How much do you spend on household per person in a month on average?

How much does your household spend a month after averaging out to each person.

Things like buying groceries and necessities. (Buy detergent, mop, broom and so on) Tabao food.

Please ignore insurance, utilities, transport and housing instalment as I pay them separately.

I am trying to budget household expenses and I am wondering if it is too much or too little if I budget $1250/person purely on household expenses.
