I Want 25 Lavender, 25 Vanilla, 25 Coffee and 25 Sandalwood Candles — How Should I Calculate One Combined Wax Purchase and Four Separate Fragrance Quantities?

Wax adds up across scents. Oil never does.

A four-scent run has one rule that makes the arithmetic simple. Every candle uses the same wax at the same load, so the wax for all four scents is just the sum of four identical calculations — or one calculation for all 100 candles. Every candle uses a different oil, so each oil is calculated, buffered and rounded on its own. The title does not give a candle weight, so this page uses 200 g as a labelled working figure and shows what changes at smaller fills. Load is a share of the finished candle: each candle is 16 g of oil and 184 g of wax.

Each scent is treated as its own small batch, because it will be poured as one: 25 saleable candles, 1 pre-production check candle, a 3% reject allowance (25 ÷ 0.97 = 25.77 → 26), 5% pour loss on wax and oil, 2% breakage on glass and 1 spare wick — all labelled working assumptions. That gives 27 candles poured per scent and 108 in all.

The combined wax purchase

Summed across the four scents, the wax is 4 × 5,216.4 g = 20,865.6 g. Premium Coconut Soy Wax CSI 468 is listed at 500 g ₹325.00, 1 kg ₹650.00, 5 kg ₹3,185.00 and 10 kg ₹6,370.00 — ₹650.00 a kilo at the small sizes and ₹637.00 from 5 kg. The cheapest in-stock combination for the combined need is 2 × 10 kg + 1 × 1 kg, ₹13,390.00, leaving 134.4 g. Bought as four separate scent kits, each 5,216.4 g would round to 1 × 5 kg + 1 × 500 g at ₹3,510.00: ₹14,040.00 in all, ₹650.00 more, with 1,134 g left over instead of 134 g.

This page uses CSI 468 because its product page states a fragrance ceiling of up to 13%, a melting point of 50–53°C and pour at 58–60°C — enough headroom for a reader who decides one scent needs more oil, and handling figures you can follow. That is a reason to start here, not a verdict that it throws better than any other CSI wax; we publish no throw data. The two-fragrance post runs the same combine-or-split comparison across all four CSI container waxes.

Four separate oil quantities, rounded honestly

Each scent needs 453.6 g of oil. Rounded to the cheapest in-stock bottles of 50 g and above, every one of the four lands on a single 500 g bottle — but for different reasons. Lavender is ₹5.40/g at 100 g and ₹5.24/g at 500 g, so 500 g edges out 4 × 100 g + 2 × 50 g. Vanilla Bean and Roasted Coffee both step down at 500 g. Sandalwood has no choice: on the 4 October 2026 re-check its 15 g, 50 g and 100 g are out of stock, and only 500 g (₹2,513.40) and 1 kg (₹5,026.80) can be bought.

At 200 g the Sandalwood stock-out costs nothing: the 500 g bottle is what the need calls for anyway, at ₹5.03 a gram — the same rate the out-of-stock 100 g bottle carried. The picture changes as the candles get smaller, because the other three oils can step down into 100 g and 50 g bottles and Sandalwood cannot.

If you would rather pick a different woody oil than hold a large Sandalwood remainder, the choice of scent is yours — we make no claim that any of these smells like sandalwood, and CSI publishes no scent-profile or throw data. The table only shows which in-stock woody oils can be bought close to a small need:

The complete four-scent shopping list

Everything except the oils is bought once for all 100 candles. Jars are White Matte Glass Jar — CSI does not publish its fill weight, so weigh a test pour before ordering for 200 g. Wicks are Eco Candle Wicks Thin C1 as the example; CSI publishes no wick size per diameter, and four different oils may not all suit one wick, so the wick is the one shared line that waits for each scent's test.

The oils are the largest single block of spend after the wax and jars, and they differ a lot by scent: Vanilla Bean's 500 g is ₹3,840.00 and Roasted Coffee's is ₹1,890.00. That is why each oil is a separate decision, and why a scent you are unsure of should be tested from a small bottle before its 500 g is bought — the bulk-or-small post sets out that split. Note that Sandalwood has no small bottle to test from right now; if you have not used it before, ask on WhatsApp when the smaller sizes are expected back, or test with the 500 g and plan to use the remainder.

This page owns the four-scent split. Two fragrances, one wax pack compares combined and duplicate purchases in detail; 50 sandalwood candles at 8% is the single-scent Sandalwood list; 100 lavender candles is the single-scent Lavender list; minimum-leftover pack sizes tightens the oil rounding; and the 100-candle template has a line per scent. At larger scale, 1,000 candles split 40/30/20/10 runs uneven shares.
