Paperspace virtual machines (VMs) are available in two subscription types: monthly and hourly. This article will discuss their differences, how to upgrade between them, and what to expect at billing.
All virtual machine subscriptions come with storage: for monthly subscriptions, 50GB is included in the price (more can be added at additional cost - see below for details). For hourly subscriptions, storage is charged in addition to hourly usage.
Storage prices vary by size, starting at 50GB for $5/month. More information on storage-specific pricing can be found here.
Billing runs on the 1st of every month and invoices are available at this time in the Paperspace Console (please allow up to 24 hours for your invoice to fully populate).
Invoices reflect monthly charges for the month ahead; specifically, hourly VM storage fees and monthly VM flat rate fees.
Invoices also reflect hourly VM usage charges for the prior month, as well as add-ons (such as Public IP Addresses, Snapshots, and Templates).
Note: Monthly charges, such as storage, occur at each billing cycle until machines are deactivated
Hourly Machine Subscriptions
Hourly machine subscriptions consist of a flat, monthly subscription fee for storage, plus an hourly rate for the time that the machine is powered on. Hourly VM storage fees cover the cost of maintaining your machine and its data on Paperspace servers. They are charged every month for the lifetime of that machine (i.e. until it is deleted).
Creating an Hourly Machine
When you create an hourly machine your credit card is charged the full storage fee. Your account gets prorated storage fee credit for however many days there were in the month prior to creation. This credit applies on the 1st of the next month, when we run billing, if you owe a balance.
On your invoice, you'll see your storage fee in addition the number of hours in the prior month for which you were billed (at the hourly rate of your chosen GPU instance).
$5/mo storage + $0.51/hr x 10 hours on = $10.10 charged
Note: Your new machine will turn on once it is created.
Deleting an Hourly Machine
When you delete an hourly machine, it will disappear from your Console. Your account immediately gets prorated storage fee credit for however many days in the month are left. This credit goes toward future VMs created in the same billing cycle or your next invoice, whichever comes first.
An Example of Prorated Storage Fee Credit for Hourly VMs
Let's look at a quick example, using the month of February. This happens to be the easiest month for quick human calculation of prorated credit if you were to select $7/mo storage (100GB) because $7/mo / 28 days (in February) = $0.25/day
- CREATE VM midnight (UTC) on February 11th - you get $2.50 applied on next month's invoice ($0.25/day * 10 days into the month)
- DEACTIVATE VM midnight (UTC) on February 19th - you get $2.50 available immediately ($0.25/day * 10 days left in the month)
- You ultimately pay $2 for this VM's storage ($0.25/day * 8 days the machine was active)
Monthly Machine Subscriptions
Monthly VM subscriptions are billed a flat rate, which includes 50GB storage (users may choose to pay for additional storage: prices available here). Monthly subscriptions are a great option for users who need to leave their VMs on all the time, as their flat fee becomes more economical than an hourly subscription after a given number of running hours.
Creating a Monthly Machine
When you create a monthly machine, your credit card is charged the full monthly value of the machine. At the same time, your Paperspace account receives a prorated amount of credit based on when the machine was created. On your first monthly invoice (or the 1st of the subsequent month after creating your monthly VM), this prorated credit will apply. Every month afterwards, as long as the VM is kept on your account, you will pay the full monthly subscription fee.
Deleting a Monthly Machine
When you delete a monthly machine, you are given an option to have the machine remain in your Console for the rest of the month for you to continue using it, or remove the machine from your Console permanently.
Note: monthly VMs are paid for on the 1st of the month, giving users full access to them for the entire month ahead. For this reason, deactivating a monthly VM does not credit your account the way deactivating an hourly VM does.
Upgrading Machine Subscriptions
You can "upgrade" VMs from monthly to hourly (and vice versa). You can also upgrade storage capacity.
Note: once storage capacity has been upgraded, it cannot be downgraded
Standard GPU VMs (Air, Standard, Advanced, and Pro) can be upgraded among themselves. The same is true for C-Class VMs.
Dedicated GPU VMs (P4000, P5000, P6000, and V100) can not be upgraded among themselves.
Upgrades are made in the Console by navigating to a machine's settings page and clicking Upgrade:
Upgrading from Hourly to Monthly
You may want to switch from hourly to monthly if you need to leave it running for a long stretch of time.
Upon upgrading, your billing will be adjusted right away and reflected on next month's as follows:
- Your Paperspace account is debited for any hourly usage up to the moment you upgraded.
- Your Paperspace account is also debited a prorated amount of the monthly subscription fee for however many days remain in the month.
- On the first of the following month, those two debits will apply, and you will also be charged the monthly subscription flat fee for the month ahead.
If you upgraded from hourly to monthly in February, your March 1 invoice will be reflective of your hours used in February until the switch, the monthly subscription charge for the rest of February, and then your flat monthly subscription fee for access in the month of March.
Upgrading from Monthly to Hourly
Important: switching from monthly to hourly does NOT give your account any prorated credit. It is best to avoid doing this until the very end of a given month, provided you are planning to keep the VM into next month but not use it as much.
On your next invoice, you'll be charged the monthly storage fee and any hours used after the upgrade (at the hourly rate for your VM's GPU type).
Upgrading your Storage subscription can be performed in the Console. Your Paperspace account is debited a prorated amount for the remainder of the month for the increase in price between storage rates. Storage cannot be downgraded.
This upgrade will be reflected on the next monthly invoice.
Upgrading Between Machine Types
Air, Standard, Advanced and Pro machines, as well as C-class machines, can be upgraded among themselves.
If you switch a monthly machine, your billing is adjusted so your next invoice will reflect the price difference (as credit or a debit, depending on the change) as explained in an earlier section.
If you switch an hourly machine, your machine will begin billing your hours at the new usage rate right away.
- Your first invoice after creating or upgrading a machine can be a little confusing due to the calculations that go into the change, which are explained above. Feel free to open a support ticket if you need additional clarification.
- Prorated credit for any machine creation, deletion, or upgrade is not transferrable or refundable.
- Features like auto-shutdown are provided to mitigate accidental run time of VMs. If you're relying on this feature, please make sure you meet all criteria listed here. Paperspace does not offer refunds for machine runtime.
