Salt Percentage Calculator

Calculate salt by percentage of food weight for curing, fermenting or seasoning.

Usage Tip

Weigh salt rather than measuring by spoon, as salt crystals vary in density.

Salt Needed

By weight percent
THE MATH

Percentage salting (by total weight) gives consistent results across batch sizes.
Use non-iodised salt for fermenting; iodine and anti-caking agents can cause issues.
