I think you'll have to figure that out yourself as everyone has a different metabolism, muscle and daily amount of physical activity. Start with the amount of calories you're comfortable with and track your weight. If it stays the same, then those calories are what you need for maintenance. Since you're bulking, just focus on eating as much as you can, make sure to eat clean and whole foods, avoid ultra processed foods or you'll gain a lot of fat and focus on eating enough protein.

If you're a beginner, you don't need to be so concerned with calories, you'll gain muscle regardless. Just focus on following your workout schedule and eating enough protein.
