Colocation or Dedicated Server? TCO Comparison 2026

"Wouldn't it be cheaper if we bought the server?" This question gets asked in almost every growing infrastructure team, and the answer is not as clear as it seems. Buying the hardware and placing it in a data center (colocation) saves half over three years in some scenarios; in others it turns out more expensive than renting. The deciding factor is the class of server. In this article we compare the two models over a 36-month total cost of ownership (TCO), with real prices.

Short answer: On high-end hardware (Ryzen 9 class and above), colocation reaches break-even in about 14 months and saves more than 40% over 36 months. On entry-level hardware, renting is almost always cheaper, because the monthly colocation fee is close to the price of a dedicated server. The rough threshold is this: if the monthly rent is below 8,000₺, do not move to colocation.

The Cost Structure of the Two Models

For the comparison to be meaningful, it needs to be clear which item belongs to whom.

Item Colocation Dedicated rental
HardwareOne-off investment (CAPEX), you own itNone — belongs to the provider
Monthly expenseRack + power + networkA single rental item (all inclusive)
Failure riskYours — you supply the spare partWith the provider
UpgradesYou buy and fit the part; full controlPlan change, usually the same day
AccountingDepreciation + expenseEntirely a direct expense
ExitThe hardware stays with you (second-hand value)The contract ends, no obligations remain
Calculation assumption: The hardware prices in the scenarios below are examples. Because component prices and exchange rates change constantly, repeat the calculation with the real figures from your own quote. The colocation and rental prices are SistemDC's current list prices.

Scenario A: A Single High-End Server

A Ryzen 9 9950X-class system. The rental equivalent is 15,000₺/mo; on the colocation side, a 1U shared rack is 4,500₺/mo. The hardware investment is taken as 150,000₺ as an example.

  Starter Monthly 12 months 36 months
Dedicated rental0 ₺15,000 ₺180,000 ₺540,000 ₺
Colocation (1U)150,000 ₺4,500 ₺204,000 ₺312,000 ₺
Difference—10,500 ₺ in favour24,000 ₺ against228,000 ₺ in favour

At a saving of 10,500₺ a month, the 150,000₺ investment is paid back in about 14.3 months of operation. In the twelfth month colocation is still behind; from the fifteenth month it pulls ahead and by the end of 36 months it saves 42%. On top of that, because the hardware stays with you, there is a second-hand value we have not included in the calculation.

Scenario B: An Entry-Level Server — Why Does Colocation Not Make Sense?

Let us do the same calculation with a Ryzen 5-class system. The rental price starts from 2,900₺/mo. The base price of the colocation plan, however, is 4,500₺/mo.

Because the monthly colocation fee (4,500₺) is higher than the rent (2,900₺), a break-even point never occurs. Even if you got the hardware for free, colocation is 1,600₺ more expensive every month. In this segment the right decision is to rent.

A general threshold follows from this: if the monthly rent is not clearly above the colocation fee, the maths of colocation does not work. In practice, around 8,000₺/mo is a reasonable break point; renting should be considered for plans below it and buying for those above. You can check dedicated plan prices on the dedicated server page at any time.

Scenario C: Five Servers — The Rack Model

As scale grows, the gap widens in favour of colocation, because the rack cost is divided by the number of servers. Five high-end servers in a 10U rack:

  • Rental: 5 × 15,000₺ = 75,000₺/mo
  • Colocation: 10U rack 10,000₺ + power (5 × 250W = 1.25 kW → 900 kWh × 13₺ = 11,700₺) = 21,700₺/mo
  • Hardware investment: 5 × 150,000₺ = 750,000₺
  • Monthly difference: 53,300₺ — break-even ~14.1 months
  • 36-month total: Rental 2,700,000₺ • Colocation 1,531,200₺ • Saving 1,168,800₺

For the details of the power calculation and different power levels, see the rack rental prices guide for more. We diagrammed how five servers fit into a rack in the U calculation guide article.

Costs That Do Not Make It into the Table

The calculations above show direct cash flow. When deciding, the following items also need to be weighed:

  • Technology obsolescence: The processor you buy will be two generations behind in three years. With rental this risk lies with the provider; you move to the new generation by changing plans.
  • Spare parts and repair time: With colocation you supply the failed disk. On critical systems you need to keep spare disks and RAM at the facility in advance; that too is tied-up capital.
  • The opportunity cost of capital: The return on investing 750,000₺ in the product instead of tying it up in hardware should be taken into account.
  • Residual value: After three years the second-hand value of the hardware is added to the saving; this is an item in favour of colocation.
  • Operational burden: Responsibility for firmware, the RAID controller and hardware monitoring passes to you.

We covered the general framework of cost modelling in the server cost and TCO guide article.

Decision Matrix

Your situation Recommendation
The project is shorter than 12 months or the load is uncertainRental — you cannot reach the break-even point
Monthly rent is below 8,000₺Rental
You already have hardware in handColocation — the investment is sunk, the monthly expense falls
A production system with a steady load that will run for 3+ yearsColocation
Custom hardware is needed (special GPU, multi-disk chassis)Colocation — a configuration outside the catalogue
Cash flow is tight, CAPEX is difficultRental — all of it is expensed
5+ servers, continuously growing infrastructureRack rental + your own hardware
Traffic fluctuates, with seasonal peaksHybrid: base load on colocation, rental for peaks

The hybrid model in the last row gives the most efficient result in practice: you run the predictable base load on your own hardware and cover seasonal increases with monthly dedicated servers.

Frequently Asked Questions

How many months is the break-even point for colocation?
On high-end hardware it is typically between 12–18 months. The formula: hardware cost ÷ (monthly rent − monthly colocation fee).

Can I rent the hardware and put it in the data center?
In that case you are already on the dedicated rental model; you do not need to pay a separate colocation fee.

Which is more advantageous for tax purposes?
The whole rental fee is a period expense. Purchased hardware is subject to depreciation. The cash flow and balance sheet effects differ; we recommend evaluating this with your accountant.

How long does it take to move my existing server?
Setup and migration support from your old data center are free; the typical commissioning time is 24 hours.

What if I change my mind later?
Contracts are flexible from a 1-month trial period up to 36 months, with no early termination penalty. The hardware also stays with you.

Which Model Suits You?

If you have hardware, colocate it; if not, rent — both in the Istanbul data center, built to Tier 3 standards
