Moisture Loss Calculator

Calculate moisture loss from the weight before and after drying, curing or dehydrating.

Usage Tip

Track weight to a target loss rather than guessing by time alone.

Moisture Loss
— % loss
Weight lost as percent
THE MATH
loss % = (start − end) ÷ start × 100
The difference between start and end weight is water (and some fat) lost.
Useful for jerky, dried fruit and curing where target moisture loss matters.
