This topic describes the billing methods, billable items, and pricing of NAT Gateway.
Billing method
NAT Gateway supports the pay-as-you-go and subscription billing methods.
Pay-as-you-go: You are charged for the actual usage of each billable item. Fees are deducted after resources are consumed. This billing method is ideal for scenarios in which you cannot accurately predict resource usage.
Subscription resource plans: You must purchase resource plans before you use resources. The fees for resource usage are offset by resource plans.
The subscription billing method is more cost-effective than the pay-as-you-go billing method.
Resource overages are billed based on the pay-as-you-go billing method and included in the bills. We recommend that you purchase resource plans based on the services that you need and the estimated amount of resource usage. For more information, see Purchase a NAT resource plan.
