The new deal will also include Moneysupermarket's new Debt Solutions product, which guides consumers struggling with debt through the options available to them.
Mark Donnan, business development manager at Moneysupermarket.com, said: "MSN is a major partner win for us. It is an extremely well respected and trusted, consumer focused website, committed to providing insightful editorial opinions, news and reviews.
"The two companies share many of the same customer values and we look forward to working with MSN to deliver accessible and transparent information and advice to users."
The price comparison site will also be launching a weekly column in July to help consumers better understand the financial market and provide personal finance tips. The column will be written by Moneysupermarket.com's site editor, Clare Francis, who will also lead a series of regular video blogs.
Phil Coxon, head of partnerships at Microsoft Advertising, said: "Moneysupermarket.com has great consumer insight into the market and provides users with a wide choice of offers online.
"With the current economic situation increasing cost pressures on consumers, people are much more concerned with how they spend their money and it is important for them to have a trustworthy brand to turn to for advice."
