For Bitcoin ASICs, power is the main operating expense. Hashrate ads look exciting; the monthly DISCOM bill is what keeps miners honest.

This guide explains the simple math behind electricity cost and break-even thinking in an India context, then points you to the live mining calculator on P2P Miner Store so you can plug in your own tariff.

The three numbers that matter

Hashrate (TH/s) — how much work the machine contributes
Power draw (W) — wall power, not chip fantasy watts
Electricity price (₹/kWh) — your real all-in rate

Everything else (pool fee, uptime, ambient heat throttling) adjusts those three.

Daily energy formula

Daily kWh = (Power in watts ÷ 1000) × 24 × number of units
Daily power cost (₹) = Daily kWh × your ₹ per kWh

Example: one miner at 3,550 W and ₹8/kWh:

kWh/day ≈ 3.55 × 24 = 85.2 kWh
Power cost/day ≈ 85.2 × 8 = ₹682
Monthly power (×30) ≈ ₹20,450 before any other costs

If revenue in INR is below that power line, you are paying for the privilege of heating a room.

Efficiency: J/TH

Efficiency is often quoted as joules per terahash (J/TH):

J/TH = watts ÷ TH/s

Lower J/TH means less electricity per unit of hashrate. Newer generations tend to improve efficiency — which is why old miners die first when difficulty rises or power is expensive.

What ₹/kWh should you use?

Use the rate you will actually pay, not a marketing spreadsheet:

Context	What to check
Home / residential	Slab rates, fixed charges, time-of-day if any
Shop / commercial	Commercial tariff category
Industrial / warehouse	Contract demand, energy charges, penalties
Hosted mining	Host’s all-in $/kWh or ₹/kWh (often includes margin)

Illustrative only: many Indian residential users effectively pay high enough rates that home mining is unattractive; some industrial setups with surplus or special arrangements can look very different. Always use your bill.

Also remember:

ASICs want stable voltage and clean installs
Heat in Indian summers can force underclocking or failures
Noise makes residential mining a neighbour problem, not only a math problem

Break-even thinking (simple)

Operating break-even (power only):

Revenue from BTC mined (in ₹) ≥ electricity cost (in ₹)

The calculator on P2P Miner Store shows this as net profit after electricity.

Full project break-even also needs:

ASIC purchase price (and shipping / duty if imported)
Networking, PDUs, cooling, racks
Maintenance, downtime, travel to the site
Pool fees and eventual hardware resale value

If power-only profit is tiny, full ROI is usually worse.

How difficulty and price move the goalposts

Even with a fixed tariff:

BTC price up → revenue in INR up (for the same BTC mined)
Network hashrate up → your share of rewards down
Difficulty adjustments (~every two weeks) rebalance block times

That is why a machine that “worked” last year can be unprofitable this year at the same ₹/kWh.

Practical workflow

List candidate miners (or use the dropdown list).
Note nameplate TH/s and W.
Enter your ₹/kWh and pool fee in the Bitcoin mining calculator.
Stress-test: re-run at ₹6, ₹8, ₹10, ₹12 per kWh.
Ask: does profit survive a 20–30% drop in BTC price or a hashrate jump?

If only the optimistic case works, you do not have a robust plan.

Need a second pair of eyes?

Power tariffs, custody, and “should we even mine?” are strategy questions as much as spreadsheet questions. Book a consultation if you want a calm, India-focused review before you spend on hardware.
