About this tool
Data Freshness SLO Calculator
The Data Freshness SLO Calculator computes SLO compliance percentage, budget remaining, and breach risk from pipeline lag and freshness SLO target.
• Check whether current pipeline lag is within freshness SLO
• Calculate freshness SLO compliance for a data quality report
• Set alert thresholds for a freshness monitoring rule
• Model freshness risk from increasing pipeline run frequency

FAQ
What does this tool tell you?
The Data Freshness SLO Calculator computes SLO compliance percentage, budget remaining, and breach risk from pipeline lag and freshness SLO target.
What affects the result most?
Data freshness SLO: max acceptable age of data in a table or metric — e.g., reports table updated within 4 hours. Freshness = current_time - max(event_time) — time since newest event landed. Freshness budget: SLO target - current_freshness = remaining budget.
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.
