I Received My First 500-Candle Order — What Should I Calculate Before Saying Yes to the Customer?

Your order, written as numbers

Your title gives one figure: 500 candles. Before any calculation, write down the others. Where the client has not said, write your assumption and send it back for confirmation. The full intake questionnaire is the client-questions post; this page needs only the seven lines below. Everything except the 500 is a labelled worked example: replace each one with yours.

Two of those lines are where first orders usually go wrong. The fill weight: a 200 g candle is 200 g of finished wax and oil, not a 200 ml jar (the 200 ml versus 200 g post). The daily rate: if you have never poured more than 40 candles in a week, "30 a day" is a guess, and a guess is not an input. Time one full day before you reply.

Calculation 1: is the candle already proven?

This is a yes-or-no calculation, and it comes first because a "no" changes everything after it. The candle is proven only if all five are true: the same wax, the same oil at the same load, the same wick, the same jar, and the same dye (or none), burned together through the whole jar in still air, with an acceptable melt pool, flame, soot and jar heat in the final third. "I've made rose candles before" is not proof if the jar is new.

If every row is a yes, carry on to the purchase sheet. If any row is a no, your answer to the client is a development date, and the time that takes (sample oil, load ladder, cure, full-life burns, approval) is the new-fragrance development post. Count that in calendar time, not effort: pour, then cure (the 25 CSI oil pages that state a cure give 48–72 hours for soy, and many makers judge throw at day 3, 7 and 14), then full-life burns in sessions of three to four hours. In our judgement that is one to two weeks before a client should see a sample, whatever the deadline. The steps that cannot be squeezed even when the client is in a hurry are the never-skip post.

Calculations 2 and 3: materials and pieces, rounded to packs

This is the calculation most first-timers get half right. They work out 92 kg of wax and 8 kg of oil, order exactly that (₹55,108.00 of wax at the kilo price and ₹24,544.00 of oil), and run short on day 11. The full buffer method is the purchase-sheet post; whether to plan for 500 or 525–550 is the 500-versus-525 post; and the oil line on its own is the 500 × 200 g wax-and-oil post. Here is the sheet for this order.

The three buffers, kept separate

Planned extras are candles you intend to make and not sell: 4 QC retains, kept with their lot numbers until well after delivery, and 6 burn-check candles pulled from different days of production. The loss buffer covers candles you will reject: sinkholes, off-centre wicks, chipped jars, a bad pour. For a first order of this size you have no reject history at 500, so this sheet uses 5%, a little above the 4% the 1,000-candle hub uses, and you record what actually happens for next time (the 5%-more-than-planned post). The heel (1% of the mix) is wax left in the pot and pitcher that never becomes a candle. Pieces (wicks, jars, boxes, labels) get a 2% breakage and defect allowance of their own. Nothing is buffered twice.

₹260.61 per saleable candle includes every buffer, but it excludes labour, freight, GST, your own time and overheads. Against the naive "92 kg and 8 kg" order, the extra lines cost real money; they also cost far less than running short and buying 5 kg in a hurry on day 11, with a second lot of oil that may not match the first.

Three pack decisions that change the total

Wax: the biggest bag is not the cheapest. Luxury Soy Wax Chunks cost ₹5,999.00 for 10 kg, which is ₹9.00 more than two 5 kg bags (₹2,995.00 each) and ₹9.00 more than ten 1 kg bags. For 100 kg, ten 10 kg bags cost ₹59,990.00; twenty 5 kg bags cost ₹59,900.00. The 500 g bag is cheapest of all per kilo (200 of them would be ₹59,800.00, another ₹100.00 less), but 200 bags is a lot of opening and weighing for a saving that small. We sell the 10 kg. For this order, buy the 5 kg.

Oil: check per gram before you assume. On British Rose the 1 kg is ₹3.07 a gram against ₹3.19 for 500 g, so 9 × 1 kg (₹27,612.00) beats 18 × 500 g (₹28,674.00) by ₹1,062.00, and also beats 8 × 1 kg + 2 × 500 g (₹27,730.00). On several other CSI oils the 1 kg costs the same as two 500 g bottles, or slightly more; a few perfume-grade listings are flat per gram from 50 g to 1 kg. Check the per-gram column on the oil you actually use. CSI lists no oil pack above 1 kg.

Pieces: flat per piece, so buy the smallest covering combination. Eco C2 wicks are ₹9.44 each in every pack size, so 550 wicks (500 + 50) at ₹5,192.00 beat a 1,000-pack you would mostly store. The stickers are the opposite case: one 1,000 roll at ₹699.00 is ₹127.00 cheaper than two 500 rolls, though it is a larger sticker. The box is a flat ₹22.42 at 50 or 100.

