You’re also forgetting that cereals contain almost no vitamins or fiber, but avocado does. So, to make up for it, you should eat a salad to your cereals. Then calculate the price again. You will find (I guess) that avocado can compete with cereals+salad.
Well, a multivitamin costs a few cents…
But yes, cereal is certainly less healthy than avocado toast, but it doesn’t really need to be if the rest of your diet makes up for it. Also, there are also breakfast cereals with higher fiber and vitamin content (e.g. most granolas), and oatmeal has 4g fiber in a 140 calorie serving and is cheaper still than most breakfast cereals.
My point here isn’t to decide which is the best option for your breakfast, but to challenge the idea that avocado toast is somehow about the same price as breakfast cereal. There are a lot of options for breakfast that can fit into a balanced diet. The important thing is to find something you like that supports a healthy lifestyle and fits into your budget, and there are a lot of options to get there.
