Driven by stronger same-store sales and customer traffic levels and a more optimistic outlook among restaurant operators, the National Restaurant Association's Restaurant Performance Index (RPI) posted a solid gain in August.  The RPI – a monthly composite index that tracks the health of and outlook for the U.S. restaurant industry – stood at 101.9 in August, up 1.0 percent from July and its first gain in three months. 

In addition, the RPI stood above 100 for the 18th consecutive month, which signifies expansion in the index of key industry indicators.

"The August gain in the RPI was fueled by stronger same-store sales and customer traffic results, aided by continued improving economic conditions," said Hudson Riehle, senior vice president of the Research and Knowledge Group for the Association.  "Looking forward, restaurant operators remain generally optimistic about continued sales growth, while a majority plans to make a capital expenditure in the next six months. However, operators still report food costs and government among top challenges that continue to negatively affect the operating environment."

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.
