Keep in mind that this is but one of several expenses you'll have as a wedding guest. If you give a bridal shower gift, you are still expected to give a wedding present. You may also need to pay for travel, apparel, and an engagement present. So use the guideline of allocating 20% of your total gift budget for the shower. For example, if your total budget is $200, you would spend $40 on the bridal shower gift, leaving $160 for the wedding present and engagement present.
