Quick answer: Planner-standard percentage splits (40% venue/catering down to a 5% buffer) applied to your total — a sane starting grid before you negotiate anything Free, instant, private — runs entirely in your browser.
How to use
- Enter your total budget in the Total budget field - any currency works, because the amounts come back in the same units you type.
- Press Calculate / Generate (the table also refreshes whenever you edit the field).
- Read the table row by row: each line shows a category, its percentage share, and the amount assigned to it.
- Pressure-test the Venue & catering row first - at 40 percent it is the largest block, so compare it against real quotes from local vendors.
- Use the 5 percent Buffer row as your reserve for overruns, and move money between categories only after you hold written quotes.
- Re-enter a revised total at any time and the whole allocation regenerates instantly, so comparing scenarios costs nothing.
About this tool
Planner-standard percentage splits (40% venue/catering down to a 5% buffer) applied to your total — a sane starting grid before you negotiate anything.
The hardest moment in event planning is deciding how to divide the money before any vendor has sent a quote. A common approach is to start from percentage splits that professional planners use as a default, then argue with reality from there. Enter your total budget in the Total budget field and the tool divides it across eight categories: venue and catering at 40 percent, decor and flowers at 15, photography at 12, attire and beauty at 10, music or entertainment at 8, stationery and gifts at 5, transport and miscellaneous at 5, and a 5 percent reserve called Buffer.
Treat the result as a first draft, not a quote. The venue and catering line is the one to pressure-test first, because in most markets it dominates real costs; if local quotes come in higher, borrow deliberately from the buffer or from low-priority rows rather than overspending silently. The tool applies the same template to every budget size and event type: it does not know your guest count, your city, or whether your event is a wedding, a birthday, or a community fundraiser. Couples, party hosts, school committees, and workplace organizers all use it as a neutral starting grid before negotiations begin.
