GPU cost estimator
Estimate the monthly cost of renting GPUs by the hour (on-demand vs spot), including storage and egress assumptions.
Instant results Open calculatorLLM VRAM calculator
Work out how much GPU memory a large language model needs for weights, KV cache and activations — and which GPUs can host it.
10 model presets Open calculatorCollected, never invented
A scheduled collector reads providers' own pricing sources daily and stores a dated snapshot. Source type is recorded per row.
Ranked by price, not by payout
Sorting and verdicts are computed from the data. Commissions never influence what you see, and links are never cloaked or redirected.
Works without JavaScript
Tables, FAQs, charts and calculator results are rendered on the server. Turn JS off and nothing breaks.

2026-10-24 Read guideEverything about renting cloud GPUs, affiliate tracking and how we collect pricing data.
No. We do not sell, resell or broker compute and we never take payment. We publish normalised pricing collected from providers' public pages and link you to the provider so you rent directly from them.
A scheduled collector runs every 6 hours (00:00, 06:00, 12:00 and 18:00 UTC). Every table shows the timestamp of the last successful collection. If a source fails, the run is logged and an operational alert is raised rather than silently reusing stale data.
Through the Vast.ai referral programme. If you click a provider link and later pay for compute, the provider may pay us a commission. You never pay more, and commissions never change the prices, ordering or verdicts on this site.
On-demand (also called uninterruptible or secure) means the instance stays yours for as long as you pay. Spot, interruptible or community capacity can be reclaimed by the host and is therefore cheaper. Prices are normalised to a single GPU per hour so different configurations can be compared fairly.
No. Both calculators run entirely in your browser and the results are stored in the URL fragment, so you can bookmark or share a configuration. Nothing is sent to our servers.
Either the provider does not currently list that model, or it was listed but the offer was withdrawn before the last collection. We would rather show a gap than an invented number.
