Managing your finances during retirement planning or career transitions can be challenging, especially when considering a 401(k) loan. Borrowing from your retirement account can provide a short-term solution for large expenses, but it requires careful planning to avoid penalties, interest, and reduced retirement savings.
Our 401(k) Loan Calculator is designed to help you estimate both monthly payments and total repayment costs before taking out a loan from your retirement account. This allows for informed decisions and better financial planning.

Loan Repayment Details
What Is a 401(k) Loan?
A 401(k) loan is a borrowing option offered by many employer-sponsored retirement plans. It allows you to borrow money from your own 401(k) account, which you repay with interest over a set period. Unlike other loans:
- You’re borrowing from yourself, so approval is easier.
- The interest paid goes back into your 401(k) account.
- Loan limits are usually capped at the lesser of $50,000 or 50% of your vested account balance.
While a 401(k) loan can provide flexibility, it carries risks, including potential taxes and penalties if the loan is not repaid on time or if you leave your employer.
How the 401(k) Loan Calculator Works
The calculator uses a standard loan amortization formula to compute:
- Monthly Payment – How much you’ll pay each month.
- Total Payment – The total amount you’ll repay over the life of the loan, including interest.
The formula accounts for:
- Loan principal (percentage of your 401(k) balance)
- Annual interest rate
- Loan term in years
This ensures that your monthly payments are accurate and realistic for your budget.
How To Use the 401(k) Loan Calculator
Step 1: Enter Your 401(k) Balance
Input the total amount currently in your 401(k) account.
Example:
- $100,000 balance
Step 2: Enter Loan Amount Percentage
Specify the percentage of your 401(k) you plan to borrow.
Example:
- Borrow 40% of your balance → $40,000
Step 3: Enter Loan Term
Choose the repayment duration in years.
Example:
- 5-year loan term
Step 4: Enter Interest Rate
Input the annual interest rate. This is typically determined by your plan administrator.
Example:
- 5% annual interest rate
Step 5: Click “Calculate”
The calculator will instantly display:
- Monthly Payment – How much you need to pay each month.
- Total Payment – The total cost of the loan over the term.
Step 6: Reset (Optional)
Use the reset button to start fresh calculations with different inputs.
Example Calculation
Let’s consider a scenario:
- 401(k) Balance: $80,000
- Loan Percentage: 50%
- Loan Term: 5 years
- Interest Rate: 4%
Calculation:
- Principal = $80,000 × 50% = $40,000
- Monthly Interest Rate = 4% ÷ 12 = 0.00333
- Months = 5 × 12 = 60
Using the amortization formula:MonthlyPayment=1−(1+MonthlyRate)−MonthsPrincipal×MonthlyRate
Result:
- Monthly Payment: $736.07
- Total Payment: $44,164.20
This example demonstrates how small interest rates over several years can add up, emphasizing the need for careful planning.
