I Can Save ₹1,000 Per Kg by Buying 5 Kg of Fragrance at Once — How Many Candles Do I Need to Sell Before That Inventory Investment Pays Off?

What the ₹5,000 is, and what it is not

Your figures first, kept exactly as you gave them. A saving of ₹1,000.00 a kilogram across 5 kg is ₹5,000.00. That is the whole prize and it is worth having. But it does not arrive as ₹5,000.00. It arrives as a slightly lower cost on every candle you pour from that drum, at the rate of ₹16.00 a candle — ₹1,000.00 a kilogram spread over the 16 g each candle takes.

So the word payback needs unpicking before the arithmetic starts. Nothing here pays back in the sense a machine does. You have not bought an asset that generates money; you have paid earlier, and in larger lumps, for a material you were going to buy anyway, in exchange for a lower rate. The only way the ₹5,000.00 reaches you is by pouring all 5 kg. Five kilograms at 16 g a candle is 312.5 candles — call it 312 whole candles of one single scent.

And there is a second number nobody puts on the invoice. Those 312 candles need wax behind them: 200 g each is 62.5 kg of wax. On Luxury Soy Wax CSI 464 at ₹507.40 a kilogram, that is another ₹31,712.50 of material for the same run — more than the oil. A fragrance buying decision is never only a fragrance buying decision, and the cash it implies is roughly double what the fragrance invoice says.

The answer: 261 candles

Here is the comparison that answers the question properly. Two ways of buying: take the 5 kg now at the discounted rate, or buy only what you need, when you need it, at the full rate. Taking the 5 kg costs ₹24,995.00, fixed, whatever happens next. Buying as you go costs ₹5,999.00 for every kilogram you actually pour and nothing for the kilograms you never reach.

Set them equal and solve for the quantity. ₹24,995.00 ÷ ₹5,999.00 a kilogram is 4.1665 kg. Pour more than that and the 5 kg purchase was cheaper. Pour less and you would have been better off buying as you went, discount or no discount. In candles, at 16 g each, 4.1665 kg is 260.4 — so the working answer is 261 candles of that one scent, and everything after that is profit on the decision.

Notice what that means as a fraction. You have to use 83.3% of the drum. Not most of it — nearly all of it. The reason is structural: your saving is ₹1,000.00 against a rate of ₹5,999.00, which is about 16.7% off, and a discount of that size is wiped out by wasting a sixth of what you bought. Whenever someone offers you a bulk rate, divide the discount by the full rate and you have the fraction you are allowed to waste. Here it is 16.7%, or 0.833 kg of the 5 kg.

The shape of that column is the thing to remember. It is not a gentle slope. From 5 kg down to the crossover the advantage bleeds away slowly, and then it collapses: pour 3 kg of the 5 and you paid ₹8,331.67 a kilogram for fragrance whose list rate is ₹5,999.00 — ₹2,332.67 a kilogram worse off, for the privilege of having taken a discount. The curve is a hyperbola, which is another way of saying that the last kilogram in the drum is the one carrying the entire argument.

How long 5 kg lasts at your own sales rate

The crossover of 261 candles answers whether the purchase is right. Your sales rate answers when. Put your own monthly figure for that one scent into the table below and read across: the months of cover, the point at which the saving has actually been earned, and how much of the ₹5,000.00 lands each month while you wait.

Two things fall out of that table. The first is that the saving per month is small at every realistic rate: even at 150 candles a month it is ₹2,400.00, which is the scale of a modest expense line rather than a transformation. The second is that the months-to-crossover column is the one that matters for cash. At 40 candles a month you are 6.5 months from the point where the decision was worth taking — and a lot can change about a scent's popularity in 7 months.

Set that against the Indian selling year, because it is not uniform. Diwali 2026 falls on 8 November 2026, and a 14 to 21 day cure plus delivery puts the festive pour around mid-October; weddings, Rakhi and corporate gifting bunch similarly. A scent that sells 40 a month on average may sell 150 in October and 12 in February, which changes cover from a single number into a seasonal question. Buy the drum ahead of the season it serves, not in the quiet month when the offer happens to appear.

