Should You Sell Your Car or Keep It? Calculating the Right Time

The correct answer to the question of whether to sell the car or keep it lies not in a single figure, but in the difference between two cost columns: the disposal and renewal costs of selling the car and moving to a new one are compared against the annual operating cost of continuing to use it, and a threshold calculation reveals which option is more advantageous. In this article, we build that calculation step by step.

How to Decide: A Two-Column Cost Comparison

I have been in this business for over thirty years, and one thing has not changed: people often make the decision to replace a vehicle based on emotions, thinking about costs last. Yet the question is a very clear accounting question. Is the total cost of keeping your current car for one more year higher, or is it the cost difference of selling it and moving to a new one? To find the answer, you need to break both sides down into their components and write them on the same sheet of paper.

The first column is the annual cost of keeping the current vehicle: fuel, MTV, traffic insurance, comprehensive insurance, periodic maintenance, tires, inspection, and unexpected repairs. If there is a loan payment, it also goes into this column. The second column is the disposal side: how much will be deducted from the sale price, how much will expenses such as notary fees and inspection cost, and how much will the vehicle to be purchased itself cost? If you cannot compare the two columns, your decision is still merely an impression - not a calculation.

How to Calculate the Real Annual Cost of a Vehicle?

The total cost of ownership, known in the literature as TCO, is the sum of the vehicle's purchase price and its annual operating expenses. Looking only at the sticker price when making a purchase decision is like looking only at the main course at a restaurant; the bill takes shape according to what you have alongside it. The monthly cost components are listed as follows: energy, taxes, insurance, maintenance, inspection, tires, and daily expenses; if there is a loan payment, it is added on top.

To make this total meaningful, the most useful metric is cost per kilometer. The formula is simple: dividing annual total expenses by annual kilometers. A vehicle that spends 50,000 TL per year and drives 15,000 km per year produces a cost of approximately 3.33 TL per kilometer. If you do not know the annual average kilometers, it is enough to look at the odometer and divide the total kilometers by the age of the vehicle; this figure serves you both in the cost calculation and in the valuation comparison.

When it comes to the decision moment, the calculation goes one step further: the sum of the purchase price, registration, comprehensive insurance, motor vehicle tax, traffic insurance, fuel, maintenance and other expenses gives the cost of keeping the car; subtracting this total from the selling price shows the profit or loss. For someone who repeats this line at the beginning and end of every year, it is not hard to answer when asked whether it makes sense to sell the car or keep it.

What Changes as a Vehicle Ages?

In the past, when a car reached its fourth or fifth year, little expense was expected beyond oil, filters and brake pads; today's equipment density, along with the increase in safety and comfort technologies, means unexpected expenses also age with the vehicle. Tires appear as a serious line item every four years, the periodic inspection is an annual obligation, and in a car with rising mileage the scope of periodic maintenance expands. As our digest also points out, there is no quantitative table specific to Türkiye for this increase; therefore the honest method is to extract your actual expenses from the last two years from bank records and add a repair allowance of 10-15% for the coming year. What matters is not hitting the exact cent, but seeing the upward trend.

How to Read the Depreciation Curve?

Second-hand value does not fall in a straight line over time, but along a curve steep at the front. To illustrate with the declining balance method: a vehicle equivalent to 850,000 TL at the end of the first year is at a level of roughly 722,500 TL at the end of the second year; the decline continues, but the absolute loss shrinks each year. This is exactly why the most expensive moment to make the selling decision is during the vehicle's young years. Keeping it a few more years allows you to stay in the region where depreciation calms down.

Of course, what determines the position of the curve is not just age and mileage. In Türkiye, second-hand value varies by brand recognition, model popularity, engine option and fuel type; a model with high resale potential is a silent but decisive advantage in total cost. Let me also clearly address one point: "loss of value" in the context of post-accident compensation is a concept entirely separate from the natural wear discussed here; the former is a compensation matter tied to damage, the latter is the inevitable result of time and use. Calculations that confuse the two terms produce wrong decisions.

Car prices have fallen behind inflation and gold; the car is no longer an investment vehicle.

This observation sums up the essence of the decision: cars once kept with the thought that "a car makes money" must now be managed as an operating expense item. A car kept with investment expectations is an asset that writes costs to you.

Selling Costs: How to Calculate Notary Fees in 2026?

Be aware of the biggest line item on the seller's side: as of January 1, 2026, the fixed notary transfer fee has been abolished, and the notary sales duty is charged at a rate of 2 per thousand based on the vehicle's sale price - or, if the price is high, on its comprehensive insurance value. So for a vehicle you sell for 500,000 TL, you pay roughly 1,000 TL in duty; as the sale price grows, this line item grows. For comparison: in 2025, this transaction was handled with a fixed fee of 1,489.36 TL; now there is a structure where you pay more for high-value vehicles and less for lower-value ones.

