Hello everyone. What do you guys aim to make per year and how much do you usually bet per week/month?

My goal is to supplement my income (i have a full time job) with sports betting.

I wish to add about $24,000 a year profit by betting on sports.

I apologize, i am not quite good with calculating ROI and still relatively new to sports betting.

I understand I should flat bet 2% of my roll per day. Could somebody please help me out with the calculations?

How much should I be betting per game if I wish to earn $24,000 per year, $2000 a month, $500 per week?

Let say the average game I bet on is a slight favorite at 1.80, or -120 to win 100. If a win would give me $80,
how many games would I have to play to to make $24,000 per year if I had a win rate of 60% (6/10)? (This is where I got lost with the math).

Thanks for any help.
