Total Cost of Ownership Analysis

Build vs. Colo vs. Cloud

Compare 5-year and 10-year Total Cost of Ownership across deployment models with real market data from 12 global regions

The "build or buy" decision can swing tens of millions of dollars over a decade — and most spreadsheet models quietly ignore half the variables.

Should you build your own facility, lease colocation space, or go all-in on cloud? The answer depends on scale, growth trajectory, region, and dozens of cost levers most models skip. This calculator uses 2025-2026 market data from Turner & Townsend, CBRE, Cushman & Wakefield, and IEA to model construction costs, wholesale colo rates, cloud pricing, and year-over-year inflation for power, staffing, and maintenance. Pick your region, set your capacity, and see which model wins — and more importantly, when the crossover happens.

Deployment Region ?

Deployment Region

Select the market region for your data center deployment. Each region has unique construction costs, power rates, labor costs, and colocation pricing.

Region	Build $/MW
N. Virginia	$12.0M
Singapore	$14.5M
Tokyo	$15.2M
Mumbai	$7.5M

IT Load (MW) ?

IT Load (MW)

Total critical IT power capacity in megawatts. This drives all cost calculations.

Scale	MW Range
Small / Edge	1-3 MW
Mid-Market	3-10 MW
Enterprise	10-30 MW
Hyperscale	30-100 MW

Formula: CAPEX = MW x Cost/MW x Tier Mult

Analysis Period ?

Analysis Period

Timeframe for TCO comparison. Longer periods favor own-build due to CAPEX amortization. Cloud and colo costs compound annually.

Period	Favors
5 years	Colo / Cloud (lower upfront)
10 years	Build (CAPEX amortized)

Tier Level ?

Tier Level

Uptime Institute tier classification. Higher tiers add redundancy, increasing both CAPEX and staffing requirements.

Tier	Cost Mult / Staff/MW
Tier II	0.85x / 3 staff
Tier III	1.00x / 5 staff
Tier IV	1.35x / 8 staff

PUE Target ?

PUE Target

Power Usage Effectiveness. Ratio of total facility power to IT power. Lower = more efficient = lower power costs.

Rating	PUE Range
Excellent (DLC)	1.08-1.15
Good	1.15-1.30
Average	1.30-1.50
Poor	1.50-2.00

Formula: Total Power = IT Load x PUE

Power Utilization % ?

Power Utilization

Percentage of provisioned IT capacity actually in use. Affects actual power consumption and cost calculations.

Phase	Typical %
Day 1 (new build)	30-40%
Growth phase	50-70%
Mature	70-85%
Near capacity	85-95%

Cooling Type ?

Cooling Type

Cooling architecture affects PUE and construction cost. DLC enables lowest PUE but has highest CAPEX.

Type	Typical PUE
Air Cooled	1.40
Chilled Water	1.25
Evaporative	1.15
Direct Liquid	1.08

Annual Growth Rate % ?

Annual Growth Rate

Expected year-over-year growth in IT load. Affects future capacity needs and total cost trajectory.

Scenario	Growth %
Stable	0-5%
Moderate	5-15%
Aggressive	15-25%
Hyper-growth	25-30%

Growth compounds colo and cloud costs significantly

Land Cost Override ($/sqft) ?

Land Cost Override

Override the default regional land cost. Leave empty to use market data.

Market	$/sqft

Market	$/kWh
Dallas	$0.055

Staff Count Override ?

Staff Count Override

Override the auto-calculated staff count. Default is based on tier level and IT load.

Tier	Staff per MW
Tier II	3
Tier III	5
Tier IV	8

Colo Escalation %/yr ?

Colo Lease Escalation

Annual percentage increase in colocation lease rates. Market standard is 3% but varies by contract.

Scenario	Rate
Favorable	1-2%
Market Standard	3%
Tight Market	4-5%

Cloud Discount % ?

Cloud Committed Use Discount

Discount from on-demand cloud pricing via committed use agreements (1-year or 3-year reservations).

Commitment	Discount
On-demand	0%
1-year reserved	30%
3-year reserved	50%

Debt/Equity Ratio % ?

Debt/Equity Ratio (WACC)

Proportion of debt financing for build scenario. Higher debt ratio lowers WACC but increases financial risk.

Strategy	D/E Ratio
Conservative	30-40%
Balanced	50-60%
Leveraged	70-80%

Methodology & Assumptions

Build Model

CAPEX = IT Load (MW) × Regional Cost/MW × Tier Multiplier. Annual OPEX includes power (IT × PUE × 8,760h × $/kWh), staffing (headcount × salary), maintenance (3% of CAPEX), insurance (0.7% of CAPEX), network ($20K/MW/mo), and overhead (4% of OPEX). Inflation applied per-category annually.

Colo Model

Annual lease = IT Load (kW) × Wholesale Rate ($/kW/mo) × 12 months. Includes setup fees ($50K/MW), reduced staffing (1.5 FTE/MW), network connectivity ($15K/MW/mo), and 3% overhead. Annual escalation of 3% applied to lease costs. Growth rate scales capacity requirements.

Cloud Model

Annual compute = IT Load (kW) × Cloud Rate ($420/kW/mo) × 12 × (1 - discount). Adds 15% for data egress, 10% for support tier, and 2% miscellaneous. Cloud inflation at 2.5% p.a. Growth rate compounds capacity. No CAPEX or staff required.
