How Much Fragrance Oil Is Needed for 1,000 Candles?

The only sum on this page, and the three inputs it needs

Write it once: oil grams = number of candles × fill weight in grams × load. For the run this page uses throughout — 1,000 container candles, a 150 g fill, fragrance at 8% of wax weight — that is 1,000 × 150 × 0.08 = 12,000 g, twelve kilograms, 12 g in each candle. Nothing else here is more complicated than that sum with different numbers in it.

The part that trips people is the word "of". CSI's product pages state fragrance loads as a percentage of total wax weight — the Luxury Soy Wax CSI 464 page gives up to 10%, the Luxury Soy Wax Chunks page up to 13% of total wax weight with 8% as a starting point. Some makers instead work in percentage of the finished candle, which for the same candle is a smaller number: 12 g of oil in 162 g of poured candle is 7.4% of the candle but 8% of the wax. Neither convention is wrong, but they are not interchangeable, and at 1,000 candles the gap between them is roughly 0.9 kg of oil. Use the wax-weight convention, because that is the one the ceiling on your wax page is written in.

The second input is the fill weight, and it means wax, not vessel capacity. A jar sold as a 150 gram jar holds about 150 g of wax; the finished candle weighs more than that once the oil is in it. If your fill is actually 145 g because you leave a headspace, your thousand candles need 11.60 kg at 8%, not 12 kg. Weigh one poured candle's wax before you scale anything: a bench scale that reads to the gram — CSI lists a Candle Making Weighing Scale at ₹354.00 — settles an argument that a 5 g error would otherwise multiply by a thousand.

The third input is the load, and it is the only one of the three that is a judgement rather than a measurement. It is also the one that moves the bill most. The next section does nothing but show you that.

What the load does to 1,000 candles

The table below holds the run constant — 1,000 candles, 150 g of wax each, 150 kg of wax in total — and moves only the load. Oil is priced at the British Rose 1 kg rate of ₹3.07 per gram so that the comparison is clean; a dearer oil moves every row up together.

Read the first and last rows together. Between 6% and 10% the same thousand candles swallow 6 kg more oil and ₹18,408.00 more money, with no change to the wax, the wick, the jar or the label. That is the single largest controllable line in a fragrance budget, and it is decided by one cell in a spreadsheet.

Which way should you move it? Honestly, downward more often than makers expect. A reviewer of British Rose puts it better than a supplier can: Emma Bechara writes that "you can go for the minimum percentage in candle still it will give amazing smell". That is one maker's experience rather than a test result, but it points at a real mechanism — above a certain load, more oil stops adding throw and starts causing problems: sweating on a Chennai afternoon, wicks that drown, a cured surface that never looks right. The right way to settle it is a ladder test on twelve candles, not a guess across a thousand.

The ceiling is not a matter of taste. Two published numbers govern it, and the lower one wins: the wax grade's stated maximum and the oil page's stated candle range. CSI 464 states up to 10%; Luxury Soy Wax Chunks states up to 13% of total wax weight. On the oil side, British Rose states up to 10% of total wax weight for soy, Roasted Coffee states 6–10% for soy, and Mango Coconut states 6–10%. Pair Chunks with any of those three and your ceiling is 10%, not 13% — the wax would allow more, the oil page does not. Two oils on the CSI list do publish a range that reaches 13%: Japanese Cherry Blossom at 6–13% and Cinnamon Vanilla at up to 13% of total wax weight. Those are the only combinations where a 13% wax ceiling is usable, and even then a 13% run wants a thorough test burn before a thousand candles depend on it. These are the wax and oil manufacturers' stated formulation maximums, not limits anyone else sets.

Same 1,000 candles, five fill sizes

Because load is a percentage of wax, the fill size scales the oil in exact proportion. A brand that launches 1,000 votives and a brand that launches 1,000 large jars are running the same business with a 3.5× difference in fragrance spend. This table holds the load at 8% and moves only the fill.

One consequence worth pricing before you design a range. A brand that sells a 70 g votive alongside a 150 g jar is not carrying two scent inventories of equal size: at the same split, the votive line uses 5.6 g of oil per candle and the jar line 12 g. If you intend to run mixed sizes in one scent, work out the oil in grams per size and add them, rather than budgeting per candle. Mixed sizes are also where a scale earns its keep — a Silicon Measuring Beaker 250 ML at ₹600.00 and a Pen Thermometer at ₹354.00 are the two tools that stop a production day drifting.

