Catey Hill of David's Bridal asserts that, as of 2013, the average monetary gift to present to the bride and groom is $150. The Knot says the average amount relatives of the bride or groom spend on a gift is $146, while friends spend an average of $79.

Spending $75 to $100 on a wedding gift is acceptable if the nuptials are for a distant friend or business associate, according to The Knot. If the wedding gift is for a close friend or family member, the cost of the wedding gift should be between $100 and $125.

Presenting the bride and groom with a cash gift is customary in some cultures. In Japan, the bride is presented with red envelopes of money after the tea ceremony. In Spain, every guest who dances with the bride during the traditional dance is expected to present the bride with money.
