As a result of softer same-store sales and customer traffic levels, the National Restaurant Association’s Restaurant Performance Index (RPI) declined in September. The RPI – a monthly composite index that tracks the health of and outlook for the U.S. restaurant industry – stood at 100.4 in September, down 0.3 percent from August. Despite the decline, September represented the 11th consecutive month that the RPI stood above 100, which signifies continued expansion in the index of key industry indicators.

“Although restaurant operators reported softer same-store sales and customer traffic levels in September, they are somewhat more bullish about sales growth in the months ahead,” said Hudson Riehle, senior vice president of the Research and Knowledge Group for the Association. “Forty-five percent of restaurant operators expect their sales to improve in the next six months, while only 11 percent expect weaker sales.”

The RPI is constructed so that the health of the restaurant industry is measured in relation to a steady-state level of 100. Index values above 100 indicate that key industry indicators are in a period of expansion, while index values below 100 represent a period of contraction for key industry indicators. The Index consists of two components – the Current Situation Index and the Expectations Index.

Despite the softer sales and traffic results, restaurant operators reported an uptick in capital spending activity. Forty-nine percent of operators said they made a capital expenditure for equipment, expansion or remodeling during the last three months, up from 41 percent who reported similarly last month.
