The Queen is to receive an 8% increase in income from public funds, after the Crown Estate's profits rose by 拢24m.
The Sovereign Grant, which pays for the salaries of her household, official travel and upkeep of palaces, is to increase by more than 拢6m in 2018/19.
It comes as accounts revealed the Queen's official net expenditure last year increased by 拢2m, to almost 拢42m.
Sir Alan Reid, Keeper of the Privy Purse, said the Queen represented "excellent value for money".
He said: "When you look at these accounts, the bottom line is the Sovereign Grant last year equated to 65p per person, per annum, in the United Kingdom.
"That's the price of a first class stamp.
"Consider that against what the Queen does and represents for this country, I believe it represents excellent value for money."
