Formula Used

The calculator uses the following formula to estimate your monthly auto costs:

Monthly Cost = (Annual Fuel Cost + Annual Insurance Cost + Annual Maintenance Cost + Annual Depreciation) / 12

Where:

Annual Fuel Cost = (Miles Driven / Miles per Gallon) × Fuel Price × 12
Annual Insurance Cost = Insurance Premium × 12
Annual Depreciation = (Purchase Price × Depreciation Rate) / 5

The calculator uses standard assumptions for fuel efficiency, depreciation rates, and insurance costs based on average values in the US.

Worked Example

Let's calculate the monthly cost for a $25,000 car with the following details:

Fuel type: Gasoline
Annual mileage: 15,000 miles
Insurance type: Comprehensive
Annual maintenance: $500

Using the calculator with these inputs, the estimated monthly cost would be approximately $425. This includes:

Fuel: $1,500/year
Insurance: $1,200/year
Maintenance: $500/year
Depreciation: $5,000/year

This example shows that the depreciation cost is the largest factor in the total monthly expense.
