Estimate the future value of your deferred compensation contributions.
Understanding Deferred Compensation
Deferred compensation is an arrangement where a portion of an employee's income is paid out at a later date, typically upon retirement or separation from the company. This strategy can offer tax advantages, allowing your earnings to grow tax-deferred until you receive them. It's a powerful tool for long-term financial planning, especially for high-income earners looking to supplement their retirement savings beyond standard employer-sponsored plans like 401(k)s.
This calculator helps you project the potential future value of your deferred compensation contributions. By inputting your annual contribution amount, the number of years you plan to contribute, your current and target retirement ages, and an assumed annual growth rate, you can gain an estimate of your potential deferred compensation nest egg.
How the Calculation Works
The calculation uses the future value of an ordinary annuity formula, modified to account for the total duration until withdrawal.
First, we determine the total number of years the contributions will be made. Let:
C = Annual Contribution Amount
N = Number of Years Contributing
The future value of these contributions at the point of the last contribution (i.e., at the end of the contribution period) is calculated using the future value of an ordinary annuity formula:
FV_annuity = C * [((1 + r)^N - 1) / r]
Where:
r = Annual Growth Rate (as a decimal)
However, the deferred compensation funds often continue to grow after contributions cease until retirement. We need to account for this additional growth period. Let:
CurrentAge = Your Current Age
RetirementAge = Your Target Retirement Age
The number of years the balance will continue to grow after contributions stop is:
GrowthYearsAfterContributions = RetirementAge - CurrentAge - N
If GrowthYearsAfterContributions is negative or zero, it means retirement age is reached at or before the last contribution, so no additional growth period is applied.
The total future value (FV) at retirement age is then:
Note: If GrowthYearsAfterContributions is negative, it's treated as 0.
Key Inputs Explained
Annual Contribution Amount: The total amount you expect to contribute from your compensation each year.
Number of Years Contributing: The duration over which you will make these contributions.
Current Age: Your age right now.
Target Retirement Age: The age at which you plan to start withdrawing the funds.
Assumed Annual Growth Rate: The average annual rate of return you expect your investments to generate. This is a crucial assumption and actual returns may vary.
Use Cases and Benefits
Retirement Supplement: Provides an additional source of retirement income.
Tax Deferral: Income and growth are not taxed until distribution.
Income Smoothing: Can help manage taxable income during peak earning years.
Financial Planning: Enables visualization of long-term wealth accumulation.
