Hi John,
Thanks for getting back to us.
As per this guide, it says below:
"Additionally, bid simulations work with Search Network-only campaigns, Display Network-only campaigns, Shopping campaigns, and Hotel campaigns. For Display Expansion on Search, only information pertaining to the Search Network portion of a campaign is returned."
You will not be able to pull the budget simulation for performance max campaigns. Let us know if you have any further questions.
Regards,
