How Much Fragrance Oil Is Needed for 500 Candles?

Where the 8 kg comes from — and why it is the least interesting number on this page

Load, in this series as in the load guide, is the share of the finished candle that is fragrance oil. A 200 g candle at 8% is 16 g of oil and 184 g of wax; multiply by 500 and you have 8,000 g of oil and 92,000 g of wax. At 10% it is 10 kg and 90 kg; at 13%, 13 kg and 87 kg. One line of arithmetic, three usable answers.

Two conventions exist and they are not the same number. Several CSI oil pages phrase the load of total wax weight — Mango Coconut states "Candle usage rate 6-10% of total wax weight", and Cinnamon Vanilla states "Up to 13% of total wax weight". On that basis, 10% of 184 g of wax is 18.4 g of oil in a 202.4 g candle, which is 9.09% of the finished candle. This series keeps the finished-candle convention throughout so numbers compare across posts; if you work to the wax-weight convention, add roughly a tenth to your grams and be consistent. Mixing the two is a common reason two batches of one recipe disagree.

Same 8 kg, ₹41,926 apart

Four ways of buying 8 kg, all whole 1 kg bottles at listed September 2026 prices, all capable of scenting 500 × 200 g candles at 8%.

Read the middle two rows again. Moving from one oil to six costs ₹4,118.80 on the whole run — ₹8.24 a candle — the single best-value decision available to a 500-candle brand, because six scents sell in sets, give the customer a reason to come back, and stop one slow scent taking the month with it. Moving from the value-led six to the premium-led six costs a further ₹37,807.20, or ₹75.61 a candle. That is not a bad decision; it is a pricing decision. At a ₹450 retail price, ₹129.16 of fragrance leaves very little room once wax, jar, wick and packaging are in. At ₹1,200 in heavy glass with a printed box, it is the reason it can be ₹1,200.

How many scents should 500 candles carry?

Divide 500 candles by the number of scents and you get the per-scent commitment — what you are actually buying, and what sits in a cupboard if the scent does not sell. The floor to respect: a scent that cannot absorb one 500 g bottle within a quarter does not belong in a 500-candle run. It belongs on the trial list at 15 g or 100 g.

Four to six is the answer for almost every brand at 500 candles, and the reason is not fragrance — it is everything attached to a scent: its own wick check in your jar, its own cure window, its own label artwork, its own photograph, its own inventory line. The oil is the cheapest part of adding a scent. The launch-count guide reaches the same place from the shelf side.

Shares first, bottles second — and check the ladder before you round

Once the shares are fixed you have six awkward numbers like 1,333 g and 960 g, and a ladder of 15 g, 50 g, 100 g, 500 g and 1 kg. How you round matters, because the per-gram price does not behave the same way on every oil.

Of the 86 CSI oils listing both a 100 g and a 1 kg size with both in stock, 41 are priced at exactly the same rate per gram in both, and the median saving from stepping up to the kilo across all 86 is 1.2%. Chocolate Fudge is ₹396.48 per 100 g and ₹3,964.80 per kg, so ten hundreds and one kilo are both ₹3,964.80. On a stepped oil the gap is real money: Mango Coconut is ₹500 per 100 g against ₹3,964 per kg, so 1,200 g as one kilo plus two hundreds is ₹4,964 while twelve 100 g bottles are ₹6,000 — ₹1,036 more for identical oil.

Citronella is the extreme case, worth knowing before you plan a mosquito-season line: its listed 100 g is ₹767 against ₹2,891 for the kilo, so the kilo is 62% cheaper per gram. Four oils step by 15% or more, twenty-three by 5–15%, and 41 not at all. The rule, worked through in the guide to moving into kilos: round up to the kilo on anything that steps; on flat oils round to whatever leaves the fewest part-used bottles.

A six-scent portfolio for 500 candles, costed to the bottle

A worked example, not a prescription: six oils spanning price tiers and scent families, all in stock in September 2026, all with stated notes. Shares are 30 / 20 / 15 / 15 / 12 / 8 of the 8,000 g.

That is ₹82.02 of fragrance per candle. Two details in the total matter. The plan buys 8,100 g to pour 8,000 g, so the spill allowance arrived free from rounding. And the same 8,000 g at pure 1 kg rates would be ₹40,169.73, so the ladder charged ₹837.87 — about 2% — for buying part-kilos. Chocolate Fudge takes a full kilo rather than 960 g because its per-gram price is flat: same rate, 40 g spare, five fewer bottles to handle.

For scale: 92 kg of Luxury Soy Wax CSI 464 is nine 10 kg packs plus two 1 kg packs, ₹46,680.80, and 500 Eco Candle Wicks in Thin (C1) is ₹2,950. Oil, wax and wick come to ₹88,713.20, so fragrance is 8% of the mass and 44% of the material cost — which is why the portfolio decision deserves an afternoon rather than a guess.

Placing the order in one pass

Five steps, in this order. Doing them out of order is how makers end up with nine bottles of one scent and none of another.

What a wrong split actually costs

Take the anchor in the worked plan: 2,400 g of Cinnamon Vanilla for 150 candles at ₹4.5548 per gram. Sell 100 instead of 150 and 800 g sits unused — ₹3,643.84 of oil. Sell 60 and it is 1,440 g, ₹6,558.91. Sell 40 because you misjudged the direction and 1,760 g is idle: ₹8,016.45 of the fragrance budget in a cupboard rather than in a customer's hand. None of it has gone bad — no CSI page states a shelf life, so nobody can honestly tell you it has expired — but cash that is not moving is what kills small candle brands, not spoilage.

The second half of the fix is a cut rule written before the run: any scent that has not sold 40% of its allocation eight weeks after launch loses its slot in the next order, and its share goes to whichever scent sold out first. A rule decided in advance survives the attachment you will develop to the scent you personally like best — reliably, the one that sells slowest.

Then the run-level sanity check. If your honest estimate is that 500 candles will take six months to move, you are not planning a 500-candle run — you are planning two 250-candle runs, so buy oil for the first and keep the cash for the second. The cadence version of this argument, for a thousand-candle month, is in the 1,000-candle guide.
