Understanding Your Results
Projected Nest Egg
This is the estimated total amount you'll have saved by your retirement age. It includes your current savings, future contributions, and compound growth.
Monthly Retirement Income
Based on the 4% withdrawal rule, this is the estimated monthly income you can safely withdraw from your retirement savings without running out of money.
Years Until Retirement
The number of years you have to save and grow your retirement fund.
Total Contributions
The sum of all the money you'll personally contribute to your retirement savings from now until retirement.
The Formula Behind the Calculation
Future Value Formula:
FV = PV(1+r)^n + PMT × [((1+r)^n - 1) / r]
Where:
- FV = Future Value (nest egg at retirement)
- PV = Present Value (current savings)
- r = Monthly interest rate (annual return ÷ 12)
- n = Number of months until retirement
- PMT = Monthly contribution
4% Rule for Withdrawal:
- A widely-accepted guideline suggests withdrawing 4% of your portfolio in the first year of retirement
- This provides sustainable income for approximately 30 years
Source: The 4% rule was established by financial planner William Bengen in 1994, based on historical market data.
Retirement Planning Strategies
Start Early
The power of compound interest means that starting early can make a huge difference. Even small contributions in your 20s can grow significantly by retirement.
Maximize Employer Match
If your employer offers a 401(k) match, contribute at least enough to get the full match—it's essentially free money.
Diversify Investments
A mix of stocks, bonds, and other assets can help balance risk and return over your working years.
Increase Contributions Over Time
As your income grows, try to increase your retirement contributions proportionally.
Frequently Asked Questions
How much do I need to retire?
A common rule of thumb is to save 10-12 times your final salary. However, your needs depend on your lifestyle, health, and retirement goals.
What's a good retirement savings rate?
Financial advisors typically recommend saving 10-15% of your income for retirement, including any employer match.
What annual return should I expect?
Historically, a diversified portfolio has returned 6-8% annually after inflation. This calculator defaults to 7%, but you can adjust based on your investment strategy.
When can I retire?
You can access Social Security benefits as early as 62, but waiting until 67 (full retirement age) or 70 maximizes your benefits. 401(k) and IRA withdrawals are penalty-free at 59½.
What about Social Security?
This calculator focuses on personal savings. Social Security may provide additional income in retirement, but benefits vary based on your earnings history.
