Key points#

• In large migrations, internal resource costs account for 20 to 35% of total project cost.

• Benchmark data shows that organizations using offshore-led delivery models (with onshore leadership) achieve consulting cost savings of 35 to 55% vs.
• Big 4 equivalents, but with trade-offs in implementation timeline (typically 15 to 25% longer) and knowledge transfer quality.
• We routinely see organizations spend 2 to 3x their initial data migration budget once they understand the actual state of their master data.".
• Migration cost reduction strategies vary by organization size and complexity, but five approaches consistently produce 15 to 30% cost reductions without materially increasing delivery risk:.
• Organizations that adopt Activate with minimal configuration deviations reduce consulting costs by 20 to 35% compared to bespoke implementations.
• Most ECC environments carry 15 to 40% of custom code that hasn't been used in 24+ months.
• Benchmark data shows custom code rationalization projects of 3 to 4 months reduce migration consulting costs by $500K to $3M on mid-to-large projects.
• Organizations that negotiate fixed-price contracts for defined deliverables shift delivery risk to the SI, and typically negotiate 10 to 18% below T&M estimates for comparable scope.

Why S/4HANA Migration Costs Vary So Dramatically#

S/4HANA migration costs are notoriously difficult to estimate, and even more difficult to benchmark, because they depend on factors that vary enormously between organizations. For the full SAP pricing picture including RISE and licensing, see the SAP Pricing Benchmarks overview.

The primary cost drivers in S/4HANA migration are the complexity and age of the existing ECC landscape (custom code volume, number of interfaces, data quality), the chosen deployment model (RISE vs. on-premises vs. private cloud), the scope of the migration (new implementation, brownfield migration, or bluefield selective data transition), the choice of systems integrator (Big 4 vs. boutique SAP specialist), and the organization's internal change management capability.

Given these variables, migration cost benchmarks must be interpreted in the context of your specific situation, not treated as universal targets. Nevertheless, the benchmark ranges below, drawn from 80+ enterprise S/4HANA migrations completed between 2023 and 2025, provide a meaningful reference point for CFOs and CIOs building business cases.

Migration Complexity Categories#

Total Migration Cost Benchmarks by Organization Size#

Total cost of S/4HANA migration includes all project cost categories: systems integrator fees, internal resource cost (which is typically underestimated), SAP licensing increments, infrastructure, integration rework, data migration, testing, training, and hypercare.

These ranges reflect all-in project costs including both external and internal resource costs. Many organizations underestimate internal costs, the time their own SAP team, finance, operations, and IT staff spend on the migration project. In large migrations, internal resource costs account for 20 to 35% of total project cost.

Cost Category Benchmarks#

Understanding the breakdown of migration costs by category is essential for identifying where estimates are inflated and where budget should be protected. The following benchmarks reflect typical cost category splits across the migrations in our database:

Systems Integrator (Consulting) Fees#

SI fees are the largest single cost category in most S/4HANA migrations, typically 45 to 60% of total project spend. The choice of SI and the rate structure negotiated have the largest single impact on total migration cost.

Benchmark data shows that organizations using offshore-led delivery models (with onshore leadership) achieve consulting cost savings of 35 to 55% vs. Big 4 equivalents, but with trade-offs in implementation timeline (typically 15 to 25% longer) and knowledge transfer quality. For straightforward brownfield migrations, offshore-led delivery is well-proven. For complex transformational migrations, the trade-off is less favorable.

SAP License Increments#

Moving from ECC to S/4HANA typically requires either additional licenses or conversion from existing license types. Common license increments and their benchmark costs:

• S/4HANA license conversion from ECC perpetual: Typically 15 to 30% uplift on existing license value, subject to negotiation
• New user licenses for functionality not previously licensed: $1,500 to $4,200 per user depending on license type
• S/4HANA module licenses (new modules adopted during migration): Engine pricing, variable by module

Data Migration#

Data migration costs are consistently underestimated in SAP migration budgets. Benchmark cost ranges:

"The single biggest source of budget overruns in S/4HANA migrations is not consulting fees, it's data. We routinely see organizations spend 2 to 3x their initial data migration budget once they understand the actual state of their master data."

Get a Migration Cost Benchmark Before Approving Budget#

Our migration cost benchmarks cover 80+ S/4HANA projects by size, complexity, and deployment model. Don't approve a migration budget without external validation.

Migration Timeline Benchmarks#

Migration timeline is directly correlated to cost, longer projects consume more consulting resource, more internal management overhead, and more risk of scope creep. Benchmark timelines from our database:

How to Reduce Migration Costs Without Sacrificing Quality#

Migration cost reduction strategies vary by organization size and complexity, but five approaches consistently produce 15 to 30% cost reductions without materially increasing delivery risk:

01. SAP Activate Over Custom Methodology#

SAP's Activate methodology, built around pre-configured best-practice content, significantly reduces design and build time compared to custom-designed implementations. Organizations that adopt Activate with minimal configuration deviations reduce consulting costs by 20 to 35% compared to bespoke implementations. The resistance usually comes from business stakeholders who want to maintain existing non-standard processes, a governance challenge, not a technical one.

02. Custom Code Rationalization Before Migration#

Most ECC environments carry 15 to 40% of custom code that hasn't been used in 24+ months. Eliminating this code before migration reduces the scope of custom code remediation, the single most time-consuming and expensive part of a brownfield migration. Benchmark data shows custom code rationalization projects of 3 to 4 months reduce migration consulting costs by $500K to $3M on mid-to-large projects.

03. Fixed-Price SI Contracts#

SI proposals typically come as time-and-materials (T&M) with fixed milestones. Organizations that negotiate fixed-price contracts for defined deliverables shift delivery risk to the SI, and typically negotiate 10 to 18% below T&M estimates for comparable scope. Fixed-price contracts require tighter scope definition upfront but provide significantly better budget predictability.

04. Phased Scope Delivery#

Attempting to migrate the entire ECC landscape in a single "big bang" deployment is the highest-risk, highest-cost approach. Organizations that phase migration, core finance and procurement first, then manufacturing, then global rollout, reduce single-project risk and spread capital expenditure across multiple budget years.

05. Hyperscaler Infrastructure Negotiation#

If deploying RISE, the infrastructure component is typically the least scrutinized part of the bundle. Organizations that separately negotiate the infrastructure tier, or leverage existing hyperscaler commitments, achieve 8 to 14% savings on the infrastructure component of their RISE contract.
