Understanding the Results
Financed Amount
The financed amount is the actual loan balance after subtracting the down payment.
Formula
Financed Amount = Vehicle Price − Down Payment
Example:
| Item | Amount |
|---|---|
| Vehicle Price | $40,000 |
| Down Payment | $5,000 |
| Financed Amount | $35,000 |
Monthly Payment
The monthly payment is the amount due each month throughout the loan term.
It includes:
- Principal repayment
- Interest charges
This is often the most important figure when budgeting for a vehicle purchase.
Total Interest
Total interest represents the extra money paid to the lender beyond the amount borrowed.
Higher interest rates and longer loan terms increase total interest costs.
Total Payment
Total payment equals the sum of all monthly payments over the life of the loan.
Formula
Total Payment = Monthly Payment × Number of Months
Loan Duration
Loan duration is displayed in months.
Example:
- 5 years = 60 months
- 6 years = 72 months
- 7 years = 84 months
Car Loan Payment Formula
The calculator uses the standard amortized loan formula.
M=P×(1+r)n−1r(1+r)n
Where:
| Variable | Meaning |
|---|---|
| M | Monthly Payment |
| P | Loan Principal |
| r | Monthly Interest Rate |
| n | Number of Monthly Payments |
Monthly Interest Rate Formula
r=12×100APR
Loan Duration Formula
n=Years×12
These formulas help determine the exact payment required to repay the loan in full by the end of the term.
Example Calculation
Let’s assume:
| Input | Value |
|---|---|
| Vehicle Price | $40,000 |
| Down Payment | $5,000 |
| Interest Rate | 6% |
| Loan Term | 5 Years |
Step 1: Calculate Financed Amount
$40,000 − $5,000 = $35,000
Step 2: Loan Details
| Detail | Value |
|---|---|
| Financed Amount | $35,000 |
| Monthly Rate | 0.5% |
| Loan Duration | 60 Months |
Estimated Results
| Result | Amount |
|---|---|
| Monthly Payment | $676.65 |
| Total Interest | $5,599 |
| Total Payment | $40,599 |
This example demonstrates how financing costs add thousands of dollars to the original vehicle price.

Impact of Down Payments
A larger down payment reduces:
- Loan balance
- Monthly payments
- Total interest paid
Example Comparison
| Down Payment | Loan Amount |
|---|---|
| $0 | $40,000 |
| $5,000 | $35,000 |
| $10,000 | $30,000 |
| $15,000 | $25,000 |
Even a modest down payment can save thousands of dollars over the life of the loan.
How Loan Terms Affect Payments
Longer terms reduce monthly payments but increase total interest.
Example: $40,000 Loan at 6%
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 36 Months | $1,217 | $3,812 |
| 48 Months | $939 | $5,072 |
| 60 Months | $773 | $6,396 |
| 72 Months | $663 | $7,736 |
| 84 Months | $584 | $9,056 |
While longer loans may seem more affordable each month, they often cost significantly more overall.
