Couple's Retirement Planner
Plan your financial future together with our Couple's Retirement Planner. This tool helps you estimate if your combined savings and investment strategy are on track to meet your desired retirement income goals, considering both your and your spouse's retirement timelines.
Understanding Your Couple's Retirement Plan
Retirement planning for couples involves unique considerations. Unlike individual planning, you need to account for two different timelines, potentially different life expectancies, and a shared financial goal. This calculator helps you visualize your combined financial trajectory towards a comfortable retirement.
Key Inputs Explained:
- Current Age & Desired Retirement Age: These determine the number of years you both have left to save. The calculator focuses on the first person to retire as the initial target for your desired income.
- Combined Current Retirement Savings: This is the total amount you and your spouse have already accumulated in retirement accounts (401ks, IRAs, etc.) and other investment vehicles intended for retirement.
- Combined Annual Retirement Savings: The total amount you both plan to contribute to your retirement savings each year. Consistency here is key.
- Expected Annual Investment Return (Pre-Retirement): The average annual growth rate you anticipate on your investments before you retire. This is crucial for compounding.
- Expected Annual Investment Return (Post-Retirement): The average annual growth rate you anticipate on your investments once you are retired. This helps your nest egg last longer.
- Desired Annual Retirement Income (Today's Dollars): The amount of income you believe you'll need each year in retirement, expressed in today's purchasing power. The calculator will adjust this for inflation.
- Expected Annual Inflation Rate: The rate at which the cost of living is expected to increase. This is vital for understanding the true purchasing power of your future income.
How the Calculation Works:
The calculator first determines the number of years until the first spouse retires. It then projects your combined current savings and future annual savings forward to that point, using your pre-retirement investment return. Simultaneously, it inflates your desired annual retirement income to reflect its purchasing power at the time of the first retirement.
To estimate the "Required Nest Egg," it uses a common guideline: the 4% rule. This rule suggests that you can safely withdraw 4% of your initial retirement portfolio each year, adjusted for inflation, without running out of money over a typical 30-year retirement. Therefore, your required nest egg is estimated as 25 times your inflation-adjusted desired annual income.
Finally, it compares your projected savings to the required nest egg to show you if you have a surplus or a shortfall, and what annual/monthly income your projected savings could realistically generate based on the 4% rule.
Example Scenario:
Let's say you are 40, your spouse is 42. You plan to retire at 65, your spouse at 67. You have $250,000 saved and contribute $20,000 annually. You expect a 7% pre-retirement return, 5% post-retirement, and desire $80,000/year in today's dollars with 3% inflation.
- Your Retirement Age: 65 (25 years from now)
- Spouse's Retirement Age: 67 (25 years from now for you, 23 years for spouse)
- Years Until First Retirement: 25 years (when you turn 65)
- Projected Combined Savings at First Retirement: Approximately $2,000,000
- Inflation-Adjusted Desired Annual Income: $80,000 * (1 + 0.03)^25 ≈ $167,000
- Required Nest Egg: $167,000 * 25 = $4,175,000
- Result: A significant shortfall. Your projected savings of $2,000,000 would only generate an annual income of $80,000 (4% of $2M), which is far less than the inflation-adjusted $167,000 needed.
This example highlights the importance of starting early, saving consistently, and understanding the impact of inflation on your future purchasing power. Adjusting your savings rate, retirement age, or desired income can significantly alter the outcome.
Important Considerations:
- This calculator provides an estimate and should not replace professional financial advice.
- It does not account for Social Security, pensions, or other income sources.
- Investment returns and inflation rates are estimates and can vary significantly.
- Taxes on withdrawals are not included in this calculation.
- Healthcare costs in retirement can be substantial and are not factored in.
Use this tool as a starting point for discussions with your spouse and a financial advisor to create a comprehensive retirement plan tailored to your specific situation.
