<h1>Bitcoin Mining Electricity Breakeven in 2026: The Formula</h1><p>Bitcoin mining's breakeven electricity rate is the money available for power divided by the electricity the operation consumes. There is no single rate that makes every miner profitable in 2026: revenue, equipment efficiency, cooling, and other expenses differ. Calculate the threshold for your machine using current revenue inputs and measured consumption, then compare it with your actual tariff. The worked figures below are hypothetical assumptions, not a September 2026 profitability quote.</p><h2>Start with daily revenue in matching units</h2><p>Hashprice expresses mining revenue relative to computing power over time. <a href="https://data.hashrateindex.com/insights/hashprice">Hashrate Index's hashprice data</a> provides a reference for this metric; when using a dollar series, check its units and observation time. Do not mix a value per petahash per day with a machine specification expressed in terahashes per second without converting the capacity.</p><p>Assume a machine supplies 200 TH/s, equal to 0.2 PH/s, and the chosen hypothetical hashprice is $40 per PH/s per day. Multiplying 0.2 by $40 gives $8 of modeled daily revenue. This treats the machine as operating at that effective capacity throughout the day and does not promise a particular pool payout.</p><p>Now assume a 2% pool charge applied to that revenue. The deduction is $0.16, leaving $7.84. Check whether your own revenue estimate already includes pool fees before subtracting them: charging the same expense twice would understate the amount available for power.</p><h2>Measure the whole electricity requirement</h2><p>Power is a rate; energy is consumption over time. A machine drawing 3 kilowatts for 24 hours consumes 72 kilowatt-hours. A tariff quoted per kWh applies to that energy quantity, not directly to the machine's hash rate or the number printed beside its model name.</p><p>Suppose ventilation and other attributable equipment add 8 kWh daily. The operation then uses 80 kWh per day. Omitting those extra loads would make the permissible electricity price look higher than the business can actually afford.</p><p>Use measured consumption when available and compare it with the meter boundary on your bill. A machine's own display may exclude room fans or cooling equipment. If several machines share those systems, allocate consumption consistently rather than assigning all cooling to one unit or ignoring it everywhere.</p><h2>Calculate the threshold you actually mean</h2><p>For an electricity-only comparison after the assumed pool fee, divide $7.84 by 80 kWh. The result is $0.098 per kWh, or 9.8 cents. At that rate, modeled revenue covers power but leaves nothing for repairs, administration, or recovering the purchase price.</p><p>Add a hypothetical $0.64 daily allowance for other operating expenses. Power can now consume at most $7.20 daily, giving an operating breakeven rate of $7.20 divided by 80, or $0.09 per kWh. The distinction matters: a tariff below 9.8 cents can still exceed the nine-cent threshold after those other costs.</p><p>If your budget also requires $3 per day toward hardware cost recovery, only $4.20 remains for electricity. The resulting planning threshold is $0.0525 per kWh, or 5.25 cents. This allowance is a budgeting assumption, not a statement about tax depreciation or a guarantee that the machine will last long enough to recover its cost.</p><h2>Compare with the bill, including tariff structure</h2><p>A headline energy rate may exclude delivery charges, taxes, fixed fees, or demand charges. Read the tariff and decide which charges are incremental to mining and which belong in the full project budget. For a simple flat-rate case, divide attributable daily electricity cost by attributable daily kWh to obtain a comparable effective rate.</p><p>At a hypothetical seven cents per kWh, the example operation spends $5.60 daily on power. Subtracting that and $0.64 of other operating costs from $7.84 leaves $1.60. It produces a positive modeled operating margin, but falls $1.40 short of the additional $3 daily hardware-recovery allowance.</p><p>Time-dependent tariffs require a schedule rather than one universal multiplication. Turning equipment off during expensive hours changes both revenue and electricity consumption. Some expenses continue while the machine is idle, so reducing operating hours does not reduce every budget item proportionally.</p><h2>Recalculate when the revenue assumption changes</h2><p>Using the same machine and consumption assumptions, a hypothetical hashprice decline to $30 reduces gross daily revenue to $6. After the assumed 2% pool charge, $5.88 remains. Deducting $0.64 and dividing by 80 gives a revised operating threshold of $0.0655 per kWh. The seven-cent tariff that previously left a margin now exceeds that threshold.</p><p>This sensitivity is why Bit.Fan's discussion of <a href="https://www.bit.fan/en/academy/category-6/crypto-mining-profitable-2026-bitcoin-mining-profitability-electricity-keyName-kw-01195">mining profitability and electricity costs</a> treats mining as an operating decision involving equipment and upkeep. A favorable electricity contract cannot freeze mining revenue, and a higher Bitcoin price alone does not specify what a given machine will earn.</p><p>Save the date, hashprice definition, effective hash rate, energy measurement, and expense assumptions with each calculation. Compare the modeled result with actual pool receipts and bills over the same period. When those disagree, first identify which input changed; repeatedly adjusting a calculator without checking the underlying measurements can hide the expense that determines whether running the machine makes sense.</p>
