Monthly cost
$704.64 × 30
= $21139.20
How it works
Monthly cloud GPU cost is the product of hourly rate, hours of daily utilization, GPU count, and days in the billing period. Running GPUs 24/7 (hoursPerDay = 24) reflects always-on training clusters, while lower daily hours model bursty or scheduled workloads that spin down during idle periods to save cost.
Formula
monthly_cost = hourly_rate × hours_per_day × gpu_count × days_per_month
- hourly_rate
- GPU hourly rental rate
- hours_per_day
- Hours of daily GPU use
- gpu_count
- Number of GPUs
- days_per_month
- Days in the billing period
Frequently Asked Questions
How much can I save by not running GPUs 24/7?
Reducing daily usage from 24 to, say, 10 hours cuts cost proportionally — about 58% savings — assuming your workload can tolerate scheduled downtime.
Do spot/preemptible instances change this math?
Spot instances offer lower hourly rates (often 50-70% off) in exchange for the risk of interruption; substitute a lower gpuTypeRate to model spot pricing.
Is this the same as the GPU Cost Estimator?
This calculator adds a daily-hours and days-per-month dimension for monthly budgeting; the GPU Cost Estimator compares GPU types directly against a fixed hours total.
