Quick note on "cheapest"
This calculator may show canned foam as the lowest cost per shave. That's real for many routines. But cheap doesn't always mean skin-friendly. Many canned foams rely on ingredients that can be drying or irritating, especially if you shave your head frequently or have sensitive skin.
Use the numbers to understand cost, then choose what your skin can tolerate long-term.
Frequently Asked Questions
How does the cost per shave calculator work?
It compares price, product size, and estimated product used per shave to output your cost per shave and monthly spend. You can run it for face shaving or head shaving.
Is shaving soap more economical?
Often, yes. A good shaving soap can last longer per ounce than canned foam or shaving gel, especially when you build lather with control. If you want a deeper breakdown of what tends to perform best, start here: best shaving soap. The real answer still depends on your routine and how much product you use.
Is shaving foam better or gel?
Neither is always better. Foam is fast, but it's easy to overuse. Gel can feel slick and may help some shavers get a closer shave, but results depend on your razor and your skin.
How long does 4 oz of shaving soap last?
It depends on whether you shave face only or head + face, plus how much you load per shave. In wet shaving, 4 oz can last weeks to months. Plug your inputs into the calculator for a tighter estimate.
Should I use shaving foam or soap?
If you want speed, foam is convenient. If you want more control over glide and comfort, shaving soap usually wins, especially for sensitive scalps. If you're deciding between formats, this comparison helps: shaving soap vs cream.
Does the calculator include razor cost and replacement blades?
This calculator focuses on the shaving product itself (soap, foam, gel). Your total cost can change a lot once you add blades, especially for cartridge vs safety razors.
Can shaving soap help with razor burn, razor bumps, or ingrown hairs?
It can help by improving glide and reducing friction, which may reduce razor burn for some people. Bumps and ingrowns still depend on technique, prep, and exfoliation. If you want to understand why some soaps feel more cushioned than others, read about beef tallow soap.
Why does head shaving change cost per shave?
Your scalp is more surface area, so you typically use more product per shave. That's why this tool includes a head shaving option instead of assuming face-only.
