Philips OneBlade True Cost Calculator – How Much Do the Blades Really Cost?
Calculate the real yearly and per-shave cost of Philips OneBlade replacement blades based on how long they last for you — not the official 4-month claim.
Philips says one OneBlade lasts up to 4 months (based on two full shaves per week).
In reality, your results depend on how often you shave, how thick your hair is, and whether you use the same blade for face and body.
This calculator lets you see the actual cost of ownership based on your own numbers.
OneBlade True Cost Calculator
Philips claims ~4 months at 2 shaves/week. Adjust for your real usage.
How to use this calculator
- Blade Pack Price → What you actually pay for a pack of blades.
- Blades in Pack → Usually 1, 2 or 3.
- One Blade Lasts → How many months you personally get from one blade.
- Shaves per Week → Your real usage frequency.
The calculator shows both the yearly cost and the cost per shave so you can compare it fairly with other shaving methods.
Why the Official 4-Month Claim Varies So Much
Philips bases the 4-month figure on two full shaves per week.
Real-world lifespan changes with:
- Daily or near-daily shaving (faster wear)
- Coarse or dense facial hair
- Using one blade for both face and body
- How thoroughly you clean the blade after each use
Many users report 2–4 months depending on their routine. Adjust the lifespan slider to match your experience for a more accurate picture.
Frequently Asked Questions
