Tests Per Million Formula

TPM = T / P * 1000000

Variables:

• TPM is the Tests Per Million (tests/million people)
• T is the number of tests
• P is the available population

To calculate Tests Per Million, divide the number of tests by the available population then multiply by 1,000,000.

How to Calculate Tests Per Million?

The following steps outline how to calculate the Tests Per Million.

1. First, determine the number of tests. 
2. Next, determine the available population. 
3. Next, gather the formula from above = TPM = T / P * 1000000.
4. Finally, calculate the Tests Per Million.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :
