I Reduced Fragrance from 10% to 8% and the Candle Still Smells Equally Strong — How Much Money Would That Save Across 1,000 Candles?

The sum: 4 g of oil out, 4 g of wax in

Fragrance load is a percentage of total candle weight (CSI's convention). A 200 g candle at 10% is 20 g of oil and 180 g of wax; at 8% it is 16 g and 184 g. You filled the same jar to the same line, so the 4 g of oil you left out became 4 g of wax. That is why the saving is not simply "4 g of oil": the wax that replaced it was not free.

Written as a formula you can reuse with any oil, wax and candle size: saving per candle = candle grams × (old load − new load) × (oil ₹/g − wax ₹/g). For 200 g and two points, the first two terms are 4 g. For a 150 g candle they are 3 g, so every figure on this page scales by three-quarters. If your oil is not from CSI, use your own price: at ₹4,000.00 a kilo with wax at ₹500.00 (worked example), the saving is ₹14.00 a candle and ₹14,000.00 per 1,000.

The full BOM at 10% and at 8%

The worked candle: 200 g of Woody Oud in Chunks, one Eco C2 wick, your own jar and box (labelled worked examples). Materials only; labour, freight, GST and marketing are excluded.

The candle costs ₹15.72 less, 5.2% of its materials. (The line-by-line BOM shows ₹15.72, one paisa under the ₹15.73 from the per-gram formula, because each line is rounded to the paisa; per 1,000 candles, use the formula.) Nothing the customer sees has changed: same jar, same box, same wick, same scent. That is what makes a load cut the cleanest saving in this series, if, and only if, the scent really is unchanged.

The same cut on eight CSI oils

The 4 g is constant; the rupees are not. Here is the same 10% to 8% cut priced on eight CSI oils at their 1 kg prices, all in stock on 4 October 2026. The wax claw-back (₹2.40 a candle with Chunks) is the same for every oil.

From the cheapest oil here to the dearest, the same two points are worth ₹21,080.00 more per 1,000 candles. Three practical points follow. First, if your 8% result is on a cheap oil, it is real but small: on Citrus Lemon it is ₹8,930.00 per 1,000. Second, the pack you buy matters as much as the oil: Jasmine priced at the 100 g bottle saves ₹14.80 a candle, at the 1 kg price ₹13.29, because a gram you do not pour is worth what you paid for it. Third, perfume-grade "inspired" listings priced well above these would show bigger rupee savings, but their pages quote perfume usage rates, not candle loads, so a candle test on them is a separate question.

Per month, per year, and what the number is not

The title asks about 1,000 candles. Whether that is a one-off festive run or every month changes the size of the decision, not the arithmetic. On Woody Oud:

What converts this into profit is volume; how a per-candle saving compounds at 1,000 a month is the subject of the ₹10-a-candle-at-1,000-a-month post. Here are three things the number is not.

It is not a saving if the candle is weaker

If 8% is in fact a little weaker and more buyers complain or return, the saving leaks away. Suppose (hypothetically) 3% more of 1,000 candles come back: replacing them costs ₹8,529.60 at the 8% COGS, or refunding them ₹20,970.00 at a ₹699.00 selling price (worked example). Either way that is a large bite out of ₹15,730.00, before the reviews. That is the whole case for the confirmation below.

It is not a reason to cut the price

An invisible cost saving is margin. If you pass it straight to the customer, you keep the risk and give away the reward. Pricing is a separate decision.

It is not doubled by a second, partial result

If only 9% had held, the saving would be half: ₹7,860.00 per 1,000 on Woody Oud. Do not average "8% on most candles" into a headline; bank the load that passed, oil by oil. How that sums across a range of oils is the range-wide per-oil load post.

Buying for 8%: the order that changes

A load cut shows up first on the purchase order, not the price list. At 1,000 candles of 200 g, your Woody Oud order falls from 20.0 kg to 16.0 kg a run, and the money you stop spending on oil is ₹18,124.80 gross; you spend ₹2,399.60 more on wax, which is how the net comes to ₹15,730.00. Three buying rules keep that saving intact.

Buy the new quantity, not the old one. If you still order 20.0 kg out of habit, the 4 kg you do not pour sits on the shelf as cash you have not saved yet. Re-set the reorder quantity on the day the 8% card goes live.

Check the ladder before you change pack. On Woody Oud the per-gram price is the same from 100 g to 1 kg, so smaller monthly use costs you nothing per gram. On Roasted Coffee the 1 kg is ₹42.00 cheaper than two 500 g packs, so stay on kilos. On Lavender the two are within ₹19.00. On 20 of the 78 oils CSI sells in both 500 g and 1 kg, the kilo costs more than two 500 g packs, so look before you assume.

Do not turn the saving into a bulk bet. CSI lists no fragrance pack above 1 kg; a 5 kg price from any supplier is a separate decision about cash tied up and how long the oil sits, covered in the 500 g-a-month, 5 kg question. The ₹15,730.00 on this page needs no bigger pack to happen.

Confirm "equally strong" before you bank it

"Still smells equally strong" is the claim the whole sum rests on, so it needs to survive four things: your expectations, your nose getting used to the scent, a candle that is still curing, and the last third of the jar. The ladder design (which loads to compare) belongs to the lower-load test design post; here is the minimum confirmation for a result you already have. The science of finding the lowest load that still throws is the lowest effective load guide, and the 7%-against-10% version for an expensive oil is the expensive-oil 7% against 10% test.

Cost: ₹489.37 of oil, ₹655.09 of wax, ₹432.00 of jars, ₹56.64 of wicks and ₹600.00 of labour (worked example), about ₹2,233.10. At ₹15.73 a candle, the first 142 candles poured at 8% repay it. It is cheap insurance. Change control for any load change, including what else to retest, is the full retest list when the oil formula changes.

The wick re-check at 8%

A two-point cut changes the melt pool's make-up, and higher loads are commonly linked to smaller or sootier flames, so lower loads can burn differently on the same wick (a tendency, not a rule). Before scaling to 1,000 candles, burn the 8% candles to the end on the wick you use now and compare with the 10% control: melt pool reaching the edge, flame height, carbon on the wick, soot, and jar heat in the final third. If the 8% candle now runs hot or the pool is deeper than before, the wick needs a bracket test, not a guess (whether a 10% to 8% cut needs a wick retest; the mechanism is in the 6%-to-10% flame-size post).

The oils and wax behind the numbers

The worked candle's oil and wax, plus two oils that show how the oil's price and pack change the answer. Chosen on page statements, price and stock on 4 October 2026; CSI publishes no throw data. The last column is the 10% to 8% saving per 200 g candle at that pack's price, net of Chunks wax.
