Some affluent Americans plan to boost their holiday donations and spending this year, while few will give less than last year, according to a BMO Private Bank study released Friday.

On average, Americans with a net worth of $1 million or more will give $3,631 to charities this holiday season, with 28 percent donating more than in 2013, 6 percent giving less and the rest donating about the same amount.

In addition, 32 percent will attend charity or fundraising events. At the same time, 71 percent will make cash donations, 68 percent will give clothes, 51 percent will donate household goods, 49 percent will give canned food or gift baskets and 43 percent will volunteer.

“A substantial portion of high-net-worth Americans are increasing their donations of both time and money to charitable causes this holiday season,” says BMO Private Bank President Darrel Hackett. “It’s gratifying to see that, while many are also spending more on gifts for loved ones and other holiday-related costs, giving back still remains a top priority."

The study also found that affluent Americans plan to spend an average of $10,525 on gifts, travel and entertainment during the holidays. Forty-three percent of respondents indicated they intend to spend more than they did in years before the 2008 recession, and just 9 percent indicate they are still planning to spend less.

Survey respondents say they will spend at least $100 per person on their gift list, with 27 percent having plans  to spend $100 to $199, 12 percent $200 to $299, 8 percent $300 to $499, 8 percent $500 to $999, and 6 percent $1,000 or more.

High-net-worth millennials, those between the ages of 18 and 39, stood out as the demographic with the highest proportion of members planning to increase spending on gifts this year. Three quarters say they will spend more this holiday season than last, and 23 percent will be shopping for more than 20 people.
