Choose one measurement family
If remaining product is measured in grams, the daily assumption must also be grams. Use mL with mL. We do not infer density, a standard fingertip amount or a universal volume per pump.
Leave the usage assumption blank until you supply it
The tool deliberately has no recommended daily amount. A forecast does not account for individual skin needs, treatment directions, sharing, spillage or unmeasured residue in a container.
Treat lead time as an assumption
Enter a delivery period you want to explore. The result shows an arithmetic gap under those inputs, not live retailer inventory or a delivery promise. Recheck the offer before ordering.
Before you decide
- Use matching units
- Enter your own assumption
- Recheck actual stock and delivery
