SLO / Error Budget Calculator
Convert uptime targets into downtime budgets, burn rates, and review thresholds.
What does this reliability target allow in practice, and when should releases or riskier changes stop?
How to use it
- Set the assumptions on the left until they match the workload you are reviewing.
- Validate the structured result, metrics, and recommendations before exporting.
- Copy or export the artifact directly into the design doc, ticket, runbook, or review packet.
What you leave with
- Downtime budget, daily budget, and bad-request budget.
- A 50% burn checkpoint for release and incident policy.
- A plain-language output that works in SRE reviews and service scorecards.
Tool inputs
SLO / Error Budget Calculator
Translate reliability targets into downtime budgets, failing request budgets, and burn checkpoints.
Shortcut keys: Ctrl/Cmd + Shift + C copies the current output, and Ctrl/Cmd + Shift + S saves a revision snapshot.
Result
SLO error budget
A 99.9% SLO over 30 days allows 43.2 minutes of downtime and 7,500 failing requests.
Downtime budget
43.2 min
Total downtime allowed across the evaluation window.
Daily budget
1.44 min
Average daily downtime allowance at this SLO.
Bad requests
7,500
Failing-request budget available before the SLO is missed.

Error-budget policy
SLO target: 99.9% Evaluation window: 30 days Downtime budget: 43.2 minutes Average daily downtime budget: 1.44 minutes Bad request budget: 7,500 requests 50% burn warning threshold: 21.6 minutes Suggested operating policy: - Freeze risky releases once 50% of budget is consumed - Require incident review before exceeding 75% burn - Reset release cadence only after burn rate stabilizes
FAQ
Questions teams ask before they adopt this workflow.
When should teams use SLO / Error Budget Calculator?
This tool is most useful when the team needs a fast, reviewable answer before moving into a larger design, documentation, or governance workflow.
Who usually benefits most from SLO / Error Budget Calculator?
Architects, platform teams, and technical leads get the most value because they need a clear artifact they can copy into reviews, runbooks, tickets, and stakeholder updates.
How does SLO / Error Budget Calculator connect back to Architecto?
The free surface reduces friction. Once the team needs richer diagrams, review automation, or documentation outputs, the matching Architecto feature takes over without changing the workflow language.
