New tool: Perfume Value Calculator — figure out how long your bottle last
Built something for the community 👇
Ever stood in front of a 30ml vs 50ml decision and tried to do the math in your head? Or wondered if that $300 niche bottle is actually worse value per-wear than a $90 designer you spray twice as much of?
Made a free calculator that works it out for you:
**Bottle size** — 10ml to 100ml, or enter your own
**Sprays per day** — 1 to 30 (most people land at 4–8)
**Nozzle type** — fine, standard, or heavy atomiser (this matters a lot)
**Bottle price** — optional, but unlocks cost-per-day
**Output:** how many days/months your bottle realistically lasts, and what every wear is costing you.

A few things I’d love feedback on:
•Is 30 sprays/day too high a ceiling? Felt right for the heavy-projection crowd but curious.
•Should I add a “decant calculator” next — like, “if I split this 100ml three ways, what’s each person paying per ml?”
•Anything else you’d want it to do?
Drop your numbers in the comments — what’s your daily spray count and which bottle are you currently reaching for? Curious to see the spread.
