I've only ever been in 1 wedding ever (when I was 11); FI has been in a lot more, so I pretty much relied on him for the WP gift budget.
Our wedding party is my brother, his 2 sisters and his brother. We figured $100 per for the gifts; so a total of $400.
With us closing on a house here within less than a month left, we did a spreadsheet of our budget with our bills for the house.
We're going to be on a very tight budget until the wedding (very tight, but it'll still work out) - it's our guest list that's killing us (and we already trimmed down as much as we possibly can as FI's family is monstrouly enormous).
I was discussing the budget with my mom (she's contributing as much as she can - not much, but every little bit helps which we are very grateful for!). She seemed really shocked when she found out we were doing $100/person and said that $25 would be sufficient enough.
$25 sounds too little to me, but I also think $100, while it'd be nice if we could do that, might just be slightly too much. I feel like $75 might be a little more doable - but then again, the extra $100 might not really make a difference in our monthly budget for the wedding.
While I realize this will probably be a "do what you can afford" type of thing, but I'm curious as to what others think is an appropriate amount to spend on WP gifts.
