Full-year profit is now estimated at 3.4 billion euros, compared with a previous forecast of 3.2 billion. The target for 2030 is 5.9 billion euros in profit.
The cuts and forecast increase are being presented at the same time as Italy's UniCredit has launched a bid to buy Commerzbank, whose board has rejected the proposals.
Shares in Commerzbank, which has already initiated a reduction package that will eliminate 3,900 jobs, fell 1 percent after the announcement.
Commerzbank has around 38,000 employees ahead of the staff cuts.
