Tool
Per-mL Cost Calculator
Price a fragrance decant or partial bottle by its effective cost per milliliter. Compare fairly across different sizes and fill levels.
Enter price, bottle size, and fill level above
How to use this: Enter the asking price, the full bottle size in mL, and the current fill percentage. The calculator shows the effective cost per milliliter so you can compare decants, partial bottles, and different sizes on equal footing.
Compare against the Scentledger median for the full bottle to see whether a partial-bottle price is fair. See also: Buying & Selling Fragrance Fairly for full seller and buyer checklists.
