Free candle burning time calculator to calculate how long a candle will burn using accurate formulas, burn rate, and wax weight.
A candle looks simple, but its burn time depends on science. Wax weight, wick size, and burn rate all matter. That is why we developed a free candle burning time calculator. This tool helps users calculate how long a candle will burn with accuracy and clarity.
Whether you are a candle maker, seller, or buyer, knowing burn time saves money and improves safety. Our calculator makes the process fast and stress-free.
A candle burning time calculator is an online tool that estimates how many hours a candle will burn. It uses wax weight and burn rate to produce accurate results.
Instead of guessing, users get clear calculations. This is helpful for handmade candles, container candles, scented candles, and pillar candles.
Our calculator works for both measured burn tests and estimated burn rates, making it useful for beginners and professionals.
Candle burn time is calculated using a simple formula. The key is understanding how fast wax burns per hour.
When a candle burns, wax melts and gets consumed by the flame. If you know how much wax burns in one hour, you can calculate the total burn time easily.
Candle burning time is calculated using this formula:
Burn Time = Total Wax Weight ÷ Burn Rate
In simple words, divide the total wax in the candle by how much wax burns per hour.
Burn time is measured in hours. Wax weight is usually measured in grams or ounces. Burn rate is measured in grams per hour.
This formula is used by candle makers worldwide and gives reliable results when accurate data is used.
The calculator instantly shows the candle burning time in hours with clear calculation steps.
Suppose a candle contains 240 grams of wax.
During a test burn, 24 grams of wax burned in 4 hours.
First, calculate burn rate.
Burn Rate = Wax Burned ÷ Time
Burn Rate = 24 ÷ 4
Burn Rate = 6 grams per hour
Now calculate total burn time.
Burn Time = Total Wax Weight ÷ Burn Rate
Burn Time = 240 ÷ 6
Burn Time = 40 hours
This candle will burn for approximately 40 hours.
The 3 hour rule for candles means you should not burn a candle for more than three hours at a time. Burning longer can overheat the container and increase fire risk.
This rule helps extend candle life and improves safety.
The 8:10 rule means a candle should burn evenly across its surface within 8 to 10 burns. This helps prevent tunneling and wasted wax.
Candle makers use this rule to test wick performance and burn consistency.
The 84 rule refers to the idea that one pound of wax should produce about 84 hours of burn time. This is an estimate and depends on wax type, wick size, and additives.
Our calculator provides more accurate results than this general rule.
Manual calculations can be confusing. Our free candle burning time calculator removes errors and saves time.
This makes it perfect for candle businesses, hobbyists, and DIY projects.
The candle burning time calculator is a simple but powerful tool. It helps users calculate candle burn time accurately using proven formulas.
Instead of guessing, you get real numbers. This improves safety, product quality, and customer trust.
If you make or use candles regularly, this calculator is a must-have tool.
It is very accurate when real burn test data is used. Estimated burn rates provide close results but may vary slightly.
Yes. Soy wax, paraffin wax, and beeswax all burn at different rates.
Yes. A thicker wick burns wax faster, reducing total burn time.
No. Fragrance throw may fade before the candle finishes burning.
Yes. It works for scented and unscented candles.
