Optional capacity scenario

Spare GPU compute contribution calculator.

Start with zero in the base business case. Use this only to stress-test an isolated pilot after the primary workload, platform acceptance and security gates are settled.

Use a measured realised rate, not the highest visible listing.

Monthly contribution before tax and support

£0

  • Rented hours0
  • Gross revenue£0
  • Fees£0
  • Incremental electricity£0

Excludes tax, accounting, support time, hardware wear, downtime, insurance, warranty effects and displaced business work.

Calculation record

See what sits behind the result.

The controls are deliberately editable. Record the values used, the date and the source before relying on an output in a buying decision.

01

Method

  • Rented hours = available hours × realised rented utilisation.
  • Contribution = gross hourly revenue − platform fees − incremental electricity and cooling.
  • Use actual pilot results for realised rate, utilisation and power before treating the figure as evidence.
02

Worked reading

  • The defaults assume 48 rented hours a month at £0.80, not 240 billable hours.
  • The tool then deducts the entered fee and incremental power cost.
  • A zero-utilisation downside case should remain in every purchase decision.
03

Do not infer

  • Admission, demand, rate, uptime and payment are not guaranteed.
  • The result excludes staff time, tax, wear, downtime, insurance and displaced business work.
  • Do not expose private data stores or business networks to third-party tenants.

No earnings promise

Marketplace admission, demand, price and uptime are not guaranteed. Render’s public guidance explicitly cautions against buying hardware in expectation of work. Vast.ai hosts compete on configuration, network, availability and price.

Read the complete marketplace decision gate.

Commercial value starts with a complete cost boundary.

Include installation, energy, support, finance and adviser-confirmed tax treatment. Potential spare-capacity income should remain optional upside.
