In short A candle's materials cost is the sum of five lines and the interesting part is which of them is largest. For a 200 gram candle with wax at 800 a kilo, 16 grams of oil at 3,000 a kilo, a 15 wick, a 120 jar and 40 of label and box, the total is 383 — and the wax is only 160 of it while the jar is 120 and the fragrance 48. THAT ORDERING SURPRISES PEOPLE, and it is why switching to a cheaper wax rarely rescues a unit cost while switching jar supplier often does. MARGIN AND MARKUP ARE DIFFERENT NUMBERS AND THIS IS WHERE PRICES GO WRONG. Sell that candle at 950 and the margin is 59.7% — the share of the selling price you keep. The markup is 148.0% — how much you added on top of the cost. Both describe the same two numbers and they diverge fast: a 50% markup is a 33% margin, and a 50% margin is a 100% markup. Quoting one while thinking of the other is the commonest pricing error among small makers, and it always errs on the side of charging too little. COST PER BURN HOUR IS THE FIGURE THAT COMPARES HONESTLY. A small expensive candle and a large cheap one cannot be compared on price, but they can on what an hour of burning costs. Divide the unit cost by the burn time and you have the number a customer is actually buying, and the one worth putting beside a competitor's. AND THE LARGEST OMISSION IS DELIBERATE BUT IT IS STILL AN OMISSION. This is a MATERIALS cost. It does not include your time, the electricity for the melter, the wax left in the pouring jug, the test candles that did not work, packaging beyond what you entered, postage, or the fees on the sale. A unit cost that ignores labour is not a cost of production, and pricing directly off it is how small makers end up working for nothing. Add a realistic hourly figure for yourself before deciding a price is healthy. There is no currency here and no built-in price list: every figure is whatever money you typed, and the numbers only mean anything if they came from your own suppliers.

Frequently asked questions

How much does it cost to make a candle?
For a 200 gram candle with mid-priced wax, 8% fragrance, a wick, a jar and a label, around 383 in materials on the example prices here. The jar and the fragrance are usually larger lines than the wax.
What is the difference between margin and markup?
Margin is the share of the SELLING PRICE you keep; markup is what you added to the COST. Selling a 383 candle at 950 is a 59.7% margin and a 148.0% markup. Confusing them always leads to charging too little.
What margin should a candle have?
This page will not pick one for you. It reports the margin your price gives, and the figure only means something once labour and overheads are in the cost — which they are not here.
Why is my wax not the biggest cost?
Because wax is cheap by weight and containers are not. On most container candles the jar is the largest single line, which is why sourcing jars better moves a unit cost more than changing wax does.
What does this leave out?
Your time, electricity, wax lost in the jug, failed tests, postage and selling fees. It is a materials cost, not a cost of production.
Is there a limit on how often I can use the Candle Cost Calculator?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is my data uploaded anywhere?
No. The Candle Cost Calculator runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What do I get if I try it?
Enter 200 g wax, 16 g oil, a 120 jar, sold at 950 and the Candle Cost Calculator returns 383 per candle — 59.7% margin, 148.0% markup.
What is the Candle Cost Calculator used for?
The jobs it is built for: working out what a candle actually costs to make. Checking a price gives the margin you think it does. Comparing candles by cost per burn hour. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
When is the Candle Cost Calculator not the right tool?
Materials only, in whatever currency you typed. No price list, no labour, no overheads, and no allowance for waste or failed batches. Knowing where a tool stops being trustworthy matters more than the cases where it works.
Which values should I know?
The example candle is 383 in materials. Largest line is Usually the jar, not the wax. Margin at 950 is 59.7%. These are printed on the page itself, so you do not have to take them on trust.
Can I rely on this for exact work?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
