ENGINEERING TOOL

SLO Error Budget Calculator

Turn an availability SLO into a concrete downtime allowance and understand how observed downtime is consuming the budget.

What this tool helps you estimate

Translate an availability target into an allowed downtime budget, then estimate consumption, burn rate and a transparent linear projection.

Service-level objectives
Availability
Downtime budget
Error-budget burn rate

The interactive calculation runs in your browser. Treat the output as an estimate, document assumptions, and validate them against service telemetry and operational evidence before making production decisions.

Read the SLO error-budget planning guide for measurement assumptions, burn-rate interpretation and operating-policy examples.
