- Budget in category shares first (venue ~40-50%, food and drink next), and only then in currency — shares survive venue changes, numbers do not.
- Put a written 10-15% contingency line in the budget itself; unwritten buffers get spent twice.
- Track three states per item: estimated, booked, paid. Most blown budgets are just state confusion.
- Vowly Event's budget tracker is part of the free plan — no time limit, unlimited events, next to the guest list it depends on.
Shares before numbers
The first useful budget is percentages, not prices: venue and catering typically claim 40-50% between them, photography and video 10-12%, attire, flowers, music and stationery sharing most of the rest. Write the shares down before you have quotes, because shares are portable — when the venue changes, the frame survives and only the arithmetic reruns. A budget started as fixed numbers, by contrast, collapses at the first real quote and never regains authority.
Then let the guest list drive the per-head lines. Catering, drinks, stationery and favours all scale with attendance, which is why the budget and the guest list belong in the same tool — a budget that cannot see the guest count is guessing at its own biggest variable.
The contingency line and the three states
Give contingency its own visible line — 10-15% — and treat it as spoken for. The quiet failure of wedding budgets is the unwritten buffer: everyone assumes it exists, everyone spends it, nobody tracked it. A written line can be drawn down honestly; an assumed one is spent twice before anyone notices.
Track each item through three states: estimated, booked (a signed number), paid (money gone). Most 'blown' budgets were never overspent — they were misread, with deposits counted twice and balances forgotten. Three columns end the ambiguity, and the running totals become facts rather than moods.
Doing it in Vowly Event, free
The budget tracker is part of Vowly Event's free plan: categories, per-item notes and totals, living beside the guest list, seating plan and timeline it depends on — with no time limit, no card, and for unlimited events, so the engagement and the wedding each keep their own honest ledger. Planning is the free half of the product, permanently.
The paid side (€7.99/month or €39.99/year) is only the guest-facing half — publishing the invitation link, emailed invitations, RSVP details and the guest portal. Your budget never touches it: you could plan the entire wedding's finances in Vowly Event and pay nothing, and we are comfortable saying so because the guests are the part worth paying for.
