# Downtime cost calculator

Estimate the revenue lost and team time spent during an outage, and what each minute costs.

## How it works

Revenue per minute is annual online revenue spread over the year, times the share that stops during the outage. Team time adds the people pulled into the response.

```
cost = revenue per minute × share affected × minutes + people × hourly cost × hours
```

## Questions

### Is this the full cost?

No. Lost trust, churn, SLA credits and delayed work come on top, and are harder to measure.

### What share of revenue is affected?

Use 100% for a full outage and less when only some pages, regions or payment methods break.
