Cost & ROI

On-Prem vs Cloud: LLM Cost Calculator

At what usage does owning GPUs beat paying per token? Put in your numbers and see the monthly cost, the break-even point, and the three-year picture.

Your workload

million tokens / month

Commercial APIs typically run a few to tens of dollars per million tokens.

Hardware cost (capex): $
Assumptions (advanced)

Power assumes 24/7 operation with a 1.4× datacenter overhead (PUE). Ops overhead covers monitoring, maintenance, and cooling on top of power and amortized hardware.

* A planning estimate, not a quote. On-prem cost is amortized hardware + power + ops and assumes the GPUs can serve your volume; a cloud API scales elastically, while on-prem capacity is capped by your hardware's throughput. Real numbers depend on your models, latency targets, and utilization — which is exactly what a scoping call nails down.
