How much is IPhone 6s Plus camera replacement?

Hi all.

I have an iPhone 6s Plus which seems to have a defective rear camera. Every picture that I take is blurry and doesn’t zoom in properly.

I’ve tried a lot of the solutions on the Internet including tapping the rear of the phone where the camera is located, doing a hard reset on the phone, and closing out the app. None of them have worked.

Can someone tell me how much it would cost to have the rear camera replaced without AppleCare? I just don’t want to waste my time bringing it in for an appointment if it is more expensive than the phone is actually worth. Thanks in advance.
