Electricity Costs & Mining Profitability
Electricity is the single largest ongoing expense in cryptocurrency mining, typically accounting for 60-80% of operating costs. Understanding and optimizing your power consumption can mean the difference between profitable mining and losing money. This guide covers everything you need to know about electricity and mining in 2026.
Why Electricity Costs Matter So Much
Mining hardware runs 24 hours a day, 7 days a week. Even small differences in electricity rates compound into significant cost differences over time. Consider this example with an Antminer S21 XP (3,645W):
| Electricity Rate | Daily Cost | Monthly Cost | Yearly Cost | Impact on Profit |
|---|---|---|---|---|
| $0.03/kWh | $2.62 | $79.72 | $956.66 | Highly profitable |
| $0.05/kWh | $4.37 | $132.86 | $1,594.37 | Profitable |
| $0.08/kWh | $7.00 | $212.57 | $2,550.83 | Marginally profitable |
| $0.10/kWh | $8.75 | $265.72 | $3,188.54 | Near break-even |
| $0.15/kWh | $13.12 | $398.58 | $4,782.81 | Unprofitable for most |
| $0.25/kWh | $21.87 | $664.29 | $7,971.35 | Heavily unprofitable |

How to Calculate Mining Electricity Costs
The formula is straightforward:
Daily cost = (Watts / 1000) x 24 hours x electricity rate ($/kWh)
For a 6-GPU rig drawing 1,200W at $0.10/kWh:
- Daily: (1200 / 1000) x 24 x $0.10 = $2.88/day
- Monthly: $2.88 x 30.44 = $87.67/month
- Yearly: $2.88 x 365 = $1,051.20/year
Remember to include power supply inefficiency. An 80+ Gold PSU operates at approximately 90% efficiency, meaning your actual wall power draw is about 10% higher than the sum of component power consumption.
Electricity Rates by Country
Your geographic location dramatically affects mining viability. Here are average residential and industrial electricity rates for the most relevant mining regions:
| Country/Region | Residential Rate | Industrial Rate | Mining Viability |
|---|---|---|---|
| Paraguay | $0.03-0.04/kWh | $0.02-0.03/kWh | Excellent |
| Kazakhstan | $0.03-0.05/kWh | $0.03-0.04/kWh | Excellent |
| Russia | $0.03-0.06/kWh | $0.03-0.05/kWh | Excellent |
| USA (Texas, WA) | $0.05-0.09/kWh | $0.04-0.07/kWh | Good |
| Canada (Quebec, BC) | $0.05-0.08/kWh | $0.04-0.06/kWh | Good |
| USA (Average) | $0.12-0.16/kWh | $0.07-0.10/kWh | Moderate |
| UAE | $0.08-0.10/kWh | $0.06-0.08/kWh | Good |
| China (restricted) | $0.05-0.10/kWh | $0.04-0.07/kWh | Banned in most regions |
| UK | $0.28-0.35/kWh | $0.15-0.22/kWh | Poor |
| Germany | $0.30-0.40/kWh | $0.15-0.25/kWh | Poor |
| Australia | $0.20-0.30/kWh | $0.10-0.18/kWh | Poor to moderate |
Break-Even Electricity Price
The break-even electricity price is the maximum rate at which your miner covers its electricity costs (earning zero profit on hardware investment). It varies by hardware and coin:
| Hardware | Coin | Break-Even Rate (approx.) |
|---|---|---|
| Antminer S21 XP (270 TH/s) | Bitcoin | ~$0.09/kWh |
| Antminer S21 (200 TH/s) | Bitcoin | ~$0.07/kWh |
| Whatsminer M50S (126 TH/s) | Bitcoin | ~$0.04/kWh |
| RTX 4070 Ti | Ethereum Classic | ~$0.12/kWh |
| RTX 3060 Ti | Ethereum Classic | ~$0.07/kWh |
| RX 7900 XTX | Kaspa | ~$0.10/kWh |
These rates fluctuate with coin prices and difficulty. Use our Mining Profitability Calculator for current break-even rates.
