What is a 401(k) Plan?

A 401(k) plan is a retirement savings account offered by many employers that allows employees to save a portion of their paycheck before taxes are taken out. The contributions are often matched by the employer up to a certain percentage, making it a valuable tool for retirement planning.

How to Use the 401(k) Contribution Calculator?

This calculator allows you to estimate how much your 401(k) savings will grow by the time you retire. You will need to input the following information:

  1. Current Age: Your current age in years.
  2. Desired Retirement Age: The age at which you plan to retire.
  3. Annual Income: Your total annual income before taxes.
  4. Contribution Rate: The percentage of your annual income that you plan to contribute to your 401(k).
  5. Expected Annual Return: The average annual return you expect from your investments in the 401(k).
  6. Current 401(k) Balance: The current amount of money you have saved in your 401(k).

Calculation Formula

The calculator uses the following formulas to estimate your future 401(k) balance:

  1. Total Contributions: §§ \text{Total Contributions} = \text{Annual Income} \times \text{Contribution Rate} \times \text{Years to Retirement} §§

  2. Future Value of 401(k): §§ \text{Future Value} = \text{Current Balance} \times (1 + \text{Expected Return})^{\text{Years to Retirement}} + \text{Total Contributions} \times \frac{(1 + \text{Expected Return})^{\text{Years to Retirement}} - 1}{\text{Expected Return}} §§

Where:

  • Total Contributions is the total amount you will contribute to your 401(k) over the years until retirement.
  • Future Value is the estimated total value of your 401(k) at retirement.

Example Calculation

Let’s say you are currently 30 years old and plan to retire at 65. Your annual income is $50,000, and you plan to contribute 10% of your income. You expect an annual return of 5% on your investments, and you currently have $10,000 in your 401(k).

  1. Current Age: 30
  2. Desired Retirement Age: 65
  3. Annual Income: $50,000
  4. Contribution Rate: 10%
  5. Expected Annual Return: 5%
  6. Current 401(k) Balance: $10,000

Calculations:

  • Years to Retirement: 65 - 30 = 35 years
  • Total Contributions: $50,000 × 0.10 × 35 = $175,000
  • Future Value:
    • Current Balance Growth: $10,000 × (1 + 0.05)^{35} = $50,000 (approximately)
    • Future Value: $50,000 + $175,000 × \frac{(1 + 0.05)^{35} - 1}{0.05} = $1,200,000 (approximately)
