Enter the number of healthy seedlings and the number of seeds into the Germination Rate Calculator. The calculator will evaluate the Germination Rate. 

Germination Rate Formula

The following two example problems outline the steps and information needed to calculate the Germination Rate.

GERM = HS / #S * 100

  • Where GERM is the Germination Rate (%)
  • HS is the number of healthy seedlings 
  • #S is the number of seeds 

How to Calculate Germination Rate?

The following example problems outline how to calculate Germination Rate.

Example Problem #1:

  1. First, determine the number of healthy seedlings. 
    • The number of healthy seedlings is given as: 40.
  2. Next, determine the number of seeds. 
    • The number of seeds is provided as: 100.
  3. Finally, calculate the Germination Rate using the equation above: 

GERM = HS / #S * 100

The values provided above are inserted into the equation below and computed.

GERM = 40 / 100 * 100 = 40.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

number of healthy seedlings = 20

number of seeds = 200

Test your knowledge using the equation and check your answer with the calculator..

GERM = HS / #S * 100 = ?
