Sales figure - Tradução em português

Gostaria de uma sugestão para tradução de "sales figure", dentro dos seguintes contextos:

"MCDONALD'S says a key sales figure has fallen for the first time in nearly a decade, as it faces the double whammy of a challenging economy abroad and intensifying competition at home."

"The figure is a key metric because it strips out the impact of newly opened and closed locations. It's a snapshot of money spent on food at both company-owned and franchised restaurants and does not reflect corporate revenue."

Obrigada.
