I Have ₹2 Lakh Worth of Fragrance Oils but Some Scents Barely Sell — How Do I Measure the Cost of Money Trapped in Slow-Moving Raw Materials?

Three different costs, and only one of them is arithmetic

Money sitting in fragrance oil costs you in three separate ways, and the reason most makers never put a number on any of them is that they try to solve all three at once. Separate them and one of the three turns out to be pure arithmetic you can do tonight.

The cost of the money itself. Every rupee in a bottle on your shelf is a rupee that cannot pay a courier bill, buy a 10 kg sack of wax or fund a Diwali production run. Whether that costs you interest on an overdraft, a missed purchase, or simply sleep, it costs something. This is the one that is arithmetic, and the rest of this page is about measuring it.

The cost of the space and the conditions. A shelf in Nagpur or Ahmedabad in May is a different storage environment from one in Pune, and oils held through a Mumbai monsoon are held in humidity. No CSI fragrance oil page publishes a shelf life, so this page states none and you should not assume one — ask on WhatsApp for documentation on a specific oil. What can be said is that keeping bottles closed, cool and out of direct sunlight is ordinary practice, and that the cost of failing to is not a percentage anyone can hand you.

The cost of being wrong about the scent. If a scent will never sell, the money is not trapped, it is gone, and no amount of patience recovers it. This is the cost that feels largest and is hardest to size, because it depends on a judgement about demand that only you can make. The rupee-month figure below deliberately does not try to price it. It prices the waiting, and it lets you see which lines are waiting long enough that the judgement matters.

The unit that needs no interest rate

Here is the whole method. For each scent, take what it is worth on your shelf today and multiply it by how many months it will take you to use it at your current rate of selling. A bottle worth ₹10,000.00 that clears in two months is 20,000 rupee-months. A bottle worth ₹5,000.00 that clears in twenty months is 100,000 rupee-months — a quarter of the money doing five times the waiting.

Rupee-months is not an accounting standard and you will not find it in a textbook under that name; it is simply the product of the two things that matter, kept in a unit that cannot be faked. Its virtue is that it needs no rate. The cost of capital multiplies every line of your shelf by the same number, so it changes how big the answer looks and never changes which scent is the problem. That means you can do the ranking tonight and have the argument about interest rates later, or never.

One honest refinement. Value multiplied by months of cover measures the full amount held against the time the last gram waits. If your stock runs down evenly, the average balance tied up over that period is about half the opening value, so the average capital tied is roughly half the figure. Use whichever definition you prefer and stay with it — the ranking is identical either way, because halving every line halves the total too.

Your ₹2 lakh, scent by scent

The shelf below is built from real CSI 1 kg packs and comes to ₹2,02,047.80 — close enough to the ₹2,00,000 in your question to read the shape off, and every rate is printed on a product page you can open. The kilograms held and the monthly candle sales per scent are illustrative; they are chosen to look like a real eight-scent range rather than to prove a point, with three scents carrying the business, two in the middle and three that barely move.

Consumption is arithmetic, not opinion: the recipe is 150 g of wax at an 8% fragrance load, so 12 g of oil a candle and 162 g poured. That fill reading — load as a percentage of wax weight — is carried through every figure on this page. At 663 candles a month across the range the whole shelf draws 7.96 kg of oil a month, which is ₹37,681.99 of fragrance at these rates.

Read the two right-hand columns together. Roasted Coffee is the biggest single value on the shelf at ₹22,428.00 and it is the second smallest problem, because 180 candles a month clear it in 2.8 months. Tangerine is worth ₹47,996.00 — less than a quarter of the shelf — and carries 19,99,833 rupee-months, which is 66.4% of the total. Four kilograms of an oil that sells 8 candles a month is, on this recipe, 41.7 months of cover: three and a half years.

What the ranking changes

Group the eight scents into three bands and the shape of the problem becomes a single sentence. The movers and the middle together are just under half the shelf by value and about a tenth of it by cash-time. The three slow scents are the other half of the money and almost all of the waiting.

That is the sentence worth writing on the whiteboard: 52.4% of the money is 89.9% of the waiting. It also explains a feeling most growing candle brands in India will recognise — that the fragrance shelf keeps getting bigger while the scents customers actually ask for keep running out. The fast scents turn over so quickly that they barely register as stock; the slow ones never leave, so the shelf is mostly made of them.

One caveat before you act on the ranking. A scent can be slow and still be worth holding: a wedding or corporate gifting scent that sells eighty candles in one November order will show terrible cover for eleven months of the year and be entirely correct to hold. Cover measures the average; your calendar knows the lumps. Mark those lines before you cut them, and judge them against a year rather than a month.

Buying the pack the demand justifies

Slow stock has an origin, and it is usually a kilogram bought for a scent that had never sold a hundred candles. So the most useful thing this page can tell you is what the smaller pack actually costs, oil by oil, because the answer is not the same across the range and it is not a rule you can carry between products.

Read it and the advice writes itself, per oil rather than in general. On Peach Melon Berry and Woody Oud the 100 g pack is the same rate per gram as the kilogram, so a trial costs nothing at all in rate terms and there is no argument for committing early. On Tangerine the 100 g pack is fractionally cheaper per gram than the kilogram, and the cheapest rate on the whole ladder is the 50 g pack at ₹11.98/g — so the kilogram of Tangerine that created most of the cash-time on this shelf did not even buy a better rate.

