Overview
There are a few key elements to billing, these are the basics.
- Payment information
- Account balance
- Add credits (first deposit and later top-ups)
- Minimum balance threshold
- Recharge amount
Before you can deploy a Massed Compute virtual machine, configure billing:
- Add a payment method with Manage Billing.
- Add credits with Add Credits.
- Set Edit auto-recharge: minimum balance (at least $5) and recharge amount. Credit card auto-charges at the threshold; crypto emails you instead — see Crypto automatic payments.
Once a Virtual Machine is deployed, we will deduct from your account balance every minute. You can spin up multiple Virtual Machines at one time.
How am I charged for usage?
Each virtual machine when you deploy will have a set cost per hour. We sum the cost per hour for all your active virtual machines and divide by 60 to get a cost per minute of active virtual machines. Every minute we do this calculation and debit your account balance based on that math. Sometimes the calculation produces micro cents. The micro cents are carried over as a remainder until the next minute charge.
How am I charged for storage?
If your account uses Persistent Storage, powered by Backblaze (beta), stored data is charged from the same balance every minute at $0.085 per GB-month. Downloads, including reads from the mounted storage on your instance, are free up to 3x your average stored GB each month, then $0.05 per GB, charged daily and not refunded. See Persistent Storage pricing.
