Razor Blades: The Real Cost Over a Year

By the BasketLab team · updated 24 July 2026 · how we rank

Nobody thinks much about razor blades until they clock how much they have spent on them. Branded cartridges are one of the great quiet money drains of the bathroom: cheap to start, pricey to keep feeding. This guide does the actual annual maths across cartridge, safety and electric razors, so you can pick the setup that gives you a decent shave without slowly funding a blade empire.

Where the money actually goes

The razor handle is cheap on purpose. The blades are the business model, sold to you again and again at a healthy markup. A pack of branded multi-blade cartridges can cost a startling amount per blade, and if you replace them as often as the packet suggests, the yearly total creeps well past what most people would guess.

So the useful question is not which razor is best, but which system costs least to keep running for the shave quality you are happy with. That is a cost-per-shave calculation, and it changes the picture completely.

The three main systems

There is no single right answer. A safety razor is cheapest per shave but takes a little learning. Electric is easiest for daily use and travel. Cartridges are the convenient default you pay a premium for.

• Cartridge razors: convenient, forgiving, and the most expensive to feed over time. The big names keep blade prices high.
• Safety razors: a single handle and cheap double-edged blades. Higher upfront cost, then blades that cost pennies each. The long-game winner.
• Electric shavers: brands such as Philips, Braun and Wahl. Big upfront cost, but no blades to buy, just occasional foil or head replacements every year or two.

Doing the annual maths

Here is the maths in plain terms. Suppose you shave often enough to change a blade weekly. A cartridge system means roughly 50 branded cartridges a year, and those are the pricey ones. A safety razor uses 50 double-edged blades a year too, but those blades cost a small fraction of the price, often less per blade than a cartridge costs per pack.

Over a single year, the safety razor's cheaper blades usually pay back its dearer handle, and every year after that is close to pure saving. An electric shaver front-loads the cost into the machine, then asks only for a replacement head every year or two, so it also works out well over a few years of daily use.

Making blades last longer

Whatever you use, blades die from moisture and friction more than from cutting. A few habits stretch their life and cut your spend without buying anything.

• Dry the blade: rinse and pat or shake it dry after each shave. Standing water is what dulls and rusts an edge.
• Store it dry: keep it out of the shower spray, not sitting in a puddle on the tray.
• Prep the hair: shave after a warm shower with a decent lather, so the blade works less hard.
• Do not press: let the razor glide; pressing dulls blades and nicks skin.

Where value and own-brand win

Blades are a prime example of own-brand doing the same job for less. Supermarket and value double-edged blades, and budget cartridge compatibles, are frequently made to similar standards as the premium names and cost a fraction. It is worth buying a small mixed pack to find which specific blade suits your face, then bulk-buying that one.

Beyond the blade, the wider shaving aisle is full of rebuys. Candure and Kitsch cover affordable grooming kit and accessories, while NO HAIR CREW handles depilatory options if blades are not your thing. Buy a large tub or bulk pack of the shaving cream and blades you settle on, since price per shave always drops with size.

Which should you buy?

If you want the lowest cost per shave and do not mind a short learning curve, a safety razor is the clear value pick. If you want fuss-free daily shaving, an electric from Philips, Braun or Wahl pays off over a few years and travels well. If you value convenience above all and accept the running cost, cartridges are fine, but at least try own-brand blades before assuming the premium ones are worth it.

Work out your own cost per shave over a year, not the price on the handle. Once you see the annual number, the smart choice usually picks itself, and it is rarely the flashiest packet on the shelf.
