The short versionDivide price by rated burn hours. Anything under $0.60 an hour is cheap, $0.60 to $1.00 is the normal luxury band, and above $1.20 you are paying for the object.
A $95 candle and a $31 candle sound like they belong to different worlds. Run the arithmetic and the picture changes: the $31 jar delivers 130 hours and the $95 glass delivers 60. One costs $0.24 an hour. The other costs $1.58. That is a factor of six, and it is invisible on the shelf.
The calculation
Cost per burn hour is the sticker price divided by rated burn hours. That is the whole formula. The reason nobody uses it is that burn hours are printed in small type on the bottom of the box, if they are printed at all.
The bands
| Band | Cost per hour | What you are buying |
|---|---|---|
| Mass market | Under $0.35 | Volume and throw. Paraffin, plain vessel. |
| Value | $0.35 to $0.60 | Decent wax, good looking glass, honest scent. |
| Luxury standard | $0.60 to $1.00 | Perfumery, better wax, a vessel worth keeping. |
| Object tier | Above $1.20 | Design, scarcity and a name. Performance is not the driver. |
What the number leaves out
Cost per hour is the best single number in this category and it is still incomplete. Three things it misses:
- Throw. A candle that only scents half your room is not cheap, it is inadequate. Two weak candles cost more than one strong one.
- Residue. A candle that leaves 11 mm of unburnable wax has already lost hours you paid for. The gap between the best and worst residue readings in our test is worth roughly six hours.
- The vessel. A ceramic body you use as a planter afterwards is worth real money. A printed glass jar is worth nothing the second the wax is gone.
That is why our value score is not simply the inverse of cost per hour. The cheapest candle in the index still posts the best value score, because $0.24 an hour is genuinely hard to argue with. But the brand at the top of the index costs three and a half times as much per hour and scores nearly as well on value, because it throws further, wastes less wax and leaves you an object you keep.
Questions
How do I calculate cost per burn hour?
Divide the price by the rated burn hours printed on the box. A $48 candle rated at 60 hours costs $0.80 an hour. Do not use weight, because multi-wick candles burn fuel much faster than single wick ones.
What is a reasonable price per hour for a candle?
Under $0.35 is mass market, $0.60 to $1.00 is the normal band for a luxury single-wick candle, and above $1.20 means you are paying primarily for design and brand.
Are expensive candles worth it?
Sometimes. The most expensive candle in our index posts the worst cost per hour and the best design score, and the second most expensive posts the cleanest burn we measured. If you value either of those, the premium buys something real. If you only want a scented room, it does not.
