Kitchen Concentrate Dilution Calculator

Enter stock and target percentages on the same basis, plus the desired final amount. The calculator preserves the amount of concentrate solids in an ideal two-part dilution.

Stock concentrate 250 same unit as entered
Water to add 750 same unit as entered
Final amount 1000 same unit as entered

Boundary: This is an ideal two-component dilution calculation. It does not verify ingredients, compatibility, density or process suitability.

Formula

stock amount = target concentration × final amount ÷ stock concentration; water = final amount − stock amount

This is an ideal two-component dilution calculation. It does not verify ingredients, compatibility, density or process suitability.

How to use this calculator

  1. Use stock and target percentages expressed on the same basis.
  2. The target concentration cannot exceed the stock concentration when only water is added.
  3. Keep the final amount and output amounts in one consistent unit.

Worked example

To make 1,000 units at 20% from an 80% concentrate, combine 250 units concentrate with 750 units water.
