0014 <title>What is a Forecast?</title>
0015 
0016 <para>
0017   In &kmymoney;, a Forecast is a prediction of the balances of Accounts during a
0018   specified future period of time.</para>
0019 
0020 <para>
0021   Forecasts can be predicted using one of two methods.

0041 
0042 <para>

0044   in the Forecast pane.
0045 </para>
0046 
0047 <para>
0048   &kmymoney; Forecast provides a summary, showing the predicted balances at
0049   account cycle dates and the expected difference between the starting and
0050   ending balances.  The length of the account cycle can be set by the user.  The
0051   summary also displays messages about significant predicted changes to the
0052   accounts during the forecast period.
0053 </para>
0054 
0055 <para>
0056   As well as the summary, &kmymoney; Forecast also allows you to view day-by-day
0057   balances and view the minimum and maximum balances for each forecast account
0058   cycle.
0059 </para>
0060 
0061 <para>
0062   By default the Forecast is created for 90-days, with 30-day account cycles
0063   using Scheduled and Future Transactions.

0076   The Forecast window is split into five tabs:

0078 
0079 <sect2>
0080 <title>Summary Tab</title>
0081 
0082 <para>

0118 
0119       <para>The first account cycle date is the first Forecast date.  By default
0120         this is the current date plus one account cycle, but can change
0121         depending on the "Day of Month to start Forecast" setting.</para>
0122 
0123       <para>Remaining account cycle dates are determined by adding the account
0124         cycle length to the previous account cycle date.  This is continued
0125         until the calculated account cycle date would be beyond the Forecast
0126         period.</para>
