Wedding Spreadsheet Budget: How to Build One for 2027

A wedding spreadsheet budget is the simplest way to keep control of what you spend. Set it up properly and it tells you what you can afford, what you have committed to, and what is still to pay. This guide shows how to build one for a 2027 wedding, with the columns, formulas and UK-specific savings that matter.

It works in Excel, Google Sheets or Numbers. You do not need advanced skills, just a clear structure and the habit of updating it.

What should a wedding spreadsheet budget include?

Start with two tabs: a Budget tab with every line item, and a Summary tab that totals each category.

On the Budget tab, use these columns:

The "Current cost" column is the key. It uses the actual figure if you have one, then the quote, then the estimate. That way your total always reflects the best information you have.

Which formulas do you need?

You only need three or four. These work in both Excel and Google Sheets. Adjust the column letters to match your layout.

• Current cost (column F): =IF(E2<>"",E2,IF(D2<>"",D2,C2))
• Balance due (column H): =F2-G2
• Total committed: =SUM(F:F) (put this in a cell above the table, not inside the column)
• Category total on the Summary tab: =SUMIF(Budget!A:A,A2,Budget!F:F)

On the Summary tab, add a column for your planned allocation and another for the difference. A negative number means that category is over budget. Use conditional formatting to turn those cells red.

How do you split a wedding planning budget between categories?

Begin with your total, then allocate it by category. The split below is a rough starting point rather than a rule. Your priorities will change it.

Venue and catering usually take most of the money, and both rise with guest numbers. If you are squeezed, the guest list is the biggest lever you have.

Why add a contingency line?

Suppliers add extras, numbers shift and prices change between enquiry and invoice. As of October 2026, costs across the wedding industry have been under upward pressure, and prices are likely to keep rising into 2027. A contingency line stops a small overspend turning into a crisis. If you do not use it, you have a head start on the honeymoon.

How do you build the budget step by step?

1. Agree your total. Add what you are saving, what you expect to receive from family, and any date by which you need the money. Be honest about what is certain.
2. Set your top three priorities. Food, photography, venue, music? Put more money there and less elsewhere.
3. Estimate your guest count. Draw up an A-list and a B-list. Many costs are per head.
4. List every cost. Include the ones people forget: venue extras, corkage, cake cutting, alterations, tips, favours, stationery postage, marriage notice fees, and the morning-after breakfast.
5. Get at least three quotes for big items. Record each in the Quote column, with what is and is not included.
6. Record payment dates. Deposits and final balances often land in clusters. A due date column lets you sort by date and spot a heavy month early.
7. Update weekly. Five minutes after each supplier email keeps the figures reliable.

How do you plan a wedding on a budget?

The spreadsheet shows where the money goes. These choices then cut it down:

• Choose a weekday, Friday or Sunday. Many venues charge less than for a Saturday. Ask for their date-based pricing.
• Pick the off-peak months. Winter and early spring are often cheaper than summer. Dates in peak season tend to book up first, so for 2027 weddings in summer, expect limited availability and book as early as you can.
• Trim the guest list. Each guest removed saves their meal, drink, chair, favour and invitation.
• Use an all-inclusive venue. A package price can be easier to manage than hiring everything separately. Check the small print on what it covers.
• Choose seasonal flowers and fewer arrangements. Reuse ceremony flowers at the reception.
• Limit the bar. Offer wine, beer and one signature drink rather than a full open bar.
• Borrow and rent. Attire, decor and signage can often be rented, borrowed or bought second-hand.

These are the budget wedding ideas that make the biggest difference. Small savings on napkins rarely matter next to the guest list and date.

How can you get married cheaply in the UK?

The legal part of a wedding in the UK can cost far less than the celebration. A register office ceremony is usually the lowest-cost route, and you can still hold a party afterwards. Fees for giving notice and for the ceremony vary by area and change over time, so check current costs with your local register office before entering a figure in your spreadsheet.

A small ceremony with close family, followed by a larger informal celebration, is a common way to do a budget wedding without losing the party. Put the legal costs on their own row so they are not forgotten.

What mistakes make a wedding budget go wrong?

• Using estimates as if they were prices. Replace them with quotes as soon as you have them.
• Forgetting per-head costs. If the guest count rises by ten, update every row that depends on it.
• Leaving out supplier extras. Ask about service charges, VAT, travel, overtime and cake cutting.
• Not tracking deposits. Know what is refundable and what is not.
• Spending the contingency early. Treat it as protection, not extra budget.

Should you use a spreadsheet or a planning tool?

A spreadsheet is free, flexible and fully yours, so it suits most couples. The downside is the time spent researching suppliers, comparing quotes and writing emails, which a spreadsheet does not do. If you would rather hand that research off, Wedding Planner by Stridivo finds venues and suppliers, drafts the enquiry emails and scores each option against your budget, location and dates. You can still keep your own spreadsheet alongside it as the master record.
