GPU cloud cost calculator: hourly, daily, monthly
Pick a GPU and a schedule; the estimate uses the same fixed rates the console bills — every on-demand price is the public marketplace median × 0.70, rounded down. Storage at $0.08/GB/mo and bandwidth at $0.01/GB are the only other lines.

How the estimate is built
Three lines, one rule. The worked example follows whatever you set in the calculator.
Worked example — 1× H100 SXM, on-demand, 24 h × 30 d
- GPU time
- $1.587 × 1 × 720 h$1,142.64
- Storage
- 100 GB × $0.08 × 30/30$8.00
- Bandwidth
- 100 GB × $0.01$1.00
- Total
- per month$1,151.64
The rule behind every GPU price: market median × 0.70, rounded down. This configuration: market median $2.27 × 0.70 → $1.587
GPU time
Price × GPUs × hours. An 8× machine costs exactly 8× one GPU — no multi-GPU premium, no interconnect surcharge.
Storage
Bills on allocated size while the disk exists — including while the instance is stopped. Destroy the disk and the line stops.
Bandwidth
One flat rate in and out, every region. No egress tiers, no inter-zone fees, no surprise at the end of the month.
Billing modes
Interruptible halves the GPU line for jobs that checkpoint. Reserved locks −35% for 3+ months. On-demand is guaranteed until you stop it.
Monthly cost of popular GPUs (730 hours)
What one GPU costs if it never stops — per-second billing means any schedule costs proportionally less.

GPU cost questions
Billing mechanics in depth: billing docs.
How is the monthly GPU cost calculated?
GPU price per hour × number of GPUs × hours per day × days per month, plus storage (allocated GB × $0.08/GB/month, prorated) and bandwidth (GB transferred × $0.01/GB). Billing is actually per second, so the estimate is an upper bound for any schedule you enter.
What does an H100 cost per month?
Running non-stop (730 h), an H100 SXM costs $1,159 on-demand, $579 interruptible or $753 reserved on our sheet — versus about $1,655 at the public marketplace median.
What does an RTX 4090 cost per hour and per month?
$0.262/hr on-demand ($191/month at 730 h) or $0.131/hr interruptible. Eight hours a day for 20 days is $41.92 on-demand.
Are there hidden fees the calculator does not show?
No. GPU time, storage and bandwidth are the entire fee schedule — no setup fee, no minimum, no per-request charges, no support tiers, no multi-GPU premium. Public IPs and port mappings are included.
Can I share or bookmark an estimate?
Yes. Every setting is written to the page address as you change it, so the URL in your browser — or the “Copy estimate link” button — reproduces the exact configuration for a colleague.
