About this calculator
Total burn time is estimated as wax weight ÷ burn rate (grams per hour), where burn rate depends mainly on wick size and wax type — a thicker wick or softer wax (like soy or paraffin blends) melts and consumes wax faster than a thin wick in a harder wax such as beeswax.
Candle makers use this to label expected burn time on a new product and to compare how a wick change affects it before a full burn test, while shoppers and hobbyists use it to estimate how long a candle will actually last based on its listed wax weight, since burn rate — not just size — is what really determines candle life.
