How to Use Coronavirus Mask Calculator
The Coronavirus Mask Calculator helps families and small offices keep stock without overbuying.
- Pick a scenario — Solo, family, office or travel.
- People and days — Cover the planning period (a week, a month).
- Masks per person per day — One for commuting, more for medical or travel days.
- Safety buffer — Default 15%.
- Masks per box — Typically 50.
- Read masks needed and boxes to buy.
Formula & Theory — Coronavirus Mask Calculator
baseUse = people × days × perPersonPerDay
bufferAmount = baseUse × (bufferPct / 100)
totalNeed = baseUse + bufferAmount
boxesToBuy = ceil(totalNeed / masksPerBox)| Symbol | Meaning |
|---|---|
| people | People to cover |
| days | Planning period in days |
| perPersonPerDay | Average masks per person per day |
| bufferPct | Safety buffer percent |
| masksPerBox | Quantity per packaged box |
The Coronavirus Mask Calculator uses ceiling rounding so a 51-mask need still gives you two boxes, never one short.
