Latency Budget Calculator
Input your services and SLO targets to get per-service latency budgets. Supports sequential and parallel service architectures.
SLO Target
Services
| Service Name | Avg Latency (ms) | Type | Actions |
|---|---|---|---|
Budget Allocation
| Service | Current Latency | Budget (ms) | Budget (%) | Status |
|---|---|---|---|---|
| API Gateway | 15ms | 26.1ms | 13.0% | Within budget |
| Auth Service | 25ms | 43.5ms | 21.7% | Within budget |
| User Service | 45ms | 78.3ms | 39.1% | Within budget |
| Database | 30ms | 52.2ms | 26.1% | Within budget |
| Total | 115ms | 200ms | 100% | OK |

How Latency Budgets Work
In a distributed system, every request passes through multiple services. A latency budget allocates a portion of your total SLO target to each service, ensuring the combined latency stays within your objective.
Sequential vs. parallel services: In a sequential architecture (A then B then C), total latency is the sum. In a parallel architecture (B and C run simultaneously after A), total latency is A + max(B, C).
