How the comparison works
Cost per ml = total price ÷ fragrance volume. The 10 ml figure multiplies that unit cost by ten; it is a reference amount, not the price of a travel size offered for sale.
Worked example: the larger bottle is cheaper per ml
A hypothetical 50 ml bottle costing 100 gives 2 per ml. A 100 ml bottle costing 140 gives 1.4 per ml. The second has the lower unit cost, but buying it still requires 40 more upfront. These numbers are examples, not current product prices.
Compare the same edition and a realistic amount
Check the full name and concentration, not just the brand. EDT, EDP, Parfum and Intense may be different fragrances. A sample and a sealed retail bottle also have different purposes. Lower cost per ml does not measure scent quality, authenticity or longevity.
Gift sets, discounts and shared shipping
For a gift set, enter the volume of fragrance you are actually pricing. Do not add lotion volume to perfume volume. If the extras have value to you, consider that separately. Use the final discounted price; for a shared order, apply a consistent shipping allocation to both alternatives.
Use the result to decide what to buy
If you have never tried the exact edition, a small sample can be a sensible first step even at a higher unit cost. If you already use it regularly, compare larger sizes while considering your budget and likely use. This tool cannot tell you how many sprays a bottle will produce.
Read before buying
Does it convert currencies?
No. Convert your own amounts to one currency before entering them, using a source you trust.
Can I compare decants and full bottles?
Yes for unit cost. Packaging, seller reliability and your need to sample remain separate considerations.
Are the prices saved?
The tool calculates in your browser and does not send these input amounts to a server. Existing site analytics and ads still follow the site policies.
Why is zero volume rejected?
Division by zero has no meaningful cost-per-ml result. A zero price is permitted for a free sample.
