Afraid of overspending on holiday gifts? Set a budget. We'll show you how.

Perhaps no transaction is as fraught with emotion and stress as the purchase of a holiday gift.

Will they like it? Will they use it? Will it end up in the back of a closet, or back on the shelves of the store whence it came? And what if the recipient reciprocates with a much better gift?

With the psychological stakes so high at the holidays, many of us spend beyond our gift-giving means. This season, nearly 7 in 10 shoppers expect to overspend, according to a September survey of 2,408 Americans conducted by YouGov for CNET Money.

The obvious solution: Set a gift-giving budget, and stick to it. But where to start?

In the heat of holiday shopping, no amount of spending seems quite enough. There’s no universal standard for what to spend on a gift for a child, or a spouse, or a houseload of in-laws.

Happily, several sites offer holiday budget calculators: A starting point, at least, for planning your spending.

A simple budget for holiday gifts? How about 1.5% of your annual salary

Clearpoint, the credit-counseling nonprofit, suggests a simple target for holiday budgeting: Plan to spend 1.5% of your annual income. For a family that earns $75,000 a year, that works out to $1,125. Sliding buttons allow you to allocate shares of the total to gifts, parties, travel, donations and food. Once your gift budget is set, the planner helps you populate a gift list.

You’ll need an actual calculator to run the numbers in Wired magazine’s holiday gift calculator.

In the Wired model, you start by setting a total gift budget. Then, you list every gift recipient. And then, you assign each one “an importance rank,” from 1 (low) to 10 (high). Obviously, the resulting list is not a document you’d want to see falling into the wrong hands.

A few quick calculations yield a unit of gift spending: say, $13.50. Multiply that figure by each recipient’s rank to learn how much you should spend. Your spouse, with a rank of 10, gets a gift worth $135. Your least-loved nephew, with a rank of 1, gets something priced at $13.50.

WalletHub, the personal finance site, offers a free, customized holiday budget to anyone who creates an account.

Odysseas Papadimitriou, the WalletHub CEO, didn’t give up the math behind the calculator, but he said it’s tailored to tell every consumer how much they can safely budget without adding to their financial burden.

“It’s very, very important to go into the holiday season with a budget, and the budget needs to reflect what you can spend without going into debt,” Papadimitriou said.

Overspend on lavish gifts, he said, and “you’re giving the wrong message to your family, and to your kids, and you’re teaching them the wrong set of priorities.”
