Downgrading plan on a web service

I buy a 25$ plan for may web service in the 25th of september and today (27th of september) I decided to downgrade the type of plan into 7$ plan. By the end of my monthly bill. What am I going to pay? The 7$ or the 25$ ? Thank you in advance!

Hi there,

You will pay a prorated amount for the usage of each instance type - you can always see your projected charges at https://dashboard.render.com/billing#unbilled-charges
