What is 401(k) Borrowing?

Borrowing from your 401(k) plan means taking a loan from your own retirement savings. While it may provide quick access to funds, you are required to repay the loan with interest. The major trade-off is that the borrowed funds are no longer invested, so you miss out on potential compound growth. Moreover, if you fail to repay, the outstanding balance may be treated as a distribution, resulting in taxes and potential penalties.

Loan Repayment: You repay the borrowed amount with interest to your own account.
Lost Returns: The money taken out will not earn investment returns, potentially reducing your retirement savings.
Penalties and Taxes: If the loan is not repaid according to the plan’s terms, it could be treated as an early withdrawal, incurring income taxes and a 10% penalty (if under age 59½).

Cost Calculations

To understand the true cost of borrowing from your 401(k), you need to consider:

Lost Returns: The potential growth of the borrowed amount if it had remained invested. This can be estimated using the compound interest formula:
$$ \text{Lost Returns} = L \times \left[(1 + r)^n – 1\right] $$

Where:
- $L$ is the amount borrowed,
- $r$ is the expected annual rate of return, and
- $n$ is the number of years the money would have been invested.
Potential Penalties:
If you fail to repay the loan, it could be treated as an early distribution subject to a 10% penalty plus applicable income taxes.

Key Concepts

Opportunity Cost: The lost potential gain from investing the borrowed funds.
Compound Interest: The interest on an investment that is calculated on both the initial principal and the accumulated interest.
Repayment Terms: The schedule and conditions under which you must repay the 401(k) loan.
Penalties and Taxes: Additional costs incurred if the loan is not repaid on time.

Step-by-Step Process

Determine the Borrowed Amount ($L$):
Identify the amount you wish to borrow from your 401(k).
Estimate the Expected Rate of Return ($r$):
Choose an annual rate of return that you expect your investments to earn if left in your account.
Set the Investment Duration ($n$):
Determine the number of years the money would have been invested.
Calculate Lost Returns:
Use the formula to estimate the lost returns:

$$ \text{Lost Returns} = L \times \left[(1 + r)^n – 1\right] $$
Assess Potential Penalties:
Understand that if you do not repay the loan according to the plan, you may incur a 10% penalty plus income taxes on the outstanding balance.
Review the Total Cost:
Combine the estimated lost returns and potential penalties to get an overall picture of the true cost of borrowing from your 401(k).

Practical Examples

Example: Calculating the Cost of Borrowing \$10,000

Scenario: Suppose you borrow \$10,000 from your 401(k) and the expected annual return on your investments is 7%. If the money would have been invested for 10 years, calculate the lost returns.

Variables:
$ L = \$10,000 $, $ r = 0.07 $, $ n = 10 $ years.
Calculate Lost Returns:
$$ \text{Lost Returns} = 10000 \times \left[(1 + 0.07)^{10} – 1\right] $$
Result:
If $ (1+0.07)^{10} \approx 1.967 $, then lost returns ≈ $ 10000 \times (1.967 – 1) = 10000 \times 0.967 = \$9,670 $.
Consider Penalties:
If you default on repayment, you could face a 10% penalty plus taxes on \$10,000.
Interpretation:
Borrowing \$10,000 could potentially cost you approximately \$9,670 in lost investment returns over 10 years, in addition to any penalties and taxes if repayment terms are not met.
