How to Calculate Yield

Whether you are an economist, chemist, or mechanical engineer, the concept of yield provides a convenient way to measure payoff.


  • Step 1: Find the yield strength of a material by measuring the mechanical stress at which the material ceases to return to its original shape when the stress is removed. Now you should have a good grasp on yield.
  • FACT: The Yield sign was added to the U.S. Manual on Uniform Traffic Control Devices in 1954.
  • TIP: Percent yield is the actual yield of product achieved in the reaction divided by the theoretical yield, with the quotient multiplied by 100 percent.
  • Step 2: Calculate the theoretical yield of a chemical reaction by determining the amount of product that would be formed if the reaction were allowed to go to completion.
  • Step 3: Calculate current yield in an investment by dividing the annual interest in dollars by the price and multiplying by 100 percent. For example, if you buy a bond that pays $1,000 each year and you pay $10,000 for it, the current yield is 10 percent.
  • TIP: A 10 percent yield means the investment averages 10 percent return each year.
  • Step 4: Know that in a general sense, the meaning of yield is to produce a return from some kind of expenditure.
