At some point, your tracked balance will drift slightly from what your bank account actually shows — a forgotten cash payment, a small purchase that never got logged, a transaction that slipped past unnoticed. When this happens, the right response is simply to correct it, not to feel like you've failed at tracking.
Here's why this drift is completely normal rather than a sign of doing something wrong. Nobody logs every single transaction with perfect completeness, every single time, forever — small gaps are a near-universal part of manual tracking, no matter how disciplined the habit. The honest fix isn't to retroactively hunt down exactly which forgotten purchase caused the gap; it's simply to correct the balance to match reality, acknowledging that some detail was lost along the way without needing to reconstruct it.
This is genuinely different from logging a transaction — a reconciliation isn't pretending a specific purchase happened on a specific day with a specific category. It's a quiet, honest correction: "the real balance is this; some untracked spending explains the difference, and that's fine." Your account balance becomes accurate again, while your spending categories aren't distorted by a guessed, possibly wrong, retroactive entry.
The practical habit: whenever you notice a gap between your tracked balance and your actual bank balance, reconcile it promptly rather than letting it linger or feeling bad about it. A quick, guilt-free correction keeps your net worth honest and your tracking trustworthy — which is the entire point, far more than perfect, gapless logging ever needs to be.
