Fiscal Year vs Calendar Year

Differences Between Fiscal Year and Calendar Year

There are two types of years that prevail in the corporate world. These two years are Fiscal year and Calendar year. The similarity between these years is that these last for a period of total 365 days or consecutive twelve months. Calendar year begins on the first of January and ends on 31st December every year while fiscal year can begin on any day of the year but will end on exactly the 365th day of that year. Both these years have a total period of consecutive twelve months.

What is Fiscal Year?

A fiscal year can be defined as a year in which business organizations/ firms/ companies/ entities prefer preparing their financial reports for the year. This year may not be the same in all the countries. In a fiscal year reporting method, companies may choose to prepare their financial statements on a different twelve-month basis and not the same as the calendar year.

It is 12 months used for calculating and preparing annual (“yearly”) financial statements in businesses and other organizations all over the world.

Let us look at Procter & Gamble (P&G) Financial Reporting.

P&G Fiscal Year

We note that P&G uses a different year ending for reporting its Financial Statements than that of Colgate. P&G usesfiscal year ending June 30.

What is Calendar Year?

A year is simply defined as the time taken by the earth to make one revolution around the sun.

Now, what is a Calendar Year? Generally speaking, it is a year that begins on the New Year’s Day of a given calendar system and ends on the day before the following New Year’s Day, and thus consists of a whole number of days. There are different calendar years like the Islamic Calendar, the Gregorian Calendar, etc. One which is most widely used in the Gregorian calendar. It begins on January 1 and ends on December 31, consisting of 365 days (366 days once every four years).

In a calendar year reporting method, companies will prepare their financial reports/ statements for the year based on the transactions that have taken place on the 1st of January and will incorporate all other transactions that have taken place until the 365 days of the year that is 31st December.

Colgate reports its financial statements for years ended December 31. This simply means that Colgate uses Calendar Year (1st January – 31st December).

Calendar vs. Fiscal Year Retailer Case Study

Let us take an example of a Retailing Business. Seasonality in retailing business is generally seen in December and January holiday months, where sales are usually higher than the other months.

Let us also assume that a retailer Coy R had bumper sales the months of Dec’15 and Jan’16. However, it underperformed in the months of Dec’16 and Jan’17.

Case 1 – If Coy R follows Calendar Year

If the management prepares its financial statements using the Calendar year, then will be two implications –

  1. High performing month of Dec’15 gets included with the 2015 year ending results
  2. However, one high performing month of Jan’16 and one underperforming month of Dec’16 is incorporated in 2016 results.

When we compare 2015 results with that of 2016, we note that the comparison is not fruitful at all, as the full effect of seasonality is not captured.

Retailer - Fiscal Year vs Calendar Year

Case 2 – If the retailer follows Fiscal year

If the retailer choose a fiscal year different from the calendar year (say 1st April to 31st March), then

  1. FY2016 (1st April 2015 to 31st March 2016) will include the high performing months (Dec’15 and Jan’16)
  2. FY2017 (1st April 2016 to 31st March 2017) will consist of the underperforming months (Dec’16 and Jan’17)

This time when we compare FY2016 with that of FY2017, we can effectively contrast an excellent season with that of a poor season, thereby effectively capturing the seasonality.


This is why the Fiscal year is beneficial.

    Hi dheeraj sir,
    I have a question that if one company is following calender year and other is following fiscal year.
    What we have to do for comparing financials of both companies?
    Your blog is one of the best blog. Thanks

    • Dheeraj Vaidya says

      Good question Aman. for comparing companies with a calendar year to that of a fiscal year, there is a process called “calendarization”. this means that you need to convert the financials of fiscal year company to that of calendar year. For eg. If a company follows March year end and you want to compare this with a company that follow calendar year – December end.
      Sales (FY2017) = Quarter ending March 2017 Sales + December 2016 Sales + September 2016 Sales + June 2016 Sales
      For calendarization, use this Sales (Calendar year 2016) = December 2016 Sales + September 2016 Sales + June 2016 Sales + Quarter ending March 2016 Sales
      Likewise, for other line items. I understand that this is a bit difficult and tedious as lots of corresponding data may not be available.
