By Sonal Sahani · ISIPCA Versailles 11 min read Updated October 2026
You cannot, and this page is going to refuse the question rather than dress up a guess as an answer. Cost per application sounds like the most rational way to compare two fragrances, and it would be, if the numbers it needs existed. They do not. Three separate figures are required before the arithmetic means anything, and not one of the three is published - not by us, and not, as far as I have been able to find, by anybody selling attar. So instead of inventing them I am going to show you exactly which three are missing, why, and the one thing you can do in a fortnight that gives you a real number of your own.
Quick answers — read this first
Can you compare the cost per application of two attars? No, not from published information. The sum needs a measured volume delivered by each applicator, your own dabs per wearing and your own wears per period, and none of the three is published - not by SOSA and not, as far as I have found, by anybody in this category. There is no standard test for what one dab dispenses, so a figure published without a method would be a number rather than a measurement.

Why do applicators dispense different quantities? Because the delivery depends on the bottle and the hand together. How far you tip it, how long you hold it against skin, how warm the oil is, how full the bottle is, and whether the applicator is a dab wand, a roller or a stick all change the amount. That variability is real, and it is the main reason a per-application figure cannot be stated honestly.

What should I do instead? Measure your own. Write the date you opened the bottle on the box, then keep one line in your phone for fourteen days: the date, how many dabs, whether you topped up. At the end of it you know your own rate, and you can put it against published prices - a 3ml at ₹379 to ₹399, a 6ml at ₹669 to ₹699, a 12ml at ₹1,149 to ₹1,199. That number is yours and nobody else needs to supply it.
The short answer
Short answer: You cannot compare it, because the comparison needs a measured volume per dab, a matched dabs-per-wear habit and a matched wear count, and none of the three is published anywhere in this category including by us. Measure your own instead.
The pick: Nothing on this page, and that is deliberate. The pick is a pen: write the date you opened the bottle on the box, count your own dabs for a fortnight, and you will have a rate that is true for your hand - which is the only place such a number was ever going to be true.
Honest note: an attar is bought unsmelled, so a list of notes is all you have. A note list describes an intention, not a smell, and nothing written here is a substitute for wearing it.
Four attars - lightest opening to deepest baseAdaa · Mastani · Ameeri · Nawaab3ml from ₹379  |  6ml from ₹669  |  12ml from ₹1,149Dab on pulse points - oil wants warmth, not rubbing6-8 hours on skin · alcohol-free · DPG-free carrier
There are four SOSA attars and they run from a bergamot-and-cardamom opening at the lightest end to white royal oud at the deepest. Adaa is the freshest, Mastani the most floral, Ameeri the warmest, Nawaab the deepest. All four are alcohol-free on a jojoba carrier with no DPG, come with a dab applicator, and wear 6-8 hours on skin - longer on warm or oily skin. Sizes are 3ml, 6ml and 12ml, from Rs 379. None of that tells you whether you will like the smell, which is why the smallest size exists.
Straight answer
Why can nobody tell me the cost per application of an attar?
Because the arithmetic needs three inputs and the category publishes none of them.

The figure you would need first: a measured volume per application. How much oil does one dab of that particular bottle actually deliver, measured on a stated method? Nobody publishes this, and it is worth understanding why rather than assuming bad faith. The amount an applicator delivers changes with how far you tip the bottle, how long you hold it against the skin, how warm the oil is that day, how full the bottle is, and what the applicator is - a dab wand, a roller and a stick all behave differently, which is exactly the difference you have noticed. There is no agreed test for it. A figure published without a method attached would be a number, not a measurement.

The second: a matched application habit. Yours. How many dabs you put on in one wearing, and where. One dab at a pulse point and three dabs across neck and wrists differ by a factor of three, and that factor swamps every other variable in the sum. No brand knows this about you, and borrowing somebody else's habit to compare two bottles tells you about their hand rather than yours.

The third: a matched wear count. How often you actually wear it, and whether you top up during the day. An attar kept for occasions and an attar worn before work every morning produce completely different answers from the same bottle, and the second one is the reason the phrase "cost per application" feels meaningful in the first place.

What is published, and what is not. We publish the composition of each of the four in the order you meet it, the carrier - jojoba, no DPG, no alcohol - the format, the three sizes, the price of each, and one wear figure: 6-8 hours on skin, longer on warm or oily skin. We do not publish a drop count, a dabs-per-bottle figure or a cost per application, because we have not measured them under any method I would be willing to defend. And I know of no published method for it anywhere in this category - no standard dab, no standard definition of an application, no standard test. I am not going to characterise what any other company does or does not publish; what I can tell you is that I have looked for such a method and not found one.

