I Have a 1,000-Candle Corporate Order Split Across Four Fragrances — How Do I Calculate the Exact Quantity of Each Fragrance Oil?

The per-fragrance formula

The oil for each fragrance comes from that fragrance's own numbers and nothing else: candles in that fragrance × oil per candle, then that fragrance's own test candles, reject allowance and pour loss, then rounding to that oil's own bottles. At CSI's convention the load is a share of the finished candle, so a 180 g candle at a working 8% holds 14.4 g of oil and 165.6 g of wax. The split used here — 300 Bergamot Amber, 300 Sandalwood, 250 White Royal Oud, 150 Neroli — is an example of the kind a corporate client sends; replace it with yours and every line follows.

Each fragrance carries its own six test candles — three on each of two wick candidates — because a fragrance oil can change how a melt pool behaves, so the wick has to be proven per fragrance. That is 24 test candles across the order, and it is why the per-fragrance stack, not a single 1,000-candle stack, is the right starting point. The reject allowance is per fragrance too: if one fragrance rejects more often in your own history, give it a higher rate and the oil for that fragrance alone rises.

Rounding each oil separately — where the bottles differ

Rounding is where four fragrances really behave like four orders, because each oil has its own price shape and its own in-stock sizes. Bergamot Amber is ₹5.60 a gram at 50 g and 100 g and ₹5.44 at 500 g and 1 kg, so the cheapest cover mixes sizes: 4 × 1 kg + 1 × 500 g + 2 × 100 g. Sandalwood is the awkward one: on CSI's 4 October stock check its 15 g, 50 g and 100 g are out of stock, so only the 500 g (₹2,513.40) and 1 kg (₹5,026.80) can be bought, and a 4,679.0 g need rounds up to 5 × 1 kg — 321.0 g left over that a 100 g bottle would otherwise have trimmed. White Royal Oud is flat at ₹8.10 a gram from 100 g to 1 kg, so fine rounding costs nothing: 3 × 1 kg + 1 × 500 g + 4 × 100 g + 1 × 50 g. Neroli is flat at ₹6.66 from 100 g: 2 × 1 kg + 4 × 100 g.

Rounding four times costs something. Across the four oils the leftover after rounding is 392.3 g, worth ₹2,114.20 — more than a single-fragrance order of the same size would leave, because every fragrance rounds up on its own. That leftover is not waste: it is that fragrance's remake reserve, and the replacements post counts it as such. But it is the honest cost of a four-fragrance order, and worth putting in the quote.

What to buy before the client approves, and what after

A corporate order usually means four fragrances the client has to approve. The shared materials — wax, jars, stickers — are needed whichever fragrances survive, so they can be bought now. Each oil is bought in two parts: a test bottle now, for that fragrance's six test candles (89.0 g of oil with pour loss) and its approval sample, and the balance after written approval. For three of the oils the test bottle is 100 g. For Sandalwood it is 500 g, because nothing smaller is in stock — ₹2,513.40 at risk before approval, not ₹502.68.

Buying in two stages costs ₹0.00 more in oil than one order per fragrance, because each oil is rounded twice. That is the price of not holding ₹94,163.56 of oil the client might reject. The new-fragrance approval post works through when a large corporate order should wait for sign-off and when it should not, and the 500-favour hub shows the same two-stage pattern for a wedding.

The complete corporate order

The shared lines: 180.06 kg of Premium Coconut Soy Wax CSI 468 summed across the four fragrances (18 × 10 kg + 1 × 500 g, ₹1,14,985.00), 1079 White Matte Glass Jars (fill weight not published — weigh a 180 g test pour) and 1057 wick stickers. CSI 468 is the example wax because its page states a 13% ceiling and a published melting point and pour temperature for a team to follow — not a performance claim. Production wicks wait for the per-fragrance trial and may split into more than one line if the fragrances need different wicks.

Stage one is ₹1,99,004.72 and stage two ₹1,00,299.56. Per candle the oil alone ranges from ₹72.39 (Sandalwood) to ₹116.68 (White Royal Oud) at the 1 kg rate, so if the client pays one price across the four fragrances, the split decides your margin — a fact worth raising before they choose 600 of the dearest one. Branded packaging is the client's or your supplier's quote and stays out of the CSI subtotal.
