Tablet Mix Calculator

How to Use the Tablet Mix Calculator

  • Enter active ingredient(s) (mg per tablet) and tablet weight.

  • Choose whether to calculate by number of tablets or total active weight.

  • The calculator applies:

    Excipient weight = (Tablet weight – Σ Active ingredients) × Tablet count

  • Results show the exact excipient amount needed to reach your target mix.

  • Example: For a 500 mg tablet with 200 mg active, the calculator will output 300 mg excipient per tablet.

Next Step: Learn more about choosing the right excipients for your mix in our formulation guide.
