Enter the usable film produced and raw material used into the calculator to determine the film yield. This calculator can also evaluate any of the variables given the others are known.

Film Yield Formula

The following formula is used to calculate the film yield.

FY = (UF / RM) * 100


  • FY is the film yield (%)
  • UF is the usable film produced (units)
  • RM is the raw material used (units)

To calculate the film yield, divide the amount of usable film produced by the amount of raw material used. Multiply the result by 100 to convert the ratio to a percentage. This percentage represents the efficiency of the film production process, with a higher percentage indicating a more efficient and cost-effective process.

What is a Film Yield?

Film yield refers to the amount of usable film produced from a given amount of raw material. It is a measure of efficiency in the film production process, taking into account factors such as waste, defects, and quality control. A higher film yield indicates a more efficient and cost-effective production process. This term is commonly used in industries such as semiconductor manufacturing, where thin films of material are used in the production of electronic devices.

How to Calculate Film Yield?

The following steps outline how to calculate the Film Yield.

  1. First, determine the usable film produced (UF) in units.
  2. Next, determine the raw material used (RM) in units.
  3. Next, use the formula FY = (UF / RM) * 100 to calculate the Film Yield.
  4. Finally, calculate the Film Yield.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
