Netflix is raising prices.

Given how much it has been spending on content, the move isn’t surprising, but the latest jump — anywhere from 13 to 18 percent depending on the subscription plan — is the biggest increase since Netflix started its streaming service a dozen years ago. That’s going to hurt some consumers.

Many of its users pay for the service even if they don’t consistently watch its content, partly because of its attractive pricing. A bare-bones subscription, for instance, had cost $8 a month. But fee increases at Netflix are inevitable. One of reasons: Netflix burns a lot of cash.

The company’s appetite for content means it has to spend big, resulting in what’s known as negative free cash flow. More money is going out the door than coming in, a difference that Netflix covers by borrowing even more.

“We change pricing from time to time as we continue investing in great entertainment and improving the overall Netflix experience,” the company said in a statement announcing the changes, which apply just to United States customers.
