# COUPDAYSNC Excel Formula

Microsoft Excel is one of the valuable tools for people who are working with accounting and finances. The program has so many functions that you need to learn in order to finish the tasks easily and accurately. Each function has distinct work on how a certain computation is done efficiently. One of the functions that you should learn in Excel is the COUPDAYSNC. The name of this function is an abbreviation for Coupon Settlement Next Coupon. It aids to compute the number of days between the security’s date of the coupon and the date of settlement. If you are using Microsoft Excel in organizing or storing your data, below are the tips on how you can accomplish it efficiently with the use of COUPDAYSNC function:

• Install the required add on – the function will not work automatically once you open a worksheet. You need to install first the Analysis ToolPak. From the menu bar, select “Tools” and wait for a couple of seconds for the drop down menu to appear. Once the menu appears, choose “Add-ins” and wait for the list to display. The list has selection for Analysis ToolPak. Once the list comes out, mark the box next to the Analysis ToolPak option.  After marking the box, the computer will automatically install it.
• Familiarize yourself with the numerous codes and COUPDAYSNC formula – there are different keywords and formula required in order for the function to be used effectively. Basically, the formula for COUPDAYSNC is “=COUPDAYSNC(settlement_date, maturity, frequency, [basis])”. The settlement_date is the date when the buyer purchased the coupon. Maturity is the date when the coupon will reach maturity. Frequency is the required number of payments per year this could be quarterly, semi-annually or annually. Basis is the number of years, months and days used in the computation. You need to make sure that you study the formula very well so that you can use the COUPDAYSNC function accurately.
• The basis must be understood well – before using the function, basis must be set first. If you don’t want to change the basis, then Excel will automatically use zero. With this, the computation will employ the method of United States in day count basis, which is 30 days in one month and 360 days every year. But, once you enter in 1, then Excel will utilize the actual day’s number in one month and years. Once you input 2, then 2 counts of actual days of a certain month is used but in accord with 360 year, while 3 employed 365 days in specified year. The value of 4 is just the same with 3 but uses the European method of counting days.
• Enter the codes and syntax carefully – this is done to make sure to get an accurate answer.

It is common to encounter error during the process of computation using COUPDAYSNC function. Once you encounter this, check the formula and the codes that were entered. Moreover, check also the characters and spelling used, they might be wrongly typed in. Ensure that everything is correct and in right order and you have entered valid amounts and dates. Most of the time, error appears due to incorrect input of data.
