Candle & Fragrance Calculators
Free, practical tools for a beautifully scented home — estimate a candle’s burn time, measure a fragrance load, dilute essential oils, dose a diffuser, size wax melts to a room, and pick the right wick. Educational tools for enjoying and making home fragrance, not medical or professional advice.
Candle Burn Time Calculator
Estimate how long a candle will burn from its wax weight, wick count, and burn rate — total hours, the number of evenings it covers, and the wax used each session
Fragrance Load Calculator
Turn a wax weight and a load percentage into the exact fragrance oil to add in grams and ounces, with a safe-maximum check so you never over-scent a batch
Essential Oil Dilution Calculator
Convert a target dilution and carrier volume into the drops of essential oil for a room, reed, or base-oil blend — for scent and enjoyment, not medical use
Diffuser Drops Calculator
Get the right number of oil drops for your diffuser from the water-tank capacity and room size — a scent that fills the space without overpowering it
Wax Melt Quantity Calculator
Size your wax melts to the room — how many cubes to melt at once and roughly how many scent-hours they give for flame-free fragrance
Candle Wick Size Guide
Find a starting wick size from your container diameter and wax type — CD and ECO recommendations from a curated table, adjusted for soy, paraffin, coconut, and beeswax
