An autoregressive (AR) model forecasts future behavior based on past behavior data. This type of analysis is used when there is a correlation between the time series values and their preceding and succeeding values. Autoregressive modeling uses only past data to predict future behavior.
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)
To forecast accounts receivable, divide DSO by 365 for a daily collection rate. Multiply this rate by your sales forecast to estimate future accounts receivable. This method helps predict the amount you can expect to receive over a specific period.
The accounts receivable turnover ratio is a simple metric used to measure a business's effectiveness at collecting debt and extending credit. It is calculated by dividing net credit sales by average accounts receivable. The higher the ratio, the better the business manages customer credit.
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.

At its most basic, to make an expense forecast you can simply take last year's costs, add a percentage increase (say, 4%) to that number, and you're done. There's a bit more to it than that, though historical projections are a part of it.
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.
On the Data tab, in the Forecast group, select Forecast Sheet. In the Create Forecast Worksheet box, pick either a line chart or a column chart for the visual representation of the forecast. In the Forecast End box, pick an end date, and then select Create.
