Gross domestic product (GDP) is the monetary value of all the finished goods and services produced within a country's borders in a specific time period.
Recent survey findings from RetailMeNot show that this season's wedding guests plan to spend $195 on a sibling's wedding gift, $159 on a best friend, $63 on a coworker and $45 on an acquaintance. Yet other sources say somewhere in the ballpark of $75-100 for a coworker, and $100-125 for a friend is appropriate.
The average friend of the couple spends $79 on a wedding gift, according to TheKnot.com. 1  Family members spend nearly twice that: $146. The Knot advises wedding guests to consider the following formula: 2  Co-worker or distant family friend or relative: $75-$100. 3  Relative or friend: $100-$125. 4  Close relative or close friend: $100-$150.
