Car Subscription Comparison Calculator

Test three plans using fees, mileage, and extras. See total ownership-style costs clearly before subscribing. Find the most economical plan for your driving needs.

Calculator Inputs

Enter shared driving assumptions first, then fill in up to three subscription plans. The calculator evaluates total cost, effective monthly cost, and cost per mile.

Shared Assumptions

Plan 1
Plan 2
Plan 3
Results include recurring subscription charges, fuel, mileage overages, one-time fees, and sales tax. Refundable deposits appear in cash due at start but stay outside total cost.

Formula Used

Monthly Base Cost = Monthly Subscription Fee + Insurance + Maintenance + Registration + Other Monthly Services

Recurring Subtotal = Monthly Base Cost × Analysis Months

Monthly Fuel Cost = (Expected Monthly Miles ÷ Fuel Efficiency) × Fuel Price Per Gallon

Overage Miles Per Month = max(0, Expected Monthly Miles − Included Miles Per Month)

Overage Total = Overage Miles Per Month × Overage Cost Per Mile × Analysis Months

One-Time Fees = Start Fee + Delivery Fee + Return Fee + Non-Refundable Deposit

Tax Total = (Recurring Subtotal + One-Time Fees) × Tax Rate

Total Cost = Recurring Subtotal + Fuel Total + Overage Total + One-Time Fees + Tax Total

Effective Monthly Cost = Total Cost ÷ Analysis Months

Cost Per Mile = Total Cost ÷ Total Planned Miles

FAQs

1. What does this calculator compare?

It compares three car subscription offers using recurring charges, fuel costs, included mileage, overage fees, one-time fees, taxes, and startup cash requirements.

2. Does the calculator include fuel costs?

Yes. Fuel cost is estimated from your monthly miles, each plan’s fuel efficiency, and the fuel price per gallon you enter.

3. How are mileage overages handled?

The calculator measures any miles above the included monthly allowance, then multiplies them by the stated overage rate and analysis period.

4. Are refundable deposits counted as cost?

No. Refundable deposits are shown in the startup cash figure, but they stay outside total cost unless you mark them as non-refundable.

5. Why does cost per mile matter?

Cost per mile helps normalize offers with different fees and mileage limits, making it easier to compare value across very different subscription plans.

6. Can I compare plans with included insurance?

Yes. Enter zero for insurance, maintenance, registration, or other services when those items are already included in the subscription fee.

7. What period should I use for analysis?

Use a period that reflects how long you expect to keep the service. Longer periods reveal the impact of recurring fees more clearly.

8. Can I export the results?

Yes. After calculating, use the CSV button for spreadsheet work or the PDF button for sharing a clean summary report.
