Upgrade from Free trial to Pay as you go

Question

If I upgrade my subscription to pay as you go, I hope I will not be charged for the usage over my free trial limit of $200. I noticed that my subscription was deactivated after I crossed the free limit. My question is, if I upgrade now will I be charged for the amount over my free tier limit? I noticed my charges came to $223 (free trial is $200). So if I upgrade, will I have to pay $23?

Hi @Padmavathy Krishnan,

I’m really glad you reached out, and I’m happy to help clarify this for you.

You generally shouldn’t be charged for the extra $23 beyond your $200 free trial credit, as long as your subscription was still under the Azure Free trial and the spending limit hadn’t been removed before that usage occurred.

The amount shown is usage cost measured by Azure, but the Free Trial spending limit is designed to prevent charges beyond the free credit. When the $200 credit is used up, the subscription is disabled/deactivated to help prevent additional charges.

If you upgrade to Pay-As-You-Go, the subscription will be reactivated. You can keep any remaining credit, if any, until the end of the first 30 days, and you may continue using eligible free services within their free limits, including selected services free for 12 months.

You will only be charged for new usage after the upgrade that is not covered by remaining credit or free service limits. You should not be charged for the old $23 trial overage.

One small thing to keep in mind is that once your subscription is upgraded, any paid resources that are still running may begin generating charges. So it’s a good idea to review your active resources and stop or delete anything you no longer need before or right after upgrading.

I hope this helps clear things up and gives you some peace of mind.

Thank you again for taking time.

Answer 2

Upgrading a disabled Azure free trial to a pay-as-you-go subscription does not create retroactive charges for past overage beyond the free $200 credit. Charges start once the subscription is upgraded and re-enabled, and then any non-free or over-limit usage going forward is billed at pay-as-you-go rates.

From the documented behavior:

• With an Azure free account, services are disabled when the $200 credit is exhausted or expires at 30 days.
• After upgrade, resources are re-enabled and you are charged only for usage beyond the free services and quantities from that point onward.
• There is no indication that previously accumulated overage (the amount above $200 that occurred while the subscription was still in free-trial mode) is billed once you upgrade; instead, the free credit simply runs out and the subscription is disabled until you upgrade.

So in the scenario described (metered usage showing $223 total with a $200 free credit), upgrading now results in pay-as-you-go billing for new usage after upgrade. The extra $23 shown as usage over the free credit is not an additional amount that becomes payable upon upgrade; it reflects that the free credit limit was exceeded, which is why the subscription was disabled.

To avoid new charges after upgrading:

1. Before or immediately after upgrading, delete or stop any resources that are not within the 12‑month free services or that exceed their free monthly quantities.
2. After upgrading, monitor costs in the Azure portal under Cost Management + Billing to ensure usage stays within free tiers where applicable.

If no further usage occurs after upgrade, there is no new pay-as-you-go charge to pay.
