To calculate Dogecoin mining electricity cost, multiply a Scrypt ASIC’s wall power in kilowatts by its operating hours and your electricity price per kWh. For example, the 3,360 W Antminer L9 configuration discussed below uses 3.36 kW × 24 h = 80.64 kWh per day at continuous rated operation. Multiply 80.64 by your price per kWh to estimate its daily electricity cost. In LTC/DOGE merged mining, that electricity supports both coins’ rewards, so compare the cost with their combined reward value, plus any other credited merged-mining rewards.

Why a Dogecoin Electricity Calculation Is a Scrypt ASIC Calculation

Dogecoin uses the Scrypt proof-of-work algorithm, the same algorithm used by Litecoin. Dogecoin's own mining guide states that modern, profitable Dogecoin mining is generally performed with Scrypt ASICs through mining pools, and that Dogecoin supports merged mining with Litecoin and other Scrypt-based chains, meaning the same proof-of-work can be submitted for more than one chain at once (Dogecoin, "Mining Dogecoin"). In practice, this means a miner's electricity bill is not a DOGE-specific cost. It is the operating cost of a Scrypt ASIC that may simultaneously earn Litecoin block rewards and Dogecoin merged-mining rewards under a pool's accounting rules. Any electricity-cost discussion for Dogecoin should therefore start from the hardware's power draw, not from an assumption that all consumed electricity can be attributed to DOGE alone.

Calculating the Electricity Cost of a Scrypt ASIC

The base calculation for any ASIC's electricity cost is straightforward:

Electricity cost = Wall power (kW) x Operating hours x Electricity price ($/kWh)

Wall power is the electrical power drawn at the miner’s AC input, including losses in its own power supply. A manufacturer’s specification gives a typical value under stated conditions; a meter at that input measures actual consumption. As an example, Bitmain lists the Antminer L9 as a Scrypt miner suitable for LTC and DOGE mining, with a typical hashrate of 16 GH/s, typical wall power of 3,360 W, and a resulting efficiency of 210 J/GH at 25°C (Bitmain, Antminer L9 Specifications). Bitmain notes that actual hashrate can vary by roughly ±3% and wall power or efficiency by roughly ±5%, so these are manufacturer-typical figures rather than guaranteed values for every unit.

At 3,360 W of continuous operation, one L9 consumes 3.36 kW x 24 h = 80.64 kWh per day. Applying different electricity prices to this fixed energy figure illustrates how much the same hardware can cost to run depending on the tariff.

These sector averages come from the U.S. Energy Information Administration's Electric Power Monthly report (EIA, Table 5.3) and are national averages, not mining-specific tariffs. A residential rate is rarely representative of a dedicated mining operation, and an industrial average should not be treated as a rate that is automatically available to any given site; actual hosting or utility contracts vary by region, load size and agreement terms.

From Equipment Wall Power to Site-Level Electricity Cost

The calculation above is useful for a single-unit estimate, but it is not a substitute for metered, site-level electricity accounting. For an operating facility, the more reliable approach is:

Effective electricity rate ($/kWh) = Total electricity charges for the period / Metered kWh for the same period
Site electricity cost = Metered kWh x Effective electricity rate

Total electricity charges may include energy charges, demand charges, transmission or delivery charges, and applicable taxes. Dividing those charges by the same period’s metered kWh gives an effective electricity rate that includes charges not billed solely by energy use. For a forecast, use the expected consumption and applicable billing terms rather than assuming that this historical rate stays constant.

If a hosting contract bundles electricity and hosting services into one charge, count that charge once. Either separate its electricity and service components where the contract allows, or use the bundled charge and subtract only additional costs not already included. Do not deduct the full hosting charge again after including it in an all-in rate.

A manufacturer’s wall-power specification includes the miner’s own power-supply losses but excludes external cooling, ventilation, upstream distribution losses, and other facility loads. A site meter captures those additional loads only if they fall within its measurement boundary; a meter connected to one ASIC does not measure the whole facility. For any electricity-cost figure used in a profitability decision, appropriately scoped metered or invoiced data should take precedence over a specification-sheet estimate.

Electricity Cost in a Merged-Mining Setup

Because Dogecoin is commonly earned through Litecoin/Dogecoin merged mining, a Scrypt ASIC's total mining revenue in a given period is the sum of every credited reward it produces, not a single coin's reward in isolation:

Total Scrypt mining revenue = LTC reward value + DOGE reward value + value of other credited merged-mining coins

Net operating result before capital expenditure = Total Scrypt mining revenue - (electricity charges or bundled electricity-and-hosting charges) - remaining operating costs

Here, remaining operating costs include only costs not already included in the electricity or bundled charge, or deducted from credited rewards. Each cost should be counted once.

