How Does Co-Mining Make Money? Costs and Profit Sharing Explained

As cryptocurrency mining becomes more capital-intensive and professionally managed, many energy providers and infrastructure owners are seeking ways to monetize their excess power, substation, and land resources.

Traditional options come with limitations. Buying and operating mining equipment independently requires significant capital expenditure (CAPEX), while simply leasing out land or facilities may generate only modest fixed rental income.

Co-mining offers an alternative built around resource sharing. Rather than a traditional service arrangement, it brings together power resources and mining expertise to turn underused or low-cost electricity into cryptocurrency mining revenue.

This blog explains how co-mining works, what costs are involved, and how profits are calculated and shared, helping resource owners evaluate the actual economics of a potential project.

What Is Co-Mining?

Co-mining is an industrial-scale partnership model built around complementary resources and shared returns.

Typically, the resource partner (customer) provides power, a suitable site, or supporting infrastructure, while the mining partner contributes a fleet of high-performance mining machines, deployment expertise, and professional operations and maintenance services. Both parties participate in the project and share the resulting net proceeds according to their agreement.

How Co-Mining Works

The basic idea behind co-mining is straightforward: “You bring the power and the site. We bring the miners and operational expertise. Together, we turn electricity into digital assets.”

For resource owners with access to low-cost electricity, such as hydropower, solar power, or associated gas, or existing substation infrastructure, independently purchasing thousands of modern mining machines could require millions or even tens of millions of dollars in upfront investment.

Beyond the equipment costs, they would also need to manage complex hardware supply chains, cooling infrastructure, and round-the-clock on-site operations.

Co-mining reduces the capital required to launch a project independently. Instead of funding an entire mining fleet, resource owners can contribute their existing resources and participate directly in the proceeds generated by cryptocurrency mining.

Co-Mining vs. Mining Hosting: Key Differences

Both models involve operating mining hardware in professional facilities, but they differ significantly in asset ownership, financial settlement, and risk allocation.

Mining hosting follows a “buy equipment + purchase operating services” model. The customer owns 100% of the mining hardware, while the hosting provider earns electricity-related charges and service fees.

Co-mining follows a “contribute resources + form a partnership” model. It combines power resources, mining hardware, and operational capabilities under a shared commercial arrangement.

Under hosting, mining output belongs to the customer, who pays electricity and hosting fees separately, typically on a monthly basis. The customer bears the resulting profit or loss.

Under co-mining, the project first deducts agreed operating costs from mining revenue. The remaining net proceeds are then distributed according to the contractual profit-sharing ratio, such as 50/50 or 60/40.

The risk structures are also different. In hosting, hardware depreciation, falling cryptocurrency prices, and periods of unprofitable operation primarily affect the equipment owner.

In co-mining, both parties' returns are tied more closely to overall project performance. Power outages or weak market conditions can reduce returns for both partners, while stronger mining economics allow both parties to share in the upside.

What Are the Main Costs of Co-Mining?

Co-mining does not mean operating a mining project at zero cost.

Although the resource partner may not need to purchase an entire mining fleet independently, electricity, hardware, site infrastructure, and day-to-day operations still generate expenses that must be accounted for at the project level.

Electricity Costs

Electricity is one of the largest and most consistent operating expenses (OPEX) in a mining project.

Power prices directly affect operating margins. Lower electricity rates give miners more room to remain profitable when market conditions weaken and hashprice falls. Higher rates, on the other hand, can push miners toward their shutdown threshold sooner.

Mining Hardware and Equipment Costs

A high-performance ASIC mining fleet, transformers, high- and low-voltage switchgear, network switches, cooling systems, and spare parts account for a substantial portion of a project's capital investment.

Cooling infrastructure may include air-cooled mining facilities or hydro-cooling containers, depending on the deployment.

Even when the mining partner supplies the hardware or both parties share the upfront investment, equipment purchase costs and depreciation still affect how profits are distributed.

For example, a contract may allow the hardware provider to recover equipment costs first or set aside a portion of revenue as a depreciation reserve before the remaining proceeds are shared.

Site and Infrastructure Costs

Land leases, facility construction, high-voltage grid interconnections, racks, cabling, fire protection, and security systems all contribute to the cost of preparing a mining site.

Co-mining requires more than access to electricity. The reliability and redundancy of the underlying infrastructure also determine whether a project can meet applicable compliance requirements and operate consistently over the long term.

Operations and Maintenance Costs

A mining fleet requires 24/7 automated monitoring, regular dust removal, hardware troubleshooting, and on-site board-level repairs.

