Calculation Examples

New Car Purchase

Input Values

Car Price: 30,000$
Down Payment: 5,000$
Interest Rate: 5.5%
Loan Term: 5years
Trade-in Value: 0$
Payment Type: annuity
Sales Tax: 0%
Registration Fees: 0$
Extended Warranty: 0$
Gap Insurance: 0$

Calculation Steps

  1. Car price: $30,000
  2. Down payment: $5,000
  3. Trade-in value: $0
  4. Loan amount: $30,000 - $5,000 = $25,000
  5. Interest rate: 5.5% APR
  6. Loan term: 5 years
  7. Monthly interest rate: 5.5% ÷ 12 = 0.4583% = 0.004583
  8. Number of payments: 5 years × 12 months = 60 payments
  9. Monthly payment formula: M = P × [r(1+r)^n] / [(1+r)^n - 1]
  10. Where P = $25,000, r = 0.004583, n = 60
  11. (1+r)^n = (1.004583)^60 = 1.3156
  12. M = $25,000 × [0.004583 × 1.3156] / [1.3156 - 1]
  13. M = $25,000 × 0.006028 / 0.3156 = $477.42
  14. Monthly payment: $477.42
  15. Total payment: $477.42 × 60 = $28,645.20
  16. Total interest: $28,645.20 - $25,000 = $3,645.20

Calculated Results

Calculation not available. Showing fallback result below.

Expected Result

This example shows a typical new car purchase. The monthly payment of $477.42 fits within most budgets, and the total interest of $3,645.20 represents the cost of financing over 5 years. Consider making a larger down payment or choosing a shorter term to reduce total interest.

With Trade-In

Input Values

Car Price: 35,000$
Down Payment: 3,000$
Interest Rate: 4.9%
Loan Term: 6years
Trade-in Value: 8,000$
Payment Type: annuity
Sales Tax: 0%
Registration Fees: 0$
Extended Warranty: 0$
Gap Insurance: 0$

Calculation Steps

  1. Car price: $35,000
  2. Down payment: $3,000
  3. Trade-in value: $8,000
  4. Loan amount: $35,000 - $3,000 - $8,000 = $24,000
  5. Interest rate: 4.9% APR
  6. Loan term: 6 years
  7. Monthly interest rate: 4.9% ÷ 12 = 0.4083% = 0.004083
  8. Number of payments: 6 years × 12 months = 72 payments
  9. Monthly payment formula: M = P × [r(1+r)^n] / [(1+r)^n - 1]
  10. (1+r)^n = (1.004083)^72 = 1.3408
  11. M = $24,000 × [0.004083 × 1.3408] / [1.3408 - 1]
  12. M = $24,000 × 0.005473 / 0.3408 = $384.15
  13. Monthly payment: $384.15
  14. Total payment: $384.15 × 72 = $27,658.80
  15. Total interest: $27,658.80 - $24,000 = $3,658.80
  16. Note: Trade-in reduces loan amount, lowering monthly payment and total interest

Calculated Results

Calculation not available. Showing fallback result below.

Expected Result

Using a trade-in significantly reduces your loan amount. In this example, the $8,000 trade-in brings the loan down to $24,000, resulting in a lower monthly payment of $384.15. This demonstrates how trading in your current vehicle can make a more expensive car more affordable.

Short Term Loan

Input Values

Car Price: 25,000$
Down Payment: 10,000$
Interest Rate: 3.9%
Loan Term: 3years
Trade-in Value: 0$
Payment Type: annuity
Sales Tax: 0%
Registration Fees: 0$
Extended Warranty: 0$
Gap Insurance: 0$

Calculation Steps

  1. Car price: $25,000
  2. Down payment: $10,000 (40%)
  3. Loan amount: $25,000 - $10,000 = $15,000
  4. Interest rate: 3.9% APR
  5. Loan term: 3 years
  6. Monthly interest rate: 3.9% ÷ 12 = 0.325% = 0.00325
  7. Number of payments: 3 years × 12 months = 36 payments
  8. Monthly payment formula: M = P × [r(1+r)^n] / [(1+r)^n - 1]
  9. (1+r)^n = (1.00325)^36 = 1.1237
  10. M = $15,000 × [0.00325 × 1.1237] / [1.1237 - 1]
  11. M = $15,000 × 0.003652 / 0.1237 = $441.23
  12. Monthly payment: $441.23
  13. Total payment: $441.23 × 36 = $15,884.28
  14. Total interest: $15,884.28 - $15,000 = $884.28
  15. Note: Shorter term (3 years) means higher monthly payment but much less total interest

Calculated Results

Calculation not available. Showing fallback result below.

Expected Result

A shorter loan term with a larger down payment results in significantly less interest paid. While the monthly payment is higher at $441.23, you'll only pay $884.28 in total interest compared to $3,645.20 in the 5-year example. This strategy saves money if you can afford the higher payment.

With Sales Tax and Fees

Input Values

Car Price: 28,000$
Down Payment: 5,000$
Interest Rate: 6%
Loan Term: 5years
Trade-in Value: 0$
Payment Type: annuity
Sales Tax: 7.5%
Registration Fees: 500$
Extended Warranty: 0$
Gap Insurance: 0$

Calculation Steps

  1. Car price: $28,000
  2. Down payment: $5,000
  3. Sales tax: 7.5% of $28,000 = $2,100
  4. Registration fees: $500
  5. Total vehicle cost: $28,000 + $2,100 + $500 = $30,600
  6. Loan amount: $30,600 - $5,000 = $25,600
  7. Interest rate: 6.0% APR, Loan term: 5 years
  8. Monthly interest rate: 6.0% ÷ 12 = 0.5% = 0.005
  9. Number of payments: 60
  10. Monthly payment: $494.75
  11. Total payment: $494.75 × 60 = $29,685.00
  12. Total interest: $29,685.00 - $25,600 = $4,085.00
  13. Note: Sales tax and fees increase the loan amount and total cost

Calculated Results

Calculation not available. Showing fallback result below.

Expected Result

Don't forget to include sales tax and registration fees in your calculations. In this example, the 7.5% sales tax ($2,100) and $500 registration fee increase the total financed amount to $25,600, raising both the monthly payment and total interest. Always factor in these costs when budgeting for a car purchase.
