Wedding budget breakdown: a worked example with deposits and due dates

Last updated: 15 October 2026 · By Quicksloth

Percentages tell you how a wedding budget is usually split. They don't tell you what happens when the quotes come in, how much you have already paid, or how much cash you need in the last month. Here is one budget followed from start to finish: $25,000, 70 guests, 31 lines, four vendors booked with a deposit.

Short version: the shares suggest an amount for every line. Real quotes move some lines up and others down; in this example the plan ends up $855 over, and $9,180 of balances fall due in the last four weeks before the wedding.

This is a made-up example (the same one that comes filled in with our wedding planner). Vendor names are invented and your prices will be different.

Step 1: split the total with typical shares

Start from one number, the total you can spend, and give each part of the wedding a share of it. Published guides agree roughly on the shares. Joy's wedding budget breakdown by percentage (updated 9 July 2026, read 15 October 2026) gives these ranges; next to them, the default shares we use in our spreadsheet. Ours are a starting point inside or close to published ranges, not a rule.

In the spreadsheet these parts are 31 lines (venue hire, catering, drinks and bar, photographer, videographer, two outfits, hair and makeup, and so on). Each line's suggested amount is its share × the total, rounded to the dollar: catering is 20% × $25,000 = $5,000, the photographer 8% × $25,000 = $2,000. Change a share if your priorities are different; the shares just need to add up to 100%.

How does $25,000 compare? The Knot's 2026 Real Weddings Study (10,474 US couples married in 2025; page updated 24 June 2026, read 15 October 2026) puts the average wedding at $34,200, with 117 guests and $292 per guest. Joy's average wedding cost page (updated 30 June 2026, read 15 October 2026) quotes The Wedding Report at $30,119 for 2025. Averages are pulled up by big weddings; the shares work the same way on any total.

Step 2: turn the guest lines into a price per head

Caterers quote per person, so the lines that grow with the guest count are worth reading per head: suggested amount ÷ 70 guests.

Now a quote can be checked in one look. A caterer asking $84 a head for 70 guests ($5,880) is about $12.60 a head, or $880 in total, above what the budget suggests. That's not a reason to say no; it's the number to find somewhere else.

Step 3: write your estimates and the real quotes

Each line has three of your own numbers: Estimated (what you expect to pay), Actual (the signed price, once you book) and Paid (what has left your account). Still to pay is Actual − Paid. Here are the lines this couple has touched so far; the other 17 lines are still empty.

Two things to notice. The Estimated total ($20,650) looks comfortably under $25,000 only because 17 lines are still blank. And skipping the videographer is written as $0, not left empty: an empty line still counts at its suggested amount (next step), a zero says "we decided".

Step 4: over or under?

To know where you stand, each line counts once, with the best number you have: the Actual if you've booked, otherwise your Estimated, otherwise the Suggested amount. That way a line you haven't thought about yet doesn't count as free.

Where the $855 comes from, against the suggested amounts: catering +$880, outfit +$350, photographer +$200, rings +$190, cake +$100, centerpieces +$50, invitations +$35; minus the videographer −$750, the DJ −$150 and the bouquets −$50. Total: +$1,805 − $950 = +$855.

The planned total also includes the whole $1,250 contingency line. So the plan is over on paper, but if the contingency is never touched the wedding still costs $24,605, under the $25,000. The useful reading is: the contingency is already being used up by the catering quote. Time to trim another line before more quotes come in.

Step 5: deposits paid and balances due

A budget says how much; a vendor list says when. Each booked vendor has a quote, a deposit paid on booking, and a balance with a due date (here written as weeks before the wedding; your contracts give the real dates).

Three more things are already paid in full (outfit $1,350, rings $940, invitations $285: $2,575), so the $7,075 paid so far is $4,500 of deposits plus $2,575. The florist has sent a $1,250 quote but isn't booked yet: a quote is not a balance, so it isn't counted here until it's signed.

Now line the balances up by due date:

• 4 weeks before: $2,500 (venue)
• 2 weeks before: $5,180 (catering $4,380 + DJ $800)
• 1 week before: $1,500 (photographer)

That's $9,180 in the last four weeks, more than a third of the whole budget, and it doesn't yet include the drinks, the florist or the cake. The balances on the vendor list and "still to pay" in the budget agree ($9,180), which is a good check that nothing has been missed.

What this example shows

• Count blank lines at their suggested amount. Otherwise the budget looks fine until the last month.
• Write $0 for what you skip. It frees that money for the lines that came in high.
• Compare per head. A catering quote of $5,880 says little; $84 a head against a suggested $71 says a lot.
• Keep the contingency line, and watch it. When the plan goes over, the contingency is what's being spent.
• Plan the cash for the last month. Deposits are spread out; balances bunch up just before the wedding.

Do it with your own numbers

Our Simple Wedding Planner does every step on this page: type your total budget and your guest count, and the Budget tab fills in the 31 lines with suggested amounts and the per-guest column; Estimated, Actual and Paid are yours to type, and Still to pay and Over / under count themselves. The Vendors tab keeps quote, deposit, balance and balance due date for each vendor and shows the days to the next balance due. This page's example is the one that comes filled in with the file. It works in Excel and Google Sheets and is coming soon to our Etsy shop.
