About 94 per cent of the bill for Prince Harry and Meghan Markle’s wedding fell to the British taxpayer, according to the Daily Mail’s accounting, and almost all of that went on security, which is the number that reorders every list of the most expensive royal weddings ever held.
Royal weddings are priced by threat assessment, not by flowers. Once you know that, the rankings stop looking like a competition in taste and start looking like a procurement exercise with a choir.
A note on the figures
Nobody audits these events in public. What follows are the highest-quality published estimates, each attributed to the outlet that ran it, with the original-year figure alongside any inflation adjustment. Where sources disagree, both numbers appear. Visual Capitalist’s July 2026 ranking of history’s costliest weddings, the most recent refresh of the comparison, uses 2026 estimates from Britannica adjusted by the U.S. Consumer Price Index through May 2026, which is the only method that lets a 1956 cathedral be compared with a 2018 chapel. Two of the most famous entries have no verified price at all, and they are included as such. No net worths are given for the families involved: the sourcing behind these costs does not carry verified fortune figures, and this piece does not extrapolate them.
$137m, Dubai, 1979
Sheikh Mohammed bin Rashid Al Maktoum married Sheikha Hind bint Maktoum in 1979, and the event has sat at the top of the royal list ever since. Money Inc puts the cost at $137 million. Luxury Launches puts it nearer $100 million and notes that the month-long celebration set a Guinness World Record for the most expensive wedding. Bollywood Shaadis reports a week of festivities, five days of public holiday declared across the emirate, 20,000 guests, and a stadium built specifically to hold them.
An estimate that swings by $37 million is less a figure than a mood.
A stadium is not a venue hire. It is a capital project with a guest list, and it is the detail that separates this wedding from every European entry below it, where the venue was inherited and the expensive part was keeping people out of it.
$110m, London, 1981
Prince Charles and Lady Diana Spencer married at St Paul’s Cathedral in 1981 at a cost of roughly $48 million at the time, which adjusts to about $110 million in current value, per Databoks citing The Richest. Guinness World Records has the global audience at around 750 million.
The dress cost around $115,000, about $400,000 today, and carried a 25-foot train, still the longest in royal wedding history. It remains the most-recognised garment of the twentieth century and it represents roughly a third of one per cent of the day’s total. The couple divorced in 1996.
$100m+, Abu Dhabi, 1981
The same year, Sheikh Mohammed bin Zayed Al Nahyan married Princess Salama. The List estimates the cost at over $100 million in current money, which by its reckoning exceeded the cost of Prince Charles and Princess Diana’s 1981 wedding, and reports, citing Forbes, that the groom’s parents built a 20,000-seat stadium for the occasion.
Two purpose-built stadiums in two years, for two Gulf weddings, in the era when the region’s oil economies were compounding fastest. The Windsors had a cathedral from 1710 and a policing bill.
$75m, Monaco, 2011
Prince Albert II married Charlene Wittstock, the former South African Olympic swimmer, in a civil ceremony in the Throne Room of the Palace of Monaco on 1 July 2011, followed by a religious ceremony in the Main Courtyard the next day. Today.com reported the wedding was estimated to cost up to $70 million. Infobae put it at $75 million, and itemised the reason: a concert by the Eagles, fireworks, elaborate dinners.
Today.com’s preview of the guest list is the most Monaco sentence in this dossier: France’s richest man, an African prince and an actor who had played James Bond, all converging on a principality smaller than Central Park. The groom was 53.
£33.5m, Windsor, 2018
Prince Harry and Meghan Markle married at St George’s Chapel, Windsor, on 19 May 2018. The Daily Mail reported a total bill of £33.5 million, of which the royals contributed about £2 million, leaving the taxpayer with roughly 94 per cent. Bridebook’s estimate of the security component was £30 million.
Meghan Markle’s gown, by Clare Waight Keller, was reported at £390,000. It dominated the coverage and accounted for roughly one per cent of the cost.
$16m to $64m, Westminster Abbey, 2011
Prince William married Catherine Middleton on 29 April 2011 at Westminster Abbey, and no official cost figure has ever been released. NBC News reported that palace officials told reporters the total bill would be in the six figures. ABC News reported estimates ranging from $16 million to $64 million, with security accounting for the bulk of it. NBC separately reported a major security operation estimated to cost up to $30 million.
A gap of $48 million between the low and high public estimates, for the most photographed day of the decade, is the truest fact on this list. Kate Middleton’s Alexander McQueen gown, with its nine-foot train and handmade lace, was estimated at £355,000 by Hello, and it is the only number anybody remembers.
£168,700, London, 1960
Princess Margaret married Antony Armstrong-Jones on 6 May 1960 in the first royal wedding ever televised, as BBC News reported. The List puts the contemporary cost at around £26,000, which inflation brings to about £168,700, or roughly $212,000.
That is the entire wedding, adjusted, for less than half the price of Meghan Markle’s dress. Television arrived first and the security budget arrived later; the gap between those two dates is where the modern royal wedding economy was invented.
0 verified figures, Monaco 1956 and Amman 2023
Grace Kelly married Prince Rainier III at St Nicholas Cathedral on 18 April 1956, in the union that made Monaco famous to Americans. Hello notes that without a complete breakdown of costs available, it is not known exactly what it cost. Nobody has produced one since. The most cinematic royal wedding of the century has no invoice.
Crown Prince Hussein of Jordan married Rajwa Al Saif at Zahran Palace in Amman on 1 June 2023. Unofficial Royalty reports that the couple were joined on stage by King Abdullah II and Queen Rania, and by Rajwa’s parents, Khaled Al Saif and Azza Al Sudairi, to greet over 1,700 guests. No verified total cost figure for the wedding appears in available public sourcing, and a guest count is not a budget.
Both belong on any honest ranking, marked as unpriced. Lists that assign them numbers are inventing them.
$1.1bn, Mumbai, 2024
The comparator that now tops every version of this ranking is not royal. Visual Capitalist reports that Radhika Merchant and Anant Ambani married in Mumbai in 2024 in a celebration reportedly costing between $641 million and $1.1 billion; Anant’s father, Mukesh Ambani, is the richest man in Asia. Visual Capitalist’s framing is that royal weddings remain among history’s costliest ceremonies, but several billionaire and celebrity weddings now rival them.
At the top of the range, one Mumbai wedding costs roughly eight Dubai 1979s and ten Charles and Dianas, inflation-adjusted. Private money outspends inherited money because private money answers to nobody with a chequebook of its own.
So which was the most expensive, and who actually paid
On documented estimates, the costliest royal wedding remains the 1979 Dubai marriage of Sheikh Mohammed bin Rashid Al Maktoum and Sheikha Hind bint Maktoum, at $100 million to $137 million depending on which outlet you trust, with Abu Dhabi 1981 and Charles and Diana clustered around $110 million in present-day terms. Every one of those figures is an estimate published by a third party, not an account filed by a palace.
As for who paid, the answer differs by jurisdiction and it is the most useful thing on this page. In the Gulf, the families built the stadiums. In Britain, the family pays for the wedding and the state pays for the perimeter. Bridebook put £30 million of the £33.5 million Windsor bill on security.
The gown was the cheap part.
