## Formula

Incident cost = Duration × Revenue lost per hour + Duration × Responders × Responder hourly cost + Other direct costs

- Incident cost = Duration × Revenue lost per hour + Duration × Responders × Responder hourly cost + Other direct costs.
- Inputs used: Currency, Length of the incident, Revenue lost per hour of impact, People responding (optional), Cost per responder hour, Other direct costs (optional), Price as of (optional), Price source (optional).
- Edge handling: Length of the incident is required.; Length of the incident cannot be negative.; Length of the incident must be no more than 1000000000000.; Revenue lost per hour of impact is required.; Revenue lost per hour of impact cannot be negative..

## Inputs

- Currency
- Length of the incident
- Revenue lost per hour of impact
- People responding (optional)
- Cost per responder hour
- Other direct costs (optional)
- Price as of (optional)
- Price source (optional)

## Worked example: A 3.5-hour incident with six responders

Only the components you enter are counted; nothing is estimated for you.
1. Start with Currency: USD, Length of the incident: 3.5, Revenue lost per hour of impact: 4200, People responding (optional): 6, Cost per responder hour: 95, Other direct costs (optional): 0.
2. Apply the method: Incident cost = Duration × Revenue lost per hour + Duration × Responders × Responder hourly cost + Other direct costs.
3. Only the components you enter are counted; nothing is estimated for you.

## Common questions

### Where does this formula come from?

FinOps Framework capability: unit economics — cost per business unit is total cost for a period divided by the units delivered in the same period; shared cost is attributed in proportion to an agreed allocation driver. See the source link on this page.

### What kind of calculation is this?

An explicit component model: each component is entered by the user and excluded when left at zero. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Arithmetic over the figures entered — it cannot tell whether the underlying monitoring, incident records or change records are complete. A mean over a short period, or over few events, is a weak description of behaviour. The result is only as current as the rates entered; a rate taken months ago is not a current cost. Counts only the components entered; indirect effects such as churn or reputation are not modelled.

### How do I use the Incident Cost Calculator?

Enter the required values for Currency, Length of the incident, Revenue lost per hour of impact, People responding (optional), Cost per responder hour, and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Incident Cost Calculator use?

Incident cost = Duration × Revenue lost per hour + Duration × Responders × Responder hourly cost + Other direct costs The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### Can the Incident Cost Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this incident cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
