The Honda Car Calculator helps you determine various financial aspects related to purchasing and owning a Honda car. This includes calculating monthly loan payments, annual fuel costs, and the total cost of ownership. By using this calculator, you can make more informed decisions about your car purchase and better manage your budget.

## Purpose and Functionality

The Honda Car Calculator is designed to provide you with a comprehensive overview of the costs associated with buying and maintaining a Honda car. It takes into account several factors such as the car price, down payment, loan term, interest rate, annual mileage, fuel efficiency, fuel price, maintenance cost, and insurance cost. By inputting these details, you can get a clear picture of your monthly and yearly expenses related to the car.

## Inputs:

**Car Price**: The total price of the car (in dollars).**Down Payment**: The initial payment made when purchasing the car (in dollars).**Loan Term**: The duration of the loan (in years).**Interest Rate**: The annual interest rate on the loan (percentage).**Annual Mileage**: The estimated number of miles driven per year.**Fuel Efficiency**: The car’s fuel efficiency (miles per gallon).**Fuel Price**: The cost of fuel per gallon (in dollars).**Maintenance Cost**: The estimated annual maintenance cost (in dollars).**Insurance Cost**: The estimated annual insurance cost (in dollars).

## Formulas and Calculations:

## Monthly Loan Payment:

The formula to calculate the monthly loan payment is:

[ \text{Monthly Payment} = \frac{\text{Loan Amount} \times \left( \frac{\text{Interest Rate}}{12} \right)}{1 – \left(1 + \frac{\text{Interest Rate}}{12}\right)^{-\text{Loan Term} \times 12}} ]

Where:

**Loan Amount**= Car Price – Down Payment**Interest Rate**is in decimal form (e.g., 5% = 0.05).

## Annual Fuel Cost:

The formula to calculate the annual fuel cost is:

[ \text{Annual Fuel Cost} = \frac{\text{Annual Mileage}}{\text{Fuel Efficiency}} \times \text{Fuel Price} ]

## Total Cost of Ownership:

The formula to calculate the total cost of ownership per year is:

[ \text{Total Cost of Ownership} = \text{Annual Fuel Cost} + \text{Maintenance Cost} + \text{Insurance Cost} + \left(\text{Monthly Payment} \times 12\right) ]

## Example Calculation:

**Inputs**:

- Car Price: $30,000
- Down Payment: $5,000
- Loan Term: 5 years
- Interest Rate: 5%
- Annual Mileage: 12,000 miles
- Fuel Efficiency: 30 miles per gallon
- Fuel Price: $3 per gallon
- Maintenance Cost: $500
- Insurance Cost: $1,200

## Step-by-Step Calculation:

**Monthly Loan Payment**:

- Loan Amount = $30,000 – $5,000 = $25,000
- Interest Rate = 5% = 0.05
- Using the formula:

[\text{Monthly Payment} = \frac{25000 \times \left( \frac{0.05}{12} \right)}{1 – \left(1 + \frac{0.05}{12}\right)^{-5 \times 12}}] - Calculating the Monthly Payment:

[\text{Monthly Payment} = \frac{25000 \times 0.004167}{1 – \left(1 + 0.004167\right)^{-60}}]

[\text{Monthly Payment} \approx \frac{104.175}{1 – 0.779}]

[\text{Monthly Payment} \approx \frac{104.175}{0.221}]

[\text{Monthly Payment} \approx 471.85]

**Annual Fuel Cost**:

- Using the formula:

[\text{Annual Fuel Cost} = \frac{12000}{30} \times 3 = 400 \times 3 = 1200]

**Total Cost of Ownership**:

- Using the formula:

[\text{Total Cost of Ownership} = 1200 + 500 + 1200 + (471.85 \times 12)]

[\text{Total Cost of Ownership} = 1200 + 500 + 1200 + 5662.20]

[\text{Total Cost of Ownership} = 8562.20]

### CONCLUSTION

The calculated monthly loan payment for the car is approximately $471.85. The annual fuel cost is $1,200, and the total cost of ownership per year, including fuel, maintenance, insurance, and loan payments, is $8,562.20.