Citronella is the exception that makes the point. Its 100 g pack is ₹767.00 at ₹7.67 a gram against ₹2.89 a gram in the kilogram — ₹4.78 a gram more to trial it. For an oil like that, being wrong in small quantities is genuinely expensive, and the sensible move is to be more certain before you buy at all rather than to buy small. Check the ladder on the product page before you decide which way to be careful.

What the pages publish about keeping it, and what they do not

For the fragrance oils on this page the position is simple: no CSI fragrance oil page publishes a shelf life. Not one of the eight. This page therefore states none, offers no estimate, and suggests you ask on WhatsApp for the documentation on any oil you are holding in quantity. Treating an unpublished figure as though it existed is how a maker talks themselves into either panic or complacency, and both cost money.

Two wax pages do publish one, which is worth knowing for contrast. Luxury Soy Wax CSI 464 states a shelf life of 60 months in cool, dry storage and asks that it be kept away from sunlight and moisture. So if you are holding both, your wax has a published storage window and your oils do not — which is the reverse of what most people assume, because the oils are the expensive line.

What the oil pages do publish is often more immediately useful than a date. Vanilla Bean states 2.5% vanillin content and notes potential discolouration, suggesting a test in lighter wax — that is a cosmetic effect, not a safety one, and it is a real consideration for stock that will be poured into white soy a year from now. Roasted Coffee states a flashpoint of approximately 191–193°C, which is a transport, storage and handling property rather than a ranking of throw, and sits well above the 80–90°C at which fragrance is added.

Where an oil page publishes no candle usage range at all — on this shelf that is Tangerine, Santal Noir and Spicy Cinnamon — then the wax grade's stated maximum is the only published limit you have. On Luxury Soy Wax CSI 464 that is 10% of total wax weight. Say that to yourself rather than inventing a range, and ask CSI on WhatsApp if you need the oil's own documentation.

Three exits, and what each actually recovers

Take the 4 kg of Tangerine, worth ₹47,996.00 at the live rate, selling 8 candles a month and carrying 41.7 months of cover. There are three things you can do with it and one thing you cannot: you cannot get the purchase price back. That money left when the order was paid for. Everything below is about what happens from here.

Blending down. Fold it into a scent that sells. At a quarter of the blend by weight with Roasted Coffee, the blended oil costs ₹5,803.25 a kilogram, which on 12 g a candle is ₹69.64 against ₹44.86 for Roasted Coffee alone — ₹24.78 more per candle, or ₹4,460.94 a month across the 180 candles of that line. In exchange, the Roasted Coffee line now draws 0.54 kg of Tangerine a month, so cover falls from 41.7 months to 7.4 months and ₹14,952.00 of Roasted Coffee is never bought.

That last figure is the honest one, and it is smaller than people expect. Blending recovers the cost of the oil it replaces, not the cost of the oil it uses. Four kilograms of Tangerine displaces four kilograms of Roasted Coffee purchases, which is ₹14,952.00. The remaining ₹33,044.00 — the gap between what you paid for the Tangerine and what the oil it replaces would have cost — does not come back in any scenario. Knowing that number is the point of doing the arithmetic.

Two things blending is not. It is not free: your bestselling scent changes, and a customer who buys Roasted Coffee because of how it smells is being handed something else. Test it, cure it and burn it before it goes near a customer, and treat it as a new product rather than a cost-saving. It is also not unlimited: where an oil page publishes no candle usage range, as Tangerine's does not, the wax grade's stated maximum of 10% of total wax weight is your only published limit, and the blend still has to sit under it. At 8% of wax weight this one does.

Notice what the third row does and does not do. Raising the load from 8% to the wax grade's stated maximum of 10% takes the draw from 96 g a month to 120 g and cover from 41.7 months to 33.3 months. It moves the number and does not solve the problem, because the problem is that eight people a month want that candle. Load is a formulation decision that belongs to throw and safety, not a stock-clearing lever, and using it as one will produce a candle you did not test for a reason you will not remember in six months.

Finishing the sum with your own cost of capital

Rupee-months gets you the ranking and the relative sizes. To turn it into rupees you need one more number, and it is the one number on this page that cannot come from CSI: what a month of your own money costs. That might be an overdraft rate, the terms your own suppliers give you, or simply what the cash would have done inside your business if it were not in a bottle. It is not a figure CSI publishes, it is not a figure this page will guess at, and it is not tax or financial advice — if the number matters to a decision you are about to make, it is worth a conversation with your own adviser.

If you want a single number to carry into a decision, use the rupee-months of the slow band divided by twelve — that is the average rupees of your money tied up in slow stock for a whole year, in a unit everyone understands. On the worked shelf that is roughly ₹2,25,891.67 of annual capital sitting in three scents, against ₹14,221.94 across the three that pay the bills.

One last note on what this exercise is for. It is not an argument for holding no stock — a candle business that runs out of its bestselling scent in the week before Diwali has made a far more expensive mistake than one holding four kilograms of a slow oil. The point is that the two risks should be sized in the same unit, and rupee-months is a unit that can hold both.
