Reading your statement

What every line, code, and balance on your bank or credit card statement actually means.

A statement is a record written in bank shorthand: two-letter codes, truncated merchant names, and balances that never seem to match each other. This series reads the document top to bottom — the codes, the pending-versus-posted mechanics, the two balances banks show you, and how credit card billing cycles produce the numbers on the page.

None of it requires a finance degree. Every entry is written against official bank and regulator documentation, with the weird lines tied back to real descriptors decoded elsewhere on this site.

Common questions

Why is my statement so hard to read?

Banks compress every transaction into fixed-width lines designed for mainframe-era systems. Codes like POS and ACH describe how money moved, and merchant names are cut to fit — which is why the line rarely tells you the whole story.

Are the codes the same at every bank?

No. ACH, POS, and ATM are near-universal, but banks add their own house codes. The articles in this series cover the common ones and explain how to confirm anything unusual with your bank.
