Each tool works in two steps: enter your own figures, then read the summary and download it for the plan, the budget request or the next exercise. The formulas are stated on every page, with a worked example, the limits of the estimate and the sources behind the defaults. Everything runs in your browser; nothing you type is sent to us.
Power and equipment
- Power station runtime
How long a portable power station runs your devices, and the capacity a full day or weekend needs.
- UPS size and runtime
The watt and VA rating your desk or network closet needs, and minutes of battery at your load.
- Generator size
Running watts, the starting surge of the biggest motor and the generator rating that covers both.
Planning and recovery
- Downtime cost
Lost revenue, idle staff time and one-off recovery costs for an outage of any length.
- Emergency water and food
Gallons of water, containers and calories for a household or an office sheltering in place.
- Backup and restore time
Hours to upload a full backup and to pull it back, checked against your recovery time objective.
