How to Split Your Wedding Budget by Category ($30,000 Example)

To split a wedding budget by category, start with one total you can afford, give each category a percentage of it (venue, catering, photography, attire and so on, plus a buffer), and check the percentages add up to 100%. Then compare each real quote with its slice and move money between categories, never past the total.

TL;DR

• Pick the total first. Every category is a share of one number, not a wish list added up afterwards.
• Assign a % to each category and make sure the split adds up to exactly 100%.
• Keep a buffer (the planner's default is 6%) for the costs nobody quotes up front.
• Divide by the guest count to see what the day costs per guest, and how guests drive catering.
• Compare quotes with slices: if one category runs over, take it from another or from the buffer.

Why split a wedding budget by percentage?

Percentages keep every decision tied to the total. If the venue gets 25%, you know before you tour anywhere what "affordable" means for that venue. When the total changes, every slice resizes with it, so you never have to rebuild the list by hand.

A percentage split also makes trade-offs visible. Spending more on photography is fine, as long as you can point to the category it comes from.

Which categories should a wedding budget include?

The AISheetLogic Wedding Budget & Planner starts with 14 categories and a suggested split. It is a starting point, not a rule. Change any percentage to match what matters to you:

Together, venue and catering take 45% in this split, which is why the guest count matters so much (see below). Two spare rows let you add your own categories, such as a honeymoon or welcome drinks.

How does the guest count change the budget?

Divide the total by the number of guests to get a cost per guest. Most catering, bar, rental, stationery and favour costs scale with heads, so adding guests raises these costs while the total budget stays the same. At $30,000, 100 guests works out to $300 per guest; the same $30,000 across 120 guests is $250 per guest.

If the cost per guest feels too low for the venue and menu you want, you have two levers: a shorter guest list or a bigger total. The guest list guide covers the list side.

What does this look like in practice? A worked example

Example: a $30,000 budget for 100 guests, using the default split above, checked against the spreadsheet on 6 November 2026.

Inputs (Setup tab): Total budget $30,000; Guest count (target) 100; the 14 default percentages.

Allocations the sheet calculates:

Quotes so far (Expenses tab inputs) and two paid deposits (Payments tab: $2,000 venue deposit, $1,000 photographer deposit):

Results (Budget tab):

• Expected cost uses the contract price once you have one, and the estimate until then (the florist's $2,600).
• Venue is $300 over and flowers $200 over; catering is $100 under. That leaves a net $400 to find, for example from the $1,800 buffer.
• Catering works out to $59 a guest ($5,900 ÷ 100).
• The Budget tab summary reads "Total budget $30,000 · expected $19,600 · $10,400 still unplanned", and the Dashboard shows $3,000 paid and $16,600 left to pay.

Example figures for illustration only.

How do I do this in the Wedding Budget & Planner?

The Wedding Budget & Planner opens with sample data. Yellow cells are inputs.

1. Setup tab: enter Total budget and Guest count (target). Under Budget categories, edit each Category and its % of budget; the Allocated column fills in. The at-a-glance box says "✓ Budget split adds up to 100%" when the split is right, or tells you how much is left to assign.
2. Expenses tab: one row per thing you pay for: Category, Item (unique name), Vendor, Estimated, then Contract price once booked. The sheet fills Expected cost, Deposits paid, Paid so far, Left to pay and Status (Not paid yet, Partly paid, Paid in full ✓).
3. Payments tab: log each deposit and payment with Due date, Expense item, Type, Amount, and pick ✓ in Paid? when it's paid.
4. Budget tab: each category's Allocated vs Expected cost, Paid so far, Left to pay and Under (+) / over (−), with a summary line under the TOTAL row.
5. Dashboard tab: Expected cost, Paid so far and Left to pay, whether you're under or over the total, plus next payments due.

Frequently asked questions

What percentage of a wedding budget goes to the venue?

There is no fixed rule. The planner's default gives Venue & Rentals 25% and Catering & Bar 20%, 45% together, because those are usually the biggest bookings. If your venue includes catering, combine the two slices into one category. Then compare the quote against the combined allocation instead of two separate ones.

Should a wedding budget include a buffer?

Yes. Deliveries, alterations, extra rentals and tips often turn up after the main quotes are signed. The planner's default puts 6% in Buffer / Miscellaneous ($1,800 on a $30,000 total). When a category runs over, cover it from the buffer first, so the total stays put and you can see how much cushion is left.

What if my percentages don't add up to 100%?

The Setup tab tells you. Under 100%, it shows how much of the split is still to assign. Over 100%, it says to trim a category. Allocated amounts are always total budget × percentage, so a split over 100% plans to spend more than you have. Fix the percentages before you book vendors.

How do I work out cost per guest?

Divide the total budget by the number of guests: $30,000 ÷ 100 = $300 per guest. Do the same with the catering quote to see the per-head meal cost ($5,900 ÷ 100 = $59). If you raise the guest count without raising the total, cost per guest falls. That usually means a cheaper menu or venue.

What happens when a quote comes in over its allocation?

Enter it as the Contract price on the Expenses tab. The Budget tab then shows the category as over (a negative under/over figure). Then decide: lower a different category's percentage, use the buffer, or negotiate. Once the total is set, money moves between categories but the total doesn't grow.
