March isn’t just for madness. It’s also for money-making.

Several state college basketball coaches are padding their paychecks with bonuses, none more than Michigan State men’s coach Tom Izzo, Michigan men’s coach John Beilein and Central Michigan women’s coach Sue Guevara.

Izzo already has racked up $75,000 in bonuses — $50,000 for winning the Big Ten regular-season championship and $25,000 for making another NCAA Tournament, Michigan State’s 21st consecutive appearance.

Beilein, meanwhile, has tacked another $50,000 on to his pay — $25,000 each for winning the Big Ten tournament and making the NCAA Tournament.

Michigan State (29-4) and Michigan (28-7) will find out Sunday night when and where their NCAA Tournament will start. Both are in position for a 3 seed or better, and each is in contention to start at Little Caesars Arena in Detroit.

The other state team assuredly heading to the NCAAs is Central Michigan women’s team, which beat Buffalo, 96-91, on Saturday afternoon in Cleveland to win the Mid-American Conference tournament championship.

Veteran coach Sue Guevara has accumulated $42,500 in bonuses so far — that represents nearly 18 percent of her base pay — including $15,000 for winning the MAC tournament, $10,000 for making the NCAAs, $7,500 for being named MAC coach of the year, and $5,000 each for winning the MAC West championship, reaching 20 wins (28-4) and finishing with a winning record.

The Chippewas could get as good as an 8 or 7 seed when they learn their NCAA starting point Monday night.

Michigan women's team also is likely headed to the NCAA Tournament. Coach Kim Barnes Arico’s contract information was not immediately available.

As for the other state men’s coaches:

■ Rob Murphy, Eastern Michigan: He would receive $10,000 if the Eagles (21-12) play in the NIT, and $5,000 for each NIT win, or $7,500 if the Eagles play in either the CBI or CIT — as is expected — and $2,500 for each win in either of those tournaments. Of course, he’s already cashed in nicely, as reaching 20 wins earned him an automatic one-year extension, through March 2020. EMU fell to Toledo, 64-63, in the MAC tournament semifinals Friday night.

■ Keno Davis, Central Michigan: He gets $5,000 for having a winning record (19-14), and could get another $5,000 if he reaches 20 wins. The Chippewas are in position for a postseason bid and are bound for the tournament for a game against Fort Wayne, according to CM Life, the student newspaper.

■ Steve Hawkins, Western Michigan: He has earned $2,000 for landing a player on the first-team All-MAC team (Thomas Wilder), and would get $15,000 if his team makes the CBI or CIT. The Broncos (17-15) lost in the first round of the MAC tournament.

■ Greg Kampe, Oakland: He has no specific bonuses in his deal. In a unique setup, his bonuses are doled out after the season, at the discretion of the acting athletic director. The Golden Grizzlies (19-14) have declined two postseason invitations.

■ Bacari Alexander, Detroit Mercy: His contract is private. The Titans finished 8-24.
