The National Minimum Wage for 18 to 20-year-olds will also increase by 8.5% to £10.85 per hour, and the rate for 16 and 17-year-olds as well as those on apprenticeships, will increase by 6% to £8 per hour.
Asked if she believed the rates were now too high, Badenoch said: "When I was business secretary I raised the minimum wage and a lot of businesses told me that yes, you've raised it but we can't afford it and we've got to let go of staff."
Questioned whether that meant businesses had been right and she had been wrong, Badenoch replied: "We need to listen to what businesses are saying. It's not government ministers that create jobs, it's business that creates jobs.
"We need to make sure that we set the minimum wage at a good level but we also need to make sure that their other burdens, their business rates, their corporation taxes, all of the things they do - the endless regulation, the employment rights bill: they're just sick and tired of so much happening.
"Let's lighten that burden."
Pressed on whether the minimum wage is currently at the right level, Badenoch said that the government had set it at the rate the Low Pay Commission had said, but businesses needed to be consulted.
"I don't think that we should be raising it any more for example, we've seen that too many businesses can't pay for it.
"You can make the minimum wage £1,000 per hour, if businesses can't pay it none of us are going to have a job."
Asked if she therefore believed that there should be no further increases in the minimum wage, Badenoch said: "Stop government intervention. The government mandating minimum wage increases is not creating jobs. The jobs are disappearing. So that's clearly not the problem."
In a speech titled Getting Britain Working, Badenoch said Labour had got the balance between welfare and business wrong, and had tipped things too far against workers.
Badenoch talked about visiting a cafe owner called Ruth, who burst into tears over how hard it was to run her business when costs for staff and taxes kept going up.
"What last month's budget shows us is that Labour has given up on working people like Ruth," she said.
"While she was struggling millions of people who refuse to work are going to be rewarded.
"We're paying more than the entire population of Norway to sit at home...this is economic suicide."
