Excel Formulas & Functions For Dummies, 5th Edition

Excel formulas can do far more than add a column of numbers. Ken Bluttman’s Excel Formulas & Functions For Dummies, 5th Edition shows how to build formulas, choose useful functions, and apply them to everyday calculations and data problems. Centered on Excel 2019, the book offers a hands-on route from formula fundamentals to more specialized tools.

Start with the logic behind a formula

Early chapters cover worksheets, cell references, formula construction, function arguments, arrays, and the tools Excel provides for entering and checking calculations. There is also practical attention to common formula errors, broken links, circular references, and formula auditing—helpful territory when a spreadsheet stops behaving as expected.

Put calculations to work

The book moves from core math functions such as SUM and rounding to more involved calculations with random numbers, conditional sums, products, and trigonometry. Dedicated chapters explore loan payments, interest rates, principal, and depreciation, connecting Excel functions to financial questions and schedules.

Make sense of data and decisions

Statistics receives substantial attention, including averages, variation, distributions, percentiles, significance tests, probability, and prediction. Later sections turn to date and time calculations, lookup and reference functions, logical tests, text handling, and database functions. This range helps readers see how the right formula can support both routine worksheet tasks and more focused analysis.

A useful reference for learning as you go

Organized in five parts and ending with practical tips and selected functions, this guide suits beginning to intermediate Excel users who want to understand what a formula is doing—not simply paste one into a cell. Keep it nearby when building a new worksheet, checking a calculation, or looking for a function suited to the task. 📊
