My Candle Uses a 50:30:20 Coffee-Vanilla-Sandalwood Blend — How Much of Each Fragrance Oil Should I Order for 500 Candles?

The missing number: candle size

Every quantity on this page flows from one number the question does not give: the finished weight of each candle. We assume 200 g, the default container size in this series, at 8% total fragrance measured on the finished candle. That gives 16 g of blend and 184 g of wax per candle. If your candle is a different weight, the method is the same and every figure scales in direct proportion; there is a table for that below. If you only know your jar's volume, not its fill weight, weigh a test pour first. Estimating fill weight from a water fill shows the method.

The component sheet

Build the order in the same sequence every time: total fragrance per candle, then per run, then allowances on the total, then split by the ratio. Five QC candles are a fixed quantity (one for retained sample, the rest for burn and cure checks during the run), so they are added to the count before the percentage allowance.

Three things to notice. The allowance is applied once, to the total, and then shared by the ratio, so the components stay in proportion. The QC candles are real candles, and they need wax, wicks and jars as well as oil. And the per-candle grams are small for the minor components: 3.2 g of sandalwood in a 200 g candle. Weighed one candle at a time on a whole-gram scale, that component can drift by 15% either way, which is why a premixed blend is the norm for runs of this size. The smallest-component page works through that precision problem at 100 kg.

If your candle is not 200 g

Because every quantity is candle weight × load × share, a different candle weight scales every line by the same factor. Here is the same order (505 candles poured including QC, 8% total, 3% allowance) at four common weights:

A 50 g difference in candle weight moves the coffee line by over a kilo. That is why the fill weight has to be weighed, not read off a jar's millilitre rating. If your load is not 8%, the scaling works the same way: at 6% multiply the 8% figures by 0.75, at 10% by 1.25. Check any load against your wax's stated ceiling (Luxury Soy Wax Chunks up to 13%, CSI 464 up to 10%).

Rounding three oils to packs

For a 500-candle run we round each component using CSI's 100 g, 500 g and 1 kg sizes only, and leave the 15 g and 50 g for testing. Each oil is rounded on its own:

The vanilla line is the tightest: 2,500 g against a need of 2,496.7 g, only 3.28 g spare after the allowance. If your real pour loss runs above 3%, add a 100 g of Dark Vanilla (₹790.00) to the order. Sandalwood is priced flat at ₹5.03 a gram from 100 g to 1 kg, so it makes no difference whether you buy 1 kg + 500 g + 2 × 100 g or seventeen 100 g bottles. Roasted Coffee's kilo is about 4% cheaper per gram than its 100 g, and Dark Vanilla's about 3%; none of the three is among the 24 oils with a kilo saving of 5% or more. For more than the listed packs of any of them, CSI quotes on WhatsApp and publishes no discount figure. When kilo buying becomes economical explains that pattern.

The wax, wicks and jars

The wax is the largest quantity in the order: 505 × 184 g × 1.03 = 95,707.6 g, about 96 kilos. Luxury Soy Wax Chunks are listed up to 10 kg bags, so at listed prices that is 9 × 10 kg + 1 × 5 kg + 1 × 1 kg, ₹57,585.00. Natural Soy Pearl Wax, the one CSI wax with a real bulk break and a 50 kg bag, would cover it as 1 × 50 kg + 4 × 10 kg + 1 × 5 kg + 1 × 1 kg for ₹40,806.00, but no fragrance ceiling is quoted for it in this series; check its product page or ask CSI before running an 8% blend in it. At this quantity, ask for a WhatsApp quote; no volume discount is published.

At list prices, the materials come to ₹279.52 per sellable candle, with the QC candles' cost spread across the 500. That excludes labour, packaging, freight and GST. The jar is the second-largest line after the wax, and neither its fill weight nor the right wick size is published: confirm both with a weighed, burned test candle before you commit to 505 of them. Converting a 5,000-candle quote into procurement shows the same sheet at ten times the scale.

Running the blend across 500 candles

If the 50:30:20 came from a small test and you are not yet sure it will hold at scale, scaling a 30 g test blend to 1,000 candles explains how to carry the ratio up without drift. For the single-oil version of a coffee run, 1 kg of coffee at 150 g gives the count, and the 5 kg reorder page shows how to set reorder points once the blend becomes a steady seller.
