How long will it take to write a business plan?

Time it takes to write a business planThe time it takes to research and write a business plan is contingent upon a number of factors including the concept, the intended audience, status of business (start-up or existing) and number of people on the planning team. If you're flying solo and it's an entirely new concept, it will take considerably longer than if it was an existing business with three or four team people tackling the plan. On average, a start-up plan will take anywhere from 160 to 640 hours to research and write. Established businesses should allow between 40 and 160 hours.