Every hour a miner remains offline means lost mining output. As a result, downtime management, spare-parts replacement speed, and the technical capabilities of the operations team directly affect project revenue and operating costs.

Mining Pool Fees and Other Operating Expenses

Mining pool fees, typically around 1%–2%, are another recurring project expense.

Other costs may include commercial internet connectivity, property insurance, compliance audits, management services, and financial settlement.

Although these expenses may appear relatively small individually, they can add up over time and reduce the project's final net profit.

How Is Co-Mining Profit Calculated?

To understand how co-mining makes money, it is important to distinguish between gross project revenue and net proceeds.

Co-mining does not simply divide the total amount of Bitcoin mined each day between the partners. The actual costs required to operate the project must be deducted first.

Net Proceeds Calculation

A basic financial model can help explain the project's cash flow:

Project Net Proceeds ≈ Gross Mining Revenue − Actual Electricity Costs − On-Site Operating Expenses − Mining Pool Fees − Hardware Repair and Spare-Parts Reserves − Other Agreed Operating Costs

In practice, the specific expenses that can be deducted before profit sharing depend entirely on the agreement between the two parties.

Why You Can’t Rely on Bitcoin Price Alone

One common mistake among beginners is focusing only on the price of Bitcoin.

In reality, a key metric for mining revenue is hashprice, which measures the daily fiat-denominated revenue generated by a unit of hashrate, such as TH/s, over a given period.

Hashprice is influenced by three major factors: Bitcoin's price, network mining difficulty, and transaction fees.

If network difficulty rises sharply or electricity prices increase, a project's net proceeds can decline even when Bitcoin's market price remains unchanged.

That is why evaluating co-mining profitability requires ongoing analysis of mining difficulty and electricity costs, not just cryptocurrency prices.

How Are Co-Mining Profits Shared?

Once the agreed project expenses have been deducted and net proceeds have been calculated, the remaining amount is distributed between the partners according to the contractual profit-sharing ratio.

If the resource partner provides exceptionally low-cost electricity, an existing substation, and the necessary regulatory approvals, these contributions may substantially reduce the project's capital requirements. In such cases, the resource partner may be able to negotiate a larger share of the net proceeds.

Conversely, if the site requires major electrical infrastructure upgrades and the mining partner must fund the entire hardware investment, the mining partner may receive a larger share.

Co-mining agreements often run for two to five years.

Some contracts also include a hardware cost recovery period. During the early stages of the project, a portion of the proceeds may be allocated to recovering equipment purchase costs. Once those costs have been recovered, the standard net-profit-sharing ratio takes effect.

Who Takes the Risk, and Who Gets the Return?

Co-mining is not just about sharing profits. It is also a commercial arrangement in which both parties share project risks.

If Bitcoin prices fall sharply or network difficulty rises significantly, hashprice may decline to a level where net proceeds shrink or miners approach their shutdown threshold. Both parties are exposed to the resulting reduction in returns.

Hardware aging, declining hashrate, and heat-related chip wear may be addressed through spare-parts reserves or other arrangements defined in the partnership agreement.

If a site experiences unexpected power outages, unstable voltage, or grid disconnection, the resource partner may be responsible for failing to meet its power-supply obligations.

Likewise, if operational mistakes cause extended miner downtime, the operating partner may be responsible for the resulting efficiency losses.

What Makes a Co-Mining Project More Profitable?

The long-term success of a co-mining project depends less on the headline hashrate promoted in marketing materials and more on whether its underlying resources work well together.

Competitive electricity rates, reliable infrastructure, energy-efficient mining hardware, and professional operations are the foundations of a project that can remain viable across different market cycles.

Low-Cost and Reliable Electricity

Electricity is the lifeline of a mining project. Lower power costs provide a wider operating margin, allowing miners to remain profitable even when network difficulty increases or market conditions weaken.

Reliable power is equally important because it directly affects miner uptime.

A site may offer attractive electricity rates, but frequent unplanned outages or major voltage fluctuations can create lost mining revenue and additional hardware wear. Over time, these losses can quickly erase the savings from cheaper electricity. Both low cost and reliability matter.

Suitable Site Conditions

A qualified co-mining site needs more than an approved grid interconnection.

It also requires sufficient physical space, adequate transformer capacity, efficient cooling, strong security, and reliable commercial network connectivity.

The site's ability to expand into tens of megawatts (MW) can also influence its long-term growth potential.

The more developed the existing infrastructure, the less additional capital may be required for upgrades. This can make project launch and ongoing maintenance costs easier to manage.

