build.api-latency-budget Calculator
Allocates an end-to-end API latency budget across authentication, database, business logic, serialisation, and network, showing headroom remaining. If auth + DB alone consume the full p99 budget, the service can never meet SLA — this makes the constraint visible.
Inputs
Slo Ms
Reference formula or conversion factor shown for context.
Network Ms
Energy transferred by a force over a displacement (J = N·m).
Db Ms
Reference formula or conversion factor shown for context.
Cache Ms
Reference formula or conversion factor shown for context.
Results
infra budget
Sample size or count used in the calculation.
app logic budget
Reference formula or conversion factor shown for context.
p99 estimate
99th percentile latency -- only 1% of requests are slower. Captures tail latency that affects the worst-case user experience.
headroom
Buffer between current performance and a limit or target. Positive headroom is safety margin; zero or negative headroom means the limit has been hit.
