How to build a realistic wedding budget

A wedding budget isn’t one number — it’s a set of trade-offs. The couples who stay on track aren’t the ones who spend the least; they’re the ones who decided early where the money matters to them and where it doesn’t. Start with a total, break it into categories, and protect a buffer.

Start with the total, then divide

Pick a number you’re genuinely comfortable with, including any family contributions. Then split it into categories. These percentages are a widely-used starting point — adjust them to your priorities, because a couple who cares about photography over flowers should shift the weighting.

• Venue & catering — around 45%. This is almost always the largest line.
• Photography & video — about 12%.
• Flowers & décor — roughly 10%.
• Music & entertainment — about 8%.
• Attire & beauty — around 7%.
• Everything else — cake, stationery, favors, transport, coordinator — the remaining ~18%.

Budget per guest, not just in total

Catering, rentals, invitations, and favors all scale with headcount. That means the single most powerful budget lever is the guest list. Trimming twenty guests can save more than cutting any other category — and it’s worth doing before you fall in love with a venue you can’t comfortably fill.

Protect a 5–8% buffer

Something always comes up: a vendor overage, a weather backup, an alteration you didn’t plan for. Set aside 5–8% of your total and don’t touch it until the final weeks. A buffer turns a surprise from a crisis into a shrug.

Track it as you go

A budget you write once and never revisit drifts. Keep a running total as deposits go out, so you always know what’s committed versus what’s left. When the whole plan lives in one place, the budget stays honest — and so does everyone helping you spend it.
