Wigan have reported a net profit of £4.3million for the year ending May 31.
It is the first time in six years that the club have turned in a profit, with the sum considerably different to the £7.2million net loss they reported 12 months ago.
The figures cover the 2011-12 season which ended with the Latics in 15th place, with turnover up from £50.5million to £52.6million.
Wigan said on their official website that while salaries remain their biggest expense, they had trimmed them from £39.9million to £37.7million, with £10.4million spent on new players. The sale of Charles N'Zogbia to Aston Villa meant they brought in £7.9million of profit on player sales.
The club's debt, including borrowings and loans from chairman Dave Whelan and his family, reduced to £20.5million from £72.2million, with £48million of it converted into equity.
"The results are once again encouraging and we are very pleased to report a net profit position in a very competitive environment," said chief executive Jonathan Jackson.
"By increasing turnover and controlling costs the club is continuing to progress to a break-even operating position which all football clubs are aspiring to, but many are finding it difficult to achieve."
