As of 2013, the cost of using a cartridge razor, in which one keeps the razor but replaces the blades, ranged from about 11 to 27 cents per shave. A double-edged razor cost approximately 7 cents per shave, and a straight razor cost 1 cent per shave. A disposable razor is thus 22 times more expensive to use than a straight razor and anywhere from twice as expensive to only slightly more expensive to use than a cartridge razor.

The life of a disposable razor, however, can be extended by drying the razor with a blow dryer after each use. Another way to extend it is to run it 20 times in each direction up the leg of an old pair of jeans, a procedure which both dries and sharpens the blade.

Although some disposable razors are made from recycled plastic, they are worse for the environment than cartridge, double-edged or straight razors, since most are thrown away rather than recycled. Over 2 billion disposable razors are sold in the United States yearly.
