How much would a tip plasty cost for my nose? Would surgery be the best option for a fix? (photo)

Cost for rhinoplasty including the fee for the surgeon, surgical facility, anesthesia, and post operative care will depend on the city and surgeon. With that said it's best to set up a few consultations with different surgeons and make an informed decision based on their experience and speciality in the field. View their before and after photos to see what the outcome could potentially be. 

The cartilages at the tip of your nose are strong enough that you can see their outline, the little dent between them, and they make the tip look wide, a bit similar to the woman whose short video is posted with this answer.
You should understand that improving a tip like yours requires advanced techniques, techniques that most plastic surgeons cannot handle.  Be sure to read the section in the "Learn more" link on how to stay out of trouble while searching for a rhinoplasty surgeon. You should only have surgery if you are able to make yourself very confident in your surgeon's skills. Read that page very carefully. Most plastic surgeons are quite poor at this operation, and I believe my advice will go a long way toward keeping you safe.I usually make computer morphs when I'm answering a RealSelf question, to show the changes that are possible for your nose with a rhinoplasty. For example see this page:FacialSurgery.com/RealSelf/RealSelf_Morphs.html
But unfortunately the photos you submitted aren't good enough for making morphs. At the *very* bottom of the "Learn more" page is a link to instructions on taking photos that are more comprehensive and useful for online consultations like this, in case you'd like a more complete evaluation.

Hello and thank you for your question. Based on your
photograph, you may benefit from a tip refining rhinoplasty. Cost varies based on geographic region and surgeon expertise.  Make sure you specifically look at
before and after pictures of real patients who have had this surgery performed
by your surgeon and not just a computer animation system.
The most important aspect is to find a surgeon you are comfortable with. I
recommend that you seek consultation with a qualified board-certified plastic
surgeon who can evaluate you in person.
Best wishes and good luck.