Efficient Mining Hardware and Professional Operations

A miner's energy efficiency, measured in joules per terahash (J/TH), determines how much hashrate it can generate from a given amount of electricity.

More energy-efficient mining hardware consumes less electricity per unit of hashrate, which can improve overall operating margins.

A professional on-site operations team is equally important in turning rated hashrate into actual mining revenue.

Through 24/7 automated monitoring, precise temperature control, and timely board-level repairs, the team can minimize downtime and maintain stable hashrate output.

Who Is Co-Mining Best Suited For?

Co-mining is designed for a specific type of participant and is not suitable for everyone.

It is generally best suited to resource owners with access to valuable electricity, land, or infrastructure who may lack the capital, engineering expertise, or operational capabilities needed to deploy and manage a mining fleet independently.

Power Resource Owners

If you have access to low-cost, reliable, and scalable electricity, such as hydropower, solar power, wind power, or associated-gas generation, but do not want to make a major investment in mining equipment, co-mining may provide a way to monetize those resources.

Instead of leaving available power unused or underutilized, you can contribute it to a mining project and participate in the proceeds generated from digital asset production.

Site and Infrastructure Owners

Owners of unused industrial facilities, high-voltage substations, or available power-distribution capacity at existing data centers may also find co-mining attractive.

By contributing site and electrical infrastructure while relying on a partner's hardware and operating capabilities, they may be able to put existing assets to work without taking on the full capital burden of developing a mining operation independently.

Partners Looking to Reduce Hardware Investment

Co-mining may also appeal to investors who see potential in mining revenue but do not want to independently bear the costs of a large hardware purchase or the complexity of day-to-day operations.

By contributing suitable site resources or capital and working with a professional mining operator, they can participate in the project's long-term net proceeds while sharing certain hardware-related and operating risks.

What Should You Ask Before Entering a Co-Mining Partnership?

Before signing a co-mining agreement, resource owners should focus less on advertised return projections and more on whether project costs, financial deductions, and each party's responsibilities are clearly defined.

Three areas deserve particular attention:

1. Are the electricity terms competitive enough? Where does the local electricity rate fall on the broader mining cost curve? Is power available reliably around the clock, or are there seasonal constraints, such as changes in hydropower availability?
2. Are the cost deduction rules clearly defined? Which expenses can be deducted before net proceeds are shared? How is electricity billed? Does the hardware partner have the right to recover equipment costs before the standard profit split begins?
3. Are profit sharing and exit terms clearly established? How often are net proceeds calculated and distributed? Who has the authority to shut down miners during extreme market conditions or when the shutdown threshold is reached? What happens to the equipment and site when the contract expires?

Common Misconceptions

Low electricity prices alone do not make a good co-mining project. Transformer capacity, power reliability, cooling conditions, network connectivity, and local regulatory requirements all affect whether a site is viable. Access to electricity without suitable infrastructure may not be enough to attract a qualified hardware partner.

Co-mining may reduce the customer's direct hardware purchasing costs, but contributed land, power capacity, and substation infrastructure still represent committed capital. If a project fails because of unreliable electricity or poor operations, the resource partner may face idle infrastructure and lost opportunities to use those assets elsewhere.

A higher profit-sharing percentage also does not necessarily mean a better financial outcome. Pursuing the highest possible split may come at the expense of hardware quality or operational performance. A project with a slightly smaller profit share but efficient operations and uptime above 98% may generate more actual net proceeds than one offering a larger share but suffering frequent power or network outages.

The Core of Co-Mining: Turning Resources into Net Proceeds

The economics behind co-mining are relatively straightforward: combine competitive power and site resources with energy-efficient mining hardware and professional operations, generate blockchain mining rewards, deduct agreed operating costs, and distribute the remaining net proceeds according to the contract.

Evaluating a co-mining opportunity requires more than looking at projected gross mining revenue or potential Bitcoin price increases.

Instead, the focus should be on the full project economics, including electricity costs, hardware efficiency, operational capabilities, downtime, and the rules governing net-proceeds calculations.

If your main advantage is access to low-cost electricity or underused infrastructure, and you want to monetize those resources without funding an entire mining fleet yourself, co-mining may be worth exploring.

The key is to understand the cost structure and clearly define each party's risks before the project begins, so the partnership is built on sound engineering and financial assumptions.

When evaluating a co-mining site's power strategy and mining cash flow, a clear model of hashrate and electricity costs is essential.

You can use the Bitdeer Mining Calculator to enter specific mining hardware specifications, electricity rates, and expected network difficulty to estimate mining revenue and cash flow. These calculations can provide a useful data baseline for evaluating the financial performance of a potential co-mining project.
