VRAM and GPU cost calculator

How much GPU memory an open-weight model needs, how many cards of each type it takes and what a million output tokens costs on your own rented card, once idle time is counted. Qwen3 32B with FP8 weights and a 32,768-token context needs 54.7 GB: 1 × NVIDIA H100 SXM 80 GB at $3.20 an hour (lowest listed on-demand price, Hyperstack; community-cloud and spot offers are excluded). With one request at a time a million output tokens costs $13.37 if the card is busy every hour you pay for, and $89.16 if it is busy 15% of the time.

Output speed, all requests together: 66.5 tokens per second Calculated (memory-bandwidth estimate, not a measurement). A card that is busy only part of each paid hour makes every token dearer: the cost per million is divided by the busy share.

  • KV cache: Counted on all 64 layers, as the model’s configuration describes them.
  • Price: $3.20 per card-hour, Hyperstack NVIDIA H100 SXM 80 GB (on-demand), as listed in the United States on ; lowest on-demand price of this GPU type in our data, on-demand offers only. Type your own price above to recalculate.

How the estimate works

  1. Weights: parameters × bytes per parameter (2 for 16-bit, 1 for 8-bit, 0.5 for 4-bit), plus 5%.
  2. KV cache: for every token of context and every parallel request the model keeps keys and values: 2 × layers × key-value heads × head size × bytes per value. Models with latent attention (MLA) keep one compressed vector per layer instead: layers × (latent rank + rotary size) × bytes. When every layer uses a sliding window, the context is capped at the window.
  3. Engine overhead: vLLM 2.2 GB + 8% of the weights + 15% of the KV cache; llama.cpp 0.8 GB + 4% of the weights.
  4. More than one card: 0.8 GB per card with NVLink, 1.5 GB per card over PCIe, for communication buffers.
  5. Headroom: the sum is divided by 0.9, so 10% of card memory stays free.
  6. Cards: the smallest of 1, 2, 4 or 8 cards whose memory covers the total.
  7. Speed: each output token reads the active weights from memory once, so one request runs at memory bandwidth × cards × efficiency (vLLM 0.65, llama.cpp 0.55) ÷ weight bytes. Parallel requests raise the total by 1 + 0.62 × (requests − 1), never above the number of requests.
  8. Cost per 1M output tokens: price per card-hour × cards ÷ (tokens per second × 3,600) × 1,000,000 when the card is busy all the time; divided by the busy share of the hour otherwise. Reading the prompt (input tokens) is outside this estimate.

The same formula runs in your browser and in the tables below; the task cost calculator does the same for API prices.

Three open-weight models on each GPU type

Calculated FP8 and BF16 weights, KV cache 16-bit, 32,768-token context, one request at a time, vLLM, every paid hour busy. Per hour: cards × the lowest on-demand price per card-hour of that type (sources in the table of GPU types). Per 1M output tokens with one request is the most expensive way to run a model; more parallel requests in the calculator above lower it, idle hours raise it.
