Determining Costs

How to determine if your rig is worth the cost of power..

True cost of ownership

Let’s first determine all the costs associated with your rig. This shall be your true cost of ownership.

  1. The rig itself, not including any compute units
  2. The compute units
  3. Network cables, risers, power cords.
  4. Cost of infrastructure (internet, switches, routers, VPN).
  5. Facility costs, including racks.

Fixed Costs

Any kind of one-time cost, or cost that does not change based on activity.

  • equipment
  • infrastructure
  • facility rent or membership

Variable Costs

Cost that is based on activity. Such as:

  • power usage * power price
  • mining fees

Using Crossbelt to calculate these costs

You can use the crossbelt cu cost command to help show the cost of running rigs 24⁄7. These calculators are similar to many online calculators, however the power seen here is fed directly from the compute unit and represents a better real-world value.

Note This does not include the cost of running the rig by itself without compute units.

Options for cost

-c, --costs, --costs=arg                                 - Equipment or other fixed costs, ie. $1500.00 (default: none)
-f, --fees, --fees=arg                                   - Miner and Pool fees in percent ie. 0.04 (default: none)
--[no-]json                                              - Show output in json format
-m, --monthly_facility_cost, --monthly_facility_cost=arg - Per Compute Unit Monthly Facility Cost, ie. $5.73 (default: none)
-p, --price, --price=arg                                 - Power cost per KWh, ie 0.10 (default: none)
--[no-]table                                             - Show output in table format
--units, -g arg                                          - Which compute units to include (comma and/or range) 0-1,2,4-5 (default: none)
--[no-]usd, --[no-]usd                                   - Show cost in usd instead of BTC
  • -c Equipment cost, but is currently not used and will be available in a later ROI command.
  • -f The fees as a percentage that are taken from your net profit. (Pool fees, miner fees. Typically 4 %)
  • -p The monthly facility cost in USD on a per compute unit basis. Take monthly price and divide by total number of compute units.
  • --usd Show cost in US dollars instead of micro BTC.
  • --json Show output in JSON format.
