Supply / Run-Out Calculator
Estimate how long your current supply will last using the amount you already have, your own amount per administration and your own frequency. This calculator performs arithmetic only and does not recommend an amount or schedule.

How the supply calculator works
Enter the amount in each vial or container, how many you currently have, and the amount and frequency you already plan to use. The calculator estimates how many full administrations are available and how long that supply would last.
How are mg and mcg handled?
Milligrams and micrograms are converted automatically using 1 mg = 1,000 mcg. IU is kept separate because there is no universal conversion from IU to mg or mcg.
Why might the run-out date differ from a real calendar?
Daily, every-other-day, weekly and every-X-days schedules can be projected directly. “X times per week” is treated as an average spacing across seven days, so exact weekday scheduling may differ slightly.
