The 2018 World Cup has cost Russia billions of dollars to stage and will make FIFA hundreds of millions in profit.
Still, the big numbers that are routine for major sports events are unlikely to set World Cup records.
Russia's official budget of 678 billion rubles ($15.5b) spent on projects for the tournament is less than the estimated US$15 billion ($21.3b) spent by Brazil on the 2014 World Cup.
The budget to meet President Vladimir Putin's pledge to showcase a warmer, more open Russia excludes some transport projects the tournament relies on.
It also looks a bargain compared to the US$51b bill for the 2014 Winter Olympics that extended from Sochi into nearby mountains.
FIFA will top US$6b for the four-year commercial cycle tied to this World Cup, beating its US$5.66b target.
The marquee tournament is overwhelmingly the main source of FIFA income.
That target, however, was conservative compared to US$5.72 billion of overall income booked by FIFA in the Brazilian World Cup period.
Sponsors have been harder to sign since the May 2015 revelation of American and Swiss federal investigations of bribery rocked FIFA and dozens of international soccer leaders.
Here's a look at some of the financial numbers:
Life was relatively good for FIFA and Russia in December 2010 when hosting rights were awarded.
The 2010 World Cup in South Africa ran smoother than many feared, and helped deliver a US$631 million FIFA profit for a four-year period that included a global financial crash. The 2006 World Cup in Germany earned FIFA around US$700m.
Oil prices started a surge beyond US$100 per barrel, fueling Russia for its Olympic and World Cup hosting. By May 2015, oil prices had slumped.
Russian banks and businessmen were hit by international sanctions following the previous year's annexation of Crimea and the rouble value fell.
FIFA's attempts to sell two-tournament sponsorship packages with the 2022 World Cup in Qatar stalled.
"It is complicated, especially in a market where [potential partners] see some crisis around," said Philippe Le Floc'h, the FIFA marketing director who inherited tough sales conditions in late-2016.
The World Cup kicks off with two major gaps in FIFA's sponsorship plan.
FIFA wanted a total of 14 deals in its top-tier "Partner" category, including long-term backers Adidas and Coca-Cola, and second-tier "Sponsor" category. There are just 12. Companies from the United States, Japan, Germany and Britain did not renew after the 2014 World Cup.
Logical replacements, Russian energy giant Gazprom and Qatar Airways, were joined by four Chinese in the 12-sponsor lineup. FIFA's previous leadership revamped the third-tier program for 20 backers — four from each of five global regions — to increase revenue. It did not work outside of Russia and China.
The total one week before kickoff: Four Russian deals, three with state-controlled firms; three Chinese sponsors; none from the Americas or Africa and the Middle East. The overall 34-sponsor program found 19 buyers.
However, the booming broadcast rights market has cushioned FIFA's finances. Deals struck in 2011 with Qatar-owned Al Jazeera Sport, now BeIN, and US broadcasters Fox and Telemundo reaped a big raise over 2010-2014 tournament prices.
FIFA did lose about US$100m of expected income when Italy was eliminated in November before a national TV deal was agreed at a discount.
Ticket sales are below the 3 million mark achieved in South Africa and Brazil. Scaled-back 35,000-capacity stadiums in Yekaterinburg and Kaliningrad are small by modern World Cup standards.
FIFA long predicted a US$100m surplus for a 2015-18 period of spiralling legal costs offset by cost-cutting under CEO-like secretary general Fatma Samoura.
The financial report in March predicted end-of-year reserves climbing back to US$1.8b. It was $1.52b billion in 2014.
FIFA's US$400m fund for 32 competing national federations is US$42m up on 2014.
The winner and runner-up each gets a US$3m raise to pocket US$38m and $28m, respectively. The 16 teams going home after the group phase each earns $8m.
FIFA has budgeted spending US$791m on teams and players — for prize money, club compensation, insurance for players injured on national-team duty, and preparation costs for 32 squads.
Clubs providing players will share US$209m from FIFA.
A daily rate of US$8,530 for the official involvement of 736 players is shared among each club they were registered with in the two previous years.
The next four years
FIFA President Gianni Infantino has made cash promises through December 2022, when the Qatar tournament ends. FIFA's 211 member federations get 20 per cent more, lifting their annual grant to US$1.5m.
Continental governing bodies like UEFA get the same raise, to US$12m annually. The 2022 prize fund goes up 10 per cent to US$440m.
However, that sum was agreed for a 32-team tournament, and it could yet be for 48. FIFA's conservative long-term budget projects US$6.56b income and $6.46b spending in 2019-22.
Smaller stadiums in Qatar means income from ticket and corporate hospitality sales should drop.
World Cup broadcasting rights are ever-more important, providing half of all revenue in the next four years, FIFA said in March.
