A fictional personal-account register reconciled to a statement, with pending items, availability, fees and an error-report draft.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • An account-service and annual-fee comparison with unanswered eligibility questions.
  • A posted/available/uncommitted balance worksheet with each commitment counted once.
  • A running-balance register with transaction identities, types and posting states.
  • A two-sided bank reconciliation with an unmatched-item log.
  • A transaction-specific error inquiry and follow-up log.
  • A paper account-move checklist with a retained-funds calculation and closure conditions.

Review and revise

Use these criteria to check your work and choose what to improve.

  • All supplied records reconcile and the decision uses the named case rules.
  • Calculations show units, intermediate values and a second check.
  • Changed-input practice revises the affected result and identifies uncertainty.
  • The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life

This is a new independent statement case, not a continuation of the previous payment-register case. Its transaction T1 is a separate USD 30 transfer and it adds outstanding check C1 for USD 20; do not carry forward the previous case’s USD 50 transfer. This is an original fictional practice case. No account, payment, personal record or outside participation is required. Register closes $325. Statement closes $340; a $20 check is outstanding and a $5 bank fee is missing from the register.

The idea

Explain differences between two records; do not force agreement by inventing an adjustment.

Reconcile a personal bank statement — worked practice

Explain differences between two records; do not force agreement by inventing an adjustment.

This is a new independent statement case, not a continuation of the previous payment-register case. Its transaction T1 is a separate USD 30 transfer and it adds outstanding check C1 for USD 20; do not carry forward the previous case’s USD 50 transfer. Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Register closes $325. Statement closes $340; a $20 check is outstanding and a $5 bank fee is missing from the register.

  1. 1. Step 1: Compare unmatched items by amount and identity

    Match OPEN, D1, G1 and T1 by identity and amount in the two supplied tables; tick matching rows. Put C1 and F1 in the unmatched-item log rather than changing a matched row.

    You should see: One $20 outstanding check and one $5 fee.

    Explain differences between two records; do not force agreement by inventing an adjustment.

  2. 2. Step 2: Adjust the statement for the unpresented check

    Adjust the statement for the unpresented check.

    You should see: 340−20=$320.

    Keep this intermediate result so the final decision can be checked.

  3. 3. Step 3: Record the supported fee in the register

    Record the supported fee in the register.

    You should see: 325−5=$320.

    Keep this intermediate result so the final decision can be checked.

  4. 4. Step 4: Compare corrected totals and retain the difference list

    Compare corrected totals and retain the difference list.

    You should see: Both adjusted balances are $320; reconciliation difference $0.

    Keep this intermediate result so the final decision can be checked.

Now change one thing

The statement also includes a supported $2 fee omitted from the register; statement closing was $338. Adjusted balance?

Your work

What to finish

A two-sided bank reconciliation with an unmatched-item log.

Common mistake

Watch for this

Posting an outstanding check to the register again when it was already recorded.

How can I tell I understand it?

Reconcile a register and bank statement using supported book adjustments and timing differences on a new supplied case, with a visible intermediate check and no unsupported real-world promise.