Calculation 4: the days it really takes

Dividing 500 by 28 gives 17.9 a day, and it is wrong in the client's favour and against yours. Take out the days you cannot pour: Sundays (on a 6-day week), the set-up days while the PO, advance and materials arrive, and the tail after the last pour, when candles set, are checked and packed. A 72-hour set before lidding is a planning judgement: 25 CSI oil pages that state a cure give 48–72 hours for soy before burn testing, and British Rose's page states none in the text we captured.

So the decision rule for the date is simple: if your proven rate is at least 29 a day, accept the 28-day date; if it is lower, quote the date your rate gives you. At 30 a day you can pour 570 in 19 days, enough for 535 with one working day to spare. Feasibility for bigger jumps, where the rate has to multiply rather than nudge, is the cluster hub, the 1,000-in-21-days post.

Check the stations behind the rate, not just the pot. Thirty candles a day held for about four days (72-hour set plus a day waiting to be packed) is about 120 rack positions. Packing 500 at a worked-example 2.5 minutes a candle is 20.8 hours: pack each day's candles as their 72 hours end, rather than leaving every box to the last two days.

Calculations 5 and 6: cash before the advance, and price against true cost

Calculation 5: the cash that leaves before the first pour

Almost every rupee on the purchase sheet is spent before production starts: ₹1,30,304.00 on days 1 and 2 in the worked example. The client's money arrives in two pieces, the advance and the balance. At a worked-example ₹450.00 a candle the order is worth ₹2,25,000.00; a 50% advance is ₹1,12,500.00. That covers 86.3% of the materials, so ₹17,804.00 of your own money is tied up from day 1 until the balance of ₹1,12,500.00 arrives on delivery, before you have paid anyone to help. An advance of about 57.9% would cover every material on the sheet.

How big the advance should be, and what it must cover (at least the client-specific materials you could not reuse), is the advance post and the non-reusable-materials post in the next cluster (6364). For this calculation you need only one figure: the cash gap you can fund without risking your other orders. If you cannot fund ₹17,804.00, ask for a larger advance or split the purchase (wax in two deliveries costs nothing extra per kilo at CSI's flat pricing; see the split-purchasing post).

Calculation 6: your price against your true cost

Materials are not the whole cost. Add a helper for the 23 working days (worked example ₹600.00 a day, ₹13,800.00) and freight to the client (worked example ₹6,000.00), and the true cost per saleable candle is ₹300.21, still before GST, your own time, overheads and the test candles you made to win the order. The method for every line, including failed batches, is the true manufacturing cost post.

Two readings matter. First, the floor: the lowest price that pays for materials, help and freight is ₹300.21. If the client counters at a worked-example ₹350.00, you keep ₹49.79 a candle for your time and every risk on this page, which is thin for a first order. Second, the mix: wax is 46.0% of materials and oil 21.2%, while the jar alone is 18.9%. If the price needs to come down, the jar and the box are bigger levers than the wax (the which-component-first post).

Calculation 7 and the "yes, if…" reply

The last calculation is delivery: who packs, how the cartons travel and who pays. Five hundred candles in 550 boxes are bulky; couriers commonly bill on actual or volumetric weight, whichever is higher, so check your courier's terms and put freight in the quote, or state that it is extra. One address or many changes everything; ask now, not on day 25. Then write the reply. Run the seven calculations in this order; each can end it.

Every number in that reply comes from a calculation above. If any condition fails (the sample is not approved, the advance is late), the date moves by the same number of days. Say that once, kindly, in the reply. It saves an argument in week three. The scored go / no-go version of this decision is the decision-matrix post.

What to buy, and what not to buy yet

Five items, chosen on page statements, price and stock on 7 October 2026. CSI publishes no burn or throw data, so nothing is ranked on performance, and each card assumes the item is already part of your proven candle. Each one says when not to buy it.

Argued against our own interest: do not buy any of the five in bulk before the client has approved the sample in writing and paid the advance. Before that, buy only what the sample needs: 100 g of oil, a 10-pack of wicks, a few jars. If the order falls through, you want to be holding ₹342.20 of rose oil, not 9 kg. And if your proven wax is a different one, such as Luxury Soy Wax CSI 464, stay with it: a cheaper wax in the middle of your first big order is a reformulation, not a saving. Tools for the run, if you lack them: a Weighing Scale and a Pen Thermometer (₹354.00 each, both in stock on 7 October 2026).
