VCI supports pay-as-you-go billing, where fees are charged based on actual instance usage. This billing method is highly flexible. You can use resources on demand, starting and releasing instances at any time. You can select this billing method if you do not need to run VCIs for an extended period.

Fee calculation formula

The formula for calculating the fees of VCI resources is as follows:

Total fees = Instance fees + Image cache fees (if any) + Other cloud resource fees (if any)

The detailed formula for calculating the fees of each VCI resource is as follows:

Fee category	Calculation formula
Instance fees	Instance fees = (Number of vCPUs × vCPU unit price + Memory size × Memory unit price + Number of GPUs × GPU unit price + Temporary storage capacity × Storage unit price) × Instance running duration
Image cache fees	Image cache snapshot storage fees = Snapshot capacity × Unit price × Snapshot storage duration
Other cloud resources fees	The fee calculation formulas vary based on the cloud service type. For details, see specific cloud resource billing documents.
