#Accounting - What's a T account? Why use them?

Question

What's a T account? And why use them?

Answer

A T account is a simple but effective way to organize the activity in any given account.

Analysis

Let's first talk about accounts. An account is a way to gather similar activity in one place. For instance, over the course of a year, let's have Sample Co. have a number of sales throughout the year. We can sum up those sales to see the sales activity for the year. For an example, let's have Sample Co have sales of $100,000 for the year.

This $100,000 sales figure is made up of smaller sales throughout the year. We list them individually as they happen. A part of that list might look like this:

$500
$1000
$250
$300

and so on.

Some transactions will increase the balance of the account and some will decrease that balance. Take the account Cash for instance - as sales are made, cash comes into the company. As inventory is purchased, salaries are paid, and other outflows are accounted for, the balance of the account decreases.

One way to show this would be to list out all the transactions in a single list:

 $1,000
-$350
-$15
-$25
$300

and so on. Which can get messy.

Another way to look at the accounts is to put all the amounts that increase the account in one list and all the amounts that decrease the account in another list. To save space and to keep things organized, we can draw a T, put the account name above the crossbar of the T, and have amounts on one side of the T's vertical line increase the account and on the other side put those amounts that decrease it. It'll look something like this:


        Cash
------------------
$1000 |
           | $350
           | $15
           | $25
$300   |
