How to use the wedding budget calculator
- Enter your total budget and, if you know it, the guest count.
- Adjust the percentages to your priorities. Photography matters more to some couples than flowers — move 5% across and see what it does in money.
- When a real quote arrives, type the amount instead of the percentage. The remaining pot updates instantly.
- Download the CSV or print it for your meetings with vendors.
Typical wedding budget breakdown by percentage
Most planners quote a split close to this: venue and catering 40–50%, photography and video 10–12%, music and entertainment 5–10%, flowers and decor 8–10%, attire and beauty 7–9%, stationery 2–3%, rings 2–3%, cake 2%, transport 2–3%, favours and gifts 2%, and a 5–10% contingency you do not touch until the last month. Where you land depends on the guest count more than anything else: catering is the only line that grows with every chair.
Three mistakes account for most overspending: no contingency line, tracking one number per category instead of estimate → quote → final, and forgetting the small lines (tips, alterations, delivery fees, postage) that never appear on a quote but add up to a full category. Our guide on tracking three numbers, not one covers the method.

FAQ
Is this calculator really free?
Yes. No sign-up, no email, no watermark. It runs entirely in your browser; nothing you type leaves your device.
Will my numbers be there when I come back?
They are saved in this browser on this device. Clearing browser data removes them — download the CSV if you want a copy.
What is the difference from the full Wedding Planner?
The full planner tracks three numbers per line (estimated, quoted, final), links each budget line to a vendor and to payment instalments with due dates, and shows the whole picture on a dashboard next to your guest list and timeline. This page is the first step of that.
