NumXL review
An Excel-based toolkit for econometrics, time-series modeling, and portfolio measures.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NumXL is a desktop add-in for Microsoft Excel that brings statistical analysis and econometric modeling into workbooks. It is aimed at Excel users, from students to business teams, who want to analyze time-series data, build forecasts, or assess portfolios without moving their work to a separate application. Its methods include regression, statistical and hypothesis tests, ARMA/ARIMA and ARCH/GARCH modeling, data fitting, transformations, sampling, and portfolio measures. Spreadsheet functions and interface wizards support analysis, while workbook results can be shared and calculations traced.
The Excel connection is the product’s defining fit: analyses can be built and updated in workbooks, with tests for normality, autocorrelation, stationarity, and cointegration alongside simple and multiple linear regression. Time-series tools cover seasonal modeling, volatility modeling, transformations, and forecasting; portfolio measures include value at risk, Sharpe ratio, and maximum drawdown. This breadth makes NumXL relevant to users whose statistical work already centers on spreadsheets. It is less suitable for someone seeking an independent statistical application or a workflow not based on Excel.
NumXL requires Microsoft Windows-based Excel. Mac users need to run Windows through virtualization, so the platform requirement is an important constraint before choosing it. The vendor offers a 14-day trial and paid commercial, academic/government/non-profit, and student options. Subscription plans include full features, support, and updates; perpetual options include full features and 12 months of support and updates. The product lists email, chat, and documentation as support channels, and a 30-day money-back guarantee excludes monthly subscriptions. Choose NumXL if Excel is central to your econometrics or forecasting work and Windows is available; look elsewhere if you need Mac-native use or want analysis outside Excel.
