Based on a Razorpedia.com survey, more than 50% of the 186 respondents said they were dissatisfied with the price of their razor and razor blades. Since shaving costs are one of the most commonly cited reasons for switching from cartridge shaving to DE or straight razor shaving, we’ve decided to set the record straight and do the math ourselves.

Shaving with disposable razors is 22x more expensive than using a straight razor, and shaving with a Gillette cartridge razor is 4x more expensive than using a DE razor! Put another way, you can boost your retirement savings by $7,427 by trading in your disposable razors for a straight razor. Or, if you’re one of the mainstream shavers using a Gillette cartridge, you can save $5,082 by trading in your cartridge for a good DE razor.
