Important Loan Components Explained

This is the actual amount borrowed after subtracting your down payment.
2. Interest Rate
This is the cost of borrowing money, charged annually by the lender.
3. Loan Term

4. Down Payment
Initial payment that reduces your loan burden and monthly installments.
Example Calculation
Let’s understand how the calculator works with a real example.
Scenario:
- Car Price (Loan Amount): $30,000
- Down Payment: $5,000
- Interest Rate: 6% annually
- Loan Term: 144 months
Step 1: Calculate Loan Amount
Loan Amount = 30,000 − 5,000 = 25,000
Step 2: Results Summary
| Description | Value |
|---|---|
| Loan Amount | $25,000 |
| Monthly Payment | $245.60 |
| Total Payment | $35,366.40 |
| Total Interest | $10,366.40 |
Step 3: Interpretation
- You pay around $245 per month
- Total cost of car becomes $35,366.40
- Interest paid over 12 years is $10,366.40
This shows how long-term loans significantly increase total cost due to interest.
