=AVERAGE(B2:B12)

Use case: Finding the average expense per month or average customer spend.

3. IF

The IF function introduces logic into your spreadsheet, allowing conditional calculations.

=IF(C2>1000, “High”, “Low”)

Use case: Classifying expenses or identifying values that exceed budget thresholds.

4. COUNT & COUNTA

COUNT counts numeric values, while COUNTA counts non-empty cells.

=COUNT(D2:D100)

=COUNTA(E2:E100)

Use case: Counting the number of transactions or entries in a log.

6. VLOOKUP

The VLOOKUP function searches for a value in the first column of a range and returns a value in the same row from a specified column.

=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

Use case: Retrieving account information based on account ID or matching vendor names to their details.

7. HLOOKUP

Similar to VLOOKUP, HLOOKUP searches horizontally across the top row.

=HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])

Use case: Finding values in horizontal ledger formats.

8. CONCATENATE / TEXTJOIN

Combine text from different cells to create structured data such as customer full names or custom invoice numbers.

=CONCATENATE(A2, ” “, B2)

=TEXTJOIN(“-“, TRUE, A2, B2, C2)

Use case: Merging first and last names or constructing structured reference IDs.

9. ROUND, ROUNDUP, ROUNDDOWN

Accountants often need to deal with precise decimal values. These functions allow appropriate rounding.t

=ROUND(E2, 2)

=ROUNDUP(F2, 0)

=ROUNDDOWN(G2, 1)

Use case: Formatting values to currency standards or financial reporting accuracy.

10. SUMIF & COUNTIF

Conditional summation and counting allow for filtered data aggregation.

=SUMIF(A2:A100, “>1000”, B2:B100)

=COUNTIF(C2:C100, “Rent”)

Use case: Summing transactions over a threshold or counting specific categories like “Utilities.”

11. INDEX + MATCH

A more flexible alternative to VLOOKUP, especially useful when the lookup value isn’t in the first column.

=INDEX(B2:B100, MATCH(“SearchItem”, A2:A100, 0))

Use case: Retrieving data from tables where columns are not structured for VLOOKUP.

12. IFERROR

Clean up your reports by hiding errors in formulas.

=IFERROR(A2/B2, “Error”)

Use case: Displaying clean results when division by zero or lookup errors occur.

13. INDIRECT

This formula references a range or cell address indirectly, allowing dynamic references.

=INDIRECT(“A” & B1)

Use case: Creating dynamic reports or referencing named ranges that change with input.

14. XLOOKUP (Modern Excel Only)

The XLOOKUP function is a modern replacement for both VLOOKUP and HLOOKUP, offering superior flexibility.

=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found])

Use case: Simplifying complex lookups across datasets in audits and reconciliations.

15. ARRAYFORMULAS & Dynamic Arrays

Use dynamic arrays to automatically fill cells based on a single formula. These include FILTER, UNIQUE, SORT, and SEQUENCE.

Examples:

=FILTER(A2:A100, B2:B100=”Approved”)

=UNIQUE(D2:D100)

Use case: Creating dynamic financial dashboards, filtered transaction logs, or generating unique customer/vendor lists.

16. NPV & IRR

For accountants involved in investment or capital budgeting, these functions are critical.

=NPV(discount_rate, value1, [value2], …)

=IRR(values, [guess])

Use case: Evaluating the profitability of projects or financial decisions over time.

17. EOMONTH & NETWORKDAYS

Essential for calculating project deadlines, payroll schedules, and due dates.

=EOMONTH(TODAY(), 1)

=NETWORKDAYS(A2, B2)

Use case: Payroll cutoff dates or net working days in project delivery.

18. SUMPRODUCT

A powerful formula for weighted averages, multipliers, or combining multiple criteria.

=SUMPRODUCT(A2:A10, B2:B10)

Use case: Calculating weighted costs or KPI scoring metrics.

19. LET

The LET function improves performance and readability by assigning names to calculation results.

=LET(x, A1 + A2, x * 2)

Use case: Complex formulas where interim results need reuse without duplication.

20. LAMBDA

Custom functions created directly in Excel using LAMBDA, making formulas reusable across workbooks.

=LAMBDA(x, x * x)(5)

Use case: Advanced automation and formula abstraction in enterprise-level financial models.
