My Jar Supplier Increased Prices by ₹15 Per Piece — How Much Annual Profit Do I Lose if I Sell 2,000 Candles Every Month and Keep Prices Unchanged?

₹15.00 a jar, 2,000 candles a month, one year

The two numbers in your question are yours and this page uses them exactly as given: ₹15.00 a piece and 2,000 candles a month. One jar per candle, prices unchanged, and the arithmetic is as short as it looks. ₹15.00 × 2,000 is ₹30,000.00 a month. Twelve months of that is ₹3,60,000.00, and it comes straight off gross profit because nothing about what you charge has changed.

The annual figure is the one worth putting on paper, because ₹15.00 on a jar is the kind of increase that gets waved through. It does not feel like a decision. At your volume it is 24,000 jars a year, and ₹3,60,000.00 is a number most makers would fight hard for if it arrived as a single invoice. It arrives instead as ₹15.00, twenty-four thousand times.

Why a vessel increase bites harder than a wax one

Here is one candle costed on live CSI materials so the shares are visible. The reading carried throughout: 150 g of wax plus 12 g of oil at 8% of wax weight, 162 g poured. A fragrance load is a percentage of wax weight, which is how CSI product pages state it. The 150 g is a costing quantity, not a claim about what any jar holds — CSI publishes no fill weight for the vessels named on this page, so measure your own with water to your wax line and substitute your figure.

The vessel is 42.42% of this candle's materials — the largest single line, larger than the wax and the fragrance put together. That is the whole reason a jar increase hurts more than a wax one of the same size. Your ₹15.00 is 15.89% on the vessel and 6.74% on the candle, and the two figures are close precisely because the vessel is such a large share. A wax increase of the same rupee size would land much more softly, because the wax is only 34.20% of this specification.

Work out your own four shares once, on your own candle, and keep them written down. They tell you in advance how exposed you are to any future increase: a rise on a line that is two-fifths of your cost lands almost undiluted, and a rise on a line that is a tenth of your cost barely registers. Most makers shop hardest for wax, which on this candle is the line where an increase would matter least.

The price rise that puts it back

Your question says prices unchanged, which is the right way to size a problem — but it is worth knowing what changing them would take. The two rises below are set against an illustrative selling price of ₹450.00, chosen only to make the arithmetic visible. It is not a CSI figure, not a recommendation, and not advice about what to charge. Put your own price in and every row recalculates.

Restoring the rupees means earning the same ₹227.47 of gross profit per candle, which needs a rise of exactly ₹15.00 — 3.33% of an illustrative ₹450.00 price. Restoring the margin percentage means getting back to 50.55%, and the rule is that a price has to rise by the same percentage the cost did: your cost rose 6.74%, so the price rises 6.74%, which is ₹30.33, taking an illustrative ₹450.00 candle to ₹480.33.

The same jar, and two CSI vessels sold at the same size

Run your ₹15.00 against a real vessel and a real alternative and the shape of the problem changes. Clear Glass Jar with Golden Lid (150 gram) is ₹944.00 for a pack of ten, which is ₹94.40 a piece. Two other CSI vessels are sold at the same stated size — Black Glass Jar with Black Lid (150 gram) and Pink Glass Jar with Golden Lid (150 gram), both at ₹107.00 a piece. The whole spread across that family is ₹12.60, which is less than the ₹15.00 you have been asked to absorb.

That table contains the finding this page exists for. Inside a single size, the vessel market is narrow. Across CSI's 150 gram jars the published per-piece prices sit ₹12.60 apart, and the two alternatives are dearer rather than cheaper — moving to either of them at your volume would cost ₹3,02,400.00 a year rather than saving anything. So a same-size substitution cannot recover a ₹15.00 increase, and any page that tells you otherwise has not run the ladder.

The vessels that are genuinely cheaper are cheaper because they are different candles. 200ml Salsa Glass Jar with 63mm Lug Cap at ₹29.50 a piece is ₹64.90 under the jar you are using, and Mini Glass Jars at ₹21.24 is ₹73.16 under it — but those are different formats at different stated sizes, and they hold a different amount of wax, which changes the wax and fragrance lines as well as the vessel line. Changing to one of them is a decision to sell a different product, and it should be taken as one: photographed again, priced again, tested again.

The part of a jar's cost that is not the jar

A vessel's real cost to you is its price plus what it costs to arrive, and on glass that second part is large. A Pack of 10 of Clear Glass Jar with Golden Lid (150 gram) stores a packed weight of 3.0 kg. The published flat bands as at September 2026 give the following, and the interesting column is the last one, because it does not fall smoothly as the order grows.

Two rows in that table deserve a second look. At the smallest order the carriage alone is ₹27.00 a jar, which is most of the ₹15.00 increase you are worried about, before the jar itself is counted. Second, bigger is not automatically better: twenty jars in one 6.0 kg consignment is ₹630.00, while two 3.0 kg consignments are ₹540.00 — splitting is ₹90.00 cheaper at that weight, because 6.0 kg falls into a dearer band than two lots of 3.0 kg. At 12.0 kg the same thing happens: ₹1,200.00 in one against ₹1,080.00 in four, a difference of ₹120.00. At 15.0 kg the band works the other way and one consignment is the cheaper option at ₹24.00 a jar.

What this page leaves blank

Everything above is materials and inbound carriage. A finished, shipped, sold candle carries more than that, and none of the rest is a CSI product, so no honest number for it exists here. Copy the rows, fill in your own figures, and total the sheet as materials from CSI plus your own costs.

One blank deserves the last word. Breakage on the vessel line has just become more expensive, and it is the only blank on the sheet your increase touches. Every jar that chips in transit, cracks on the first pour or arrives with a lid that will not seat now costs ₹109.40 at the CSI rate used here rather than ₹94.40. At 24,000 candles a year, a breakage rate you have never measured is a number you can no longer afford to leave unmeasured. Count one month honestly, put the percentage in the sheet, and you will have earned back more than the ₹3,60,000.00 conversation is worth.
