Creation: 14 October 2026

The price on the sticker is often only half of a car's true five-year cost; the real calculation lies in the motor vehicle tax, insurance, and depreciation.

The hidden costs that must be calculated before buying a car extend far beyond the sticker price: when motor vehicle tax, mandatory traffic insurance and comprehensive coverage, fuel, periodic maintenance, tires, inspection, depreciation and potential loan interest are added together, the true cost of a vehicle often goes beyond a simple markup on the sales price. This page offers a practical framework that lets you calculate the total monthly and annual burden before making the purchase decision.

Highlights

The MTV (motor vehicle tax) increase in 2026 18.95% has been applied; the lowest passenger car bracket for the first six months is 5,750 TL.
The traffic insurance ceiling price for a first-tier vehicle in Istanbul is 58,214 TL.
The average annual cost of car ownership in Türkiye is approximately 51,000 TL; annual expenses for gasoline cars can rise into the 80,000-100,000 TL range.
Depreciation in the first year 10-20% can range between.

Why Is the Sticker Price Only the Starting Point?

In my thirty-year career I have seen the same picture over and over: the buyer builds their budget based on the car's showroom price, and after taking the keys the expenses find them. The correct approach, however, is to look at the total cost of buying and using a car. This concept is known in the literature as the total cost of ownership; it covers all of fuel, maintenance, motor vehicle tax, insurance, depreciation and potential repairs. In the past only gasoline and oil changes were considered; now the number of items that must be factored in has grown considerably.

As for what the numbers say: the average total annual cost of a car has been calculated at around 51,000 TL - that is more than two months of an average salary. More detailed calculations show that annual expenses for gasoline cars start at roughly 80,000 TL and approach the 100,000 TL level depending on the vehicle class. The difference between them is not an exaggeration; it depends on which items are included. One calculation adds depreciation, the other sums only the expenses actually paid out. Both methods are valid; however, when building your own budget, you must know which one you are using.

Fixed and Paid: Motor Vehicle Tax and Insurance

No matter how long a vehicle sits parked, certain items fall due once a year. The oldest and most certain of these is the Motor Vehicle Tax. The 2026 MTV amounts, in accordance with the Presidential Decree, 18.95% increase and are bracketed by vehicle age, engine displacement and taxable value. To give an example: 1300 cm³ and below cars have annual amounts by age of 5,750 / 4,010 / 2,238 / 1,689 TL; in the 1301-1600 cm³ range, they are 10,016 / 7,510 / 4,354 / 3,077 TL. In other words, moving to a car with a larger engine on the same budget pushes up not only fuel but also the motor vehicle tax.

Engine Displacement	Annual MTV Amounts (by age)
1300 cm³ and below	5,750 / 4,010 / 2,238 / 1,689 TL
1301-1600 cm³	10,016 / 7,510 / 4,354 / 3,077 TL
Lowest bracket (first 6 months)	5,750.00 TL

Since the exact amount varies from vehicle to vehicle, the healthiest approach is to calculate your own vehicle's tax value through the official inquiry tool. Because the bracket details in secondary calculation sites' tables can differ, checking the official source before making a final decision prevents unnecessary surprises.

On the insurance side there are two separate products, and they cover different things: mandatory traffic insurance covers material and bodily damage that may be inflicted on third parties, while comprehensive insurance (kasko) covers the vehicle's own damage. The price of traffic insurance varies across a very wide range depending on your claims history (your step code), the province you reside in and the vehicle type. In 2026 the top price for step 0 in Istanbul is 58,214 TL, in Ankara 56,566 TL, in Izmir 54,919 TL. Top prices are updated every month with a 5% inflation adjustment; moreover, the table differs entirely by vehicle type - in the Bursa example, the taxi ceiling can rise to 134,420 TL, the minivan ceiling to 66,690 TL, and the motorcycle ceiling to as much as 20,798 TL. For this reason, do not trust a figure called the "average traffic insurance premium"; get a quote for your own profile.

Mileage-Based Costs: Fuel, Maintenance, Tires and Inspection

Arabanın gerçek fiyatı etikette değil, her kilometrede saklıdır; yakıt, lastik ve bakım onu sessizce yeniden yazar.

The second group of expenses are the items that grow the more you use the vehicle. Fuel is the most obvious one; the calculation formula is simple: divide the annual mileage by 100, multiply by the vehicle's consumption per 100 kilometers, add the fuel price and divide by 12 - there is your monthly fuel budget. The most classic mistake here is trusting the factory value in the brochure. In city traffic, real consumption easily exceeds the catalog value; write an honest average based on your own habits.

