How to Calculate Bitcoin Mining Profitability with Simple Mining Hosting

A single Bitcoin miner running at 7,215 watts generates roughly $5.44 in daily profit at $0.05/kWh power rates. Run that same machine at typical residential rates of $0.12/kWh or higher, and you're likely losing money every day it operates.

This math explains why hosted mining has become the default choice for most individual miners in 2026. But calculating whether any specific hosting arrangement actually works for your situation requires understanding the formula, the variables, and where hidden costs lurk.

The Core Profitability Formula

Bitcoin mining profitability boils down to a simple equation:

Daily Profit = Daily Revenue - Daily Electricity Cost - Fees

Let's break down each component with current numbers.

Calculating Daily Revenue

Your share of Bitcoin's daily block rewards depends on your hashrate relative to the entire network:

Daily Revenue = (Your Hashrate / Network Hashrate) × 144 blocks × 3.125 BTC × BTC Price

As of late April 2026, the network hashrate sits around 1,004 EH/s (exahashes per second), with Bitcoin trading near $78,000. The 3.125 BTC block reward has been in effect since the April 2024 halving, and will remain until 2028 when it drops to 1.5625 BTC.

For a practical example: a 390 TH/s miner represents about 0.0000388% of total network hashrate. That translates to roughly $14.09 in daily revenue before costs.

Calculating Electricity Costs

Electricity typically consumes 75-85% of operating expenses in Bitcoin mining. The formula is straightforward:

Daily Power Cost = (Watts / 1000) × 24 hours × $/kWh

That same 390 TH/s miner drawing 7,215 watts at $0.05/kWh costs $8.66 daily to operate, leaving $5.44 in profit.

Change the power rate to $0.12/kWh (common residential pricing), and your daily power cost jumps to $20.78. You're now losing $6.69 every day the machine runs.

Why Electricity Rate Is Everything

The profitability threshold in 2026 sits around $0.10/kWh for efficient hardware. Above that, you need either exceptional equipment (under 15 J/TH efficiency) or a significant Bitcoin price increase to break even.

This is where hosting arrangements become relevant. Simple Mining offers all-in rates of $0.07-0.08/kWh at their Iowa data centers, with tiered pricing based on scale. "All-in" matters because it bundles electricity, cooling, security, and on-site repairs into a single rate.

Home mining carries hidden costs that erode apparent savings:

• Cooling overhead: Air conditioning or ventilation systems add 15-30% to base electrical consumption
• Electrical upgrades: 240V circuits and panel upgrades often run $500-2,000
• Downtime: Without 24/7 monitoring, failures can go unnoticed for hours or days
• Maintenance: Replacing fans, cleaning dust filters, and troubleshooting issues takes time

Hosted facilities typically achieve 95-98% uptime with immediate on-site repairs. That operational consistency compounds into meaningful revenue differences over a year.

Running the Numbers: Home vs. Hosted

Let's compare a realistic scenario using an Antminer S21 or similar mid-tier ASIC:

Machine specs: 390 TH/s, 7,215W

Home Mining (suburban U.S.):

• Base electricity: $0.12/kWh
• Cooling overhead: 20% additional
• Effective rate: ~$0.144/kWh
• Daily power cost: $24.93
• Daily revenue: $14.09
• Daily loss: -$10.84

Hosted Mining (Simple Mining):

• All-in rate: $0.08/kWh
• Daily power cost: $13.85
• Daily revenue: $14.09
• Daily profit: $0.24

Neither scenario looks particularly exciting at current hashprice levels (around $27.89/PH/s/day in Q1 2026, which is historically low). But one loses money while the other maintains positive, if thin, margins.

The Scale Effect

Profitability improves with scale for two reasons. First, hosting rates often decrease with volume. Second, fixed costs (your time, monitoring tools, accounting overhead) spread across more machines.

Simple Mining's tiered structure means larger deployments may access rates closer to $0.07/kWh, pushing that daily profit from $0.24 to roughly $2.41 per machine. Multiply by 10 or 50 units and the numbers become meaningful.

Tools for Real-Time Calculations

Hashrate, difficulty, and Bitcoin price fluctuate constantly. Rather than manual calculations, use these resources:

• ASIC Miner Value: Live profitability rankings for specific hardware models
• CoinWarz Bitcoin Mining Calculator: Customizable inputs for power costs and pool fees
• Hashrate Index: Network-wide metrics and hashprice tracking

Simple Mining also provides dashboard access during their 7-day trial period, letting you model profitability with actual hosting rates before committing capital.

What the Calculators Don't Tell You

Every profitability calculator assumes stable conditions. Reality is messier.

Difficulty adjustments: Network difficulty reached 135-144 trillion in recent adjustments. As more hashrate comes online (or goes offline during price dips), your revenue share changes.

Hardware degradation: ASICs lose efficiency over time. Budget for 5-10% performance decline annually.

Pool fees: Most pools take 1-3% of rewards. Factor this into your revenue calculations.

Counterparty risk: With hosted mining, you're trusting a third party with expensive equipment. Simple Mining's U.S. jurisdiction and domestic legal protections offer more recourse than offshore alternatives, but risk never disappears entirely.

The Honest Assessment

At current hashprice levels, Bitcoin mining favors operators with significant scale and access to cheap power. Individual miners running a handful of machines face thin margins that can flip negative during difficulty spikes or price drops.

The contrarian view worth considering: if you don't have access to power under $0.06/kWh, simply buying Bitcoin may deliver better risk-adjusted returns with less complexity.

That said, hosted mining at competitive rates ($0.07-0.08/kWh) keeps you in positive territory while maintaining exposure to potential upside. If Bitcoin price increases or network hashrate declines, your margins expand. If transaction fees grow as a percentage of block rewards (already happening as we approach the 2028 halving), that adds pure profit.

The math ultimately answers the question. Run your specific numbers with your specific power costs, and the spreadsheet will tell you whether mining makes sense for your situation.
