Estimate the cost of moving from SAP ECC to S/4HANA on RISE or on premise. The license bridge, the one off conversion, and the buyer side moves.
Converting from ECC to S/4HANA is a license event, not just a technical migration. The cost depends on the pathway, the user mix that converts to FUE, and whether SAP can anchor you into a RISE subscription on its terms.
Estimate the band first, then negotiate the bridge.
S/4HANA conversion cost estimator
SAP credits existing ECC entitlement toward S/4HANA, but the conversion rules favor SAP. The bridge is where the first quote inflates.
RISE bundles infrastructure and S/4HANA Cloud into a per FUE subscription. On premise keeps perpetual licensing plus maintenance. The pathway changes the cost shape entirely.
The named user base converts into the FUE metric. A clean reclassification before conversion is the largest single lever on the final number.
| Pathway | Cost shape | Where it inflates |
|---|---|---|
| RISE with SAP | Per FUE subscription bundle | Committed FUE above real use |
| On premise S/4HANA | Conversion license plus maintenance | The license bridge credit |
The standard advice is that RISE is the simple path and the conversion credit is fixed, so the move is mostly a technical project. We disagree. The conversion is a commercial reset, and SAP uses it to move buyers onto a subscription with fewer levers. The buyer side move is to model both pathways on a reclassified user base, price the RISE commit against real use, and treat the conversion as the negotiation it is.
The SAP number is rarely about the rate. It is about the user classification and the document count behind indirect access. Fix the baseline first, then negotiate.
It depends on the pathway and the user mix. The estimator gives a directional band for RISE and on premise. The largest variables are the FUE conversion of your user base and, for RISE, the committed FUE count.
Not automatically. RISE bundles infrastructure and services into a subscription that can simplify operations but removes some negotiation levers. On premise keeps perpetual licensing. Model both on a reclassified user base.
The license bridge is how SAP credits your existing ECC entitlement toward S/4HANA. The conversion rules favor SAP, so the bridge is where the first quote tends to inflate.
Twelve to eighteen months before the move. The reclassification and the pathway modeling take time, and they are the levers, so a late start forfeits them.
No. It is a directional planning band. Your contract terms and SAP's conversion rules set the real number. Use it to anchor, not to sign.
Yes. It is free and runs in your browser. No payment and no account required.
No. It is buyer side data. Build the position internally and negotiate on your modeled band.
We model both pathways on a reclassified user base, benchmark the bridge against our deal database, and sit at the table during the conversion negotiation. We are not an SAP partner.
Tool output is the anchor. Walk into the SAP meeting with a number you trust and the negotiation reshapes itself.
