I’m a business owner in California. I’m thinking of letting go of one of my employees since I’m not happy with the performance. I would like to understand how we can calculate unemployment benefits we have to pay if the employee does claim unemployment once I let them go. Is there a general rule of thumb or formula that we can use?

For context, this specific employee has been working for me for around 6 months, makes $85K annually, and has around $800/month in company paid insurance benefit.
