A refill calculator gives a projection from the numbers you enter. The tablets you can count are a separate observation. When the two disagree, compare the inputs before changing a stock record.
Separate the count from the forecast
Write down two numbers: the units physically present and the balance predicted by your record. Add the date and time of the check. A count made before the morning dose cannot be compared directly with an estimate made after it. Keep the comparison for one medicine and one person at a time.
An unexplained difference is a question about the record. It does not establish that somebody took an extra dose or missed a dose. The stock figure alone cannot tell you what happened.
Use the same unit on both sides
Check whether you entered tablets, packs, millilitres or another unit. Three unopened packs containing 20 tablets each represent 60 tablets, not three tablets. If an opened pack contains eight tablets, count those separately: 60 plus eight gives 68 units.
Compare that number with a calculator configured in tablets. Do not convert a medicine strength printed in milligrams into a tablet count; strength and the number of units describe different things.
Read a fractional result carefully
For an arithmetic example, 25 tablets divided by an entered consumption of two tablets a day gives 12.5 days. That means 12 complete daily quantities with one tablet remaining. It does not promise that every planned dose on the thirteenth day is covered.
This is a stock example, not an instruction to take two tablets daily. Use the schedule already confirmed for the medicine. A remaining fraction of a day is not permission to split a tablet or alter a dose.
Check what the record includes
Look for a refill added twice, an unopened pack omitted from the count, or a stock adjustment recorded on the wrong profile. Compare the starting balance and the dates of additions. If someone else keeps a second record, ask which entries were actually completed.
Keep a short explanation for a correction, such as “recounted unopened pack”. Do not rewrite dose history to force its total to match the stock.
Treat the result as a planning aid
Variable schedules and medicines used only when needed may not fit a fixed daily average. Likewise, a stock calculation does not assess expiry dates or storage conditions. Mark the estimate’s assumptions so a later reader knows its limits.
Use Doserra’s refill calculator to check the arithmetic, then keep the physical count and the forecast distinguishable. If the discrepancy raises a question about actual medicine use, take the record to a pharmacist rather than infer a dose from it.