What CSI's own fragrance ladder actually does

Your title assumes a rate that falls with quantity. It is worth being exact about what happens on this store, because the answer is not the one a bulk-buying article usually gives. Run the rate ladder on Wild Berries and the four published packs come out at ₹5.98 a gram at 50g, ₹5.99 at 100g, ₹6.00 at 500g and ₹6.00 at 1kg. The rate does not fall as the pack grows; the smallest pack is fractionally the cheapest per gram, and the largest is fractionally the dearest. CSI publishes no per-kilogram quantity ladder, and 1 kg is the largest published pack of this oil, so 5 kg is five 1 kg packs at ₹29,995.00.

Follow that to its logical end and it produces a genuinely odd-looking result, so here is the whole calculation rather than a slogan. Five kilograms bought as one hundred 50g packs is 100 × ₹299.00 = ₹29,900.00, which is ₹95.00 less than the same 5 kg in 1kg packs. Then check the parcel, because that is where it turns around: a hundred 50g bottles store 10.0 kg of packed weight and the cheapest published band covering that is ₹800.00, while five 1kg bottles store 5.5 kg and cost ₹630.00. Landed, the small packs are ₹30,700.00 and the kilogram packs are ₹30,625.00 — the kilograms win by ₹75.00. The lesson is not that either is clever. It is that the rate ladder alone never settles a buying question.

What CSI does publish, and what is genuinely worth planning an order around, is three spend-based codes: HAPPY5 at 5% over ₹5,000, BIZWIZ8 at 8% over ₹12,000 and YAY10 at 10% over ₹20,000. They are order-value discounts, not quantity breaks — they depend on what the basket comes to, not on the pack you choose. A 5 kg fragrance order at ₹29,995.00 sits past the YAY10 threshold, so the code is worth ₹2,999.50 on it, which is ₹599.90 a kilogram and brings the order to ₹26,995.50. That is a real number, it is less than the ₹1,000.00 a kilogram in your question, and it is the honest comparison rather than a promise of a ladder that does not exist. For a genuinely large consignment the route is a quote on WhatsApp.

Where the certain saving actually is

Everything above is conditional on demand. There is one saving in a 5 kg purchase that is not: the parcel. CSI's delivery charges are published flat rates by weight band, and bands are set by the stored packed weight. The 1kg pack of Wild Berries stores 1.1 kg. Ordered one at a time over five months, each parcel falls in a band costing ₹180.00 on Standard Shipping — ₹900.00 in all. Ordered together, 5.5 kg falls in a single band at ₹630.00. The difference is ₹270.00, as published in September 2026.

Carried into the candle that is ₹0.86 each across the 312 candles the 5 kg makes — small, but it is money you keep whether the scent sells or not, and it is the only line on this page with that property. Two reviews on the store say plainly that delivery charges feel high. That is a fair criticism and consolidating is the honest answer to it, not a claim that the charges are small.

Two cautions, because consolidating is not a law. The bands have edges and they bite in both directions: Standard Shipping stops at 15 kg, so a very large consignment can cost more in one parcel than in two, and a weight that just crosses a band edge can cost more than a heavier one that sits inside the next. Check the weight you are actually shipping before you decide that bigger is cheaper. And the stored packed weight is the figure that bills, not the label — a 1 kg bottle of oil ships at 1.1 kg here, and a 500g bottle at 0.6 kg.

Running it on your own figures

One refinement worth adding if you want it. The step above ignores the cost of holding the cash, which is real and which this page will not put a number on because it is not a CSI cost and it is different for every business. If you do have a number for it — an overdraft rate, a supplier credit you are giving up, a stall booking you cannot afford — add it to the ₹24,995.00 before dividing. It moves the crossover up, never down, which is worth knowing before you round the answer in your own favour.

What this page will not put a number on

Every rupee figure here is either your own stated saving or a live CSI price in September 2026. The rest of an inventory decision is real and no supplier can price it for you. Copy these rows into your own sheet, fill them from your own records, and total the page as materials from CSI plus your own costs.

The wastage row deserves its sentence, because it interacts with everything above. This page has assumed that every gram of the 5 kg reaches a candle. It will not: oil clings to the bottle, a batch gets abandoned, a measurement goes wrong. If your real figure is 3%, then 5 kg is 4.85 kg of usable oil and 303 candles rather than 312, and the crossover of 261 candles has become a larger share of what you can actually pour. Measure it once across a full batch and use your own number — it is worth more than any figure printed here.
