The group gave £1.9 billion to good causes in 2012/13, up by 6.9% from last year, bringing the total amount donated over 19 years to £30 billion.
Sales of National Lottery products, such as tickets and scratchcards, were up 2.4% from March 2012, and more than £3.6 billion was paid out in prizes.
A record 365 National Lottery millionaires were created during the year, with 100 in the UK, following the special EuroMillions 100 UK Millionaires Raffle. The total number of National Lottery millionaires made to date is more than 3,300.
Camelot managing director Andy Duncan said: "The National Lottery is all about raising as much money as possible for the Good Causes and creating millions of winners.
"With almost £2 billion delivered for the Good Causes, over £3.6 billion paid out in prizes and 365 new millionaires - that's one every single day - the National Lottery broke all records in 2012/13."
Mr Duncan said: "I think the heart of the success has been maintaining a wide appeal. It has been a lot of people playing a little bit and we have managed to grow for that long on that sense of play.
"We're now up to almost £1.2 million on sales online. We're trying to make sure players can access games when they want to. Looking ahead, we are determined to build on this year's successes by continuing to give our players what they want - anytime, anywhere."
In January, Camelot announced the price of a Lotto line ticket will increase from £1 to £2 this autumn, but the prize for matching three numbers will rise from £10 to £25. The group's profit for 2012/13 is expected to be around £55.2 million, which is 0.8% of total sales.
