Dear Rehan,
You have not mentioned clearly why you have raised this query. Are you student or professional? Would you like to start your own business? If yes, what type of business it is?
The average business plan has following components:
Part I: Foreword
Part II: - The Executive Summary
Part III: - Introduction to the Business
Part IV: - The Product
Part V: - The Market
Part VI: - Costing, Pricing and Sales Forecast
Part VII: - The Marketing Plan
Part VIII: - The Manufacturing Plan (Trading Plan if the product is not manufactured)
Part IX: - Organisation and Staffing
Part X: - Financial Forecasts - Revenues, Cost and Profitability
The above business plan is for us and not for getting some loan from the bankers. For them the format of business plan is different.
Secondly, you need to read thoroughly famous book on marketing by Philip Kotler. You may not buy a new one even a second hand copy will do. Referring the book apart, before raising this query you could have searched this forum. Anyway click the following links to read my replies of past posts:

Strategic Marketing Plan
Of the three, the first two replies might not be directly related to your business. However, these will be immencely useful. The third link is on how to make strategic marketing plan. This link will help you even if you do not read any book on marketing. Yet I strongly recommend reading the Kotler's book mentioned above as it will develop robust business framework in your mind.
All the best!
