Cost Comparison: RISE with SAP vs Own Infrastructure

Why This Comparison Matters

RISE with SAP is SAP's cloud-bundled subscription offering that packages S/4HANA Cloud Private Edition, Business Technology Platform (BTP) credits, Signavio process intelligence, SAP Business Network connectivity, and infrastructure operations into a single annual fee. Since its launch in 2021, SAP has aggressively pushed RISE as the default migration path for ECC customers facing the 2027 mainstream maintenance deadline.

The problem is that SAP's internal TCO models are built on assumptions that inflate the apparent cost of staying on-premises and suppress the visible cost of RISE. Organisations that accept SAP's TCO modelling without independent verification routinely overpay by hundreds of thousands to millions of euros over the contract term.

This analysis provides a framework for building your own honest TCO comparison — one that accounts for the variables SAP's proposals typically omit.

What RISE with SAP Actually Costs

RISE pricing is based on Full User Equivalents (FUEs), a metric that translates your user base into a standardised consumption unit. SAP does not publish RISE list prices, but independent benchmarks place the typical range at €900 to €2,200 per FUE per year at Standard tier, with Premium and Essentials tiers priced differently. A 1,000-FUE organisation on RISE Premium can therefore expect an annual subscription commitment in the range of €1.5M to €3M before any negotiated discounts.

The Components You Are Paying For

A RISE contract bundles several components whose individual value organisations rarely scrutinise before signing. These include S/4HANA Cloud Private Edition (the ERP core), SAP BTP credits at a capped volume, SAP Signavio Process Intelligence for process analysis, SAP Business Network connectivity for supplier transactions, and managed infrastructure operations. On the surface, bundling these together appears to represent value. In practice, the majority of RISE customers fully utilise only the ERP core — the remaining bundle components become shelfware that nonetheless drives the per-FUE cost upward.

The Hidden Costs in RISE Proposals

SAP's RISE proposals are notable not for what they include but for what they exclude. Organisations reviewing a RISE quote must independently account for the following cost categories, which are consistently absent from SAP's initial proposals.

BTP Overage Charges

Each RISE tier includes a capped allocation of BTP credits for workloads such as custom integrations, extensions, and analytics. The included credit volumes are calibrated to basic use. Organisations that deploy BTP for meaningful custom development, complex integration scenarios, or advanced analytics will exhaust their credit allocation and face consumption-based overage billing. BTP overage rates are not published and must be negotiated upfront. Failure to do so leaves organisations exposed to uncapped consumption charges that can add hundreds of thousands of euros to the annual bill.

Data Migration and Transformation Costs

RISE includes the infrastructure and subscription licence for S/4HANA Cloud Private Edition. It does not include the professional services cost to migrate from ECC to S/4HANA — a cost that typically ranges from 1x to 3x the first-year RISE subscription for complex organisations. Many organisations in RISE TCO discussions neglect to include migration costs because SAP's proposals focus on post-go-live steady-state costs. The migration investment — scoped independently of SAP — must be amortised over the full contract term to produce an honest TCO comparison.

Double-Running Legacy Systems

S/4HANA migrations take time. Most enterprise organisations running parallel legacy and new environments for 12 to 24 months during the transition period will pay both SAP ECC maintenance (typically 22 percent of on-premise licence value annually) and the RISE subscription simultaneously. This double-running cost of six to eighteen months of overlap is never surfaced in SAP's RISE proposals but is one of the largest genuine cost differentials in any honest TCO model.

Add-On Licensing Not Covered by RISE

RISE covers the S/4HANA core. A range of SAP solutions that many organisations rely on — including SAP Analytics Cloud beyond the RISE-included volume, SAP SuccessFactors, SAP Ariba beyond Business Network basics, SAP Concur, and extended SAP Industry Cloud applications — require separate licensing on top of the RISE fee. SAP's proposals typically present these as optional additions rather than likely requirements, creating a misleading picture of the total SAP landscape cost.

Exit Costs and Lock-In

RISE contracts typically require a minimum five-year commitment with no exit provisions short of paying out the remaining term. There is no meaningful portability — the S/4HANA Private Cloud instance is operated exclusively by SAP, and migrating to a different hyperscaler or bringing operations in-house mid-contract is not permitted under standard RISE terms. The effective cost of vendor lock-in, while difficult to quantify in a TCO model, must be treated as a risk premium that any sensible assessment should reflect.

What Own Infrastructure Actually Costs

The own infrastructure path — whether on-premises, co-location, or private cloud on hyperscaler infrastructure — carries its own genuine cost structure that SAP's TCO models are designed to overstate.

Infrastructure and Hardware

For organisations with existing data centre footprint and hardware refresh cycles aligned to the S/4HANA migration timeline, the marginal infrastructure cost of running S/4HANA on-premises is often lower than SAP's models assume. SAP's assumptions consistently benchmark against the cost of a net-new data centre buildout rather than the actual incremental cost of utilising existing capacity. Organisations with efficient, modern infrastructure will find SAP's infrastructure cost assumptions significantly overstated.

