Carve out IT separation costs run 1.4 to 3.2 percent of carve out annual revenue across a 24 to 36 month program, with TSA overhead adding another 9 to 18 percent during the 12 to 24 month transition services period. Across our 124 carve out program panel from 2022 to 2025, the steady state run rate sits 0.4 to 1.1 percent above pro forma cost as the carve out absorbs platform costs that the parent previously spread across a larger denominator. The carve out IT cost is the largest controllable cost component of a divestiture transaction outside the deal price, and the structure of the Tier 1 software contracts at signing is the single largest input to that cost.
Methodology notes: anonymized enterprise carve out programs analyzed Q1 2022 through Q4 2025. Sample weighted toward North America (58 percent), EMEA (29 percent), APAC (13 percent). Carve out revenue ranged from 80 million USD to 4.2 billion USD. Costs reported as percentage of carve out annual revenue, normalized for industry mix. Sample concentrated in IT intensive sectors (financial services, technology, healthcare).
What carve out IT cost actually includes
Carve out IT cost has three components. The first is the one time separation project cost: program management, application separation engineering, data extraction, user enablement, security separation, identity provider stand up, third party contract assignment or replacement. The second is the TSA overhead: the markup that the parent charges the carve out for IT services during the transition services period, plus the carve out's own program cost to consume the TSA and plan exit. The third is the steady state run rate delta: the gap between the carve out's pro forma cost as a small standalone IT shop and what its share of the parent's costs looked like before separation.
The three components have different drivers. The one time cost is driven by application complexity and Tier 1 software contract structure. The TSA overhead is driven by parent TSA pricing policy and TSA period length. The run rate delta is driven by carve out scale, the parent's ability to negotiate transferable Tier 1 contracts, and the carve out's ability to land discounted standalone deals with the same Tier 1 vendors. Each component is benchmarked separately on the 124 panel because the optimization moves for each are different.
The three component benchmark
| Component | Median | Top Quartile (Lower Cost) | Bottom Quartile |
|---|---|---|---|
| One time separation cost | 1.4-3.2% of carve out revenue | 0.8-1.6% | 3.5-6.4% |
| TSA overhead per year | 9-18% above arms length pricing | 4-9% | 22-38% |
| Steady state run rate delta | +0.4 to +1.1% versus pro forma | -0.2 to +0.4% | +1.8 to +3.4% |
Methodology: 124 carve out programs across mixed industries. Top quartile defined as the lower cost quartile in each component. Bottom quartile defined as the higher cost quartile. Steady state run rate measured at TSA exit plus 12 months.

One time separation cost drivers
The one time cost is driven by three factors. Factor one is application complexity: how many applications need to be separated, what share are SaaS versus on premise, how much data extraction is required. Factor two is Tier 1 software contract structure at signing: whether the deal terms allow contract assignment, whether the carve out can land a standalone deal at the parent's discount tier, whether the parent has consent rights. Factor three is the timeline: a 12 month forced separation costs 30 to 60 percent more than a 24 month separation because parallel application separation produces less risk averse design.
Application complexity bands
| Application Footprint | Median One Time Cost | Typical Timeline |
|---|---|---|
| Light (under 80 applications, 70%+ SaaS) | 0.8-1.6% of revenue | 12-18 months |
| Standard (80-200 applications, mixed) | 1.4-2.8% of revenue | 18-30 months |
| Heavy (200-500 applications, on prem heavy) | 2.4-4.2% of revenue | 24-36 months |
| Complex (500+ applications, regulated industry) | 3.6-6.4% of revenue | 30-48 months |
Tier 1 software contract mechanics
The Tier 1 software contracts are the single largest variable. Each major vendor has a different posture toward carve outs. Microsoft EA contracts typically permit divestiture assignment with parent and divesting entity execution of an amendment, but the carve out usually falls to a smaller volume tier on standalone, raising unit pricing 8 to 18 percent. Oracle ULA carve outs require either a formal ULA certification at the time of carve out, with the divesting entity receiving a defined share of the certified count, or an Oracle approved ULA split that often increases combined fees by 12 to 24 percent. SAP enterprise agreements require document tier and digital access recalculation at separation, with the carve out typically receiving a higher per document price.
