Managing these kind of numbers requires substantial planning.
And safety will nearly actually be the most important single value.
The Home Office would not remark when Reality Check contacted it, saying revealing policing prices may compromise "national security".
Likewise, once we rang Thames Valley Police, it mentioned: "We aren't going to give you any data I'm afraideven though we know you love numbers."
However, we do know £6.35m was spent by the Metropolitan Police (ie the taxpayer) on safety for Duke and Duchess of Cambridge's wedding.

The value of safety for the wedding shall be met by the taxpayer.
Initially, Thames Valley Police should take up the fee itself.
But the drive shall be eligible to use for particular grant funding from the Home Office after the occasion as a way to declare again among the prices.
Special grant funding is a separate pool of cash forces can apply for in the event that they should police occasions outdoors their normal remit.
As for the remainder of the entire, the Royal Family has mentioned it will likely be paying for the personal components of the wedding.
Every yr the Royal Family will get a chunk of cash from the annual Sovereign Grant, paid instantly by the Treasury.
The grant is calculated on a share of the earnings from the Crown Estate portfolio, which incorporates a lot of London's West End.
This yr it is price £82m.
Some members of the Royal Family profit from extra revenue.
For instance, Prince Charles will get cash from the Duchy of Cornwall property, a portfolio of land, property and monetary investments.
