Cloud & RISE

Perpetual vs RISE — TCO & FUE calculator

Enter your own numbers. The tool computes the real-usage FUE requirement and compares On-Prem (maintenance) with RISE (subscription) total cost — an independent baseline against SAP's sales estimate.

Inputs

Advanced ×1
Core ×1/5
Self ×1/30
This is the input that matters most — and the one number you can't guess. Only usage analysis (t-codes + activity) reveals your users' real Advanced/Core/Self-Service split. The values here are assumptions; the result moves entirely with them.

Ctrl-Cost value: total gained over 5 years by negotiating RISE with real FUE instead of a naive estimate.

☝ This number depends on the mix you entered being right — and the mix is the hardest part to guess. Until yours is measured it stays an assumption; a precise, audit-defensible FUE base needs an analysis of your own data.

Assumptions: FUE weights follow SAP's published conversion (Advanced 1 · Core 1/5 · Self-Service 1/30). Prices are illustrative list-level; real RISE pricing is confidential/negotiated — set to your quote. On-Prem TCO treats the current perpetual license as a sunk cost (annual maintenance × term); RISE bundles infrastructure + maintenance. A negotiation starting point, not a formal quote.

This is an estimate. See the real one from your data.

The usage split that drives the result is an assumption. Ctrl-Cost measures it from your real SAP usage and turns your FUE base into an evidence-backed, audit-defensible number — the first analysis is free.