Salesforce ELA carve outs require ELA scope segmentation, with the carve out receiving a smaller volume tier and typically losing 10 to 18 percent of the parent's discount. ServiceNow tiered subscription packs split based on user and workflow counts, with the carve out receiving a smaller pack pricing tier. Workday subscription unit pricing splits cleanly because the unit definitions are user based, but the carve out loses the parent's negotiated discount tier and typically prices 12 to 22 percent higher per unit. AWS EDP commitments and Google Cloud CUDs do not transfer cleanly; the carve out typically runs on pay as you go during the TSA period and negotiates its own commit at TSA exit. See the Microsoft pricing profile, the Oracle pricing profile, the SAP pricing profile, the Salesforce pricing profile, and the ServiceNow pricing profile.

TSA overhead benchmark
TSA overhead is the second cost component. The parent charges the carve out for IT services during the transition services period. The pricing model is set in the TSA, typically a cost plus formula with a markup. The 124 panel shows that the median TSA markup is 9 to 18 percent above arms length pricing for the same services. Top quartile programs negotiate the markup to 4 to 9 percent. Bottom quartile programs accept markups of 22 to 38 percent, often because the TSA was drafted as a deal closing afterthought rather than as a substantive commercial document.
The TSA period itself is the larger lever. A 12 month TSA at 12 percent markup costs less than a 24 month TSA at 6 percent markup if all other things are equal. Top quartile programs invest heavily in TSA exit acceleration: standing up the carve out's own IT operations as fast as possible to compress the TSA period. The median TSA period is 12 to 24 months. Top quartile is 9 to 14 months. Bottom quartile is 30 to 48 months. The cost difference between top and bottom quartile, at typical TSA markups, is 12 to 28 percent of carve out annual revenue cumulatively, which is often the single largest line on the carve out transaction P&L.
TSA scope decisions
The TSA scope decision matters as much as the markup. Top quartile programs scope the TSA narrowly: only the services the carve out cannot reasonably stand up in 90 days. Standard TSA scope items are payroll continuity, ERP support continuity, identity provider continuity, network connectivity, and customer facing application continuity. Items that the carve out can stand up quickly (productivity SaaS, collaboration tools, sales tooling) should be excluded from the TSA from day one, with the carve out's IT team responsible for direct procurement. The narrow scope approach reduces TSA overhead by 30 to 60 percent versus the broad scope default.
Steady state run rate delta
The steady state run rate delta is the gap between the carve out's standalone IT cost and what its share of the parent's IT cost was before separation. The 124 panel shows that the median delta is +0.4 to +1.1 percent of revenue: the carve out's IT runs 0.4 to 1.1 percent of revenue more expensive than its share before separation. Top quartile programs achieve a -0.2 to +0.4 percent delta, sometimes producing a steady state below pro forma. Bottom quartile programs land at +1.8 to +3.4 percent.
The delta is driven by three things. First, scale: the carve out loses the parent's volume discounts on Tier 1 vendors and pays unit prices 8 to 22 percent higher. Second, fixed cost absorption: services that were spread across a larger denominator at the parent are now spread across a smaller denominator at the carve out, raising the per revenue ratio. Third, integration cost retirement: the parent's shared services overhead disappears, which sometimes offsets the scale loss. Top quartile programs optimize the first two by negotiating standalone deals with Tier 1 vendors early in the carve out cycle, before the TSA exit deadline removes leverage.
The carve out timeline
| Phase | Timeline | Key Activities |
|---|---|---|
| 1. Diligence and Day 1 readiness | Pre signing to Day 1 | IT diligence; Day 1 readiness; TSA scope and pricing negotiation |
| 2. TSA stand up | Day 1 to Month 3 | TSA services operating; carve out IT org stood up; vendor contracts identified |
| 3. Application separation | Month 3 to Month 18 | Application separation, data extraction, Tier 1 vendor renegotiation |
| 4. TSA exit | Month 12 to Month 24 | Service by service TSA exit, carve out fully operational |
| 5. Steady state optimization | Month 24 to Month 36 | Cost optimization, vendor portfolio rationalization, run rate target achievement |
Pre signing diligence benchmark
The pre signing IT diligence determines whether the carve out IT cost benchmark is achievable. The 124 panel shows that programs with rigorous pre signing diligence land at top quartile cost 64 percent of the time. Programs with light pre signing diligence land at bottom quartile cost 51 percent of the time. The diligence is high leverage and inexpensive relative to the carve out cost.
