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.
=FORECAST(x, known_y's, known_x's) The FORECAST function uses the following arguments: X (required argument) – This is a numeric x-value for which we want to forecast a new y-value. Known_y's (required argument) – The dependent array or range of data.
In Excel, the projected expenses after a 3.5% increase can be calculated using the formula '=B31(1+3.5%)', which adjusts the current expenses in cell B31 by the percentage increase. The formula multiplies the current expenses by 1 plus the percentage increase (expressed as a decimal).
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)
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.
Your step-by-step guide to creating an expense tracker in Excel Step 1: Create a new Excel workbook. Step 2: Set up columns. Step 3: Input initial data: expense categories, monthly budget, and actuals. Step 4: Add formulas to get a summary and totals.
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.

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.
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.
