The Retirement Savings Calculator projects the potential value of your retirement portfolio by factoring in your current savings, contributions, investment returns, and inflation. It provides a roadmap to understand if you are on pace to meet your financial goals in retirement by estimating your future nest egg.
This tool is ideal for anyone actively planning for retirement, from young professionals starting their first 401(k) to those nearing retirement age assessing their readiness. It's particularly useful for individuals who want to estimate their future retirement nest egg, adjust their savings strategy to meet specific income goals, or understand the impact of different investment returns and inflation.
Interpreting Results
Start with Years To Retirement. Then compare Projected Nest Egg and Target Nest Egg before deciding what changes the answer most.
Input Steps
Field by field
- 1
Current Age + Retirement Age
Enter current age, retirement age, current savings, annual contributions, expected return, inflation, desired retirement spending, and Social Security or pension income using today's dollars. Include employer match only if it is likely to continue.
- 2
Current Savings + Annual Contribution
Read projected nest egg versus target nest egg and focus on the contribution gap. The target is usually driven by the spending gap you need the portfolio to cover, divided by the withdrawal rate.
- 3
Annual Return Percent + Annual Inflation Percent
If the projected nest egg is more than about 15% below target, you probably need a higher savings rate, lower planned spending, or a later retirement age. A 70%-80% income-replacement shortcut is less reliable than using real spending.
- 4
Desired Annual Spending + Social Security Annual
Raise contributions by 1%-2% of salary, delay retirement by a year, or lower planned spending and compare which lever moves the gap fastest. Then use the Roth vs Traditional IRA calculator or 401k match optimizer to direct new contributions efficiently.
- 5
Withdrawal Rate Percent
Re-run annually and after salary, market, or Social Security estimate changes. Track projected gap, retirement age, and expected withdrawal rate together.
- 6
