Normalize before comparing
Set one ownership scenario for both vehicles
A fair comparison holds the driver’s life constant. Otherwise, different loan terms, mileage, energy prices, or ownership periods can manufacture a winner.
Shared five-year assumptions
Separate universal costs from vehicle differences
Parking and tolls may be identical for both vehicles, but fuel type, insurance premium, tire cost, maintenance schedule, registration method, charging needs, depreciation, and financing can differ substantially.
Start with the complete deal
Compare acquisition and financing, not MSRP alone
Use itemized quotes for the exact configurations. Remove trade-in and down-payment differences from the vehicle comparison unless you intentionally want to model cash-flow choices.
| Acquisition input | Vehicle A | Vehicle B |
|---|---|---|
| Year / make / model / trim | ________________________ | ________________________ |
| VIN or representative configuration | ________________________ | ________________________ |
| MSRP | $ __________________ | $ __________________ |
| Negotiated selling price | $ __________________ | $ __________________ |
| Eligible incentives | $ __________________ | $ __________________ |
| Dealer add-ons | $ __________________ | $ __________________ |
| Dealer and government fees | $ __________________ | $ __________________ |
| Sales / use tax | $ __________________ | $ __________________ |
| Itemized OTD price | $ __________________ | $ __________________ |
| Cash down used in model | $ __________________ | $ __________________ |

| APR / term | _____ % / _____ months | _____ % / _____ months |

Use the new car quote comparison guide to make sure the two OTD totals include equivalent items and conditions.
The cost to live with it
Five-year operating-cost worksheet
Use manufacturer schedules, insurer quotes, vehicle-specific tire prices, local energy costs, and your expected mileage. Label estimates rather than presenting them as guaranteed costs.
| Five-year cost category | Vehicle A | Vehicle B | Evidence / assumption |
|---|---|---|---|
| Insurance premiums | $ ______________ | $ ______________ | Matched quote and coverage |
| Gasoline / diesel | $ ______________ | $ ______________ | Miles ÷ realistic MPG × price |
| Home electricity | $ ______________ | $ ______________ | kWh/mile × miles × rate |
| Public / fast charging | $ ______________ | $ ______________ | Expected share and price |
| Home charging equipment / installation | $ ______________ | $ ______________ | Net equipment and electrical work |
| Scheduled maintenance | $ ______________ | $ ______________ | Owner schedule and local prices |
| Expected tires | $ ______________ | $ ______________ | Size, wear, quantity, installation |
| Expected repairs after coverage | $ ______________ | $ ______________ | Scenario estimate |
| Registration / property taxes | $ ______________ | $ ______________ | State and local method |
| Parking / permits / toll differences | $ ______________ | $ ______________ | Include only true differences |
| Other vehicle-specific costs | $ ______________ | $ ______________ | Accessories, subscriptions, fluids |

Usually the largest hidden cost
Estimate value loss with a range
Future resale value is uncertain. Treat depreciation as a scenario, not a precise promise, and use mileage and condition assumptions that match your actual plan.
Conservative exit scenario
Model weaker resale demand, higher mileage, ordinary cosmetic wear, or a less favorable market. This tests downside risk.
Evidence-based midpoint
Use current multi-source residual estimates or comparable older models, then document how the estimate was adjusted for mileage and condition.
Optimistic exit scenario
Model stronger demand and excellent condition, but do not select this value merely to make a preferred vehicle win.
| End-of-year-five value | Vehicle A | Vehicle B |
|---|---|---|
| Conservative resale / trade value | $ __________________ | $ __________________ |
| Expected resale / trade value | $ __________________ | $ __________________ |
| Optimistic resale / trade value | $ __________________ | $ __________________ |
| Estimated remaining loan payoff | $ __________________ | $ __________________ |
| Expected net equity | $ value − payoff = __________ | $ value − payoff = __________ |
| Expected depreciation | $ acquisition basis − value = __________ | $ acquisition basis − value = __________ |
One decision page
Complete the five-year ownership comparison
Use consistent accounting. One simple method adds net acquisition and operating costs, then subtracts the end value you expect to realize. If a loan remains, ensure the payoff is not omitted or double-counted.
| Five-year summary | Vehicle A | Vehicle B |
|---|---|---|
| OTD price | $ __________________ | $ __________________ |
| Financing cost during ownership | + $ ______________ | + $ ______________ |
| Total operating costs | + $ ______________ | + $ ______________ |
| Other ownership costs | + $ ______________ | + $ ______________ |
| Expected resale / trade value | − $ ______________ | − $ ______________ |
| Remaining payoff if not already counted | + $ ______________ | + $ ______________ |
| Estimated five-year ownership cost | = $ ______________ | = $ ______________ |
| Estimated cost per mile | $ total ÷ miles = ______ | $ total ÷ miles = ______ |
Decision record
Use cost to clarify, not erase, preferences
If the estimated difference is small relative to the uncertainty, comfort, safety, reliability, cargo needs, charging access, towing, or family fit may reasonably decide the purchase.
Common questions
Car total cost of ownership FAQs
What costs should be included in car ownership?
Include acquisition, financing, depreciation, insurance, fuel or electricity, maintenance, repairs, taxes, registration, parking, tolls, charging equipment, subscriptions, and vehicle-specific costs relevant to your use.
Is depreciation part of total cost of ownership?
Yes. Value loss is often a major ownership cost. Estimate it using acquisition basis minus realistic end value, while avoiding double-counting loan payoff.
How do I compare a gas car with an electric vehicle?
Use the same mileage and period, then compare gasoline, home and public charging, charging equipment, maintenance, insurance, incentives, registration, financing, and expected resale value.
Should I use MSRP or out-the-door price in the worksheet?
Use an itemized out-the-door price for acquisition comparison because MSRP excludes negotiated differences, incentives, add-ons, dealer fees, taxes, and registration.
How can I estimate future resale value?
Use multiple current sources, comparable older models, mileage and condition adjustments, and low, expected, and high scenarios. Treat every result as an estimate.
Does a lower monthly payment mean a lower ownership cost?
No. Payment can be reduced by a longer term or larger down payment, while depreciation, interest, fees, energy, insurance, and other costs remain.
What if one vehicle costs more but fits me better?
Record the estimated cost difference and the practical benefit. If the difference is affordable and the benefit is material, total cost can inform the decision without dictating it.
