Most wedding budgets fail the same way. Someone settles on a total, splits it across categories copied off a spreadsheet, then spends eighteen months quietly discovering the list was wrong. Not because the figures were mad, but because the budget was built out of prices while the wedding is built out of decisions, and decisions carry costs that do not appear on any quote until after you have made them.
Here is a way to build one that survives. It starts somewhere slightly unusual.
The number that matters most is per head
Your total is the number you talk about. Your per-head cost is the number that governs everything. Work it out early, and rework it every time something changes.
The reason is that an enormous share of wedding spending scales directly with the number of people in the room. Catering is priced per person. Drinks are priced per person, whether you buy a package or pay corkage by the bottle. Every place at the wedding breakfast needs a chair, linen, glassware, crockery, a place card and somebody to serve it. Invitations and postage rise in a straight line with the guest list, and even the flowers move, because more guests means more tables means more centrepieces.
Which makes the guest list the fastest lever you have. Taking ten people off it does not remove ten meals. It removes ten meals, ten glasses of fizz on arrival, ten shares of the wine on the table, ten portions of evening food, ten invitations and ten stamps, a table's worth of hire and flowers, and possibly enough space that a cheaper room now works. Reworking a guest list is unglamorous and occasionally awkward. It is still more effective than every clever saving you will read about, put together.
Sort costs by how they behave, not by supplier
Instead of the usual category list, sort every line into one of three types:
- Fixed. The price is the price whether thirty or a hundred and thirty people come. The photographer's day rate. The registrar. Your outfits. The band.
- Per head. Food, drink, evening food, stationery, anything hired per cover.
- Per hour. Venue overtime, bar staff past the contracted finish, extra photography coverage, minibuses, a marquee crew returning on a Sunday rather than a Monday.
This shows you where the flex is. If you are over, per-head and per-hour costs are the ones you can genuinely move. Fixed costs are all-or-nothing: you either book that band or you do not, and shaving them rarely works.
Where the money genuinely concentrates
Venue and catering will almost always be the largest thing in the budget, by a distance, which is why the venue decision effectively sets your budget rather than sitting inside it.
Be careful with the assumption that a blank canvas is cheaper. A field, a village hall or an empty barn transfers cost rather than removing it. A marquee wedding can mean hiring the marquee, flooring, lining, lighting, heating, a generator, loos, a kitchen tent, tables, chairs, crockery, glassware, bar staff, ground protection so cars can park on wet grass, and someone to take the rubbish away. Each is a separate contract with its own delivery charge and VAT position. Dry hire is not a saving. It is a different shape of spend, and sometimes the more expensive shape.
How to read a quote properly
A price advertised as "from £X" is doing a lot of work. It is almost always the cheapest version of that supplier: the quietest month, a Monday or a Wednesday, the lowest guest count they accept, the shortest coverage, no extras. A real price for a real booking, just not for yours.
So put every quote through four questions before you write it down anywhere.
- Is this inclusive of VAT? Some suppliers are VAT-registered and some are not, so two quotes that look comparable may not be. VAT at the standard rate is 20%, which is a lot of money to discover late.
- Is a service charge added? Many venues and caterers add one, applied to a total that already includes food and drink for every guest. Ask whether it is discretionary, and whether it goes on before or after VAT.
- What day, month and year is this price for? Pricing varies enormously by season, by day of the week and by region. A quote given in January for a Saturday in August two years away may be neither.
- What does it assume? Minimum numbers, minimum spend, a set menu rather than a choice, a fixed number of hours. The assumptions are where the price lives.
Then ask the most useful question of the lot: what would take this number up? Good suppliers answer it happily, because they would rather tell you now than argue in the final month.
The costs that never make the first draft
Almost nobody budgets for these. Almost everybody pays them.
- Corkage, if you are bringing your own wine or fizz. Usually charged per bottle, sometimes per bottle opened rather than per bottle drunk.
- Cake cutting fees, charged by some venues for plating and serving a cake you have already paid for.
- Service charge on catering and bar, which can be a meaningful sum on its own.
- Overtime. An hour past the contracted finish can cost venue staff, bar staff, the band and the photographer at once.
- Supplier meals. Photographers, videographers and bands need feeding, and venues charge for it.
- Supplier travel and accommodation, especially for a rural venue or an early start.
- Registrar and notice fees, set by your local authority. Giving notice, the registrar attending an approved venue and the certificates are separate charges.
- Alterations on outfits, which can run to several fittings, plus cleaning and pressing.
- Postage, both ways, including reply cards and thank-you notes.
- Transport at the end of the night, for guests and for you.
- Licences and insurance the venue does not hold, plus wedding insurance itself.
- Trials for hair and makeup, usually charged separately from the day.
None of these is enormous on its own. Collectively they are, and they arrive in the last six weeks, when everything else is already committed.
Hold a contingency, and be strict about it
Keep it as a separate, unallocated pot rather than a line you quietly spend down. The moment it appears inside a category, it has stopped being contingency.
The rule that makes it work: a contingency pays for things that happen to you, not for things you choose. Raid it for a supplier going under and needing replacing at short notice, an unavoidable rain plan, an extra hour on the bar, a rise in guest numbers you could not control, or a final invoice landing above the estimate. Do not raid it for an upgrade you have talked yourself into. That is a budget decision, and it belongs in the budget, where it will make you trade something else away.
Track commitments, not payments
The most common budget shock is not a surprise cost. It is a wedding that looks affordable for a year because only deposits have been paid, then stops looking affordable when the balances all fall due in the same fortnight.
So keep two columns: total contracted, and paid so far. The first is your real position; the second is only cash flow. Note when each balance is due, because most suppliers want clearing several weeks before the day, which is exactly when the small forgotten costs arrive too.
Do that, keep the per-head figure in front of you, and read every quote as a set of assumptions rather than a number. If it helps to keep suppliers, quotes and payment dates in one place rather than four spreadsheets and an inbox, that is what PlanHitch is for.
