一般来说，家居装修有四大块支出:装修部分(包括厨卫设备);家具部分;家电部分;装饰部分。这四大部分在家装总投资里占有多大的分配比例，现今有很多说法。有的认为装修、厨卫占50%，家具占30%，家用电器及其他占20%;也有的认为 ，装修与家具、家电配套的投资比例应该在1:1或1:2之间。
Generally speaking, household decoration has four major expenditures: decoration part (including kitchen and sanitary equipment); furniture part; household appliances part; decoration part. Nowadays, there are many opinions about the proportion of these four major parts in the total investment of household decoration. Some think that decoration, kitchen and toilet accounted for 50%, furniture accounted for 30%, household appliances and other accounted for 20%; others think that the proportion of investment in decoration and furniture, household appliances should be between 1:1 or 1:2.
其实这些分配比例都只是相对的 ，当今家装行业并没有一个统一、确定的标准。由于职业、个性、喜好等不同，因此消费者对家装投资的分配比例也不可能相同。但是，消费者依然可以把大家比较认可的比例，作为预计家装投资，控制家装 总支出的一个计算依据。
In fact, these allocation ratios are only relative, and there is no unified and definite standard in today's home decoration industry. Because of different occupations, personalities, preferences and so on, it is impossible for consumers to allocate different proportions of household decoration investment. However, consumers can still use the more acceptable proportion as a basis for calculating the expected investment and controlling the total expenditure of household decoration.
