What Is BINOM.INV and How Is It Used?
BINOM.INV is an Excel formula that calculates the likelihood of a certain number of successes out of a total number of attempts. It can be used to determine the probability of two outcomes, such as success or failure, yes or no, or true or false. This formula is popular in fields like finance, engineering, and science.
It takes three variables: a probability (p), the number of trials (n), and x – the specified number of successful outcomes. BINOM.INV then returns the probability of x successes in n trials with probability p for each trial.
This formula can be used to make decisions about investments and projects. For example, it can tell you the odds of profiting from stocks, using your strategy and market trends. It was introduced to Excel 2010 as part of an update to the statistical functions. Before this update, users had to build complex formulas to make binomial calculations.

Examples of BINOM.INV: Practical Applications
Excel’s BINOM.INV function is a powerful tool for calculating probabilities and making predictions. Let’s explore its practical applications. We’ll learn how to use BINOM.INV to calculate the probability of success and determine the number of trials needed for a certain level of confidence. These applications of BINOM.INV can help us make informed decisions backed by data. Let’s get started!
Example 1: Finding the Probability of a Success
To work out the chance of success, we can use the BINOM.INV Excel formula. Let’s look at an example:
Say there are 10 individuals taking a test and only one will be chosen. What is the likelihood of you being picked?
We know that there are 10 people and only one will be chosen – which means the probability of being chosen is 1/10 or 0.1.
Using the BINOM.INV formula, we can calculate the likelihood of getting exactly one success out of 10 trials with a success rate of 0.1. We can see this in the table below:
| Number of Trials | Probability |
| 1 | =BINOM.INV(1,10,0.1,FALSE) |
| 2 | =BINOM.INV(2,10,0.1,FALSE) |
| 3 | =BINOM.INV(3,10,0.1,FALSE) |
| 4 | =BINOM.INV(4,10,0.1,FALSE) |
| 5 | =BINOM.INV(5 ,10 ,0.1 ,FALSE ) |
As we can see in the table, when we enter ‘=BINOM.INV(1,10,0.1,FALSE)‘ in the second column to calculate the chances of getting one success out of 10 trials with a success rate of 0.1, we get a result of 0.387420489 which means your chance is around 39% of being picked.
Trivia: The BINOM.INV formula can be used in manufacturing to figure out the probability of how many defective items will be produced from a batch.
Example 2: Finding the Number of Trials Needed
Example 2: Finding the Number of Trials Needed
BINOM.INV can help us determine the number of trials needed. Let’s say we have a survey on customer satisfaction and we need 95% confidence level, with a 5% max error margin. How many people should we sample? Plug in the values: =BINOM.INV(0.95, A4, A5). A4 is the number of trials (unknown) and A5 is the probability of success (.5). Subtract 0.05 (probability of failure) and the answer is 83. So, survey at least 83 customers for desired accuracy.
Using BINOM.INV to calculate sample size has many advantages. It provides precise results, saving time and reducing guesswork. Plus, it strengthens logical thinking and data-backed insights. It can be used for businesses of all sizes.

|---|---|---|---|
| BINOM.INV | ✓ | X | X |
It shows that BINOM.INV works only with binomial distributions, not with Poisson or Bernoulli. We must understand when and where to correctly use BINOM.INV. Incorrect use in other contexts will lead to wrong answers. Therefore, we need to be aware of the scope of its application.
When using it, keep in mind that it should be used with a fixed number of trials, each having two possible outcomes, and statistically independent from one another. Chaitanya Sagar, a software developer, explains the importance of understanding when and where to use the formula within its appropriate scope. He also shows that using the BINOM.INV formula on non-binary data leads to incorrect results.
Not Suitable for Large Datasets: When to Consider Other Options
Using BINOM.INV for large datasets is not always the best option. To decide if it is suitable, consider a table. It shows factors that influence if BINOM.INV works. The relevant range is small datasets, low to medium probability level, and few successes. If the dataset is outside these ranges, try other methods such as Monte Carlo simulation or numerical methods.
Still, BINOM.INV is useful for small datasets with simple probabilities and low computational time. In any case, consulting experts in statistics or data science is recommended.
