Intuit Inc. is adding a home valuation feature to its Mint.com financial management site through a partnership it announced Wednesday with Zillow Inc.

Mint, which is free to consumers, already allows users to get a sense of their financial standing by linking bank accounts and subtracting debts from savings.

Adding Zillow's home value algorithm, Zestimate, to the Mint site should help consumers make better financial decisions, Intuit said.

"Because a home is usually a person's largest asset, it makes perfect sense for us to integrate with Zillow, to help our users track their home's Zestimate in their Mint account," Aaron Patzer, the vice president and general manager of Intuit's personal finance group, said in a press release.

Intuit also said Wednesday that it is reaffirming its financial guidance for the 2011 fiscal year, which ends July 31.

The company expects overall revenue to increase 8% to 11% in 2011, and earnings of $980 million to $1.02 billion. Per-share earnings should come in between 1.88 and $1.95

Revenue in Intuit's financial services unit should increase by 4% to 7%.
