Definition of 'Same-Store Sales'
A statistic used in retail industry analysis that compares the sales of stores that have been open for at least one year. Same-store sales compare revenues earned by a retail chain's established outlets over a certain time period, such as a fiscal quarter or on a seasonal basis, for the current period and the same period in the past (usually the same period of the previous year.) Same-store sales allow investors to determine what portion of new sales has come from sales growth and what portion can be attributed to the opening of new stores.
Same-store sales are also called "S.S.S.," "comps," "comparable store sales," "identical store sales" or "like-store sales."
Investopedia explains 'Same-Store Sales'
Same-store sales figures are expressed as a percentage. For example, retail chain ABC may report same-store sales growth of 4.5% for the current fiscal quarter over last year's. Same-store analysis is important because although new stores may represent growth for a retail chain, a saturation point - where future sales growth is determined by same store sales growth - may eventually occur. Same-store sales are typically published by retail companies on a monthly basis. The figures help analysts differentiate between revenue growth that comes from any new outlets and growth that is a result of improved management and operations at the existing outlets.
