement timeline. The important thing is to start — even small amounts compound significantly over 35 years.

Is 35 years enough time to build a retirement fund?

+
Yes — 35 years is a substantial runway for compound growth. Even modest monthly contributions can grow into a significant nest egg over this period.

What rate of return should I assume for retirement planning?

+
A common assumption is 6-7% for a diversified stock portfolio (after inflation, historically the S&P 500 has returned about 7% real). More conservative planners use 5-6%. The key is to be realistic — overly optimistic assumptions can lead to undersaving. Our calculator lets you test different rates.

Should I prioritize paying off debt or saving for retirement?

+
It depends on the interest rate. If your debt exceeds 6-7% interest (like credit cards), paying it off first typically makes sense since that guaranteed "return" beats expected market returns. For lower-rate debt (like mortgages at 3-4%), contributing to retirement simultaneously is often the better mathematical choice — especially if your employer offers a 401(k) match.
