The day itself is the easy part. The hard part is the eighteen months of deposits, invoices, and "oh, that costs how much?" moments that lead up to it. Weddings run on a calendar, and the couples who spend the least per guest are almost always the ones who started early — because lead time is the only real discount in this industry.
You're looking at roughly $28,000 all in for a US wedding in 2026. That's not a number you absorb in one month, and it isn't a number you put on a regular credit card either. The play is to match a 15-month interest-free runway to the 12–18 months of bookings ahead of you, so every deposit lands on a card you can actually pay off.
The honest catch: a 0% intro APR is a deadline, not a discount. If $28,000 is still on the card after month 15, the remaining balance starts accruing interest at the standard purchase rate, and the monthly payment jumps fast. The plan only works if the balance is gone before the window closes — so track it monthly and treat the autopay number as non-negotiable.
