Candle Burn Time Calculator
Estimate how many hours a candle will burn from its wax weight and burn rate.
Inputs
227g ≈ 8 oz, a common candle size.
Typical burn rate is around 6-9 grams/hour, depending on wax type and wick size.

What is the Candle Burn Time Calculator?
Candle burn time is roughly total wax weight divided by how fast it burns — burn rate itself varies by wax type (soy, paraffin, beeswax), wick size, and container shape.
How to use it
- 1 Enter the candle's total wax weight.
- 2 Enter (or estimate) the burn rate — check the product listing or use a typical 6-9 g/hour range.
Worked examples
Limitations
- •Burn rate isn't perfectly constant — it's typically a bit faster early on and slower as the candle nears the bottom, so this is an average-based estimate.
Frequently asked questions
Why do candles burn faster the first time?
A properly formed 'memory ring' (full melt pool) on the first burn helps prevent tunneling — burning a candle for too short a time initially can create an uneven wax pool that wastes wax on later burns.
