@johnero On paper it sounds like it can work but truth is that things arenโt as rigid in reality so some months itโs fine and other months itโs not. I buy only the idea of having a fixed rent funds and monthly savings , emergency funds.
Looks solid on paper , the budget canโt be this rigid every month. Fairs a fixed amount for rent and feeding can be set but even the savings would be further divided to savings and then emergency funds
