Sheet
Download the file.
This page is the sheet. It uses the numbers in the link. The $39 button on the previous page is the paid copy: same arithmetic, plus the Stripe receipt if you want a human to check it. You do not need to pay to read the file.
Planning arithmetic, not tax advice. Refund: reply to the Stripe receipt within 7 days. A human rewrite is optional: kepthour.brief@gmail.com with the receipt.
