We’ve already seen rumors that iPhone 18 Pro availability may be limited at launch due to the ongoing global memory chip shortage and a new TrendForce report now gives an estimate of how much more expensive the upcoming iPhone 18 Pro might end up being. The iPhone 18 Pro’s bill of materials (BOM) is expected to rise by up to 38% compared to its predecessor. As TrendForce puts it, higher retail prices for the iPhone 18 Pro are “unavoidable” at this point. Previous estimates suggest the baseline 256GB iPhone 18 Pro will cost as much as $1,399. A year ago, the same components accounted for a mere 10% of the iPhone 17 Pro BOM costs.
