I'm Comparing Two Fragrance Oils Where One Costs Twice as Much but Works at a Lower Dosage — Which One Is Actually Cheaper per Finished Candle?
Share
Why isn't it simply 4% for twice the price? Because every gram of oil you leave out becomes a gram of wax, and wax costs money. The ratio here is 2.02×, so the naive answer is 3.96%; with the wax included it is 3.64%. The dearer oil has to do slightly better than ‘half as much’.
Does CSI say which oils work at a lower dosage? No. CSI publishes no dosage or throw data per oil. The dosage that matches your current candle is something only a side-by-side test in your wax and jar can tell you — the ladder test shows how.
What if my test says the dearer oil works at 6%? Then, using that example result, the dearer oil costs ₹208.60 of oil and wax per candle against ₹173.64 for the cheaper oil at 8% — ₹34.96 more. At 3.64% or below it would be cheaper. The worked example has the numbers.
The break-even dosage
Two candles made with different oils differ in only two lines: the oil and the wax. The wick, jar, lid and label are the same. So the comparison needs just those two lines. For a candle of weight W at load L, oil and wax together cost W × [L × p + (1 − L) × w], where p is the oil's price per gram and w the wax's. Set the dearer oil B's cost equal to the cheaper oil A's and solve for B's load:
Why the wax matters: if B works at a lower load, you pour more wax into each candle to keep the weight the same. That extra wax is a cost the naive comparison forgets. With Chunks at ₹0.60 a gram it is small but not negligible — it moves the break-even for our pair from 3.96% to 3.64%. With a dearer wax the effect is larger; with Natural Soy Pearl at ₹0.42 a gram it is smaller.
| Dosage of dearer oil | Its oil | Its wax | Oil + wax | Mango Coconut at 8% | Difference per candle | Cheaper per candle |
|---|---|---|---|---|---|---|
| 3% | 6 g | 194 g | ₹164.20 | ₹173.64 | −₹9.44 | Jasmine Coconut Spa Ceylon |
| 3.5% | 7 g | 193 g | ₹171.60 | ₹173.64 | −₹2.04 | Jasmine Coconut Spa Ceylon |
| 4% | 8 g | 192 g | ₹179.00 | ₹173.64 | +₹5.36 | Mango Coconut |
| 5% | 10 g | 190 g | ₹193.80 | ₹173.64 | +₹20.16 | Mango Coconut |
| 6% | 12 g | 188 g | ₹208.60 | ₹173.64 | +₹34.96 | Mango Coconut |
| 7% | 14 g | 186 g | ₹223.40 | ₹173.64 | +₹49.76 | Mango Coconut |
| 8% | 16 g | 184 g | ₹238.20 | ₹173.64 | +₹64.56 | Mango Coconut |
Read down the table: at 3.5% the dearer oil is fractionally cheaper; at 4% it is already dearer by ₹5.36, at 5% by ₹20.16 and at an equal 8% by ₹64.56. The break-even sits at 3.64%. Add the identical lines back — an Eco Thin C1 wick (₹5.90) and a White Matte Glass Jar (₹70.80) — and each candle's materials are ₹76.70 higher, but the difference between the two oils does not change.
The ratio depends on the pack
‘Twice the price’ is usually a comparison of two bottles. But the price ratio per gram can change with the size you buy, because a few oils have a real kilo break and most do not. Mango Coconut is one of the 24 oils where the kilo is at least 5% cheaper per gram (20.7%); Jasmine Coconut Spa Ceylon is priced flat. So the pair's ratio — and the break-even — depends on which sizes you compare.
| Size compared | Mango Coconut ₹/g | Jasmine Coconut Spa Ceylon ₹/g | Price ratio | Naive break-even (8% ÷ ratio) | True break-even |
|---|---|---|---|---|---|
| 15 g | ₹6.21 | ₹8.87 | 1.43× | 5.61% | 5.43% |
| 50 g | ₹5.00 | ₹7.98 | 1.60× | 5.01% | 4.77% |
| 100 g | ₹5.00 | ₹7.99 | 1.60× | 5.01% | 4.76% |
| 500 g | ₹3.96 | ₹8.00 | 2.02× | 3.96% | 3.64% |
| 1 kg | ₹3.96 | ₹8.00 | 2.02× | 3.96% | 3.64% |
From the 15 g tester to the 100 g the dearer oil is only about 1.4 to 1.6 times the price, so it needs to work at roughly 4.8% to 5.4% to break even. At the kilo it is 2.02 times, and the bar drops to 3.64%. If you are comparing a kilo of one against 100 g of the other, you are comparing sizes as much as oils. Always compare at the size you will actually produce from. Per-gram price breaks are rare across CSI's listed catalogue, so for most pairs the ratio is the same at every size — but check both oils' ladders before assuming it.
A worked example with your test result
CSI has not published dosage or throw measurements for any oil, and a claim that an oil ‘works at a lower dosage’ means nothing until you have seen it in your own wax, jar and room. So the worked example below uses a labelled example test result, the kind you would get from the ladder test in the next section: your blind scorers rated Jasmine Coconut Spa Ceylon at 6% as equal to Mango Coconut at 8%. Replace 6% with your own finding.
Finding the real dosage: the ladder test
The ladder test finds the lowest dosage at which the dearer oil matches your current candle. Pour the cheaper oil at your normal load as the reference, and the dearer oil at three or four lower loads. Score them blind. The lowest load that scores level with the reference is your tested dosage — the number that goes into the formula.
| Candle | Oil and load (hidden) | Cold throw | Hot 15 min | Hot 1 h | Hot 2 h | Level with reference? |
|---|---|---|---|---|---|---|
| Ref | Mango Coconut 8% | — | ||||
| 1 | Jasmine Coconut Spa Ceylon 5% | yes / no | ||||
| 2 | Jasmine Coconut Spa Ceylon 6% | yes / no | ||||
| 3 | Jasmine Coconut Spa Ceylon 7% | yes / no |
Keep every load inside the wax maker's stated maximum — Luxury Soy Wax Chunks are rated up to 13%, CSI 464 up to 10% — which a lower-dosage ladder always does. If none of the lower loads matches the reference, the dearer oil does not ‘work at a lower dosage’ in your candle, and the question is settled. If you want to go below the break-even, add a 3.6% candle to the ladder: that is the load at which the two oils cost the same.

