What shaving really costs

A cartridge seems cheap, but multiplied by hundreds of shaves a year it becomes a noticeable expense. This calculator compares two shaving systems, for example the cartridges you use now and a safety razor, working out the cost per shave and per year, with the handle spread over the years you use it.

It works in any currency: enter the prices you actually pay.

How the calculation works

• Blade cost per shave: the price of one blade or cartridge divided by the number of shaves it lasts.
• Handle cost per shave: the handle price divided by the shaves over all the years you use it.
• Annual cost: cost per shave × shaves per week × 52.

Shaves per blade vary a lot with hair type, skin and technique: use your own real figure.

Systems compared

5 shaves a week, 260 a year; cartridge handles at 10 for 2 years, a safety razor at 30 for 10 years:

The handle matters little: what makes the difference is the blade price divided by the shaves it lasts. Safety razor blades often cost a few cents each.

How much frequency matters

Cartridges against a safety razor, with the data from the previous table:

The reading bands

• No saving: the alternative costs no less than the current system.
• Below 25%: a small difference.
• 25% to 50%: a worthwhile saving.
• 50% to 75%: you save more than half.
• Above 75%: the cost shrinks to a small fraction.

Limits of the calculator

The calculation does not include foam, gel, soap or aftershave, which often cost as much as the blades: add them separately if you like. A safety razor takes some practice, and a new blade must be handled with care. Electric shavers follow a different cost model, made up of the device, replacement heads and electricity.

Frequently asked questions

How much does shaving with cartridges cost?

With 2.50 cartridges lasting 5 shaves and 5 shaves a week, about 135 a year including the handle.

Is a safety razor worth it?

Often yes: with 0.25 blades lasting 4 shaves, the example costs about 19 a year, about 86% less than cartridges.

How many shaves does a blade last?

It depends on hair, skin and technique: often 3 to 7 shaves. Use your own real figure.

Does the handle weigh much on the cost?

Little: spread over hundreds of shaves, even a 30 handle costs a few cents per shave.

What about disposable razors?

They cost less per piece than cartridges but last few shaves: enter them with a handle price of 0.

Does the calculator include foam and aftershave?

No: work them out separately, as they can cost as much as the blades.

Does it work for electric shavers?

Not directly: an electric shaver has a different cost, made up of the device, replacement heads and electricity.

Can I compare two cartridge brands?

Yes: enter the two cartridges as the current system and the alternative.

Does it work in any currency?

Yes. Enter all prices in the same currency.
