What is TTL in Auto Loans?
TTL stands for Total Term Loan, which refers to a type of auto loan where the repayment period is fixed from the beginning. Unlike balloon loans, TTL loans have consistent monthly payments throughout the loan term, making them predictable and easier to budget for.
Key Features of TTL Loans
- Fixed repayment term
- Consistent monthly payments
- Predictable interest calculations
- No balloon payments at the end
TTL loans are popular among borrowers who prefer straightforward repayment schedules. The calculator below helps you estimate your monthly payments and understand the financial impact of your loan terms.
How to Use This Calculator
Using the auto loan calculator with TTL is simple. Follow these steps:
- Enter the loan amount you're considering
- Select the loan term in years
- Input the annual interest rate
- Click "Calculate" to see your results
Formula Used
The monthly payment for a TTL loan is calculated using the standard loan 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 divided by 12)
- n = Number of payments (loan term in years × 12)
Worked Example
Let's calculate a TTL loan with these parameters:
- Loan amount: $25,000
- Loan term: 5 years
- Annual interest rate: 4.5%
Using the formula:
- Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
- Calculate number of payments: 5 × 12 = 60
- Plug values into formula: M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 - 1 ]
- Calculate monthly payment: $452.34
Total interest paid over 5 years: $3,682.40
| Payment | Principal | Interest | Balance |
|---|---|---|---|
| 1 | $387.00 | $65.34 | $24,613.00 |
| 2 | $390.76 | $61.58 | $24,222.24 |
| 3 | $394.53 | $57.81 | $23,827.71 |
| 4 | $398.32 | $53.99 | $23,429.39 |
