Calculation formula of reward system

The calculation formula of the reward system is (all expenditure items+tax+management fee)/area-income/area = management fee standard. The so-called contract gratuity system refers to the withdrawal of a certain amount of contract gratuity from the funds that should be charged for property service fees according to the agreed proportion or amount, and then the payment is paid to the relevant property management enterprises, and the rest is used for the relevant expenses agreed in the property service contract. The excess or deficiency is all charged for the relevant property service fees in the way that the owners now enjoy or should bear. Therefore, the calculation formula of the reward system is (all expenditure items+taxes+management fees)/area-income/area = management fee standard.