SAP Maintenance and Licences

On-premises S/4HANA requires perpetual licence ownership — either via new purchase or conversion from existing ECC licences — plus annual maintenance at 22 percent of net licence value. For organisations with a mature SAP estate and fully amortised licence investments, the effective per-user cost of on-premises maintenance is substantially lower than the RISE FUE-based subscription over a 7 to 10 year horizon.

Basis and Operations Staffing

SAP's TCO models assume that on-premises operation requires a full internal Basis team, including senior architects, administrators, and security specialists. In practice, most organisations of significant size already have this capability. Where genuine staffing costs exist, they are often partially offset by the systems integration and third-party consulting costs embedded in RISE that SAP does not surface separately. Cloud managed services from partners can further bridge operational capability gaps without requiring the full internal staffing that SAP's models assume.

The TCO Crossover Point

The central finding from independent TCO analysis across hundreds of SAP engagements is that the crossover point — the year at which RISE cumulative cost exceeds the own-infrastructure cumulative cost — typically falls between year five and year seven for organisations with mature SAP estates.

Over a three-year horizon, RISE often appears cheaper because it defers capital expenditure and eliminates the Year 1 hardware and licence costs associated with a new S/4HANA deployment. Over a five-year horizon, the costs converge. Beyond seven years, own-infrastructure consistently outperforms RISE on a pure cost basis for organisations with efficient operations.

The crossover calculation is highly sensitive to four variables: the organisation's existing infrastructure investment (already depreciated assets favour own-infrastructure), the Basis team cost (SAP overstates this for most organisations), BTP utilisation (heavy BTP users see RISE cost escalate faster), and the negotiated RISE discount (a poorly negotiated RISE contract accelerates the crossover point).

Where RISE Genuinely Wins

There are genuine scenarios where RISE with SAP delivers better value than own infrastructure, and intellectual honesty requires acknowledging them.

Organisations without existing SAP infrastructure — a greenfield S/4HANA deployment or a carve-out entity — face the full capital cost of building a new on-premises footprint. In this scenario, RISE's deferred CapEx model is genuinely advantageous over a three to five year horizon.

Organisations with limited internal Basis capability and no appetite to build it will find the managed operations component of RISE genuinely valuable. The total cost of external managed services to run an on-premises S/4HANA environment can in these cases match or exceed the RISE infrastructure component.

Where SAP's BTP platform represents a strategic investment — organisations planning significant custom development, AI extensions, and integration on BTP — RISE's included BTP credits can represent meaningful value, particularly if the credit allocation is negotiated upward as part of the commercial discussion.

Negotiation Levers Before You Sign

RISE is a negotiated contract, not a standard price list. Organisations that treat it as a catalogue purchase consistently overpay. The following levers are available in every RISE negotiation.

FUE Count Verification

SAP's initial FUE calculation is almost always inflated relative to your actual active user base. Independent FUE verification before entering negotiations routinely produces a 15 to 25 percent reduction in the baseline FUE count, directly reducing the annual subscription cost. SAP's FUE methodology counts historical licence assignments rather than current active users — a distinction that produces very different results in mature SAP estates.

BTP Credit Allocation

The BTP credit volume included in RISE Standard and Premium tiers is insufficient for organisations with meaningful integration or extension requirements. BTP credit uplift must be negotiated into the commercial terms, not as a post-contract add-on at consumption rates. Securing 2x to 3x the standard BTP credit allocation at the point of contract signature is achievable in competitive RISE negotiations.

Price Escalators and Term Flexibility

SAP's standard RISE contracts include annual price escalators of 3 to 5 percent. Capping escalators at CPI or at a fixed 2 percent over the contract term reduces the compounding cost of a five-year commitment significantly. Where possible, securing a right to reduce the FUE count in year three of the contract — a ratchet-down provision — provides meaningful flexibility that SAP will resist but cannot categorically refuse for large deals.

Migration and Transition Support

SAP Access and RISE negotiating teams have discretionary budget for migration support credits, implementation partner discounts, and BTP accelerator packages. These concessions are available but must be requested explicitly as part of the commercial negotiation, not as afterthoughts. Organisations that engage SAP in an advisory-led commercial discussion — rather than a features discussion — consistently extract more implementation support value from the RISE negotiation.

Building Your Own TCO Model

An honest RISE vs own-infrastructure TCO model requires a ten-year horizon, not five. It must include all of the cost categories that SAP's proposals omit: BTP overages at realistic consumption projections, double-running costs during migration, migration professional services (not just SAP's, but all system integrator costs), add-on licensing for the full SAP landscape, and the exit cost premium associated with five-year lock-in. Against this complete picture, own infrastructure should be modelled at actual incremental cost — using existing infrastructure rather than greenfield assumptions — and at realistic Basis staffing levels rather than SAP's overstated benchmarks.

The organisations that make well-informed RISE decisions are those that invest in an independent TCO analysis before engaging SAP commercially. The cost of that analysis is trivially small relative to the contract value at stake in any enterprise RISE engagement.