A single electricity bill funds all of this output at once. Dividing that bill between LTC and DOGE is an accounting choice, not a standard mining calculation, and should only be done if the operation explicitly defines an allocation method — for example, splitting the period's electricity cost in proportion to each coin's share of total reward value. Absent that explicit choice, the electricity cost should be compared against the combined value of everything the hardware produced, not against DOGE's reward value alone.

This distinction matters for how a payout method is interpreted. ViaBTC's current LTC mining documentation states that LTC miners can qualify for DOGE merged-mining rewards in proportion to their contributed work, and that this applies whether the miner has selected PPS+ or PPLNS for LTC (ViaBTC Help Center, LTC Mining). The LTC payment method and the DOGE reward distribution are governed separately: DOGE merged-mining rewards are distributed under PPLNS and credited on a recurring settlement cycle, independent of whether the miner's LTC rewards are calculated under PPS+ or PPLNS (ViaBTC Help Center, LTC Merged Mining Coins Mining Tutorial). Selecting a particular LTC payout mode does not make the DOGE component fixed, guaranteed, or free of the variance normally associated with PPLNS.

Setting a Maximum Electricity Price After Other Operating Costs

Some operators want a single number representing the maximum electricity price that mining rewards can cover after paying other operating costs. Include non-electric operating costs such as separately billed hosting services, maintenance, and other recurring expenses, whether fixed or variable, while excluding capital expenditure. This can be expressed as:

Maximum affordable effective electricity rate ($/kWh) = (Value of credited mining rewards - non-electric operating costs not already deducted from rewards) / Metered kWh

Use the combined value of all credited mining rewards. This threshold applies to electricity charges; if electricity and hosting cannot be separated, compare combined rewards with the bundled charge and remaining costs directly instead. A negative numerator means rewards do not cover the included non-electric operating costs even before paying for electricity.

Two conditions are necessary for this figure to be meaningful. First, the reward value and the energy consumption must come from the same measurement period; comparing a day's rewards against a month's energy use, or vice versa, produces a distorted result. Second, if the credited reward figure a pool reports is already net of the pool fee, that fee should not be subtracted a second time when calculating the threshold. Because this threshold is a working estimate rather than a fixed break-even guarantee, it should be treated as a planning input rather than a standing performance target.

What the Electricity Calculation Cannot Tell You

Electricity cost is one of the few inputs in mining economics that is genuinely predictable: it follows directly from power draw, runtime and the electricity rate. Mining revenue is not similarly stable. It moves with network difficulty, pool luck, actual hardware performance versus specification, pool fees, and the market price of each credited coin. Coin prices in particular can shift quickly enough to make a single-point profitability claim outdated within days, which is why any revenue comparison should be treated as a dated scenario rather than an ongoing guarantee. For this reason, an electricity-cost calculation is best used to establish a known operating cost, while revenue and profitability should be evaluated separately, using actual metered energy use and actual credited rewards for the same period.

FAQ

Can I calculate a "cost per DOGE" for a merged-mining ASIC?

Not reliably without an explicit allocation method. Because the same electricity powers the hash work that produces both LTC and DOGE rewards under merged mining, the ASIC's power bill is a shared cost. A per-DOGE cost figure would require the operation to define how it splits that shared cost between coins, which is an accounting decision rather than a standard calculation.

Does choosing PPS+ instead of PPLNS for LTC change my ASIC’s power use or DOGE reward method?

No. With the same hardware settings and runtime, selecting a different LTC payment method does not change the ASIC’s power use. DOGE merged-mining rewards remain distributed under PPLNS regardless of the selected LTC method (ViaBTC Help Center, LTC Merged Mining Coins Mining Tutorial). The LTC method does affect how LTC rewards are calculated and their variability, so it can affect the combined revenue available to cover electricity costs (ViaBTC Help Center, PPS+ and PPLNS).

Should I use a manufacturer's wall-power rating or a meter reading to estimate electricity cost?

Use a meter reading or invoice that covers the equipment and period you are assessing. An ASIC input meter measures the miner’s actual consumption, including its power-supply losses. A site meter can also capture external cooling, ventilation, and upstream distribution losses within its measurement boundary. The manufacturer’s typical wall-power specification is useful for a quick equipment-level estimate but does not capture facility-wide electricity use.

Are national average electricity prices a good stand-in for a mining site's actual rate?

They are useful only as a general reference point. Sector-average figures, such as national residential, commercial or industrial averages, reflect a broad mix of customers and regions. An individual mining operation's actual tariff depends on its specific utility contract, region, load size and any hosting arrangement, and can differ substantially from a national average.
