Key takeaways

A powerful rig does not guarantee a profit.
Free power does not erase wear or pool fees.
Mined crypto is income when you receive it.

Short answer

Electricity is usually the largest cost in crypto mining and the one that matters most, since it comes back every month. Hardware, pool fees, cooling and taxes decide the rest of the total.

Mining adds new transaction blocks to a proof-of-work blockchain. Miners race specialized machines to solve a puzzle, and the winner earns new coins plus fees.

What hardware costs should I expect?

Mining costs at a glance

Hardware: Purchase dedicated computer hardware
Energy: Find cheap sources of energy
Rewards: Receive bitcoins as a reward

You buy the machines before you earn any crypto, so the purchase price is a major upfront cost. Hardware also ages, and older rigs lose resale value as newer models do more work per watt.

Newer versus older mining hardware
Factor	Newer hardware	Older hardware
Power efficiency	Usually better	Usually worse
Resale value	Holds longer	Falls faster
Covering costs	More likely	Less likely

What ongoing costs add up?

Electricity is usually the largest recurring cost, so many miners hunt for cheap power. Pools take a cut of your rewards, and cooling and hosting add monthly bills.

Electricity: a rig draws power you pay for monthly.
Pool fees: a pool keeps a share of the rewards you earn.
Cooling: fans and air conditioning use power in hot weather.
Hosting: rented space and power add a monthly bill.

How do network changes affect costs?

The network adjusts how hard it is to earn a block. Bitcoin's difficulty changes about every two weeks, and the block reward was cut in April 2024. More miners joining means the same hardware earns less crypto.

How does the IRS treat mining costs?

The IRS treats mined crypto as income when you receive it, and you report its dollar value on the day you get it. Business miners may be able to deduct equipment and power.

Tax records to keep

Record the date and dollar value of each reward.
Save receipts for hardware, power and pool fees.
Report mining income in the year you receive it.

Frequently asked questions

Higher rates raise your monthly bill directly, because power is usually the largest recurring cost. That can decide whether older hardware pays off.

Your power and hosting bills stay in dollars while the rewards you earn are worth less. Older, less efficient rigs are usually shut off first.
