Financial accounting reports are prepared 
    for the use of external parties such as shareholders and creditors, whereas 
    managerial accounting reports are prepared for managers inside the 
    organization. 
          
This contrast in basic orientation results 
    in a number of major differences between financial and managerial 
    accounting, even though both financial and managerial accounting often rely 
    on the same underlying financial data. In addition to the to the differences 
    in who the reports are prepared for, financial and managerial accounting 
    also differ in their emphasis between the past and the future, in the type 
    of data provided to users, and in several other ways. These differences are 
    discussed in the following paragraphs.
    Emphasis on the Future:
    Since planning is such an important part of the manager's job, managerial 
    accounting has a strong future orientation. In contrast, financial 
    accounting primarily provides summaries of past financial transactions. 
    These summaries may be useful in planning, but only to a point. The future 
    is not simply a reflection of what has happened in the past. Changes are 
    constantly taking place in economic conditions, and so on. All of these 
    changes demand that the manager's planning be based in large part on 
    estimates of what will happen rather than on summaries of what has already 
    happened.
    Relevance of Data:
Financial accounting data are expected to be objective and verifiable. 
    However, for internal use the manager wants information that is relevant 
    even if it is not completely objective or verifiable. By relevant, we mean 
    appropriate for the problem at hand. For example, it is difficult to verify 
    estimated sales volumes for a proposed new store at good Vibrations, Inc., 
    but this is exactly the type of information that is most useful to managers 
    in their decision making. The managerial accounting information system 
    should be flexible enough to provide whatever data are relevant for a 
    particular decision.
    Less Emphasis on Precision:
    Timeliness is often more important than precision to managers. If a 
    decision must be made, a manager would rather have a good estimate now than 
    wait a week for a more precise  answer. A decision involving tens of 
    millions of dollars does not have to be based on estimates that are precise 
    down to the penny, or even to the dollar. In fact, one authoritative source 
    recommends that, "as a general rule, no one needs more than three 
    significant digits., this means, for example, that if a company's sales are 
    in the hundreds of millions of dollars, than nothing on an income statement 
    needs to be more accurate than the nearest million dollars. Estimates that 
    accurate to the nearest million dollars may be precise enough to make a good 
    decision. Since precision is costly in terms of both time and resources, 
    managerial accounting places less emphasis on precision than does financial 
    accounting. In addition, managerial accounting places considerable weight on 
    non monitory data, for example, information about customer satisfaction is 
    tremendous importance even though it would be difficult to express such data 
    in monitory form.
Segments of an Organization:
Financial accounting is primarily concerned with reporting for the 
    company as a whole. By contrast, managerial accounting forces much more on 
    the parts, or segments, of a company. These segments may be product lines, 
    sales territories divisions, departments, or any other categorizations of 
    the company's activities that management finds useful. Financial accounting 
    does require breakdowns of revenues and cost by major segments in external 
    reports, but this is secondary emphasis. In managerial accounting segment 
    reporting is the primary emphasis.
Generally Accepted Accounting Principles (GAAP):
Financial accounting statements prepared for external users must be 
    prepared in accordance with 
    generally accepted accounting principles (GAAP). 
    External users must have some assurance that the reports have been prepared 
    in accordance with some common set of ground rules. These common ground 
    rules enhance comparability and help reduce fraud and misrepresentations, 
    but they do not necessarily lead to the type of reports that would be most 
    useful in internal decision making. For example, 
    GAAP requires that land be 
    stated at its historical cost on financial reports. However if, management 
    is considering moving a store to a new location and then selling the land 
    the store currently sits on, management would like to know the current 
    market value of the land, a vital piece of information that is ignored under
    generally accepted accounting principles (GAAP).
Managerial Accounting is Not Mandatory:
Financial accounting is mandatory; that is, it must be done. Various out 
    side parties such as Securities and exchange commission (SEC) and the tax 
    authorities require periodic financial statements. Managerial accounting, on 
    the other hand, is not mandatory. A company is completely free to do as much 
    or as little as it wishes . No regularity bodies or other outside agencies 
    specify what is to be done, for that matter, weather anything is to be done 
    at all. Since managerial accounting is completely optional, the important 
    question is always, "Is the information useful?" rather than, "Is the 
    information required?"