The allowance: why 12 kg is not the number you order

Between the bottle and the jar, fragrance disappears in four places. There is film left inside the decanting beaker and the pouring pitcher. There is the overshoot on the scale — aiming for 12.0 g and getting 12.3 g, a thousand times. There is the batch you re-pour because the surface cratered. And there is the bottle you cannot fully empty, particularly the thicker resinous oils. None of it is dramatic; all of it is real.

This page carries 5% and says plainly that it is an assumption, not measured data. It is a starting figure for a maker who has never counted, and the right thing to do is replace it with your own number after one production run: weigh the oil you started with, weigh what is left, count the candles poured, and you have a measured wastage percentage that belongs to your bench rather than to a blog.

Notice how cheap the insurance is. Going from no allowance to 5% costs ₹1,840.80 across a thousand candles — less than the cost of the wax in four candles — and it is the difference between finishing the run and stopping 50 candles short of a festive order because the last bottle ran dry. Running short is never a 5% problem; it is a re-order, a second delivery and a fortnight you do not have in October.

Splitting 12.60 kg across a scent range

Very few brands sell a thousand candles in one fragrance. The moment you split the run, two things change: each scent needs its own pack combination, and each pack combination rounds up. Here is a five-scent festive range across the same 1,000 candles, weighted the way a real range is weighted — the bestseller carries 300 candles, the niche scent carries 100.

Three numbers are worth taking out of that table. The range needs 12,600 g and orders 12,800 g, so pack rounding alone adds ₹1,252.29 over buying the exact grams at the same per-gram rates — the price of not being able to buy 3,780 g of anything. The whole range costs ₹48,796.88, which is ₹48.80 of fragrance per candle. And the same thousand candles in British Rose alone would cost ₹38,751.20 — the five-scent range carries a ₹10,045.68 premium, most of it because four of the five oils cost more per gram than British Rose does.

That premium is not an argument against a range. A range sells; a single scent limits the size of the order you can accept, and a gifting client who wants three variants will not take one. It is an argument for choosing the number of scents deliberately, weighting them honestly, and knowing what the decision costs before the invoice arrives. If the answer is "we do not know which will sell", the cheaper experiment is three scents this season and five next, not five scents in quantities nobody can defend.

The pack ladder: what 12.60 kg costs depending on how you buy it

CSI lists most fragrance oils in a ladder of packs: a small trial bottle, then 50 gm, 100 gm, 500 gm and 1 kg. For British Rose that ladder runs ₹94.40 for 15 gm (₹6.29 per gram), ₹212.40 for 50 gm (₹4.25), ₹342.20 for 100 gm (₹3.42), ₹1,593.00 for 500 gm (₹3.19) and ₹3,068.00 for 1 kg (₹3.07). The per-gram rate falls as the pack grows, so the same 12.60 kg costs very different amounts depending on which rung you buy on.

That is ₹4,366.00 of pure packaging choice — the same oil, in the same candles, sold at three published rates. It is also why a maker who has grown to a thousand candles should stop reordering the pack size that suited fifty candles. The cost of the habit is roughly what the wax in another fifty-seven candles would cost at the CSI 464 5 kg rate.

Two honest qualifications, because the ladder does not behave the same way on every oil. First, on some oils the 500 gm and 1 kg rates are identical — Mango Coconut is ₹3.96 per gram at 500 gm and ₹3.96 at 1 kg, and Woody Oud is ₹4.53 at both. On those, buying the bigger pack saves you nothing per gram; buy the size that matches your requirement and skip the leftover. Second, the ladder stops at 1 kg. There is no larger listed pack and no published volume rate beyond it, so 13 kg of one oil is simply thirteen packs at the printed per-gram price.

