The monthly reconciliation is the single habit that separates households with financial control from those without. It takes thirty minutes and it produces every downstream artifact: the budget, the net-worth update, the tax preparation. Adopt it, or your financial planning is theater.
- 01Perform a monthly reconciliation from bank exports.
- 02Identify and correct the three most common reconciliation errors.
- 03Produce a one-page monthly report.
The procedure
On the first weekend of each month, download the previous month's transactions from each account. Categorize them. Sum by category. Compare the total change in balances to the sum of income minus expenses. Investigate any gap larger than the smaller of $50 or one percent of monthly spend.
The three errors
Timing — a transaction that cleared on the first of the month but was authorized on the last day of the previous. Transfers counted as expenses — moving money between your accounts is not spending. Missed reimbursements — an expense that will be reversed and should be flagged, not recorded.
The report
One page. Net income for the month. Spend by category. Delta versus the same month last year. A note on the one thing that surprised you. Anything longer will not be read again next month.
- Thirty minutes on the first weekend of the month. Non-negotiable.
- One-page report or nothing. Length is the enemy of continuity.
