# Rolling Budget or Continues Budget

Rolling budget is the budgeting method in which the company keeps adding new period to the full accounting period. Accountants keep adding a new accounting period to replace the past one. For example, we prepare a budget for 2020 which start from January to December 2020, after the end of January 2020, we need to update our budget which reflects the last change. The updated budget will cover from February 2020 to January 2021. It will continue to update every month, the oldest month will be placed by the most recent month.

Some companies use a rolling budget every three months (quarterly) instead of a monthly basis. It will reduce the time spend on preparing new budget.

## Example

Company A prepares an annual rolling budget for the upcoming year. The budget cover from January to December 202X. The budget can summary and separate by month as following:

Month Revenue Expense Profit
January 200,000 140,000 60,000
February 300,000 210,000 90,000
March 250,000 175,000 75,000
April 100,000 70,000 30,000
May 400,000 280,000 120,000
June 280,000 196,000 84,000
July 320,000 224,000 96,000
August 350,000 245,000 105,000
September 190,000 133,000 57,000
October 750,000 525,000 225,000
November 150,000 105,000 45,000
December 800,000 560,000 240,000
Total 4,090,000 2,863,000 1,227,000

So what happens when the actual result of January 202X comes out?

During January 202X, company A makes sales \$ 210,000, expense 160,000 so the profit is only \$ 50,000. The budget for the next 12 months will change by deducting the January 202X and add another which is January 202X + 1. The rolling budget will look like this:

Month Revenue Expense Profit
February 300,000 210,000 90,000
March 250,000 175,000 75,000
April 100,000 70,000 30,000
May 400,000 280,000 120,000
June 280,000 196,000 84,000
July 320,000 224,000 96,000
August 350,000 245,000 105,000
September 190,000 133,000 57,000
October 750,000 525,000 225,000
November 150,000 105,000 45,000
December 800,000 560,000 240,000
January 202X + 1 220,000 160,000 60,000
Total 4,110,000 2,883,000 1,227,000

After the end of February 202X, we need to roll to the next month which is March and keep do the same for year around.
