forecasting

[Patrick the K]

Hi - I am sure this is an easy one! I am trying to chart forecasted sales based on sales in the fiscal year thus far. I need help with a formula on my "Forecast" line that will pick up the YTD percentage of budgeted sales that the actual sales from previous months represent, then return that same percentage of the forecasted sales for the balance of the months. So, if YTD through the fourth month sales are trending at 85% of the forecast, the worksheet should re-project the remaining months at 85%. If the fifth month is above forecast, so the result is that the YTD totals are now 90% of forecast, the remaining months would want to now pick that up. Thanks!
