What does a crypto mining rig cost to run?

Run the numbers on your own use

Change any of these and the figures update. The defaults are the typical case described above; your rate is the input that moves the answer most.

Why this is lower than the number you will see elsewhere

Almost every published answer to this question multiplies the rating on the label by the hours the appliance is switched on. For a crypto mining rig that gives 26,280 kWh a year, or $4,820.

Deliberately constant. A miner is designed to run at full load continuously, which makes it the highest-duty load in any house that has one.

The arithmetic, step by step

Nothing here is hidden, so you can check it or change it. Working in the order the formula runs:

1. 3,000 W — what it draws while it is actually drawing. This is the rating on the plate.
2. × 100% — the share of its in-service time it is really pulling that. Deliberately constant. A miner is designed to run at full load continuously, which makes it the highest-duty load in any house that has one.
   That gives 3000 W averaged across the hours it is on.
3. × 24 hours a day × 365 days — A single ASIC unit running around the clock.
   3000 × 24 × 365 ÷ 1,000 = 26,280 kWh a year.
4. × 18.34¢ — the US average residential rate for June 2026.
   26,280 kWh × 18.34¢ = $4,820 a year.

Change any assumption in the calculator above and every figure on this page moves with it. The two that matter most are your rate, which varies 4× across the country, and the hours — the duty cycle is a property of the appliance, but the hours are a property of you.

How sensitive is that number?

A single figure invites more confidence than it deserves. Here is the same appliance under assumptions either side of the default, so you can see how much of the answer is the appliance and how much is the guess about how you use it.

Everything else held at the default. The spread here is the honest error bar on the headline figure.

What it costs per hour, day and month

At 18.34¢ per kWh, the US residential average for June 2026.

The thing worth knowing

This is the only appliance on this site whose entire purpose is to convert electricity into heat as a by-product of computation, and it does so at full rate for all 8,760 hours. At the US average rate a single 3 kW unit costs more per year to run than most households spend on all their other electricity combined. It also dumps 3 kW of heat into the building, which in summer the air conditioning must then remove at further cost.

What it costs in your state

The appliance is the same everywhere; the rate is not. Running this crypto mining rig costs $13,855 a year in Hawaii and $3,445 in Nevada — a difference of 4×.