So what is a cost-per-wear number on a page, when you see one? An assembly of assumptions. An assumed drops per millilitre, an assumed dabs per wear, and usually an assumed number of wears per bottle. Change any one of the three and the number changes, often by a lot. It is not dishonest to do that arithmetic for yourself with your own inputs - it is useful. It is dishonest to publish the output as though it were a specification, and when you see one it is worth asking which three assumptions went into it. The same missing method is what makes a big longevity claim in a review unreadable.

Now the part you can actually do, and it takes a fortnight. One: date the bottle. Write the day you opened it on the box, or on the base of the bottle if there is room. This single habit is worth more than every per-application estimate on the internet put together. Two: count your dabs. For fourteen days, keep one line in your phone - the date, how many dabs, whether you topped up. Three: look at what you have. You now know your own dabs per week, from your own hand, on your own skin, with your own habits. Four: do the sum with real prices. Ours are published and stable: a 3ml is ₹379 to ₹399, a 6ml is ₹669 to ₹699, a 12ml is ₹1,149 to ₹1,199, and the same liquid fills all three. Your own dab count against those prices gives you a figure that is genuinely yours, and you will never need anybody else's.

And in the meantime, compare on what is comparable. Price at a stated size. The composition, published in order. The carrier. Whether one wear figure is stated plainly or several contradictory ones are implied. Whether a size exists that is small enough to test. Those are all checkable before you pay, and between two bottles they tell you far more than an invented cost per wear ever would. The full checklist for a product page is here, and what we publish about the contents - and what to ask us instead - is here.
The comparison needs three figures - volume per dab, your dabs per wear, your wears per week - and none of them is published, ours included. Anybody showing you a cost per wear has assembled it from assumptions. Date the bottle, count your dabs for a fortnight, and the number becomes yours.
There is nothing to buy on this page yet, and that is the honest answer. There are four SOSA attars and none of them is the thing you have described. Four compositions is the whole range, so where your answer is a standalone musk, a pure sandalwood, an amber, a tuberose, a vetiver or an aquatic, we do not make it and would rather say so than sell you the nearest thing. Tell us what you wear now and we will say whether any of the four fits.
Tell us what you wear

The three figures the comparison needs

Each of these has to be known for both bottles and matched to you before a cost per application means anything. Two of the three only you can supply.

1
Volume per dab
Not published, and not measurable without a stated method
The amount an applicator delivers moves with the tilt of the bottle, the contact time, the temperature of the oil, how full the bottle is and the type of applicator. A dab wand, a roller and a stick behave differently from each other, which is the difference you have already noticed between two bottles. Without an agreed test, any drops-per-millilitre figure is an assumption wearing the clothes of a specification.
Tip: If a page gives you a drop count, ask what method produced it.
2
Your dabs per wear
Only you have this, and it swings the answer more than anything else
One dab at a pulse point against three across neck and wrists is a factor of three, and it dwarfs every other variable in the sum. No brand can know it, and borrowing an average from somewhere tells you about that person rather than about either bottle. One dab is the dose I would start from, two if you want it read across a dinner table, and never rubbed in - oil opens with warmth and rubbing crushes the top of the composition.
Tip: Count your own for fourteen days before you try to compare anything.
3
Your wears per period
An occasion fragrance and a daily one give different answers from the same bottle
The same composition, the same applicator and the same hand produce completely different per-application economics depending on whether you wear it twice a month or every morning. That is not a property of the fragrance. It is a property of your life, and it is the reason two people can honestly reach opposite conclusions about the same two bottles.
Tip: Decide how often you will wear it before you decide which size to buy.
The SOSA principle
A number with no method behind it is not a measurement. It is a decision somebody made about three assumptions, printed in a font that makes it look like a fact.
Ask what went into it before you compare two bottles with it.

What is published, and what is not

Published for all four: the composition in the order you meet it, the carrier, the format, the three sizes, each price, and 6-8 hours on skin, longer on warm or oily skin. The sizes are a 3ml at ₹379 to ₹399, a 6ml at ₹669 to ₹699 and a 12ml at ₹1,149 to ₹1,199, and the same blend fills all three. Those figures are stable and you can do arithmetic with them.

