Cloud GPU Rental Cost Calculator

Estimate monthly cost of renting cloud GPUs.

Quick answer

For the “L4 (~$0.80/hr)” scenario, $576.00/month — 1 GPU(s) x 24h/day at $0.8000/hr. Enter your own numbers below to recompute instantly; the full step-by-step math is shown under the worked example.

Estimate the cost of renting GPUs by the hour for training or self-hosted inference. Use the presets for common GPU types or enter your own rate.

How this is calculated

Monthly cost = price per GPU-hour × number of GPUs × hours per day × 30. Use the presets for common GPU types (L4, A100, H100) or enter your own rate. For inference you can autoscale down; for training you pay for the full run.

Is this a good result? What to do next

Renting only beats a hosted API at high, steady utilization — idle GPUs are pure waste. If your GPUs sit idle much of the day, drop hours/day or reconsider a per-token API.

Typical planning ranges

L4
~$0.80/hr
A100 80GB
~$1.80/hr
H100
~$3.00/hr

Ranges are typical planning figures to sanity-check your result, not authoritative benchmarks. Your numbers will vary with use case, volume, and vendor.

How to improve this number

  • Autoscale inference GPUs to zero when idle.
  • Use spot/preemptible instances for fault-tolerant jobs.
  • Right-size the GPU to the model.

Common mistakes

  • Paying for 24/7 GPUs that sit idle.
  • Comparing rental to API without counting utilization.

When to use a different approach

To find the self-host break-even, use the self-hosted vs API calculator. For a training run, use the model training cost calculator.

Frequently asked questions

Is renting cheaper than the API?+

Only at high, steady utilization. Idle GPUs waste money — compare with our self-hosted vs API calculator.

Do I need GPUs 24/7?+

For inference you can autoscale to zero; for training you pay for the full run. Adjust hours/day accordingly.
