Formula Explained
The calculator uses the standard auto loan payment formula:
Monthly Payment Formula
M = P [i(1 + i)^n] / [(1 + i)^n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate / 12)
- n = Number of payments (loan term in months)
This formula accounts for the interest on the remaining balance each month, creating an amortizing loan.
Important Notes
Actual payments may vary slightly due to rounding and Navy Federal's specific loan terms. This calculator provides an estimate based on standard assumptions.
Worked Example
Let's calculate a $25,000 loan with a 4.5% annual interest rate over 60 months (5 years):
| Input | Value |
|---|---|
| Loan Amount | $25,000 |
| Interest Rate | 4.5% |
| Loan Term | 60 months |
Using the formula:
Calculation Steps
1. Monthly interest rate = 4.5% / 12 = 0.375% or 0.00375
2. Number of payments = 60
3. Monthly payment = $25,000 [0.00375(1 + 0.00375)^60] / [(1 + 0.00375)^60 - 1]
4. Result = $25,000 [0.00375 × 1.2456] / [1.2456 - 1] = $25,000 × 0.00375 × 1.2456 / 0.2456 ≈ $472.36
The estimated monthly payment would be $472.36, with a total interest of $3,744.00 over the loan term.
