Taiwan Budget per day

Hello guys I am going to Taiwan this March. I am researching on how much budget per day when I visit Taiwan, do you guys have any idea how much should I put on the budget? i would like to have a cheap bnb, foods (not restaurants), transpo fees, entrance fees (if necessary) and for souvenirs. How much budget would you suggest I save for this trip per day? It would be great if its PHP currency
