Input Values

Monthly Insurance: 120$
Monthly Parking: 150$
Monthly Loan Payment: 0$
Monthly Registration: 20$
Fuel Cost Method: true
Fuel Price Per Unit: 3.5$
Fuel Consumption: 28units per 100 miles
Monthly Mileage: 1,000miles
Monthly Maintenance: 50$
Monthly Repairs: 0$
Other Monthly Costs: 0$

Calculation Steps

  1. Fixed costs: Insurance $120 + Parking $150 + Loan $0 + Registration $20 = $290/month
  2. Monthly mileage: 1,000 miles

  5. Variable costs: Fuel $125 + Maintenance $50 + Repairs $0 + Other $0 = $175/month
  6. Total monthly cost: $290 (fixed) + $175 (variable) = $465.00/month
  7. Cost per day: $465 ÷ 30 days = $15.50/day
  8. Cost per mile: $465 ÷ 1,000 miles = $0.465/mile