The SOSA attar range
The four numbers, and which of them you can actually get
Option When it is the right call
A measured volume per dab Would make the sum possible · needs an agreed test method
Status: Not published - not by us, and no standard method exists that I have been able to find
Your own dabs per wearing The single biggest variable · one dab against three is a factor of three
Status: Only you can supply it, and fourteen days of notes is enough
Your own wears per week Turns a rate into a cost · occasion wear and daily wear are not comparable
Status: Only you can supply it, and you probably already know it roughly
A cost-per-wear figure on a page Looks like a specification
Status: An assembly of three assumptions - change any one and the number moves, so ask which three before you compare anything with it

Not published, and not estimated either: drops per millilitre, dabs per bottle, cost per application, and any figure for how long a bottle will serve you. Those would all require a measurement method we do not have, and a model of your habits we have no business assuming. I would rather have a shorter specification sheet than a longer one with guesses on it.

Not sure which of the four is yours?
Tell us the three fragrances you wear most and the notes you cannot stand. If none of our four fits what you describe, we will say so rather than sell you a bottle you will not wear.
Ask first
Two of the three figures this sum needs are about your hand, not about the bottle. That is why only you can ever finish the arithmetic.

The SOSA attar range

Every SOSA attar is alcohol-free and IFRA-compliant on a jojoba carrier with no DPG, hand-blended in small batches in Pune. A portion of every order supports girl-child education through Nanhi Kali. There are four, and the honest way to read them is by depth - how much the base note is doing.

The SOSA attar range
Four attars, lightest to deepest - 3ml from ₹379
Attar Built on What it is, honestly 3ml
Adaa Bergamot, green cardamom, jasmine sambac, white musk The lightest of the four and the easiest first attar. Jasmine sambac is mogra, so this is also the mogra answer ₹379
Ameeri Taif rose, Indian sandalwood, Persian saffron, soft oudh The warm one. Rose and sandalwood doing most of the work, with the oudh kept soft ₹385
Mastani Night-blooming jasmine, Damask rose, oudh The most floral. A different jasmine and a different rose from Adaa and Ameeri ₹389
Nawaab White royal oud, sandalwood, saffron, tobacco leaf, amber, leather The deepest in the range. Not a first attar unless you already know you like oud ₹399
The trio Ameeri, Nawaab and Mastani together Three of the four at once. The honest answer when you cannot choose and will not guess ₹1,055

Four honest notes. A note list is not a smell. Every composition above is described in the words we would use ourselves, and those words still cannot tell you how it will sit on your skin - which is the whole reason the 3ml exists. On the sizes: 3ml, 6ml and 12ml are the same liquid, and the only reason to buy the larger ones is that you already know. If you have not worn it, buy the smallest and let it earn the upgrade. On wear: all four are 6-8 hours on skin, longer on warm or oily skin, and that is the only figure we publish. We do not publish a drop count, a per-application cost, or a comparison with how long anybody else's fragrance lasts - including sprays. On what we do not make: there is no standalone musk, sandalwood, amber, tuberose, vetiver, khus, aquatic or tobacco attar in this range. Four compositions is the whole range, and where your answer is not one of them, this page will say so rather than talk you into the nearest thing.

A note from Sonal

Attars are the part of this business where the marketing is worst, and I would like ours to be the boring, accurate version. Most of the category sells a bottle on adjectives - royal, exotic, hypnotic, long-lasting - and on numbers nobody has measured. You cannot smell any of it before you pay, so the words are doing all the work, and almost nobody writes them honestly.

So here is what I will and will not tell you. I will tell you what is in each of the four, in the order you meet it, and that they wear 6-8 hours on my skin. I will not tell you that one of them smells expensive, or that it will turn heads, or that it lasts twelve hours, because I cannot know the first two about you and have not measured the third. The honest sequence is: read the notes, buy the 3ml, wear it for a week, and only then buy a size. If none of our four matches what you have described to yourself, I would rather say so than sell you the nearest one.

The other thing worth knowing is how little you need. An attar is concentrated oil, and the commonest mistake is wearing it like a spray - a long press at the neck and another at the wrists. One dab at a pulse point is the dose. Two if you want it read across a dinner table. Do not rub it in; oil opens with warmth, and rubbing crushes the top of it. That is the entire dial, and most people never need the top of it. A portion of every order supports girl-child education.

