Reminder: Your Netflix bill might go up soon

Longtime Netflix subscribers may not realize their monthly bill is about to spike.

Over the past couple years, the video streaming service has inched its monthly subscription price from $7.99 to $9.99, the standard rate for a high-definition plan as of last fall. 

But anyone who was a subscriber before the first price hike -- in May of 2014 -- still pays the $7.99 rate, thanks to Netflix's exemptions for those grandfathered into the plan.

That's about to change. Netflix will begin charging everyone the full $9.99 price next month when the two-year discount deal ends for around 17 million longtime users. 

Netflix subscribers in the UK will start to see the changes take effect later this month, and those who signed up between May of 2014 and last October will pay $8.99 until later this year. 

The price hike may come as news for most of these people, according to a J.P. Morgan note this week, which found that 80% of subscribers surveyed weren't aware of the impending changes.

Details on whether your plan will be among those affected can be accessed under the "Your Account" tab in the upper right-hand corner of the Netflix desktop screen.

While 15% of people surveyed told JP Morgan they were ready to nix their subscription over the price change, UBS Investment Bank's analysts write that off as hot air. The bank guesses only about 3 or 4% will actually follow through.

"It is uncommon for consumers to admit they are willing to pay more for most services," a UBS analyst wrote.
