# On-call cost calculator

Estimate what an on-call rotation costs in interrupted hours and pay, and how the load spreads.

## How it works

Every page interrupts someone. Night pages cost more than their minutes, in lost sleep and a slower next day.

```
cost = hours × rate + night hours × rate × 0.5 + pay
```

## Questions

### How many pages a week is too many?

More than a couple of actionable pages per shift leads to burnout. Fix noisy alerts first.

### How do I cut pages?

Alert on symptoms users feel, and use burn-rate alerts instead of fixed thresholds.
