Simple Monthly Sales Forecasting Excel Template

Sales Forecasting, Monthly Planner, and Simple are the three core principles that define this Excel template. Designed for small to medium-sized businesses, individual sales professionals, or team leaders who need a streamlined way to predict and track monthly sales performance, this template provides an intuitive interface without unnecessary complexity.

School Sheet Names

The template consists of four main sheets:

1. Forecast Overview: The central dashboard summarizing key metrics and visualizations.

3. Historical Performance: A reference sheet with past actual sales to compare against forecasts.
4. Instructions & Tips: A guide that explains how to use the template effectively.

Table Structures and Columns in Monthly Sales Data Sheet

The Monthly Sales Data sheet is structured as a clean, easy-to-use table with the following columns:

Formulas Required

All calculations are automatically computed using built-in Excel formulas to ensure accuracy and reduce manual errors:

• Forecasted Revenue ($): =IF(AND([@[Forecasted Units Sold]] <> "", [@[Average Unit Price ($)] <> ""), [@[Forecasted Units Sold]] * [@[Average Unit Price ($)]], 0) This ensures a zero is returned if either input is missing.
• Monthly Total Revenue (in Forecast Overview): On the Forecast Overview sheet, use: =SUMIFS('Monthly Sales Data'!E:E, 'Monthly Sales Data'!A:A, "Jan 2024") This sums all forecasted revenue for a given month.
• Year-to-Date (YTD) Total: Use =SUMIFS('Monthly Sales Data'!E:E, 'Monthly Sales Data'!A:A, "<=" & DATE(2024,12,31)) to calculate cumulative forecasted revenue across all months in the year.
• Forecast Accuracy (in Historical Performance): Compare actual vs. forecast using: =IF([@[Actual Revenue]] <> 0, (1 - ABS([@[Forecast Revenue]] - @[Actual Revenue]) / @[Actual Revenue]), 0) This calculates the percentage accuracy.

Conditional Formatting

To enhance readability and identify key performance indicators, the template includes several conditional formatting rules:

• Highlight Over-forecasted Rows: If Forecasted Revenue exceeds a benchmark (e.g., 10% above historical average), cells turn red.
• Highlight Under-forecasted Rows: If Forecasted Revenue is below expected values, cells turn orange.
• Positive vs. Negative Growth Trend (in Dashboard): In the YTD growth chart, positive trends are displayed in green; negative in red.
• Empty Cells Highlight: Missing data cells are automatically flagged with a light gray background to encourage data completeness.
