The most common wedding budget mistakes, from setting the budget after booking the venue to forgetting tax, tips and alterations, and how to avoid each one.
The most common wedding budget mistakes are booking before you've set a total, building the guest list after the budget instead of alongside it, forgetting costs that aren't on the headline quote (tax, service charges, tips, alterations, delivery), leaving no buffer, and spending to impress guests rather than on what you'll value. They're common: in LendingTree's 2025 survey of US newlyweds, about a third said they went over their wedding budget.
LendingTree's 2025 survey of 1,050 US newlyweds, conducted by QuestionPro in March 2025, found:
A venue deposit made on a good feeling sets the scale of everything else. Agree the total with everyone contributing first, in writing if family is paying (see what if your parents are paying for the wedding), then book.
Agree the total and who's contributing. Rank your priorities. Set a guest count that fits. Allocate by category, keeping a buffer. Get all-in quotes and compare like with like. Track every payment and due date. Review the budget whenever the guest count changes.
Setting the guest count and venue before agreeing a total budget. Those two decisions shape most of your other costs.
There's no official figure. Keep an unallocated amount you'd be comfortable spending on surprises, and don't touch it for upgrades.
In LendingTree's 2025 survey of 1,050 US newlyweds, 32% said they went over their budget.
It's a personal decision, but 67% of newlyweds in the same survey took on debt for their wedding. If you borrow, know the interest rate and how you'll repay it before the wedding, not after.
