## Formula

SLA cost = Covered hours × People on duty × Loaded rate + Standby hours × Standby rate + Tooling; Cost per covered hour = SLA cost ÷ Covered hours

- SLA cost = Covered hours × People on duty × Loaded rate + Standby hours × Standby rate + Tooling; Cost per covered hour = SLA cost ÷ Covered hours.
- Inputs used: Currency, Covered hours each month, People on duty during covered hours, Loaded cost per staffed hour, Standby hours each month, Standby pay per hour, Monthly monitoring and tooling cost (optional).
- Edge handling: Covered hours each month is required.; Covered hours each month cannot be negative.; Covered hours each month must be no more than 1000000.; People on duty during covered hours is required.; People on duty during covered hours cannot be negative..

## Inputs

- Currency
- Covered hours each month
- People on duty during covered hours
- Loaded cost per staffed hour
- Standby hours each month
- Standby pay per hour
- Monthly monitoring and tooling cost (optional)

## Worked example: 24/7 cover with one person on duty

Standby is counted only when you enter standby hours and pay.
1. Start with Currency: USD, Covered hours each month: 730, People on duty during covered hours: 1, Loaded cost per staffed hour: 70, Standby hours each month: 160, Standby pay per hour: 12.
2. Apply the method: SLA cost = Covered hours × People on duty × Loaded rate + Standby hours × Standby rate + Tooling; Cost per covered hour = SLA cost ÷ Covered hours.
3. Standby is counted only when you enter standby hours and pay.
