How much should I price my services?

I have been an executive assistant to C Level executives. I basically do everything they ask for and my job description goes beyond whatever was asked but I seriously need help on how to price my services as a freelancer. I work from home and so most of the task the EA doesn't want to spend time on so he can focus on what he does best, his practice.

These are just some of the task I have done before:

Email/Inbox Management (Gmail/Outlook/Teams/Slack, and more) Email Marketing (Newsletters, Email Blast, and more) Calendar Management (Calendly, Outlook Calendar, Google Calendar, and more) Task Management (Evernote, reminders, and more) Project Management (Trello, ASANA, and more) GMB Management (Responding to reviews and more) Social Media Management (Fb, Ig, LinkedIn, Twitter, YouTube, and more) Department Management (I was the whole department lol) Social Media Content Creation (Fb, Ig, LinkedIn, Twitter, YouTube, and more) Social Media Copy Writing (Fb, Ig, LinkedIn, Twitter, YouTube, and more) Blog Writing Data Entry Customer Service (Chat support, Tickets, emails, calls, and more) Appointment Setting Hotel and Travel bookings Chat Support (Socmed and more) Automation (Zapier, Chatbots, and more) SEO and many many more.

Can you please help me determine my hourly worth? I feel like I have been low balling myself for these past years. I am very willing to hop on any tasks given. Thank you!
