Why Shaving Costs So Much More Than You Think

The razor handle is cheap on purpose. The money lives in the blades, and that is true whether you buy premium cartridges, double-edge blades for a safety razor, or a monthly subscription. A typical person who shaves a few times a week burns through three to five cartridges a month. At $4 per name-brand three-blade cartridge, that is roughly $192 a year just to keep a fresh edge, and premium five-blade systems near $6 each push the annual tab past $280.

A classic double-edge safety razor flips that math. The handle is a one-time buy, often $25 to $40, and the blades cost about 10 to 15 cents each in bulk. Even running through the same 48 blades a year, your blade spend lands near $6, so total first-year cost including the handle is usually under $50 and every year after is almost nothing.

How We Compare the Three Methods

Cartridge/yr = blades/mo x 12 x price/blade
Safety/yr = handle + (blades/mo x 12 x DE blade price)
Subscription/yr = monthly price x (annual blades / blades shipped)

We take your real blade-swap habit, multiply it out to a full year, and price each path with its own cost structure. The safety razor carries its one-time handle in year one, which is why the gap widens dramatically in year two when that cost disappears.

Where Subscriptions Land

Blade clubs sit between the two extremes. An intro plan at $9 a month for four blades works out to about $108 a year, cheaper than premium cartridges but several times the cost of a safety razor. The catch is the post-intro price bump, so always run the calculator with the rate you will actually pay after month three.

Frequently Asked Questions

How many blades does the average person use per month?
Most people who shave three to five times a week get through three to five cartridges or blades a month, since a single blade comfortably handles five to ten shaves before it starts tugging. Coarse, dense hair dulls a blade faster, so heavy shavers can hit six or more a month while light shavers may use only two.
Is a safety razor really cheaper than cartridges?
Almost always, and it is not close. After the one-time handle cost of $25 to $40, double-edge blades run about 10 to 15 cents each versus $4 to $6 for cartridges. Over a year that gap routinely tops $150, and every subsequent year the safety razor costs just a few dollars in blades.
Do blade subscriptions actually save money?
They save money against premium cartridges but rarely against a safety razor. The bigger risk is the intro-rate trap, where a $9 first plan jumps to $15 or more once the promo ends. Always enter your real ongoing price, not the introductory one, to see the true yearly cost.
How long should one razor blade last?
A quality blade gives five to ten comfortable shaves before it pulls or skips, depending on your hair coarseness and prep. Rinsing thoroughly, drying the blade after each use, and storing it away from a steamy shower all slow corrosion and stretch each blade's life, which directly lowers your yearly cost.

Practical Guide for Razor Cost Calculator

Start by counting your real blade habit rather than guessing. For one full week, note each time you swap to a fresh blade, then multiply to a monthly figure. The difference between three and five blades a month is roughly $96 a year on premium cartridges, so an honest count is the single most important number in this calculator.

Treat the safety razor handle as a one-time investment, not a recurring cost. A well-made handle lasts decades, so its $30 price spreads across years of shaving and effectively rounds to zero after the first year. When you compare year two onward, the safety razor often costs under $10 annually while cartridges keep charging full freight every single month.

Read subscription pricing carefully before locking it into the calculator. Many blade clubs advertise a low intro month then quietly raise the per-shipment price, and some ship more blades than you actually use, padding the bill. Enter the steady-state price you will pay after the promotion and the number of blades you genuinely get through, not the number they push on you.

Quick Checklist

  • Track one week of blade swaps to get an accurate blades-per-month figure.
  • Buy double-edge blades in bulk packs of 100 to hit the lowest per-blade price.
  • Enter your subscription's post-intro price, not the promotional first-month rate.
  • Dry your blade after each shave to extend its life and cut your yearly cost.