What you need to have with you for the notary sale: the vehicle registration certificate, ID, a current periodic inspection certificate, and valid mandatory traffic insurance. Besides the duty, the inspection fee and, if not yet paid, the current Motor Vehicle Tax obligation also enter the sales costs. Used passenger cars are commercially handled either on commission or through the dealership's own name and account; whichever channel you go through, it is essential to deduct these expenses from the sale price to calculate what you actually take home. Note one detail too: under the regulation on second-hand trade, the statutory warranty applies to vehicles under 8 years old and 160,000 km; above these limits, no warranty advantage is discussed on the buyer's side - that is, your side.

Should You Sell to a Dealership or Privately?

The sales channel directly affects the money you take home, and the two pay in different currencies: one is speed, the other price. Selling to a dealership concludes with cash payment within 1-7 days and requires no effort; but due to the dealership's profit margin, you may receive an offer 10-20% below market value. For a vehicle with a market value of 800,000 TL, that means an offer between 640,000-720,000 TL - the loss is the price of speed. In a private sale, the cost table reverses: the price stays close to market value, and total expenses usually remain around 2-5% of the value; in return, you spend 2-8 weeks, listing fees, and the effort of negotiation.

There is also a hybrid path between the two extremes: getting a dealership offer while listing at the same time. But be careful - if the contract you sign with the dealership contains an "exclusive sale" clause, the vehicle cannot be sold through another channel. On the negotiation side, an old rule still holds: setting the listing price 5-10% above market value in a private sale gives you room for incoming offers. As for safety, one sentence suffices: fake bank transfer receipts and disinformation SMS messages are a widespread fraud method; do not hand over the vehicle keys before you see the money arrive in your account through your banking app.

Fixed Costs of Keeping It: Motor Vehicle Tax, Insurance, and Inspection

When you choose to keep the car, there are expenses you cannot escape, and some of them work in your favor with age. MTV (annual motor vehicle tax) is determined by the vehicle type, engine displacement, age, and value, and the age groups are divided into brackets of 1-3, 4-6, 7-11, 12-15, and 16+ years. As the age increases, the tax decreases gradually; the owner of a new car is in the highest bracket. For electric vehicles, the calculation is made based on motor power and the age and vehicle value bracket. In other words, keeping the car means a burden on the tax side that lightens over time.

On the insurance front, two separate obligations must be distinguished. Traffic insurance is mandatory and covers the damages of the other party, that is, third parties; its limits are set by the state every year. Casco (comprehensive) insurance is optional and protects against damages to your own vehicle such as theft, fire, or an accident while parked. The no-claims discount is the quiet hero of this equation: it can provide a discount of approximately 20% on traffic insurance and up to 60% on casco. Every year that passes without an accident shrinks the expense column of the decision to keep the car - and that is a saving method that requires no skill other than careful driving.

Threshold Calculation: The Point Where Selling Starts to Make Sense

Now, to the question this article is built around: how do you find the breaking point? It is possible to synthesize the formula from its components, and it works like this. In the first step, write down the total cost of ownership of your current vehicle for the coming year: expected fuel, MTV, insurances, maintenance schedule, tires and periodic inspection if applicable, plus a repair allowance. In the second step, calculate the net resale figure: from today's market value, subtract the 10-20% dealership commission or 2-5% private sale cost depending on the sales channel, the notary sales fee (2 per mille), and the inspection fee, and find the money you will receive net. In the third step, look at the first-year cost of the car you will buy - including the steepest part of the depreciation curve.

The decision rule is simple: If the new car's total first-year cost comfortably covers the current car's cost for the coming year, plus the annual share of disposal expenses within a payback period, then selling makes sense; if not, keep it. In practice, this rarely holds true for a car whose maintenance and repair costs are rising rapidly, whose value has just come off the steep part of the curve, and whose mileage exceeds your usage needs; for a car whose operating costs are reasonable and suited to your needs, selling almost never wins on paper - because every change re-invoices you for the next car's first-year depreciation and sales costs.

To learn your vehicle's value, you can use online valuation services that offer free valuations and instant quotes today, and take advantage of tools that calculate the total cost of ownership using 5-year depreciation, fuel, insurance, and tax inputs. If you are considering switching to electric, keep in mind that even though the initial purchase price may seem high, low operating and charging costs can change the overall picture; gasoline engines establish their own equation with low maintenance costs, while diesel does so with low consumption and long-range capability.

The Bottom Line: Don't Change Cars Without Calculating

The only certainty that long years have taught is this: the most expensive moment of changing a car is the moment when the decision is easiest to make. Write down the numbers - the cost per kilometer, the depreciation curve, the 2-per-mille fee, the silent 10-20% cut in the dealership's offer. If the difference between the two columns doesn't convince you, that car has earned its place in your garage for another year.
