Undervolt savings: the electricity math

First prove stability. Then price the watt delta.

Order of operations

Stress test the undervolt. Note average GPU watts before/after in the same title and settings. Only then multiply by hours and rate.

What the tool assumes

You supply ΔW, hours, and $/kWh. It does not claim undervolt is free performance.

General information, not personalized advice.

FAQ

Does undervolt always save money?

Only if it is stable and actually reduces average watts in your games.

How do I estimate dollars?

ΔW/1000 × hours/day × 365 × $/kWh.

Will performance drop?

Sometimes. Validate FPS and frame times; this site does not auto-measure them.

Is the tool a benchmark?

No. It is a cost sketch after you already know ΔW.

Advice?

Educational.
