How to calculate this fee, please explain, thank you

I only want to deploy strapi and PostgreSQL database. How much should I pay every month?
Only use the cheapest price point.

Thanks for reaching out, we don’t currently show charge details in the UI when a user is on trial. Here are the charge details for one Strapi server and one Database instance. The estimated cost should now be 10.72.

(7+7) - 7 days trial = 10.72

The previous cost shown in your screenshot reflects the estimated cost for 2 strapi servers and 2 database instances, hope this helps!
