I Need 5,000 × 80 g Diwali Candles at 8% Fragrance — How Many Kilograms of Wax and Fragrance Oil Should I Book with My Supplier?

The 400 kg split, done properly

Every quantity on this page comes from one rule that CSI uses across the whole calculator series: fragrance load is a share of the finished candle weight. The client asked for an 80 g candle, so 80 g is the finished weight. At 8%, the oil is 80 × 0.08 = 6.4 g and the wax is the remainder, 80 − 6.4 = 73.6 g. Nothing else in the booking is worked out until those two numbers are fixed, because every later step multiplies them.

The check row matters more than it looks. When the order runs to hundreds of kilos, a single slipped decimal disappears into the total. Oil plus wax must equal the finished weight, every time. If your sheet shows 368 kg of wax and 32 kg of oil, it adds to 400 kg, and 400 kg ÷ 5,000 is 80 g. Every number cross-checks the others. The same method, at smaller volumes, is laid out in the 2,000 × 150 g calculation, and the same 80 g format at double this volume is in the 10,000 × 80 g wedding calculation.

The load can be different from 8%, and the split moves with it. The wax maker rates Luxury Soy Wax Chunks up to 13% fragrance load, and Luxury Soy Wax CSI 464 up to 10%. Those are formulation maximums, not targets and not regulatory limits. Here is how the booking changes at 6% and 10%, with the same 25 test candles and 3% pour loss built in:

A two-point change in load moves the oil booking by about 8.3 kg and the wax booking by the same amount the other way. In rupees, the oil move matters far more: 8.3 kg of Sandalwood at ₹5.03 a gram is roughly ₹41,627.94, against about ₹4,960.44 of wax. Fix the load with a burn test before you book. Do not raise it later to rescue a weak candle; development and QC samples covers how to budget that test oil.

What goes on top of the net figure

The net figure assumes every gram you melt ends up inside a sold tin. That never happens. Two allowances belong on a Diwali booking of this size, and they go on in a set order: fixed extra candles first, percentage loss second, pack rounding last. Doing it in that order means the percentage covers the test candles too, and the rounding covers everything.

Tins and wicks follow the same order, but their allowances are different in kind. A tin does not evaporate or stick to a jug; it dents, or arrives with a scratch that fails your quality check. A wick can be set crooked and pulled. We have used a 1% allowance for tins and 2% for wicks, both labelled assumptions. On 5,025 candles that is 5,076 tins and 5,126 wicks before pack rounding. Wick size for an 80 g tin is not published in our data; the Eco Thin C1 is priced here as an example, and your burn test decides whether it is the right wick.

Rounding to packs and pricing the booking

The Golden Aluminium Tin is one of only two containers in CSI's data with a published fill: 85 g. An 80 g finished candle sits under that with a little headroom, which is why it is the example here. If your client wants glass, the fill weight of most CSI jars is not published, so weigh a test fill before you book; My Jar Holds 180 g of Water — How Do I Estimate the Wax Fill Weight Before Buying Wax for 500 Jars? shows how to go from a water fill to a wax fill. Per candle, the material cost comes out at ₹44.09 of wax, ₹32.17 of Sandalwood, ₹30.00 for the tin and ₹5.90 for the wick: ₹112.16. That excludes labour, labels, boxes, freight and GST, which you price yourself.

The same honesty applies to oil. For most oils in the catalogue, the 1 kg costs about the same per gram as the 100 g and the 500 g; per-gram price breaks above 100 g are rare. Sandalwood is priced at ₹5.03 a gram at 100 g, 500 g and 1 kg alike, so buying it in kilos buys you fewer bottles to open, not a lower rate. Some oils do break, and one runs the other way at 500 g, which the next section uses to change the booking.

Choosing the oil for a 33 kg booking

At 33.1 kg of one oil, the fragrance line is where the money moves. A single oil needed in that quantity also has to be in stock in that quantity, which is a reason to confirm availability on WhatsApp before you promise a scent. Here is the same gross oil need priced across four oils that suit a Diwali tin, each rounded to its own packs:

The last row is the one to read twice. Saffron Cedarwood's 1 kg is listed at ₹6,867.60 (₹6.87 a gram), but its 500 g is ₹2,584.20 (₹5.17 a gram). Booking it as 34 × 1 kg would cost ₹2,33,498.40. Booking it as 67 × 500 g costs ₹1,73,141.40, a difference of ₹60,357.00 for exactly the same oil. For a 33 kg booking, the pack you pick can matter more than the oil you pick. Jasmine is the other useful case: its 1 kg is ₹3.92 a gram against ₹4.30 at 100 g, one of the oils where the kilo genuinely saves money.

We have not published throw measurements for any oil, so none of these is ranked by strength. The choice between them is your client's scent brief, your price point and a burn test in your wax and tin. Buy a 15 g of each shortlisted oil first; 15 g scents two 80 g test candles at 6.4 g each with 2.2 g to spare. If the client wants two or three scents rather than one, the order becomes a split, and My Client Wants 60% Lavender and 40% Vanilla Candles Across a 2,000-Piece Order — How Do I Calculate Separate Fragrance Quantities? shows how to divide the oil without changing the wax.

The booking calendar to 8 November

Today is Tuesday 29 September 2026 and Diwali is Sunday 8 November, 40 days away. A corporate or retail client usually wants festive stock in hand a week or more before the day. Work backwards. The dates below are an example plan, not CSI delivery times, which are not published; confirm dispatch for a booking of this size on WhatsApp before you commit dates to a client.

Two things follow from the calendar. First, the test candles need material this week, even if the bulk booking is still being quoted. That is 1.84 kg of wax and 160 g of oil for 25 candles, which a 5 kg bag and a 15 g or 50 g tester of the chosen oil cover easily. Second, the full booking must be on your bench before the first production day. If a split delivery would suit your storage, ask for it; whether CSI can hold part of a booking for later dispatch is a WhatsApp conversation, not a published policy.

If the client says the quantity might grow, do not add it to this booking by default. The cost of buying for an order that has not been confirmed is different for wax, which you can use on any later job, and for a single named fragrance, which you may not. My Client May Increase a 1,000-Candle Order by 20% at the Last Minute — Should I Buy Additional Raw Materials Now or Wait for Confirmation? prices both sides of that decision. If Diwali is one of three jobs landing in the same month, pool the wax across them and keep the oils apart, as I Have Three Bulk Orders Happening in the Same Month — How Do I Combine Their Wax Requirements While Keeping Fragrance Oils and Packaging Quantities Separate? shows.

Once the run is done, write down what you actually used. If your pour loss came in at 2% rather than 3%, your next festive booking can be 3.7 kg of wax lighter for the same order. If it came in at 5%, you were short, and you now know by how much. That record is worth more than any rule of thumb.
