Calculator
True cost per candle or bar, and your wholesale floor
Enter what goes into one finished unit and see the cost that survives cure loss, seconds and your own labor, plus the lowest wholesale price that still leaves room.

Calculators for small batch candle and soap studios
Two free tools for the arithmetic that decides whether a season is worth pouring: real cost per finished unit and how much your studio can actually cure and ship before a deadline.
Both tools run in your browser, keep nothing and ask for nothing. Put in your own wax price, fragrance load, vessel cost and studio hours, and the numbers change as you type. They use the same arithmetic WickAndWax applies to a batch record, so the figures line up with what the app would tell you from real pours.
The first is about money and answers the question a wholesale inquiry always raises: what does one finished unit cost you once rejected units and your own hours are counted, and what is the lowest price you can hold. The second is about time and answers the peak season question: given cure days and the hours you have, how many units can you honestly promise.

How many units can you cure and ship before the deadline
Put in your batch size, your finishing minutes and your cure rule, and see how many units your studio can honestly promise before the last shipping day.

The batch record and label release checklist
Four stages, twenty checks, covering everything that has to be captured between opening a wax carton and handing a labeled unit to a customer.
Why the wax and cure math stays open
Every small batch maker already runs these two sums by hand, usually on the back of a fragrance order slip. A fifty pound case of soy divided down to what one nine ounce tin holds, an eight percent fragrance load turned into ounces and then into dollars, the tins you set aside for wet spots counted honestly for once, and a cure countdown scratched onto the wall calendar beside the rack. That is studio arithmetic, not a trade secret, so neither calculator asks you to sign up for it.
They earn their keep even if you never open an account. Push a candle you sold all last season through the unit cost tool and the leak is usually the fragrance load or the minutes you spend trimming wicks and boxing, not the wax. Push your real bench hours and your own cure rule through the capacity planner and you come out with a last useful pour day and a ceiling you can quote to a shop buyer without guessing. Write both on an index card and tape it to the cupboard door above the pot.
When these figures stop being guesses
Both calculators run on numbers you typed from memory: a rounded cost per pound, a set aside rate that felt about right, a cure rule you mostly keep. The same arithmetic sits inside WickAndWax reading from recorded pours instead, so the cost per unit and the weekly ceiling come out of what the studio really did last month.
