The average cost to have plastic surgery performed on your buttocks is around $4,000.00 for the lowest cost and can be as high as $5,200.00 depending on what exactly the plastic surgeon is doing when they're performing plastic surgery on your buttocks.
A butt lift costs the highest which is around $5,000.00 and for fat grafting and buttock augmentation it's usually on the lower end of $4,000.00 but it can vary depending on the plastic surgeons experience and the location as some plastic surgeons may charge more or less.
Don't always go for the cheapest price of plastic surgery though because you may get worse results than paying a higher price for the buttock surgery from a more experienced plastic surgeon.
