My Fragrance Costs ₹5,000 Per Kg — How Much Money Do I Save Across 1,000 Candles by Using 7% Instead of 10% if Performance Remains Acceptable?

The money, and the four-line sum behind it

Take the load off the wax, because that is what a load is a percentage of. A candle holding 200 g of wax receives 20 g of fragrance at 10% and 14 g at 7%. The difference is 6 g a candle. Your oil is ₹5,000.00 a kilogram, which is ₹5.00 a gram, so those six grams are ₹30.00. A thousand candles later that is ₹30,000.00, and the run has moved from 20.00 kg of oil to 14.00 kg while the wax stays at 200 kg.

This page uses 200 g of wax a candle as its costing unit and says so here because your question does not give a candle size. That matters more than it looks: a fragrance load is a percentage of wax weight, so if you think of your product as a 200 g finished candle rather than a 200 g pour of wax, every gram figure on this page is a little high. The portable version of the answer, which does not care what size you make, is at the end of the next section.

Notice the shape of the staircase rather than only the total. Each single percentage point is worth ₹10.00 a candle on your rate, or ₹10,000.00 across the run, and the three points are simply that figure three times. There is nothing accelerating about the third point and nothing safe about the first — the arithmetic is perfectly linear, and the risk is not. Going from 10% to 9% is a change most candles absorb without anyone noticing; going from 8% to 7% is where a formula that was already marginal gives up. Price the steps as one sum and test them as three.

The size-free version: what three points are worth per gram of wax

A cut of three percentage points removes 3 g of oil for every 100 g of wax, whatever the candle. At your ₹5.00 a gram that is ₹0.15 for every gram of wax in the candle — ₹0.15 a gram, and that single figure answers the question for every size you make. Multiply it by the wax weight, then by the number of candles. A 150 g pour saves ₹22.50 a candle; a 300 g pour saves ₹45.00, exactly twice as much, because the whole relationship is proportional.

The same trick works for any other pair of loads. The rate per point is your oil price in rupees per gram, divided by a hundred, multiplied by the wax weight: at ₹5.00 a gram and 200 g of wax that is ₹10.00 a point a candle. Write that down once and you never have to rebuild the sum when somebody asks what 9% would cost instead.

The same cut on materials you can buy today

Your ₹5,000.00 a kilogram is your figure and may be a good one. To make the arithmetic checkable, here is the identical cut priced on live CSI stock in September 2026. The fragrance is Sultan’s Smoke, bought as the 1 kg pack at ₹7,999.00, which is ₹8.00 a gram. The wax is Premium Coconut Soy Wax CSI 468, bought as the 5 kg pack at ₹3,185.00, which is ₹637.00 a kilogram and puts ₹127.40 of wax in each candle. The wick is Eco Candle Wicks Thin (C1) at ₹5.90, the same rate at every pack size. The vessel is left out entirely, because it is your choice and it does not change when the load does.

Because this oil is dearer per gram than your ₹5.00, the cut is worth more here, not less: ₹47.99 a candle and ₹47,994.00 across the run. That is the general rule worth taking away — the value of a load cut scales directly with the price of the oil, so the expensive scents in your range are where a percentage point is worth testing and the cheap ones are where it barely repays the trouble.

One more CSI-specific figure worth having before you place the order, because it is the sort of thing a costing spreadsheet gets wrong by assuming. On this grade the rate per kilogram does step: Premium Coconut Soy Wax CSI 468 is ₹650.00 a kilogram in the 500 g and 1 kg packs and ₹637.00 in the 5 kg and 10 kg packs, a step of ₹13.00 a kilogram. On 200 g of wax that is ₹2.60 a candle and ₹2,600.00 across the run. Real, worth having, and about one-eighteenth of what the load decision is worth — which is the proportion to keep in mind when you are deciding where to spend an afternoon. Most CSI waxes do not step at all: the rate per kilogram is the same at every pack size on seven of the thirteen, and on three of them the larger pack works out slightly above the smaller one.

The condition: the burn test that earns the money

“If performance remains acceptable” is doing an enormous amount of work in that sentence, and the only way to settle it is to burn candles. What follows is a protocol you can run in a week and document in a notebook, designed so that the answer is a decision rather than an impression. It costs about ₹1,615.70 in CSI materials, which is roughly 34 candles' worth of the saving it is testing.

What being wrong costs, and why it is not symmetrical

Set the two outcomes side by side, because they are nothing like the same size. If 7% holds, you keep ₹47,994.00 on CSI materials, or ₹30,000.00 on your own rate, and the candle is otherwise unchanged. If it does not hold and you find out after the run rather than before it, a thousand candles carrying ₹2,45,290.00 of CSI materials are sitting in your storeroom smelling weaker than the ones people bought last time — before a single label, box, courier charge, hour of your labour or marketplace fee, none of which are CSI products and none of which this page will guess at. The materials alone are about five times the saving.

There is also a slower cost that no spreadsheet catches. A repeat customer who notices that this year's candle is quieter does not usually complain; they simply do not reorder, and you learn about it a quarter later as a number that will not go up. That is the real reason to run six test candles rather than to reason from a percentage: not because ₹1,615.70 is a lot of money, but because the thing you are protecting is not on the cost sheet at all.

If the test says 7% does not hold, the honest next question is whether the oil is the problem rather than the percentage. Throw at a given load is a property of the oil in the wax, and some oils genuinely need the top of their range. Where a page publishes a range, the lower of the wax ceiling and that range governs; where it does not, as with Sultan’s Smoke, the Premium Coconut Soy Wax CSI 468 ceiling of 13% of total wax weight is the only published limit and everything below it is a matter for your own testing. Ask on WhatsApp for documentation before you design a test around an assumption.

What the ₹30,000.00 deliberately leaves out

A load cut touches exactly one line: fragrance. The wax does not move, the wick does not move, the vessel does not move, and neither does anything below the materials line. That is worth saying out loud because a saving of ₹30,000.00 on a run can make a cost sheet look transformed when in fact one row changed. Copy the table below, fill in your own blanks, and total the run as materials from CSI plus your own costs.

Finally, and against this page's own commercial interest: do not let the ₹30,000.00 decide the formula. The reason to sit at 10% is that the candle needs 10% to smell the way your customers expect, and if that is true then three percentage points of margin is the most expensive money you will ever save. The reason to move to 7% is that six blind-burned candles said the throw holds. Those are the only two acceptable reasons, and neither of them is arithmetic.