Understanding Your Electricity Bill
Your actual electricity cost may be higher than the simple per-kWh rate suggests. Watch for these billing components:
Tiered Pricing
Many utilities charge higher rates as usage increases. Mining can push you into expensive tiers. A home using 800 kWh/month might pay $0.10/kWh, but adding a mining rig that uses 900 kWh/month could push total usage to 1,700 kWh, where the marginal rate might be $0.18/kWh.
Time-of-Use (TOU) Rates
Some utilities offer different rates depending on the time of day. Mining rigs run 24/7, so you pay a blended rate. TOU plans with cheap off-peak rates (nights and weekends) can reduce average costs if off-peak pricing is sufficiently low.
Demand Charges
Commercial and some residential plans include demand charges based on peak power draw (measured in kW). A 6-GPU rig consistently drawing 1.5 kW may trigger demand charges that add $10-50/month to your bill depending on your utility.
Additional Fees
Fixed monthly charges, transmission fees, taxes, and renewable energy surcharges can add 15-30% on top of the base kWh rate. Always calculate using your total bill divided by total kWh consumed to get your true effective rate.
Measuring Actual Power Consumption
Never rely solely on manufacturer specifications for power consumption. Actual draw varies based on overclocking, ambient temperature, and PSU efficiency. Use these methods to measure real consumption:
- Kill-A-Watt meter — plug-in device for single outlet measurement ($20-30)
- Smart plug with energy monitoring — TP-Link Kasa or similar ($15-25)
- Clamp meter on the circuit breaker — measures total circuit draw
- Mining software readout — shows GPU-only power (does not include system overhead)
System overhead (CPU, motherboard, fans, PSU losses) typically adds 100-200W on top of GPU power draw for a multi-GPU rig.
Reducing Electricity Costs
Several strategies can lower your effective electricity rate:
- Negotiate commercial rates — if running multiple rigs, commercial/industrial power is often 30-50% cheaper
- Solar power — eliminate ongoing electricity costs with upfront solar investment
- Off-peak mining — if on a TOU plan, mine at full capacity during cheap hours only
- Efficient hardware — newer GPUs and ASICs produce more hashrate per watt
- Undervolting — reduce GPU voltage to cut power 20-30% with minimal hashrate loss
- Relocate — some miners move operations to low-cost electricity regions

Power Supply Efficiency Ratings
Your PSU's efficiency rating determines how much power is wasted as heat during conversion from AC to DC power:
| Rating | Efficiency at 50% Load | Extra Cost per Year (1500W rig) |
|---|---|---|
| 80+ Bronze | 85% | ~$200 wasted |
| 80+ Gold | 90% | ~$130 wasted |
| 80+ Platinum | 92% | ~$100 wasted |
| 80+ Titanium | 94% | ~$75 wasted |
At $0.10/kWh, upgrading from Bronze to Gold saves roughly $70/year per rig. For multiple rigs, the savings justify the higher PSU cost.
FAQ
A single GPU uses 100-350W. A 6-GPU rig uses 700-1800W total. A Bitcoin ASIC uses 3,000-5,700W. Use our Electricity Cost Calculator to estimate your power costs based on specific hardware.
With a current-gen Antminer S21 XP, the break-even rate is approximately $0.09/kWh in 2026. Older miners break even at lower rates. Use our Bitcoin Mining Calculator to find your exact break-even price.
Mining becomes challenging above $0.10/kWh and generally unprofitable above $0.15/kWh. The exact break-even depends on your hardware, coin choice, and market prices. Check our Mining Profitability Calculator.
Paraguay ($0.03-0.04/kWh), Kazakhstan ($0.03-0.05/kWh), Russia ($0.03-0.06/kWh), and parts of the US like Texas ($0.04-0.07/kWh) offer the cheapest electricity for mining.
Yes. A 6-GPU rig needs approximately 4-6 kW of solar panels. Upfront cost is $8,000-15,000 but eliminates ongoing electricity costs. Solar mining works best in sunny regions paired with battery storage for 24/7 operation.
