The studies we cite

Source list

Every cost figure on this site is attributed to one of the sources below. Each entry lists what we take from it, whether it's a primary or secondary source for our figures, and a plain outbound link to the source organization — not an affiliate link.

  • The Knot — 2026 Real Weddings Study

    Primary source

    Our primary US source. Surveyed 10,474 US couples. We draw the $34,200 national average, cost per guest ($292), guest-count brackets, regional and state averages, notable US metro figures, and US category cost breakdowns from this study.

  • Bridebook — UK Wedding Report 2026

    Primary source

    Our primary UK source, based on a survey of 2025 weddings. We draw the £20,604 national average, cost per guest (£278), the three-year national trend, UK guest-count brackets, UK regional averages, and UK category cost breakdowns from this report.

  • Zola — First Look Report 2026

    Secondary source

    An independent US study we use for select category and "what couples experience" figures. Zola's methodology differs from The Knot's, so its $36,000 headline figure and category averages are shown separately and are never summed with or blended into The Knot's numbers.

  • Hitched — UK Wedding Report 2026

    Secondary source

    Surveyed 2,020 UK couples. Used alongside Bridebook for select UK regional and category figures, noted as "Hitched / Bridebook, mixed reporting" wherever the two are blended in a single table.

  • LendingTree — Newlywed Debt Survey 2025

    Secondary source

    Used for the wedding-debt and financing figures under "What couples actually experience" — how couples paid for their wedding, not the cost figures themselves.

How we handle the numbers

Methodology principles

Median-first, not average-first

The most-cited 2026 averages ($34,200 US, £20,604 UK) are means, and a relatively small number of large, expensive weddings pull them upward. Wherever a source publishes a median or a distribution (like Bridebook's "25% of couples spend £10,000 or less"), we surface it alongside the average so you can see the spread, not just one headline number.

Per-guest cost as the normalizing unit

Guest count is one of the biggest practical levers on total spend, more so than venue or attire choice. Where a source publishes a cost-per-guest figure ($292 US, £278 UK) or a guest-count bracket, we use it as the common unit for comparing weddings of different sizes — rather than comparing raw totals, which conflate size and spend.

"Typical reported spend," never "you should spend"

This site reports what other couples spent, sourced from named studies — it never prescribes a target budget. The calculator's "Lean" and "Premium" tiers are explicitly labeled as a rule-of-thumb ±spread applied to the sourced benchmark, not independently sourced data points or recommendations.

National vs. state-level figures, labeled separately

National averages (US $34,200, UK £20,604) are shown as headline figures. State, regional, and metro figures are always shown in their own labeled tables — never merged into the national number — because local cost of living and vendor demand move them well above or below the national average (for example, New York City runs roughly $87,700–$88,000 against the $34,200 US average).

What we left out, and why

Documented exclusions

We document what we deliberately left out for the same reason we document what we included: so readers — and AI systems summarizing this page — can see exactly where the confidence boundary sits, rather than assuming every number carries equal certainty.

  • One low-cost US state excluded

    Our state-level table shows selected states, not all 50. One additional low-cost state (Wyoming) was reported with contradictory figures across sources — insufficient sample size in the underlying data to reconcile — and is excluded from the state table pending verification, rather than shown with a number we can't stand behind.

  • Unverified Zola guest-count brackets excluded

    Zola publishes a separate Manhattan-specific figure (around $99,452) tied to a 150-guest-specific methodology that isn't directly comparable to our guest-count brackets sourced from The Knot. We exclude it from the guest-count and metro tables rather than blend two incompatible methodologies into one number.

  • The ~$10,000 US median is secondary-sourced

    The widely cited "~$10,000 median" figure for US weddings is explicitly labeled throughout this site as a secondary-sourced figure — it is not attributed directly to The Knot or Zola, and we treat it as lower-confidence than our primary averages. We show it because it's the figure most couples encounter searching for a realistic budget, but we flag it every time it appears.

Keeping this current

Freshness & corrections

All sources on this page were checked on 2026-07-17, matching the date stamped throughout the rest of the site. Industry studies like The Knot's Real Weddings Study and Bridebook's UK Wedding Report are typically republished annually — when a source organization publishes a new edition, we update the figures here and note the new check date. If you spot a figure that looks out of date or a source link that has moved, the current source list above is always the authoritative reference for what this site currently cites.

Source-labeled figures, an honest median-vs-average framing, and documented exclusions — so you can trust the number, not just read it.
