How to choose
Rotary, foil or safety razor: choosing by beard and by schedule
The three shaving methods fail in different ways. Match one to your beard direction, your morning and the 18-month replacement clock before comparing prices.

Calculators
Each calculator shows its formula, units and assumptions. Nothing is estimated for you in secret.
Cost per use calculator
Turns a price into a cost per use, so a dear item used often can be compared with a cheap one used rarely.
cost per use = (price + consumables over the whole life) / (uses per week x 52 x years)
Routine cost calculator
How long a bottle lasts and what the routine costs per day, from dose and container size.
days per container = container size (ml) / (dose in ml x applications per day); cost per day = price / days per container
Landed cost calculator
What a cross-border order really costs once shipping, duty and tax are added.
landed cost = (item price + shipping) + duty + tax, where duty = item price x duty rate, and tax = (item price + shipping + duty) x tax rate

How this site works
Every figure in a guide is taken from a named source, with the date it was checked. Where a number is an assumption or an example, it says so in the same sentence.
We do not run paid product tests, we do not publish reader reviews, and we do not claim to have handled every product mentioned. Where a claim needs a lab or a long-term test we do not have, the guide says that plainly.
Photographs are free-licence images from Wikimedia Commons or Openverse, credited to the photographer with the licence named. Charts are drawn from the figures printed in the same guide.
This site earns money from advertising and, where disclosed, from affiliate links. That does not change the order of a comparison or the conclusion of a guide.
Some links on this site can earn us a commission. That does not change which product a guide recommends, and it adds nothing to your price. Advertising is not enabled on this site yet. When it is, ads will be labelled and kept visually separate from the guides.