Periodic maintenance and tires are less visible but arrive regularly. If you want to calculate the tire cost honestly, you can divide by the tire's average kilometer lifespan to derive a per-km cost - a far less painful method than suddenly having to come up with the money for four tires. The inspection cost is especially relevant on the second-hand market: if the inspection period has expired during the ownership transfer, the inspection fee and most likely an initial service (oil, filters) will be waiting for you before the vehicle hits the road. Parking fees, bridge and highway tolls, washing and cosmetic care are also part of the same item; when you add them up over a year, the seriousness of the matter becomes clear.

The Most Invisible Item: Depreciation

Most calculation tools factor in depreciation at a default 10% per year rate; in the first year the loss can range between 10-20% depending on the brand and segment. This is not money out of your pocket, but it is money that will not reach your pocket on the day you sell the vehicle - an item anyone doing an ownership cost analysis should include. It must also be added honestly: not every calculator agrees. Some explicitly state that they exclude second-hand depreciation and the opportunity cost of capital, and that the result is an "expense view". In other words, the monthly total given by a calculation tool may not be the full economic cost; check what is included.

Depreciation has another face on the used-car side: a vehicle with an accident or damage record reflects the price of that history in its sale price. Accounting for this item at the time of sale, if not at purchase, is part of the total cost.

Buying on Credit: How Do Installments and Interest Factor Into the Calculation?

The budget analysis should be done based on the total of the loan installment plus monthly running costs, without mixing the two up. Most calculation tools place the installment not under the main cost but under a separate "budget outflow including loan" line item; the reasoning is sound: the principal portion of the installment is not a consumed expense but a financing cash outflow. In other words, if your total monthly outflow is 25,000 TL, track separately how much of it is the cost of using the vehicle and how much is debt repayment.

The rules of consumer vehicle loans also directly affect the budget. According to BDDK regulations, down payment rates vary by vehicle price: 800,000-1,200,000 TL vehicles have a maximum down payment of %30, 1,200,000-2,000,000 TL in the range of %20. For lower-value vehicles, banks can offer up to 70% loans and terms such as 48 months ; for new vehicles it is usually possible to find longer terms and lower interest, while for used vehicles conditions vary from bank to bank. Vehicle loan interest rates are often more favorable than consumer loans; nevertheless, total interest grows as the term lengthens. Let us also add a note for companies: an expense restriction applies to passenger cars acquired after 07/12/2019, and how the loan interest of the vehicle added to assets will be treated is a matter of tax rulings - corporate buyers should not sign an offer without speaking to their accountant.

New or Used: A Comparison in Terms of Cost of Ownership

The difference between the two options is not only the purchase price; the ownership profile also takes a completely different shape. A new vehicle offers a more predictable start: repair risk is low in the first years, there is a warranty, and the maintenance schedule is in your hands. A used vehicle, on the other hand, allows moving up to a higher segment with the same budget - but it carries additional items such as transfer and notary costs, inspection fees, possible first maintenance-repair, and the risk of depreciation stemming from damage history.

Criterion	New Vehicle	Used Vehicle
Purchase price	High	Lower, moving up to a higher segment is possible
First-year maintenance-repair risk	Low, under warranty	First maintenance and repair costs are likely
Additional purchase costs	Standard transfer and insurance	Transfer, inspection, periodic inspection, first maintenance
Depreciation	10-20% in the first year	Damage history can deepen the loss

A note for those looking at electric vehicles: battery replacement cost is not a regular monthly bill; however, it can be added to the calculation as a theoretical reserve for planning purposes - depending on whether the battery's mileage or calendar life runs out first. Charging cost takes the place of the fuel item in gasoline vehicles, but the maintenance discipline and tax regime remain the same.

How Do You Calculate Your Own Total Cost Before Making a Purchase Decision?

The essence of the matter is to separate it into these three layers. First, gather the fixed items: MTV (from the official query tool), traffic insurance and comprehensive insurance quotes, annual maintenance amount, depreciation. Then add the variables: fuel based on kilometers and consumption, tire cost divided by km lifespan, inspection, parking and highway tolls. Write the loan installment as a separate line and calculate the "budget outflow including the loan" separately.

Fixed items: MTV + (comprehensive and traffic insurance)/12 + maintenance/12 + monthly depreciation
Variable items: fuel, tire wear, inspection, parking, bridges and highways
To be tracked separately: loan installment and interest burden
For used cars, add: transfer fees, expert inspection, possible first maintenance-repair

When you divide the total into a monthly figure, you are left with a single number showing how much you will really pay per month for this car. Comparing this number with a level your household budget can comfortably handle is a far more honest measure in a car purchase decision than the showroom price. Do the math first, choose the car later - that is the order.
