Added October 15, 2026. Written with AI assistance and checked for clarity and placeholders; not reviewed by a lawyer, accountant, clinician or other professional. How these prompts are made
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
[VERIFY] is an editorial flag, not a blank to fill. Wherever the prompt shows [VERIFY], check that item against a reliable source before you use it (what [VERIFY] means).
Help me audit my credit card statement. The statement lines: previous balance, payments, purchases, fees, interest charged, new balance, minimum payment, APR, and payment due date: [STATEMENT_LINES]. My usual payment: [MY_PAYMENT]. Check the arithmetic: previous balance minus payments plus purchases plus fees plus interest equals the new balance. Explain each line in plain words. Estimate the monthly interest from the balance and APR (balance times APR divided by 12) and compare with the interest charged, noting that exact methods vary by issuer [VERIFY]. Show the effect of paying the minimum versus a fixed higher amount over six months with a small table. List questions to ask the issuer about any fee or charge I do not understand. Education only, not financial advice. Do not include account numbers. Add a worked six-month example: balance 1,800, APR 21 percent, minimum payment 54 (3 percent): month one interest is 1,800 x 0.21 / 12 = 31.50, payment 54, new balance 1,777.50; compare paying a fixed 150 a month and show the months to clear for each with a note that the minimum falls as the balance falls.
