The AR balance is based on the average number of days in which revenue will be received. Revenue in each period is multiplied by the turnover days and divided by the number of days in the period to arrive at the AR balance.
The pro forma accounts receivable (A/R) balance can be determined by rearranging the formula from earlier. The forecasted accounts receivable balance is equal to the days sales outstanding (DSO) assumption divided by 365 days, multiplied by 365 days.
Forecasting the AR(1) Time Series Model ˆβ1=∑i=1(xi−ˉx)(yi−ˉy)√∑ni=1(xi−ˉx)∑ni=1(yi−ˉy). In the AR(1) model we may set yt−1=zt,t=2,…,T, xt=zt,t=1,…,T−1 and n=T−1 and plug-in the above formula to obtain an efficient estimate of β1.
How to do sales forecasting in Excel: Step-by-step Create a new Excel worksheet. Open a new Excel spreadsheet and enter your historical data (sales over time). Create your forecast. Go to the Data tab and find the Forecast Sheet option. Adjust your sales forecast. View your ready sales forecast.
Here's a common formula for forecasting sales: Sales Forecast = (Last Month Revenue + Expected Growth – Expected Churn) DSO = (Accounts Receivable / Total Credit Sales) x Number of Days in the Period. Accounts Receivable Forecast = Days Sales Outstanding (DSO) x (Sales Forecast / Time)
By dividing DSO by 365 (the total number of days per year), you get a daily rate of how long it typically takes to collect a receivable. Multiplying this rate by your sales forecast gives you an estimated accounts receivable amount you can expect for that period.
You can find the AR aging percentage by dividing the total amount of receivables that are over 90 days past due by the total amount of receivables outstanding.
The pro forma accounts receivable (A/R) balance can be determined by rearranging the formula from earlier. The forecasted accounts receivable balance is equal to the days sales outstanding (DSO) assumption divided by 365 days, multiplied by 365 days.
The formula for net credit sales is = Sales on credit – Sales returns – Sales allowances. Average accounts receivable is the sum of starting and ending accounts receivable over a time period (such as monthly or quarterly), divided by 2.
Formula: Sales forecast = estimated amount of customers x average value of customer purchases.
