Calculation bench

Private AI decision tools that show their working.

Use the tools to expose assumptions, not to manufacture certainty. They can recommend a hosted route, show no break-even, leave optional income at zero and keep crypto market risk visible.

Recommended order

Fit, power, ownership cost, optional income

Running the numbers in this order keeps speculative revenue from deciding whether the equipment belongs in the business.

  1. 01

    Test technical fit

    Find the memory, demand and facility questions that need proof.

  2. 02

    Model power and cooling

    Use measured wall power when available and keep the tariff editable.

  3. 03

    Compare whole-life cost

    Put support, facilities and finance beside the hosted alternative.

  4. 04

    Stress-test spare capacity

    Only after the base case works, model an opt-in marketplace pilot.

Tool ledger

What each tool answers and what it cannot

Defaults are starting values. Replace them with current supplier, site and workload evidence before using an output commercially.

Technical fit

Server sizing tool

Use per-GPU memory, active demand and facility type to find the next evaluation route.

Inputs
Model or workload, memory need, concurrency, site and service pattern
Useful output
A proportionate route to test, including hosted or no-purchase outcomes
Does not prove
It cannot prove model quality or replace a reference workload test
Open the server sizing tool

Operating cost

Electricity calculator

Turn kW, runtime, utilisation, tariff and cooling overhead into annual energy.

Inputs
Measured or assumed kW, loaded hours, utilisation, tariff and cooling factor
Useful output
Annual energy use and cost with the assumptions visible
Does not prove
GPU TDP alone is not a wall-power measurement
Open the electricity calculator

Whole-life comparison

Five-year TCO

Compare owned capacity with hosted seats using energy, support and facility assumptions.

Inputs
Hardware, finance, energy, support, site costs, hosted seats and useful life
Useful output
A five-year scenario that can show no break-even
Does not prove
Model capability, tax treatment and future pricing need separate evidence
Open the five-year tco

Guided ownership decision

AI ownership calculator

Compare owned, hosted and hybrid AI routes, then apply the operational requirement that cost alone cannot price.

Inputs
Decision priority, term, owned costs, hosted seats, API or cloud spend
Useful output
A cash comparison and next evaluation route
Does not prove
It does not assume local and hosted models are equivalent
Open the ai ownership calculator

Optional capacity

Idle-compute contribution

Stress-test gross marketplace revenue after fees and incremental electricity.

Inputs
Accepted hours, gross rate, marketplace fees, incremental power and utilisation
Useful output
An optional contribution scenario after selected direct costs
Does not prove
It does not guarantee demand, acceptance, availability or income
Open the idle-compute contribution

Crypto scenario model

Mining ROI calculator

Use the preserved specialist application to compare rigs, tokens, electricity, market cycles and exit strategies.

Inputs
Hardware, energy, tokens, price paths, difficulty and exit assumptions
Useful output
Editable mining scenarios with charts and risk context
Does not prove
It is not investment advice and cannot predict realised profitability
Open the mining roi calculator

Conservative defaults

Four values that stay at zero until evidenced

£0

Tax benefit

Eligibility and timing depend on the buyer’s facts and professional advice.

£0

Residual value

Future resale is uncertain and should not be needed to make the base case work.

£0

Marketplace income

Acceptance, rates and available jobs are not guaranteed.

0%

Assumed model equivalence

A local model must pass the representative acceptance set on its own merits.

A spreadsheet is only one part of the operating decision

Remote management, cooling, internal layout and a named service owner sit behind every editable assumption. Supplier images show reference platforms, not a confirmed ordered build.

Use the result

Take the assumptions into a requirements brief

Save the values, dates and source notes you used. The next conversation should challenge the weakest assumption and define the workload test, not treat a calculator output as an order recommendation.
