An average wedding will spend 50% of their budget on the reception. This includes food, drinks, and venue. 10% of the budget is spent on the attire. This includes bridesmaid dresses, suites for the groomsmen, as well as the bridal gown. Another 10% is spent on the decorations, and another 10% on music. Plan to spend another 10% on a photographer or a videographer, and the rest for miscellaneous charges. This of course is not set in stone. Your wedding might be much different then this. But when setting up your wedding budget worksheet this is a good place to start.
I've found that when creating a budgeting worksheet the best way to start is with a set up like this; _ Firstly, place your pay dates along the top (shown from A1 to G1). These can be weekly, fortnightly or monthly or any period that you normally work from. _ Then list out each income source and the amounts you receive from them. For irregular payments such as Christmas bonuses etc set up a row specifically for this and maybe name it "Other Income".
