Calculation Examples
Example 1: City Commuter
Input Values
Calculation Steps
- Fixed costs: Insurance $120 + Parking $150 + Loan $0 + Registration $20 = $290/month
- Monthly mileage: 1,000 miles
- Fuel calculation: (1,000 miles ÷ 100) × 28 MPG = 35.71 gallons needed
- Fuel cost: 35.71 gallons × $3.50/gallon = $125.00/month
- Variable costs: Fuel $125 + Maintenance $50 + Repairs $0 + Other $0 = $175/month
- Total monthly cost: $290 (fixed) + $175 (variable) = $465.00/month
- Cost per day: $465 ÷ 30 days = $15.50/day
- Cost per mile: $465 ÷ 1,000 miles = $0.465/mile

Example 2: Car with Loan
Input Values
Calculation Steps
- Fixed costs: Insurance $180 + Parking $0 + Loan $450 + Registration $25 = $655/month
- Variable costs: Fuel $250 + Maintenance $80 + Repairs $0 + Other $30 = $360/month
- Total monthly cost: $655 (fixed) + $360 (variable) = $1,015.00/month
- Cost per day: $1,015 ÷ 30 days = $33.83/day
- Note: Loan payment is the largest fixed cost at $450/month
- Comparison: Without loan, monthly cost would be $565 (44% reduction)

Example 3: Older Car, Higher Repairs
Input Values
Calculation Steps
- Fixed costs: Insurance $90 + Parking $50 + Loan $0 + Registration $15 = $155/month
- Monthly mileage: 1,200 miles
- Fuel calculation: (1,200 miles ÷ 100) × 22 MPG = 54.55 gallons needed
- Fuel cost: 54.55 gallons × $3.75/gallon = $204.55/month
- Variable costs: Fuel $204.55 + Maintenance $100 + Repairs $75 + Other $0 = $379.55/month
- Total monthly cost: $155 (fixed) + $379.55 (variable) = $534.55/month
- Cost per day: $534.55 ÷ 30 days = $17.82/day
- Cost per mile: $534.55 ÷ 1,200 miles = $0.446/mile
- Note: Older cars have higher maintenance and repair costs, but no loan payment

Example 4: High Mileage Driver
Input Values
Calculation Steps
- Fixed costs: Insurance $150 + Parking $0 + Loan $300 + Registration $20 = $470/month
- Monthly mileage: 2,000 miles (high mileage driver)
- Fuel calculation: (2,000 miles ÷ 100) × 30 MPG = 66.67 gallons needed
- Fuel cost: 66.67 gallons × $3.60/gallon = $240.00/month
- Variable costs: Fuel $240 + Maintenance $120 + Repairs $0 + Other $50 = $410/month
- Total monthly cost: $470 (fixed) + $410 (variable) = $880.00/month
- Cost per day: $880 ÷ 30 days = $29.33/day
- Cost per mile: $880 ÷ 2,000 miles = $0.44/mile
- Note: High mileage increases fuel and maintenance costs significantly

Example 5: Minimal Expenses, Paid Off Car
Input Values
Calculation Steps
- Fixed costs: Insurance $80 + Parking $0 + Loan $0 + Registration $12 = $92/month
- Monthly mileage: 800 miles (low mileage driver)
- Fuel calculation: (800 miles ÷ 100) × 32 MPG = 25.00 gallons needed
- Fuel cost: 25.00 gallons × $3.50/gallon = $87.50/month
- Variable costs: Fuel $87.50 + Maintenance $40 + Repairs $20 + Other $0 = $147.50/month
- Total monthly cost: $92 (fixed) + $147.50 (variable) = $239.50/month
- Cost per day: $239.50 ÷ 30 days = $7.98/day
- Cost per mile: $239.50 ÷ 800 miles = $0.299/mile