Frequently asked questions

What is the cost per application of a SOSA attar?
We do not publish one, and I am not going to estimate it. It would require a measured volume per dab, which has no agreed test method, plus your own dabs per wearing and your own wears per period, which only you know. What we do publish is the price of each size - Rs 379 to Rs 399 at 3ml, Rs 669 to Rs 699 at 6ml, Rs 1,149 to Rs 1,199 at 12ml - and 6 to 8 hours on skin.
How many drops are in a 3ml attar bottle?
I do not know, and nor does anybody who has not measured it under a stated method. A drop is not a fixed unit from a dab applicator, and the amount delivered changes with tilt, contact time, oil temperature and how full the bottle is. We publish no drop count for any of the four sizes.
Someone showed me a cost-per-wear calculation. Is it wrong?
Not necessarily wrong - just assembled. It will contain an assumed drops-per-millilitre, an assumed dabs-per-wear and usually an assumed number of wears. Ask what those three assumptions were. If they are not stated, the number is not comparable with any other number, including one built the same way by somebody else.
How can I work out my own cost per application?
Write the date you opened the bottle on the box. For fourteen days, note the date, how many dabs you applied and whether you topped up. That gives you your own rate, and you can put it against the published price of the size you bought. The figure is then true for your hand, which is the only place it was ever going to be true.
What should I compare between two attars instead?
Price at a stated size, the composition published in the order you meet it, the carrier the oil sits in, the concentration format, whether one wear figure is stated plainly rather than several contradictory ones implied, and whether a size exists small enough to test. All of those are checkable before you pay.

About this guide:
  • Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product recommendations reflect the SOSA range; the fragrance-family guidance applies to any brand. SOSA does not sort fragrance by the gender of the wearer.


What this guide does not claim.
  • An attar is a fragrance and nothing else.
A note list is not a smell
  • - it names what a composition is built from and the order you meet it in, which is a description of an intention rather than a measurement, and it is
not a substitute for wearing it
  • . Nothing here should be read as advice about health, allergies or anyone's wellbeing, and no fragrance on this page is claimed to affect anybody's mood, comfort, confidence or state of mind. Where a reader describes a preference none of our four compositions matches, these guides say so and sell nothing.


SOSA attars, specified:
  • four compositions -
Adaa
  • (bergamot, green cardamom, jasmine sambac, white musk),
Ameeri
  • (Taif rose, Indian sandalwood, Persian saffron, soft oudh),
Mastani
  • (night-blooming jasmine, Damask rose, oudh) and
Nawaab
  • (white royal oud, sandalwood, saffron, black pepper, cardamom, aged tobacco leaf, amber, leather, white musk). All four are
alcohol-free and IFRA-compliant on a jojoba carrier with no DPG
  • , supplied with a built-in dab applicator, and hand-blended in small batches in Pune. Sizes are
3ml, 6ml and 12ml
  • : Adaa ₹379 / ₹669 / ₹1,149, Ameeri ₹385 / ₹679 / ₹1,165, Mastani ₹389 / ₹685 / ₹1,179, Nawaab ₹399 / ₹699 / ₹1,199. The three-attar trio (Ameeri, Nawaab, Mastani) is ₹1,055 / ₹1,859 / ₹3,189. The same liquid fills all three sizes.


On wear.
  • SOSA publishes one figure:
6-8 hours on skin, longer on warm or oily skin
  • . SOSA does not publish a drop count, a cost per application, a projection rating, or any comparison with how long another format or another company's fragrance lasts. Where a customer review reports a different number, that is one person's experience of their own skin and not a measurement SOSA stands behind.


On what is in the bottle.
  • The composition lists above name the materials a fragrance is built from. They are not a statement of grade, percentage or geographic origin, and this guide makes no claim about either. Where origin or grade matters to you, ask before you buy - that is a fair question and the answer belongs to the product page rather than to an article.


On other companies.
  • Where another fragrance brand is named in these guides it is because a reader named it, and the page answers what they asked. Nothing here states what any other company's product contains, how long it lasts, what it costs or how it performs.
Other brands named are the property of their respective owners · SOSA is not affiliated with, endorsed by, sponsored by or associated with any other fragrance company named on this page
  • , and no other company has reviewed or approved this content. If a product you already own suits you, keep it - several pages in this guide say exactly that.


On availability.
  • SOSA is an online fragrance house and ships across India; it holds no retail counters, and no delivery window is quoted here. A portion of every order supports girl-child education through Nanhi Kali. Prices and availability change - see the live product pages.
