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.
theknot.com →Regional figures from this study are also shown as a static reference table on the calculator page.

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.