What it is worth at volume
Differences of a few rupees a candle become real money over a production run. Here is the monthly difference over 500 candles for the dearer oil at several tested dosages, against Mango Coconut at 8%, at 1 kg rates. Positive numbers mean the dearer oil costs more.
| Tested dosage of Jasmine Coconut Spa Ceylon | Per candle vs Mango Coconut at 8% | Over 500 candles | Oil needed (before wastage) |
|---|---|---|---|
| 4% | +₹5.36 | +₹2,680.00 | 4.00 kg |
| 5% | +₹20.16 | +₹10,080.00 | 5.00 kg |
| 6% | +₹34.96 | +₹17,480.00 | 6.00 kg |
| 8% | +₹64.56 | +₹32,280.00 | 8.00 kg |
| Mango Coconut 8% (reference) | — | — | 8.00 kg |
At 6% the dearer oil adds ₹17,480.00 over 500 candles. Even at 4% it costs ₹2,680.00 more; only below 3.64% does it start to save. The last column is worth a glance too: a lower dosage means fewer kilos to buy and store, which matters for cash flow. The load-reduction post covers cutting one oil's load, and the 8% → 10% post the reverse; the supplier-discount post covers the different question of whether a bulk discount on one oil changes the answer.

Where this fits: the oil and wax lines compared here sit inside the full cost sheet. At a fixed selling price, the break-even dosage interacts with the oil cap in the ₹399 post and the ₹799 post, and at the luxury tier with the allocation in the ₹1,499 post. If the dearer oil wins your test and becomes a best-seller, the five-bestsellers post covers when to move it to kilos.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. Premium oils are often sold on the promise that you need less of them. We sell premium oils, and we still say plainly that we have published no dosage data for any of them, and that on the numbers the dearer oil has to perform very well to be the cheaper candle.
Oil and wax prices are CSI live pricing, pulled 24 September 2026. Wick and jar figures are those verified 10 September 2026. Break-even dosages, per-candle and batch figures are plain arithmetic on those prices, shown to two decimals. The 6% test result is an example, not a CSI measurement.
Only two fragrance ceilings are quoted in this data — Luxury Soy Wax Chunks up to 13%, CSI 464 up to 10% — and every load on this page sits within them. For help setting up a comparison between two oils, message us on WhatsApp at +91 7397976926.

Non-price figures and assumptions: Candles are 200 g finished weight; load is a share of finished weight. Oil + wax cost = W × [L × p + (1 − L) × w]; break-even L_B = L_A × (p_A − w) ÷ (p_B − w). The 6% dosage in the worked example and every dosage below 8% are examples or test points, not CSI data — CSI publishes no dosage or throw data per oil. The 500-candle run is illustrative. Labour, packaging, freight and GST are excluded. Load ceilings (13% Chunks, 10% CSI 464) are the wax makers' stated formulation maximums. Diwali 2026 falls on 8 November.
