Steve Kim, a software engineer in Seattle, said he had been using Mint for three years and was disappointed to find out on TikTok that it was closing. Mr. Kim, 42, said he was looking for alternatives, but would consider Credit Karma.

“I briefly looked it up and it doesn’t look great,” he said. “But I might give it a shot if it’s an easy transfer.”

Intuit said in its statement on Friday that it was “giving Mint users ample time to prepare for this change, before their access to Mint ends.”

Intuit, the owner of widely used financial software applications like TurboTax, bought Mint in 2009 from its founder for $170 million. At the time of the acquisition, Mint, which had been privately held, had 1.5 million users tracking nearly $50 billion in assets and $200 billion in transactions.

Credit Karma helps its 130 million users boost their credit scores and access personalized loan recommendations. Mint users will be able to transfer their linked financial accounts, historical balances and net worth graph over to Credit Karma, and they will be able to continue to track their spending and net worth and view cash flow over time, Intuit said.
