Overview
"Turnover" is a polysemous term used in different fields to denote movement, change, or replacement. Depending on context it can mean business revenue, the rate at which employees leave and are replaced, the loss of possession in sport, a type of pastry, or a technical ratio in finance and science. Understanding the context is essential because the implications and methods of measurement differ widely.
Business and finance
In commercial contexts, "turnover" commonly refers to total sales or revenue generated by a company over a period. In British English this usage is widespread; in other varieties of English the term "revenue" or "sales" may be preferred. Related financial concepts include:
- Inventory turnover — how quickly a company sells and replaces its stock, typically expressed as a ratio linking cost of goods sold to average inventory.
- Asset or receivables turnover — ratios that measure how effectively a business uses assets to produce sales or collects credit extended to customers.
Employment and human resources
In HR, "turnover" (also "staff attrition") denotes the rate at which employees leave an organisation and are replaced. High turnover can indicate dissatisfaction, poor fit, or structural problems; low turnover may suggest stability or limited opportunities. Employers monitor turnover to assess retention, hiring costs, and workforce planning. Simple measures compare the number of separations over a period to the average workforce size.
Sport
In many team sports, a "turnover" means a change in possession caused by an error, interception, fumble, steal, or turnover on downs. It is a key statistic because turnovers often shift momentum and influence outcomes. Different sports record turnovers with sport-specific rules, but the general sense is loss of control that benefits the opposing side.
Culinary and other technical uses
Outside business and sport, "turnover" can also mean a folded pastry filled with fruit, cheese or meat, baked or fried until golden. In science, related terms appear such as "turnover number" in enzymology (a measure of catalytic activity) and "turnover" in ecology or manufacturing to describe replacement rates. Each technical use shares the core idea of change, replacement or throughput.
Distinctions and practical importance
Key distinctions depend on discipline: financial turnover concerns flows of money or goods, HR turnover concerns people flows, and sports turnover concerns possession events. Interpreting turnover correctly requires knowing the unit being counted (dollars, items, people, possessions) and the timeframe. Organisations use turnover metrics for performance benchmarking, risk assessment and operational planning.
