​
Credit system

QuantaCloud uses a prepaid credit model. You load credits into your account and they’re consumed as you use GPU instances. All prices are in USD. There are no contracts or minimum commitments.

​
How charges work

​
GPU deployments

  • You’re charged for the first hour when you deploy. Your balance must cover at least one hour at the offer’s rate.
  • Each further hour is charged when the previous one is used up. Hours count from the moment you deploy, so provisioning time is included once the instance is running.
  • When you stop a deployment, the unused seconds of the current hour are refunded to your balance.
  • If you stop a deployment before it is running, or provisioning fails, the first hour is refunded in full.
  • If your balance can’t cover the next hour, the deployment is terminated and its disk is deleted.
Disk is included in the hourly rate, and there are no egress or ingress charges.
Stopping a deployment terminates the instance and deletes its disk. There are no volumes or snapshots, so copy anything you need off the instance first. Set up auto top-up to avoid unexpected interruptions.

​
Low balance warnings

When your balance falls below $2, you’ll receive a low-balance warning email (at most once every 24 hours) so you can add credits.

​
Payment methods

​
Adding credits

Go to Billing in the sidebar. You can:
  1. Click a quick amount button (10,10, 25, 50,50, 100, 250,250, 500)
  2. Enter a custom amount (minimum 5,maximum5, maximum 25,000)
Pay with a new card via Stripe checkout, or charge a saved card instantly.

​
Saved cards

Under Payment Methods, you can:
  • View all saved payment methods
  • Mark a card as default (used for auto top-up)
  • Add new cards
  • Remove cards (must keep at least one if auto top-up is active)

​
Auto top-up

Keep your balance funded automatically:
  1. Enable Auto Top-Up on the billing page
  2. Set a threshold — when your balance falls below this amount, a top-up is triggered
  3. Set a top-up amount — how much to add each time
When your balance drops below the threshold, the platform charges your default payment method for the top-up amount.
Auto top-up requires at least one saved payment method.

​
Transaction history

The billing page includes a full transaction log with: Export your full transaction history as CSV using the export button.

​
Refunds

When you stop a deployment, the unused seconds of the current hour are automatically refunded to your credit balance. If provisioning fails, or you stop a deployment before it is running, the first hour is refunded in full.

​
What happens when credits run out

There is no grace period, and termination doesn’t wait for your balance to reach 0.Ifthenexthourcostsmorethanwhat′sleft,thedeploymentisterminated,whichcanhappenbeforeyourbalancefallsbelowthe0. If the next hour costs more than what's left, the deployment is terminated, which can happen before your balance falls below the 2 warning threshold. The best way to prevent interruptions is to enable auto top-up.
