Explanation

The meter bill the rig creates.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

kW = watts ÷ 1000 = 3250 ÷ 1000

Result: 3.25 kW

Step 2

Daily kWh = kW × 24

Result: 78.0 kWh

Step 3

Daily cost = kWh × rate = 78.0 × $0.08

Result: $6.24

Final Answer

$6.24

Worked Examples

See how the calculator works with different scenarios.

Scenario

The mining electricity cost calculator run on the values above, showing the full calculation path.

Inputs

power:3250

elecRate:0.08

Calculation

1. kW = watts ÷ 1000 = 3250 ÷ 1000 → 3.25 kW 2. Daily kWh = kW × 24 → 78.0 kWh 3. Daily cost = kWh × rate = 78.0 × $0.08 → $6.24

Result

Daily Electricity Cost: $6.24 /day

Interpretation

Power is usually 60–80% of mining opex — the rate decides the machine.

Understanding Your Result

Your Result: Daily Electricity Cost: $6.24 /day

What This Means

The meter bill the rig creates.

Why It Matters

Power is usually 60–80% of mining opex — the rate decides the machine.

Professional Interpretation

Power is usually 60–80% of mining opex — the rate decides the machine.

How this is calculated

Meter math: energy used times the tariff.

What drives the result

Daily coins ≈ (your hashes ÷ network hashes) × blocks per day × block reward. Revenue = coins × price × (1 − pool fee). Profit = revenue − power cost − other costs. Payback = hardware ÷ daily profit.

Recommendations

•Above ~$0.10/kWh most older ASICs go negative.
•Include cooling and PSU losses (+5–10%).

Educational Content

Introduction

Mining turns electricity and hardware into coins. Revenue follows hashrate share of network difficulty times coin price; profit subtracts power and pool costs. Difficulty retargets roughly every two weeks, so every figure here is a snapshot.

Concept Explanation

Applications

▸Sizing an ASIC purchase

▸Choosing a power rate or host

▸Stress-testing halvings and difficulty jumps

▸Comparing staking vs mining yield

Benefits

•Difficulty-aware revenue math
•Power-first cost view
•Payback and ROI on one page

Limitations

•Difficulty and price move constantly
•Pool luck and downtime approximated via uptime
•Firmware efficiency gains not modeled

Best Practices

•Re-run after each difficulty epoch
•Add 5–10% for cooling and PSU loss
•Model the next halving before buying hardware

Common Misconceptions

Myth: Hashrate alone sets earnings

Truth: Share of network difficulty sets earnings — rising difficulty cuts everyone.

Myth: Paper payback equals real payback

Truth: Difficulty growth stretches real payback well past the day-one figure.

Practical Tips

•Include PSU and cooling losses.

Common Mistakes

Using nameplate watts

Measure at the wall.

Assumptions

This calculator makes the following assumptions to provide estimates:

24h operation: Pro-rate downtime separately.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Difficulty and price move constantly

Limitation: Pool luck and downtime approximated via uptime

Limitation: Firmware efficiency gains not modeled

Frequently Asked Questions

Answers to common questions about this calculator.

What rate kills ASICs?

Above ~$0.10/kWh most older units go negative.

How accurate is the mining electricity cost calculator?

Every figure follows directly from the inputs using the stated formula, so it is accurate to the quality of the values you enter. Markets move — re-run with fresh prices, difficulty and rates before acting.

Do these calculators use live prices?

No — you enter prices manually so every figure is reproducible. Re-run with current quotes before trading.

Are fees included?

Yes where the mode asks for them. Enter exchange, pool and network costs explicitly for net figures.
