Inputs

Provider
Monthly on-demand spend$200,000
Total monthly cloud spend (compute focus — commitments don’t apply to all line items).
Steady-state %75%
Portion of spend that runs 24×7 across a year. The honest baseline to commit against.
Commitment coverage of steady-state80%
FinOps Foundation target: 70-90%. Lower = under-covered. Higher = lock-in risk.
1-year share of commitments60%
Rest is 3-year. 1-year discount < 3-year. 3-year lock-in is the trade-off.
All-Upfront share (vs No-Upfront)20%
All-Upfront: best discount, full cash now. No-Upfront: smaller discount, monthly payment.
Expected growth (next 12 months)20%
Net spend growth (after rightsizing). Negative = divestiture / efficiency win.

How the calculation works

Committed spend = monthly × steady-state% × coverage%. Effective discount is a weighted blend of 1y vs 3y and No-Upfront vs All-Upfront discount rates per provider (compute-class). On-demand portion is billed at full price; commitment portion at on-demand × (1−blended discount).

Lock-in risk rises with coverage and 3-year share. Breakeven utilisation = (commitment hourly cost) / (on-demand hourly cost) — below this, commitment loses money. Growth pulls coverage % down over time; the optimiser flags when re-rebalancing is overdue.

Discount rates are illustrative class averages from published 2026-05 documentation. Real-world rates vary by region, instance family, and account size. Use for shape and trade-off comparison, not for procurement commitment sizing — use your provider’s recommendations API for that.
