Understand the cost and capacity of your everyday technology.

PC electricity cost: active, idle and sleep

Compare the cost of your measured active, idle and sleep power. Test the saving from replacing idle time with sleep. The example values are assumptions, not hardware benchmarks.

Download and upload time calculator

Estimate a file transfer in either direction. Use upload speed for backups. Compare current throughput with twice that speed; enter 100% when your speed already measures actual file throughput.

Streaming data and allowance calculator

Plan usage from an assumed average bitrate and your own allowance. Include game downloads or updates separately. This is not a provider billing meter or a prediction of adaptive streaming quality.

Can a lower-power PC pay for itself in electricity savings?

Compare a 60 W and 20 W computer over different daily schedules. Calculate the electricity saving, upgrade payback and the limits of this comparison.