The diligence covers four areas. Application inventory and complexity scoring (full footprint including shadow IT). Tier 1 contract review with explicit consent and assignment analysis. TSA scope draft with markup target ranges. Carve out IT org design with named leadership and target run rate. Programs that complete all four areas before signing land top quartile materially more often than programs that complete one or two areas.

The relationship to integration cost
The carve out IT cost benchmark is the divesting entity side of the equation. The buyer side runs an IT integration program, which has its own benchmark: see the M&A IT integration cost benchmark. The two programs typically run in parallel for transactions where the carve out is being absorbed into a strategic acquirer. The combined cost (carve out separation plus buyer integration) often exceeds the carve out IT cost alone by 60 to 120 percent, and the optimization moves on the two sides are different: the carve out optimizes around TSA exit speed and standalone vendor deals, the buyer optimizes around platform absorption and contract consolidation.
Common mistakes in carve out IT
Mistake 1: TSA drafted as deal close afterthought
The TSA is often drafted in the last weeks before signing without the carve out IT leader involved. The result is broad scope, high markup, and no exit accelerators. Mature programs assign a dedicated TSA negotiator from the carve out side, starting 60 to 120 days before signing, with clear authority to push back on scope and markup.
Mistake 2: Tier 1 vendor renegotiation deferred
Carve outs often defer Tier 1 vendor renegotiation until TSA exit is imminent, which removes leverage. The vendor knows that the TSA exit clock is running and that the carve out has no time to develop alternatives. Mature programs open Tier 1 vendor renegotiation in months 3 to 6 of the carve out, while the TSA is still operating, to maintain leverage.
Mistake 3: Underestimating data extraction cost
Data extraction from the parent's environments is consistently underestimated by 40 to 80 percent in initial business cases. The cost compounds when the parent's environment uses proprietary or heavily customized configurations. Mature programs include a 50 percent contingency on data extraction in the initial business case.
Mistake 4: No carve out IT leadership at signing
Programs that name the carve out CIO or head of IT only after signing lose 3 to 6 months of TSA negotiation and Tier 1 vendor renegotiation leverage. Mature programs identify the carve out IT leader before signing, ideally with the leader involved in the IT diligence.
How the carve out benchmark connects to broader M&A IT work
The carve out IT cost is one of three M&A IT benchmark categories: see the M&A IT integration cost benchmark for the buyer side, and the private equity PortCo vendor benchmark playbook for PE specific dynamics. The negotiation framework that drives Tier 1 vendor renegotiation during a carve out is the renewal negotiation playbook. The renewal calendar that operationalizes the TSA exit cadence is the renewal calendar template. The vendor consolidation play that the carve out runs once standalone is vendor consolidation playbook. The IT sourcing team design for a newly standalone carve out is IT sourcing team org design. The savings tracking methodology that audits the carve out IT cost outcome is IT sourcing savings tracking.

Frequently asked questions
What is a carve out IT cost?
The total cost to separate a divesting business unit's IT from the parent, including one time separation project cost, TSA overhead during the separation period, and the run rate cost delta versus the carve out's pro forma cost as a shared service consumer of the parent.
What is the typical carve out IT cost benchmark?
One time separation cost runs 1.4 to 3.2 percent of carve out annual revenue across 24 to 36 months. TSA overhead adds 9 to 18 percent during the TSA period, typically 12 to 24 months. Steady state run rate is usually 0.4 to 1.1 percent above pro forma cost.
How long does a carve out separation take?
Median TSA period is 12 to 24 months. Top quartile programs exit TSA in 9 to 14 months. Bottom quartile programs run TSAs 30 to 48 months. Variance comes from carve out size, application footprint, data extraction difficulty, and Tier 1 software contract structure.
How are Tier 1 software contracts handled in a carve out?
Microsoft EAs typically permit divestiture assignment via amendment but the carve out falls to a smaller volume tier. Oracle ULAs require ULA certification or split. SAP requires document tier and digital access recalculation. Salesforce ELAs require scope segmentation. ServiceNow and Workday split user based. AWS EDP and Google Cloud CUDs do not transfer; the carve out runs on pay as you go during TSA and negotiates standalone at TSA exit.
