Mining Power Cost Calculator

It depends entirely on the miner. A Bitaxe Supra uses about 15W, which translates to roughly 10.8 kWh per month — less than a single LED light bulb running 24/7. An Antminer S19 uses 3,250W, consuming about 2,340 kWh per month — roughly equivalent to an average Canadian household’s total electricity consumption. Use the calculator above to model your exact setup. The key is matching your miner’s power draw to your electrical capacity and budget.

Quebec offers the lowest residential electricity rates in Canada at approximately $0.06/kWh through Hydro-Québec, followed by Manitoba at $0.09/kWh and British Columbia at $0.10/kWh. These provinces benefit from abundant hydroelectric power. Quebec miners pay roughly one-third of what Alberta or PEI miners pay. This is why D-Central’s hosting facility is located in Laval, Quebec. For home miners, your province’s rate is one of the most important variables in your profitability equation.

Small miners like the Bitaxe (5–80W) or NerdMiner (1W) can run on any standard 120V outlet — they draw less power than a laptop charger. Mid-range miners like the Antminer S9 (1,350W) can work on a dedicated 15A/120V circuit but will draw over 11 amps, leaving little headroom. Large miners like the S19 (3,250W) or S21 (3,500W) require a dedicated 240V circuit and a 20A or 30A breaker. The calculator above shows your amperage draw and recommended breaker size for both 120V and 240V. Always consult a licensed electrician for circuit installations.

Yes, and the physics is simple: electric heaters convert 100% of electricity to heat. Bitcoin miners also convert 100% of electricity to heat — they just do useful computation along the way. If you would have run a 1,500W space heater anyway, replacing it with a 1,500W miner means your heating cost is zero because you would have spent that electricity regardless, but now you are also earning Bitcoin. In Canada, where heating is needed roughly 6-8 months per year, this offset can cut your effective mining cost in half on an annual basis. D-Central’s Bitcoin Space Heaters are purpose-built for this use case.

Power cost is one half of the equation — the other half is mining revenue, which depends on your hashrate, network difficulty, and Bitcoin price. This calculator gives you the cost side. For a complete profitability picture, pair your results here with our Mining Profitability Calculator which factors in hashrate, difficulty, pool fees, and current BTC price. As a general rule, at current difficulty levels, you need below $0.10/kWh for older miners (S9/S17) to be profitable, while newer efficient machines (S21) can remain profitable up to $0.15-0.18/kWh. Solo mining with Bitaxe is a different calculation entirely — it is lottery mining where a single block find pays 3.125 BTC.
