The wedding budget should be calculated in advance so that there are no unpleasant surprises before the solemn event. It is more convenient to make a complete list of what you will incur costs. On the contrary, you can write an approximate amount of costs. If you don’t know exactly how much it will cost, it’s better to round up. In any case, after compiling such a list, you should set aside part of the funds for unforeseen expenses.
