New research from TD Ameritrade shows that according to Millennials, they need an average salary of $80,000 each year “to feel happy.”

But there are large disparities between what different groups want. Those younger than 30 said that this number was an average of $53,500, while those 30 and up said that it was an average of $101,500. But while the minimum average yearly income that men said they needed “to feel happy” was $118,000, this number was $58,500 for women.

Head Solutions Group polled 1,519 Americans between the ages of 21 and 37 for TD Ameritrade.

The least amount of money Millennials need annually “to feel happy”

It’s clear that respondents have different financial requirements for happiness — here’s how they weighed in:

• “Less than $25,000 per year:” 22%
• “$25,000 to $49,999 per year:” 14%
• “$50,000 to $74,999 per year:” 22%
• “$75,000 to $99,999 per year:” 12%
• “$100,000 to $149,999 per year:” 13%
• “$150,000 or more:” 16%

Here’s a bit more context: in 2016, Millennials said they needed an average yearly income of at least $51,000 “to feel happy.”

TD Ameritrade also noted this in the report: “averages exclude top and bottom 5% (i.e. exclude outliers) and have been rounded to the nearest $500.”
