Calculation Examples
Example 1: Compact Car, City Driving
Input Values
Calculation Steps
- Purchase price: $20,000
- Ownership period: 5 years
- Annual mileage: 10,000 miles
- Fuel calculation: 10,000 miles ÷ 30 MPG = 333.33 gallons/year × 5 years = 1,666.67 gallons total
- Total fuel cost: 1,666.67 gallons × $3.50/gallon = $5,833.33
- Fixed costs: Insurance ($1,200 × 5 = $6,000) + Registration ($150 × 5 = $750) + Parking ($150 × 12 × 5 = $9,000) = $15,750
- Maintenance: $600 × 5 = $3,000
- Repairs: $400 × 5 = $2,000
- Depreciation: $20,000 × 18% = $3,600 year 1, then compound for 5 years ≈ $12,500 total
- Total ownership cost: $5,833 (fuel) + $15,750 (fixed) + $3,000 (maintenance) + $2,000 (repairs) + $12,500 (depreciation) = $39,083
- Monthly cost: $39,083 ÷ 60 months = $651.38
- Cost per mile: $39,083 ÷ 50,000 miles = $0.78
Calculated Results
Example 2: SUV, High Mileage
Input Values
Calculation Steps
- Purchase price: $45,000
- Ownership period: 7 years
- Annual mileage: 20,000 miles (high mileage driver)
- Fuel calculation: 20,000 miles ÷ 20 MPG = 1,000 gallons/year × 7 years = 7,000 gallons total
- Total fuel cost: 7,000 gallons × $3.75/gallon = $26,250
- Fixed costs: Insurance ($2,000 × 7 = $14,000) + Registration ($300 × 7 = $2,100) + Parking ($0) = $16,100
- Maintenance: $1,200 × 7 = $8,400
- Repairs: $800 × 7 = $5,600
- Depreciation: $45,000 × 16% = $7,200 year 1, compound over 7 years ≈ $28,000 total
- Total ownership cost: $26,250 (fuel) + $16,100 (fixed) + $8,400 (maintenance) + $5,600 (repairs) + $28,000 (depreciation) = $84,350
- Monthly cost: $84,350 ÷ 84 months = $1,004.17
- Cost per mile: $84,350 ÷ 140,000 miles = $0.60
Calculated Results
Example 3: Used Car, Low Depreciation
Input Values
Calculation Steps
- Purchase price: $12,000 (used car, already depreciated)
- Ownership period: 4 years
- Annual mileage: 15,000 miles
- Fuel calculation: 15,000 miles ÷ 28 MPG = 535.71 gallons/year × 4 years = 2,142.86 gallons total
- Total fuel cost: 2,142.86 gallons × $3.25/gallon = $6,964.30
- Fixed costs: Insurance ($1,000 × 4 = $4,000) + Registration ($100 × 4 = $400) = $4,400
- Maintenance: $800 × 4 = $3,200
- Repairs: $600 × 4 = $2,400 (higher for used car)
- Depreciation: $12,000 × 12% = $1,440 year 1, compound over 4 years ≈ $4,800 total (much lower than new car)
- Total ownership cost: $6,964 (fuel) + $4,400 (fixed) + $3,200 (maintenance) + $2,400 (repairs) + $4,800 (depreciation) = $21,764
- Monthly cost: $21,764 ÷ 48 months = $453.42
- Cost per mile: $21,764 ÷ 60,000 miles = $0.36 (lower than new car due to reduced depreciation)
Calculated Results
Example 4: New Car, High Depreciation
Input Values
Calculation Steps
- Purchase price: $60,000 (new luxury car)
- Ownership period: 3 years (short-term ownership)
- Annual mileage: 8,000 miles (low mileage)
- Fuel calculation: 8,000 miles ÷ 22 MPG = 363.64 gallons/year × 3 years = 1,090.91 gallons total
- Total fuel cost: 1,090.91 gallons × $4.00/gallon = $4,363.64
- Fixed costs: Insurance ($3,000 × 3 = $9,000) + Registration ($500 × 3 = $1,500) + Parking ($200 × 12 × 3 = $7,200) = $17,700
- Maintenance: $1,500 × 3 = $4,500
- Repairs: $1,000 × 3 = $3,000
- Depreciation: $60,000 × 25% = $15,000 year 1, compound over 3 years ≈ $33,000 total (largest cost component)
- Total ownership cost: $4,364 (fuel) + $17,700 (fixed) + $4,500 (maintenance) + $3,000 (repairs) + $33,000 (depreciation) = $62,564
- Monthly cost: $62,564 ÷ 36 months = $1,737.89
- Cost per mile: $62,564 ÷ 24,000 miles = $2.61 (very high due to low mileage and high depreciation)
Calculated Results
Example 5: Mid-Range Sedan, Average Use
Input Values
Calculation Steps
- Purchase price: $28,000
- Ownership period: 6 years (longer ownership spreads costs)
- Annual mileage: 12,000 miles (average driver)
- Fuel calculation: 12,000 miles ÷ 26 MPG = 461.54 gallons/year × 6 years = 2,769.23 gallons total
- Total fuel cost: 2,769.23 gallons × $3.60/gallon = $9,969.23
- Fixed costs: Insurance ($1,400 × 6 = $8,400) + Registration ($200 × 6 = $1,200) + Parking ($50 × 12 × 6 = $3,600) = $13,200
- Maintenance: $700 × 6 = $4,200
- Repairs: $500 × 6 = $3,000
- Depreciation: $28,000 × 17% = $4,760 year 1, compound over 6 years ≈ $18,500 total
- Total ownership cost: $9,969 (fuel) + $13,200 (fixed) + $4,200 (maintenance) + $3,000 (repairs) + $18,500 (depreciation) = $48,869
- Monthly cost: $48,869 ÷ 72 months = $678.74
- Cost per mile: $48,869 ÷ 72,000 miles = $0.68
