Candles add warmth and ambiance to any space, but knowing how long a candle will last helps you plan your usage and manage your inventory if you make candles for sale. Burn time indicates how many hours of light or fragrance you’ll enjoy before the candle is spent. This calculator provides a quick estimate based on the amount of wax and the rate at which it burns. Whether you’re setting up a romantic dinner or selling handmade candles at a craft fair, understanding burn time ensures you get the most from each candle.
Several elements influence how quickly a candle consumes wax. Wick size and material determine how much fuel the flame draws, while the type of wax—such as soy, paraffin, or beeswax—affects how fast it melts. Additives like fragrance oils and dyes can also alter burn characteristics. Even the ambient temperature and air currents in a room make a difference. While this calculator uses an average burn rate you supply, keep these variables in mind when testing your own candles to refine the estimate.
Begin by weighing your candle to determine the total wax content. Many store-bought candles list their weight on the label, while handmade creations can be weighed on a kitchen scale. Enter this value in grams for the most accurate result. Next, conduct a test burn to determine how many grams of wax are consumed per hour. This involves measuring the candle’s weight before and after a set burn period. Divide the amount of wax used by the hours burned to find the burn rate. Enter that figure, press Calculate, and the script will estimate the total hours the candle should last from start to finish.
If you’re organizing a special event, knowing the burn time helps you decide how many candles are needed to keep the atmosphere glowing all evening. For candlemakers, burn time is an important marketing point and can influence pricing. Customers appreciate knowing how many hours of light or scent they’re purchasing. By accurately estimating burn time, you build trust and encourage repeat business. This calculator makes it easy to provide that information with confidence.
For scented candles, burn time relates closely to fragrance release, often called “scent throw.” A slow, steady burn allows the candle to release aroma evenly without overwhelming the room. Conversely, a candle that burns too quickly might smell strong at first but fade rapidly. Use this calculator to gauge whether your candle’s wick and wax combination provides a balanced burn that maximizes fragrance enjoyment throughout its lifespan.
Accurately estimating burn time helps prevent unattended candles from burning too long. Always keep candles on a heat-resistant surface away from flammable items, and never leave them burning when you leave the room or go to sleep. Trimming the wick to about a quarter inch before each use promotes an even burn and minimizes soot. If you notice the flame flickering excessively or the wick mushrooming, extinguish the candle, trim the wick, and relight it once the wax solidifies.
To maximize burn time, choose an appropriate wick size for your candle’s diameter. A wick that is too large will burn through wax quickly, while one that is too small may tunnel and waste wax around the edges. Experiment with different wick materials—cotton, wood, or braided blends—to find the best match for your wax type. Keeping the candle away from drafts and out of direct sunlight also helps maintain a consistent burn rate, extending the life of your candle.
Container candles, such as those in glass jars, usually burn longer because the container shields the flame from air movement. Pillar candles exposed to open air may burn faster. When calculating burn time, consider how the container design or lack thereof affects airflow and heat distribution. If you make candles in multiple shapes or sizes, test each style separately to determine accurate burn rates.
Many people prefer natural waxes like soy or beeswax for their cleaner burn and renewable sourcing. These waxes often burn slower than paraffin, yielding longer burn times. However, they may require different wick sizes to achieve optimal performance. This calculator can help you compare how various wax types influence burn time, allowing you to fine-tune your formulas for the best combination of eco-friendliness and longevity.
The Candle Burn Time Calculator is a handy tool for hobbyists and professional chandlers alike. By inputting wax weight and burn rate, you can approximate how many hours of light and fragrance a candle will provide. Use it when planning events, setting prices, or refining your candle-making process. With a better understanding of burn time, you’ll enjoy every candle to the fullest and create products your customers will love.
