GPU electricity cost
One-sentence answer: Monthly $ ≈ (watts/1000) × hours/day × 30 × $/kWh using a GPU power default and a state rate from our tables.
Pick a card and a state — both dropdowns are filled from dated JSON on this site — then edit hours or override watts/$ if your meter says otherwise.
Power table as-of 2026-07-13; rates as-of 2026-07-13. Power data · Rate data
Formula
kWh/day = watts/1000 × hours · monthly $ = kWh/day × 30 × rate · yearly $ = monthly × 12
