About this tool
Platform SLO Calculator
The Platform SLO Calculator computes SLO compliance, error budget, and developer impact from platform service availability and developer user count.
• Calculate developer impact from a CI/CD service availability drop
• Assess whether current platform availability meets a 99.9% SLO target
• Compute blocked developer hours from a platform incident for a post-mortem
• Set error budget for a platform service before configuring burn rate alerts

FAQ
What does this tool tell you?
The Platform SLO Calculator computes SLO compliance, error budget, and developer impact from platform service availability and developer user count.
What affects the result most?
Platform SLOs: internal product SLOs for developer-facing services — CI/CD, scaffolding, secrets, artifact registry. Platform availability SLO: if CI/CD is down 0.1% of time = 7.3 hours/year — directly blocks developer work. Cascading impact: CI failure × developer_count × avg_blocked_time = total impact per incident.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
