Efficiency = input / output If expenses are $60 and revenue is $80 (perhaps net of interest revenue/expense) the efficiency ratio is 0.75 or 75% (60/80) â meaning that $0.75 are spent for every dollar earned in revenue.
As mentioned above a true antique is more than 100 years old, but some stores value furniture older than 50 years as antique and fine antique dealers will label items antique if they are more than 150 years old. The best way to find out is get the exact age of the piece.
Vintage Jewelry Vintage is a term applied to objects or jewelry of some age. Usually people think of vintage in relation to items with an age of at least 25 years old, but again this is not consistent - it can vary from person to person or dealer to dealer.