Handling and storing 12.60 kg of oil in an Indian workshop

At this volume the oil stops being an ingredient and becomes inventory. Keep it sealed, out of sunlight, and as cool as the room allows — the same conditions CSI states for wax storage on the CSI 464 page, which gives a 60-month shelf life in cool, dry storage. The oil pages themselves do not publish a shelf life, so do not assume one; if it matters to your planning, ask on WhatsApp. What you can control is obvious and unglamorous: decant into a working bottle so the 1 kg pack is opened as rarely as possible, close caps between pours, and keep the stock away from the window in a Nagpur or Ahmedabad summer.

Flash point is a storage and handling number, not a throw ranking

Sixteen of CSI's 92 oil pages publish a numeric flash point; most do not. Where it is published, read it as a transport, storage and handling property — not as the temperature at which fragrance "burns off", and not as a measure of how strong an oil is. British Rose states 192°C and Eucalyptus Spearmint states 199°C, comfortably above the 80–90°C window at which CSI's soy pages say to add fragrance. A few sit lower: Palo Santo states 93°C and Gardenia Tuberose states 98°C. With those, add at the lower end of the window and stir rather than chasing temperature. Where a page publishes nothing, it is not published — ask on WhatsApp rather than assuming a figure.

Vanillin, discolouration and a thousand identical candles

Yellowing is cosmetic, but at a thousand units it is a consistency problem: a customer who buys two candles a month apart notices that one is cream and one is ivory. The oil pages publish what they know. British Rose states 0% vanillin and no discolouration in white wax; Eucalyptus Spearmint also states 0%. Cinnamon Vanilla states 2.5% vanillin with moderate discolouration, and Vanilla Bean states 2.5% with potential discolouration, recommending testing with lighter waxes. If a vanillin-carrying scent is in your range, plan for it: pour that scent last if you share equipment, or lean into it with a coloured wax, an amber jar or a tinted label rather than fighting it across a thousand candles.

Cure time is part of the oil plan, not an afterthought

Some oil pages give a 24–48 hour cure. Treat that as the earliest a candle can honestly be test-burned rather than the point at which throw is finished: the Luxury Soy Wax Chunks page itself says cure a minimum of 48 hours and ideally one to two weeks before burn testing, and 14–21 days is standard practice for soy container candles. For a thousand candles that is a calendar constraint, not a preference. Pour on 15 October and a 21-day cure lands on 5 November, three days before Diwali on 8 November 2026 — which is too late to ship. Pour by mid-October at the latest, and earlier if the candles have to travel.

One review is worth quoting here because it describes the practical side of a mixed order arriving: Renu writes "Ordered soy wax, fragrance oils, wax and thermometer — everything was great quality" and notes that packaging was secure. Consolidating a run's worth of oil, wax and wicks into a single order is generally the right instinct at this volume — fewer parcels, one set of delivery charges, one day of checking things in.

Worked example: a Jaipur brand ordering oil for 1,000 Diwali candles

What the example deliberately does not do is tell the Jaipur brand which five scents to sell. That is a market decision, and the sensible input is last season's orders rather than a supplier's opinion. What it does settle is the part that is pure arithmetic: how many grams, at what load, in which packs, by what date. Ordering timelines for Diwali and festive fragrance inventory planning cover the calendar side in more depth.

What this page cannot price for you

A 1,000-candle run has costs that no supplier catalogue can quote, and inventing numbers for them would make this page tidier and less useful. The rows below are blank on purpose, with a note on where your own figure comes from. Fill them in from bills you already have, then add them to the material total rather than pretending the material total is the whole picture.

Two of those deserve a sentence. Inbound delivery is a real cost that CSI does not publish a rate for, and two reviewers have said as much publicly about delivery charges — that is fair, and the practical answer at this volume is consolidation: one order carrying the oil, the wax, the wicks and the jars rather than four orders a fortnight apart. Ask for a delivery quote to your pincode on WhatsApp before you decide how to split it. And test candles are not overhead — they are the cheapest quality control in the business, but they are candles you will not sell, so count them honestly.

Everything on the CSI side of the ledger is on this page: ₹48,796.88 of fragrance oil for a five-scent range, or ₹38,751.20 for a single-scent run, both covering 1,000 candles of 150 g at 8% with a 5% wastage assumption. Prices include taxes, GST invoicing is available, and MSDS and IFRA documentation can be requested on WhatsApp. What the candles sell for, and whether that oil figure leaves room for everything else, is a pricing question rather than a quantity one.
