# How To Use TINV() Function in Google Sheets

Description

See T.INV.2T

Common questions about the TINV formula:

1. What is the TINV formula?
2. How is the TINV formula different than the other formulas available in Google Sheets?

How can the TINV formula be used appropriately:

1. The TINV formula can be used to calculate time intervals in two different ways: as the difference between two Date and Time values, or as the amount of time elapsed from a certain Date and Time value.
2. TINV should be used to calculate the difference between two Date and Time values, not average of two separate time intervals.

How can the TINV formula be commonly mistyped:

1. People may use the TINV formula to calculate the average of two different time intervals instead of the difference between the two time intervals.
2. People may also forget to type the second Date and Time value following the comma and use the formula incorrectly.

What are some common ways the TINV formula is used inappropriately:

1. Using the TINV formula with incorrect syntax, such as including a third value that is not a Date and Time value.
2. Trying to calculate an average of two different time intervals with the TINV formula, which it is not designed to do.

What are some common pitfalls when using the TINV formula:

1. Using incorrect syntax, such as forgetting to specify a second Date and Time value after the comma.
2. Trying to use the TINV formula to calculate the average of two different time intervals.

What are common mistakes when using the TINV Formula:

1. Not defining the second Date and Time value correctly—especially if it is a relative date instead of an absolute one.
2. Not using the correct syntax and forgetting to type a comma before the second value.

What are common misconceptions people might have with the TINV Formula:

1. Believing the TINV formula will calculate the average of two different time intervals instead of the difference between them.
2. Thinking the TINV formula will calculate the total duration of two separate time intervals instead of just the difference between them.
