Excel for Accountants: The Formulas and Skills That Matter

Essential Excel skills for accountants and bookkeepers: SUMIFS for ledgers, lookups for reconciliations, ROUND, dates, absolute references and error checks.

By Ayoub Farid · · 1 min read

Accounting work is built on spreadsheets even when there's dedicated software: reconciliations, schedules, accruals, budgets, variance reports. These are the skills accounting roles lean on.

Formulas

TaskFormula
Totals by account or periodSUMIFS
Matching transactions between two listsXLOOKUP, COUNTIFS, compare two columns
Rounding to centsROUND
Aging receivables=TODAY()-C2 with IFS bands
Month end=EOMONTH(A2,0)
Variance=B2-C2 and =(B2-C2)/C2
Checks=SUM(debits)-SUM(credits) should equal 0

Reconciliation in practice

Bank statement in one sheet, ledger in another. For each bank line:

=COUNTIFS(Ledger!$C:$C,C2,Ledger!$A:$A,A2)

Zero means "not in the ledger". Then filter on zero. For amounts within a tolerance, use helper columns with ROUND.

Aging buckets

Days overdue in D2:

=IFS(D2<=30,"0–30",D2<=60,"31–60",D2<=90,"61–90",TRUE,"90+")

Then SUMIF by bucket.

Habits that prevent errors

  • Lock rates and totals with $. See absolute references.
  • Round where amounts must tie out, instead of only formatting.
  • Build check cells (should be zero) and highlight them red if not.
  • Never type numbers into formula columns.

Beyond formulas

Pivot tables for trial balance summaries, Power Query for importing bank or ERP exports, and data validation for consistent account codes.
