Loan Repayment Summary
What Is a 401k Loan?
A 401k loan is a type of loan you can take from your own 401k retirement account. Unlike traditional loans, a 401k loan uses your own retirement savings as collateral. The advantages include:
- No credit check
- Competitive interest rates
- Quick access to funds
However, it’s essential to understand that borrowing from your 401k can impact your long-term retirement growth, so careful planning is necessary.
How the Fidelity 401k Loan Calculator Works
The calculator uses the standard loan amortization formula to compute your monthly payments:Monthly Payment=1−(1+r)−nP×r
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of months (loan term × 12)
It also calculates:
- Total Payment = Monthly Payment × Total Months
- Total Interest = Total Payment − Principal
This ensures you have a clear picture of how much you’ll pay over the life of your 401k loan.

Example Calculation
Suppose:
- Loan Amount = $15,000
- Annual Interest Rate = 6%
- Loan Term = 5 years
Monthly Rate = 6% ÷ 12 = 0.5%
Monthly Payment:15,000×0.005/(1−(1+0.005)−60)≈$290.95
- Total Payment = $290.95 × 60 ≈ $17,457
- Total Interest = $17,457 − $15,000 ≈ $2,457
This example shows how much you’ll repay in interest while budgeting for monthly payments.

- Borrow only what you need.
- Consider the impact on your retirement savings.
- Repay on schedule to avoid penalties and taxes.
- Use a conservative interest rate estimate.

Why Loan Amortization Matters
Amortization breaks down your loan into:
- Principal: The original borrowed amount
- Interest: The cost of borrowing
Early in the loan term, payments mostly cover interest. Over time, more of your payment goes toward principal. Knowing this helps you plan your finances accurately.
