1) Net signup fee
Net Signup Fee = max(Signup Fee − Promo Credit, 0)
2) Amortized signup per month
Amortized Signup = Net Signup Fee ÷ Contract Months

Overage Miles = max(Expected Miles Per Month − Included Miles Per Month, 0)
4) Monthly overage cost
Overage Cost = Overage Miles × Overage Charge Per Mile
5) Deposit carrying cost
Deposit Carry = (Refundable Deposit × Annual Opportunity Rate ÷ 100) ÷ 12
6) Monthly swap cost
Swap Cost = (Swap Fee Per Swap × Swaps Per Year) ÷ 12
7) Taxable monthly subtotal
Taxable Subtotal = Subscription Fee + Amortized Signup + Overage Cost + Non-Covered Maintenance + Non-Covered Roadside + Swap Cost
8) Monthly tax
Monthly Tax = Taxable Subtotal × Tax Rate ÷ 100
9) Total monthly cost
Total Monthly Cost = Taxable Subtotal + Monthly Tax + Deposit Carry + Insurance + Fuel + Charging + Parking + Tolls + Cleaning + Miscellaneous
