1. Introduction

A Car Operating Cost Calculator helps vehicle owners estimate the total cost of owning and operating a car, including fuel, maintenance, insurance, depreciation, and other expenses. This tool is useful for:

• Budgeting – Understanding true car ownership costs.

• Comparing Vehicles – Evaluating fuel-efficient vs. luxury cars.

• Financial Planning – Deciding whether to buy, lease, or use alternative transport.

2. Key Cost Components

A. Fixed Costs (Recurring, Regardless of Mileage)

1. Insurance – Annual premium based on coverage level.

2. Registration & Taxes – DMV fees, property tax (if applicable).

3. Depreciation – Loss in value over time (estimated resale value).

4. Financing (Loans/Leases) – Monthly payments + interest.

B. Variable Costs (Depend on Mileage & Usage)

1. Fuel – Based on MPG and gas/electricity prices.

2. Maintenance & Repairs – Oil changes, tires, brakes, unexpected fixes.

3. Tires – Replacement every 30,000–50,000 miles.

4. Parking & Tolls – Daily parking fees, highway tolls.

3. How the Calculator Works

A. Input Parameters

1. Vehicle Details

   • Make, model, year

   • Fuel type (gas, diesel, hybrid, electric)

   • Fuel efficiency (MPG or kWh/100km)

2. Usage Data

   • Annual mileage

   • City vs. highway driving %

3. Cost Assumptions

   • Fuel/electricity price

   • Insurance cost

   • Maintenance estimates (e.g., $0.10/mile for repairs)

   • Depreciation rate (e.g., 15–20% per year)

B. Calculations

1. Annual Fuel Cost = (Miles Driven / MPG) × Fuel Price

2. Maintenance Cost = Miles Driven × Cost Per Mile (e.g., $0.10)

3. Depreciation Cost = (Initial Value - Resale Value) / Ownership Years

4. Total Annual Cost = Fuel + Maintenance + Insurance + Depreciation + Tires + Parking/Tolls

5. Cost Per Mile = Total Annual Cost / Miles Driven

C. Example Calculation

Car: 2020 Toyota Camry (30 MPG, $25,000 purchase price)
Annual Mileage: 12,000
Assumptions:

• Gas price: $3.50/gallon

• Insurance: $1,200/year

• Maintenance: $0.10/mile

• Depreciation: 15% per year

• Tires: $800 every 40,000 miles

Calculations:

1. Fuel Cost = (12,000 / 30) × $3.50 = **$1,400**

2. Maintenance = 12,000 × $0.10 = **$1,200**

3. Depreciation = $25,000 × 15% = **$3,750**

4. Tires = (12,000 / 40,000) × $800 = **$240**

5. Total Annual Cost = $1,400 + $1,200 + $3,750 + $240 + $1,200 (insurance) = **$7,790**

6. Cost Per Mile = $7,790 / 12,000 = **$0.65/mile**

4. Advanced Features

• EV vs. Gas Comparison – Include electricity rates, battery degradation.

• Lease vs. Buy Analysis – Compare lease payments vs. loan + depreciation.

• Public Transport vs. Car – Is Uber/transit cheaper than owning?

• Tax Deductions – Business mileage write-offs (IRS rate: $0.67/mile in 2024).
