what means ”LIKE FOR LIKE”

Like for Like is a method of comparing sales or growth for a business over two time periods by ensuring the basis of comparison is the same for both years, so as to avoid comparing apples and oranges. For example, the impact of new stores opened in the later year is excluded from the results of the later year, and the impact of stores closed in the later year is excluded from the results of the prior year. This way the comparison will be more accurate.

Like for Like 是用來比較一間公司營業或利潤增長的計算方法，去令到被比較的兩個時段有相同的根据，而避免有萍果和橙比較的情形出現。方法是將被比較的兩年抽出無從比較的地方。例如新商店要從新的一年扣除，而新一年關閉的商店要從舊一年扣除，然後兩年的比較才會較準確。
