Key Takeaway:
- The BINOM.INV formula in Excel enables users to calculate the probability of a certain number of successful outcomes in a given number of trials, using the binomial distribution. This formula is particularly useful in fields such as statistics and finance for making predictions and analyzing data.
- BINOM.INV works by calculating the probability of getting a specified number of successful outcomes in a given number of trials, with a certain probability of success. This formula takes three arguments: the number of trials, the probability of success, and the number of successful outcomes desired.
- Examples of using the BINOM.INV formula include predicting the likelihood of a certain number of customers making a purchase out of a total number of visitors to a website, or the probability of a certain number of patients responding to a particular treatment out of a group of patients with a specific disease.

What is BINOM.INV formula in Excel?
Comprehend the BINOM.INV formula in Excel? The answer is to understand its definition and mechanics. Check out the sub-sections ‘Definition of BINOM.INV’ and ‘How does BINOM.INV work?’ Gaining a good grasp of this formula is simple.
Definition of BINOM.INV
The Excel Formula BINOM.INV is used to calculate the Inverse of the Cumulative Distribution Function (CDF) for a Binomial distribution. It returns the minimum number of successes in a given number of trials with a specified probability distribution.
To use this formula, we need to provide three inputs – the probability of success (p), the total number of trials (n), and the cumulative probability level (alpha). The output is the smallest integer value that results in a cumulative_probability equal to or greater than alpha.
One unique detail about BINOM.INV is that it assumes that each trial is independent and has only two possible outcomes – either success or failure. It is widely used in fields such as finance, quality control, and inventory management.
A true history about BINOM.INV Formula is that it was first introduced in Microsoft Excel 2010 version as part of its Statistical functions category. Since then, it has gained popularity among users globally due to its accuracy and ease of use.
BINOM.INV: Where Excel gets to play God with probabilities.
How does BINOM.INV work?
BINOM.INV is an Excel formula used to estimate the probability of a set number of successes in a fixed number of trials. It is used in statistical analysis, particularly in binary experiments such as estimating the likelihood of heads or tails with flipping coins, or success or failure with conducting surveys.
- 1. you need to choose the value of “N” which represents the total number of trials.
- Then, decide on the probability represented by “p” for achieving success in each attempt.
- You also need to choose “k”, which stands for the target number of successes that you aim to achieve.
- Type the formula
=BINOM.INV(N,p,k,FALSE), and press enter in any cell within an Excel sheet.
It is important to note that this function can only be used for discrete variables following a binomial distribution. The parameter FALSE signifies cumulative binomial probability (which sums up probabilities) would not be calculated.
The results returned by BINOM.INV will show how many successful outcomes are necessary to meet a specific level of confidence, given the parameters specified. For instance, using this function can determine how many more votes needed before winning an election.
A verified fact about BINOM.INV is that it originates from “binomial inverse distribution” and was introduced as an Excel worksheet function since version 2010.

Syntax of BINOM.INV Formula
Grasping the syntax of BINOM.INV formula and using it with ease needs knowing about the arguments it takes.
This helps differentiate successes and probabilities of success. Moreover, this section assists in using the formula more effectively, and avoiding typical mistakes.
Examples of BINOM.INV formula use are also provided in this section.
Arguments of BINOM.INV formula
The BINOM.INV formula comprises several arguments that determine the results of a binomial distribution in Excel. These arguments help calculate the probability of outcomes based on fixed trials and constant probability.
Using tabular format, we illustrate the different arguments involved in BINOM.INV formula. The table has two columns – ‘Argument’ and ‘Function’.
| Argument | Function |
|---|---|
| Data Series (Number) Ranging from 0 to value close to 1 | Determines the probability of success in each trial |
| Number of Trials | Number of times that the test is to be conducted |
| Probability of Success | The probability that a given event will occur in each trial |
| Cumulative | Logical value (TRUE/FALSE) to determine the type of distribution to return |
Notably, one unique detail is that users must ensure values for arguments are entered accordingly for accurate results.
Pro Tip: Setting incorrect input values will result in inaccurate outputs, making reviewing your BINOM.INV calculated results essential to ensure accuracy. Get your probability game on point with these examples using the elusive BINOM.INV formula.
Examples of using BINOM.INV formula
To explore the practical applications of BINOM.INV formula, here’s a step-by-step guide that can help you to understand its usage:
- Start by analyzing the data set and collecting all relevant information about it.
- Open your Excel sheet, click on the cell where you want to apply the formula and type ‘
=BINOM.INV‘ - In the parentheses of this formula, enter different arguments such as ‘number_f‘ (number of favorable outcomes), ‘trials‘ (total number of trials) and ‘probability_s‘ (probability of success in each trial)
- Close parentheses and press ctrl+shift+enter to execute this formula.
- The output of BINOM.INV will show you the smallest value for which the cumulative binomial distribution is greater than or equal to your selected alpha value.
Remember that BINOM.INV has a few limitations in terms of its scope and application. For example, it requires discrete binomial data that is based on a fixed number of possible outcomes. Additionally, it only provides one type of output- discrete probability.
To get the best results when using BINOM.INV Formula, here are some suggestions:
- At times, the number returned by BINOM.INV formulates an important threshold value for making business decisions
- It’s ideal to double-check inputs carefully before opting for any resulting values
BINOM.INV: the formula that calculates your chances of success, but also accurately predicts the probability of failure.
