The Scottish Rugby Union (SRU) has released figures which show a record turnover of £39.3m.
Murrayfield chief executive Mark Dodson has also revealed their year-end debt is down to £11.2m, the lowest figure for more than a decade.
The SRU also achieved a surplus of £900,000 in the year to 30 April 30 while Scotland, Edinburgh and Glasgow were watched by crowds that totalled more than 500,000.
The financial figures were made public as the SRU hosted its Annual General Meeting at Heriot-Watt University in Edinburgh.
"By attracting more supporters to our game we have encouraged further investment over the past 12 months, no mean feat in challenging financial times," said Dodson.
"We have welcomed a number of new sponsors, while commercial partnerships have been developed.
"We have also agreed the biggest single sponsorship deal in the history of Scottish Rugby, with our new kit partner, Macron."
Dodson also highlighted the importance of an improved performance by the national side during Six Nations as key to their success of the field.
Interim head coach Scott Johnson led the side to joint-third in the championship after they defeated both Italy and Ireland, helping the Scots to achieve their highest position for seven years.
Johnson will be replaced as head coach by Clermont Auvergne boss Vern Cotter in June 2014.
