Depreciation vs Running Costs

Depreciation42%
Fuel24%
Insurance19%
Upkeep + fees15%

Formula

Total cost of ownership adds the silent cost (depreciation) to the visible ones (fuel, insurance, maintenance, fees). Depreciation usually dominates early; running costs dominate late.

TCO = depreciation + (fuel + insurance + upkeep + fees) × years

Variables

SymbolNameUnitDescription
DDepreciationcurrencyValue consumed over the holding period
OOperating totalcurrencyAll running costs summed over the years
TCOTotal costcurrencyThe full price of owning and running the car

Explanation

This is everything the car consumes — value plus running costs — expressed as a total, a monthly average and a per-mile rate.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Estimate depreciation from the declining-balance curve.

Depreciation = price − price × (1 − rate)^years
Result: $19,470 lost
Step 2

Add up every year of running costs.

Operating = (fuel + insurance + upkeep + fees) × years
Result: $26,750
Step 3

Combine both halves and divide by time and miles.

Total = depreciation + operating
Result: $46,220 total, $770.34 /month
Final Answer
$46,220

Scenario

The total cost of car ownership calculator run on the values above, showing the full calculation path rather than only the answer.

Inputs

Vehicle Price:35000
Annual Depreciation Rate:15
Vehicle Age:5
Annual Mileage:12000

Calculation

1. Estimate depreciation from the declining-balance curve. → $19,470 lost 2. Add up every year of running costs. → $26,750 3. Combine both halves and divide by time and miles. → $46,220 total, $770.34 /month

Result

Total Cost of Ownership: $46,220

Interpretation

$46,220 over 5 years ($770.34 /month, $0.77 /mi): $19,470 depreciation + $26,750 running costs.

Understanding Your Result

Your Result: Total Cost of Ownership: $46,220

Typical range: Ownership typically runs $0.50–$0.90 per mile for mainstream cars; depreciation alone is often half the total.

What This Means

This is everything the car consumes — value plus running costs — expressed as a total, a monthly average and a per-mile rate.

Why It Matters

$46,220 over 5 years ($770.34 /month, $0.77 /mi): $19,470 depreciation + $26,750 running costs.

Professional Interpretation

$46,220 over 5 years ($770.34 /month, $0.77 /mi): $19,470 depreciation + $26,750 running costs.

How this is calculated

Total cost of ownership adds the silent cost (depreciation) to the visible ones (fuel, insurance, maintenance, fees). Depreciation usually dominates early; running costs dominate late.

What drives the result

Vehicles are depreciating assets bought with amortising debt or priced as leases. Because interest is charged on the outstanding balance and depreciation is steepest in year one, the down payment, the term and the money factor matter far more than most buyers expect. Total cost of ownership — depreciation plus running costs — is the only number that captures the whole decision.

Recommendations

  • •Depreciation dwarfs fuel — buying slightly used saves more than hypermiling.
  • •Insurance and maintenance quotes vary wildly; price them before you buy, not after.

Educational Content

Introduction

A car deal is three negotiations wearing one price tag: the vehicle price, the financing or lease terms, and the trade-in value. Each has its own maths, and dealers profit most when buyers only watch the monthly payment. These calculators separate the three so every figure can be checked independently.

Concept Explanation

Vehicles are depreciating assets bought with amortising debt or priced as leases. Because interest is charged on the outstanding balance and depreciation is steepest in year one, the down payment, the term and the money factor matter far more than most buyers expect. Total cost of ownership — depreciation plus running costs — is the only number that captures the whole decision.

Applications

▸Sizing a down payment so the loan stays smaller than the car’s value
▸Checking a dealer lease quote by rebuilding the payment from cap cost, residual and money factor
▸Deciding whether to trade in, sell privately, or keep the old car
▸Comparing an EV’s charging savings against its higher purchase price and insurance

Benefits

  • •Rebuilds dealer quotes from first principles instead of trusting the payment presentation
  • •Shows the finance charge, not just the monthly payment
  • •Puts leases and purchases on one comparable total-cost basis
  • •Separates depreciation from running costs so the real expense is visible

Limitations

  • •Assumes fixed rates, on-time payments and the depreciation rate you enter
  • •Dealer fees, add-ons and tax rules vary by state and are only as accurate as your inputs
  • •Insurance estimates are indicative — real quotes depend on record, garaging and cover choices
  • •Market values move with fuel prices, incentives and model reputation

Best Practices

  • •Negotiate price, financing and trade-in as three separate deals
  • •Put at least 20% down (cash plus trade equity) to stay ahead of depreciation
  • •Convert every money factor to an APR before comparing with loan offers
  • •Price insurance before signing — it can differ by thousands between similar cars

Common Misconceptions

Myth: The monthly payment is the price of the car
Truth: The payment hides the term, the rate and the fees. The finance charge and total cost are the price.
Myth: Leasing is always more expensive than buying
Truth: Over three years with low mileage, leasing is often cheaper; buying wins when you keep the car long term.

Practical Tips

  • •Compare per-mile figures when mileages differ between options.
  • •Get insurance quotes before buying — the spread between similar cars shocks most buyers.

Common Mistakes

Budgeting fuel but forgetting depreciation
A “cheap” thirsty old car can cost more per mile than a new efficient one.
Using the loan term as the horizon
Ownership cost should follow how long you keep the car, not how long you finance it.

Assumptions

This calculator makes the following assumptions to provide estimates:

Smooth depreciation and flat running costs: Real costs spike with repairs; the average smooths them.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Assumes fixed rates, on-time payments and the depreciation rate you enter
Limitation: Dealer fees, add-ons and tax rules vary by state and are only as accurate as your inputs
Limitation: Insurance estimates are indicative — real quotes depend on record, garaging and cover choices
Limitation: Market values move with fuel prices, incentives and model reputation

Frequently Asked Questions

Answers to common questions about this calculator.

What costs most in car ownership?
Depreciation — often half the total over five years — followed by fuel and insurance.
How do I compare two cars fairly?
Run both over the same years and miles here; purchase price alone decides almost nothing.
Who uses the total cost of car ownership calculator?
It is used by car buyers checking a dealer quote before signing, by owners planning a payoff or trade-in, and by planners comparing options. It sits in the Ownership & Valuation group of the Auto Finance section of Atlascalcs.
How accurate is the total cost of car ownership calculator?
Every figure follows directly from the inputs using standard mathematics for vehicle calculations, so it is accurate to the quality of the values you enter. All calculations run at full precision and round only for display.
How current are the rates and thresholds used here?
The calculator uses the figures you enter, so update the rate to your actual offer or current market quote. Ratio thresholds, poverty guidelines and programme rules reflect the conventions described in the references and change periodically.
Does rounding change the results?
Every calculation runs on full precision and rounds only for display. Lenders round payments to the nearest cent or dollar, so expect a small difference between these figures and a formal statement or payoff quote.
Should I use the payment or the total cost to compare offers?
Use the payment to judge cash flow and the finance charge or APR to judge cost. When two offers differ on both, the all-in cost over the period you expect to hold the loan is the decisive measure.
Can I use this calculator for a business or commercial loan?
Yes. The payment, amortisation, ratio and cost calculators apply the same amortisation mathematics to commercial loans; the difference is in the fees, covenants and collateral rules, which you should enter explicitly.
What information should I have ready before applying?
Your exact rate and term, the fee schedule, any required add-ons, and your gross income and existing monthly obligations. With those five numbers every figure on this page can be tied back to a lender quote.
