Frequently asked questions
Daily profit = revenue − electricity cost − hardware amortization. Electricity cost is rate × power draw (kW) × hours run; amortization spreads the rig’s price over its lifespan.
Ignoring the rig’s upfront cost overstates profit. Spreading it across the expected lifespan (e.g. 730 days) gives a truer daily figure and a realistic break-even.
Usually electricity. At $0.10/kWh a 3 kW rig running 24/7 costs about $7.20 a day, so cheap power is the main driver of profitability.
No. Revenue swings with coin price, network difficulty and block rewards, all of which change constantly. Treat any estimate as a snapshot, not a forecast.
Two dollars eighty a day, before the hardware
Daily revenue of $10 against electricity costing $0.10 per kWh for a 3 kW rig running 24 hours leaves a daily profit of $2.80 — about $84 a month.
The electricity bill is the dominant cost: 3 kW × 24 hours = 72 kWh a day, at $0.10 = $7.20. That is 72% of gross revenue consumed by power alone, which is the defining economic reality of proof-of-work mining.
The calculation
Daily power cost = power (kW) × hours × cost per kWh = 3 × 24 × 0.10 = $7.20
Daily profit = daily revenue − daily power cost = 10 − 7.20 = $2.80
Monthly profit = 2.80 × 30 = $84
Hardware break-even = hardware cost ÷ daily profit. With hardware entered at $0, there is no break-even to compute — but with a realistic rig at, say, $2,000, break-even would be 2,000 ÷ 2.80 = 714 days, close to two years, and that is before any of the factors below.
What makes the projection unreliable
Mining revenue is not fixed. Four variables move it, all outside your control:
Network difficulty adjusts to keep block times constant as total mining power changes. As more miners join, your share of rewards falls — difficulty has risen relentlessly over Bitcoin's history, meaning identical hardware earns steadily less over time.
Coin price swings the dollar value of a fixed coin reward.
Block subsidy halvings cut the reward per block by half roughly every four years. A halving is an instant 50% revenue reduction for every miner simultaneously.
Transaction fees supplement the subsidy and vary with network congestion.
The practical consequence is that a break-even calculated on today's figures is optimistic, because difficulty almost always rises during the payback period. A rig projecting a two-year payback frequently does not achieve it.
Costs the calculator does not include
Cooling. A 3 kW rig produces 3 kW of heat. In a warm climate, cooling can add 10–30% to the power draw, and in India that is a substantial addition.
Hardware degradation and failure. Fans, power supplies and boards fail under continuous load. Budget for replacement parts and downtime.
Pool fees, typically 1–3% of rewards.
Downtime for maintenance, power cuts and network outages — the calculation assumes 24 hours a day, every day.
Space, noise and infrastructure. Industrial-grade mining is not a domestic activity; the noise alone rules out most homes.
The Indian position
Two specific considerations make mining unattractive in India relative to other jurisdictions:
Electricity cost. Domestic tariffs commonly run ₹6–₹10 per unit — roughly $0.07–$0.12 — but slab-based pricing means heavy consumption is charged at the highest rates, and commercial tariffs are higher still. The $0.10 assumed here is optimistic for a domestic connection running 72 kWh a day.
Tax treatment. Mining rewards are taxable as income at receipt, and under Section 115BBH the subsequent disposal is taxed at 30% with no deduction for the cost of mining — not the electricity, not the hardware. The infrastructure cost that makes mining possible is explicitly non-deductible, which materially worsens the after-tax economics compared with almost any other business activity.
Reading the result
Treat the profit figure as a snapshot at today's difficulty and price, valid for days rather than months. Re-run it whenever either moves materially.
The break-even days figure is the one that matters for a purchase decision, and it should be stress-tested: recompute assuming difficulty rises 30% over the period and the coin price falls 30%. If the investment still works under both, it is worth considering; if it only works at today's figures, it probably is not.
Common mistakes
Assuming constant difficulty. It rises, and your revenue falls with it.
Omitting cooling load. It can add a third to power consumption.
Using domestic tariff rates for continuous heavy load. Slab pricing pushes you into the top band.
Ignoring the non-deductibility of costs. Indian tax allows no deduction for electricity or hardware.
Assuming 100% uptime. Real availability is lower, and the calculation is linear in hours.
