# Converting Months to Years and Months in Excel

Investment bankers juggle complex financial instruments with varying maturities and timelines in finance, making time a valuable resource. Precise time tracking is not just necessary; it’s a critical skill that can make or break deals.

So, we’ll dive into a crucial financial modeling and analysis aspect: converting months to years and months in Excel. Enhance your ability to manage fund maturities and communicate investment durations effectively by converting total months into a more readable format.

## Understanding Conversions in Excel

It’s just simple math to convert months into years and months. To do so, let’s split the number into full years and leftover months. Say an investment matures in 30 months or two years and six months. In math, we divide the total number of months by 12 to find full years. Then, we find leftover months using the modulus (what’s left after dividing). This basic idea will help us do the conversion in Excel.

## Step-by-Step Guide to Conversion

Below are two different ways to convert months to years and months in Excel:

### Method 1: Basic Arithmetic in Excel

Excel provides a variety of pre-built functions that simplify arithmetic calculations. For our purpose, we’ll focus on two essential operations: division and modulus. To determine the number of complete years, we’ll use the `INT` function, which returns the integer part of a number. The formula for years is:

`=INT(Months/12)`

Next, we’ll employ the `MOD` function to calculate the remaining months, which returns the remainder after division. The formula for the remaining months is:

`=MOD(Months, 12)`

### Method 2: Creating an Excel Formula

While the above formulas work perfectly fine, they separately output the years and months. Financial reporting makes it more convenient to have a single cell that displays the result in a readable format, such as “X years, Y months.” To achieve this, we can combine the previous calculations into one Excel formula:

`=INT(B2/12) & ” Years, ” & MOD(B2,12) & ” Months”`

Here, `B2` represents the cell containing the total months. The ampersand (`&`) is used for concatenation, allowing us to join the text and numerical results into a single string.

## Applying the Conversion to Investment Data

### Data Setup

With our conversion formula ready, let’s see how it can be applied to a typical investment banking scenario. Consider the following dataset as a sample of various investment funds with different maturity periods:

The above table represents a simplified version of investment bankers’ portfolios, focusing on the months until each fund matures.

### Using the Formula

To convert the ‘Months Until Maturity’ column into a more interpretable ‘Years and Months’ format, we’ll apply our combined formula from the step-by-step guide above:

1. In a new column adjacent to ‘Months Until Maturity’, enter the heading ‘Maturity in Years and Months’.

2. In the first cell under the new heading, type in the formula `=INT(B2/12) & ” Years, ” & MOD(B2,12) & ” Months”`, where `B2` is the cell containing the months for the first fund.

3. Press Enter, and Excel will display the result in the desired format, e.g., ‘1 Year, 6 Months’ for the Global Equity Fund.

4. To apply the formula to the remaining funds in the dataset, drag it down.

After applying the formula, your table should look like the one below:

With the formatted data, portfolio reviews and client reports become much more intuitive and accessible.

## Advanced Excel Tips for Financial Reporting

### Handling Special Cases

In finance, only a few things always go according to plan. There may be instances where you encounter zero or negative values in your dataset, mainly when dealing with adjustments or forecasting scenarios. To ensure your formulas can handle such exceptional cases, it’s essential to modify them accordingly.

For example, if a fund has 0 months until maturity, our current formula would display “0 Years, 0 Months.” While technically correct, showing “Matured” or “N/A” in such cases may be more appropriate. To achieve this, we can use Excel’s `IF` function to create a conditional statement:

`=IF(B9=0,”Matured”,INT(B9/12) & ” Years, ” & MOD(B9,12) & ” Months”)`

The above formula checks if the value in `B9` is 0, and if so, it displays ‘Matured’. Otherwise, it proceeds with the original conversion formula.

Similarly, you may want to display ‘Invalid’ or ‘Check Input’ for negative values to alert users of potential errors in the dataset. The `IF` function can be nested to handle multiple conditions:

`=IF(B10<0,”Invalid”,IF(B10=0,”Matured”,INT(B10/12) & ” Years, ” & MOD(B10,12) & ” Months”))`

By incorporating the above error-handling techniques, you can enhance the robustness and reliability of your financial models.

### Dynamic Arrays for Efficient Calculations

If you’re using Excel for Office 365, you’re able to access a powerful feature called dynamic arrays. With dynamic arrays, formulas can automatically spill results across multiple cells, eliminating the need for manual dragging or copying. It can significantly streamline the application of formulas across extensive financial datasets.

To use dynamic arrays with our conversion formula, enter the formula in the first cell of the output range and press Enter. Excel will automatically populate the results for the entire dataset. For example:

Dynamic arrays make it easier to work with large datasets and ensure consistency in calculations.

## Common Errors and Troubleshooting

Despite the straightforward nature of converting months to years and months in Excel, there are a few common pitfalls to watch out for:

1. Formatting issues: Ensure the cells containing your formulas are appropriately formatted. If the cell is formatted as ‘General’ or ‘Number’, the formula may display a numerical result instead of the desired text format. To fix the error, change the cell format to ‘Text’ or apply a custom number format.
2. Incorrect cell references: Double-check that your formulas reference the correct cells. A mistyped cell reference can lead to incorrect results or #REF! errors.
3. Division by zero: If a cell in your ‘Months Until Maturity’ column contains 0, the modulus operation (`MOD`) will result in a #DIV/0! error. Use the error-handling techniques previously discussed to mitigate the issue.
4. Overlooking exceptional cases: Consider special cases like negative values or huge numbers. Test your formulas with diverse inputs to ensure they handle such cases appropriately.

Check your formulas for typos or missing parentheses if you come across any errors or unexpected results. If the issue persists, try breaking down the formula into smaller parts and testing each component separately to isolate the problem.

## Conclusion

Converting months to years and months is a fundamental skill for investment bankers. It empowers them to effectively manage fund maturities and communicate investment durations to clients and stakeholders. With Excel’s versatile functions and the ability to tailor custom formulas, you can refine this conversion process to enhance the precision of your financial reporting.
