Monthly Personal Budget Sheet
August 2026 Cashflow Plan
A monthly plan, not a locked report
Budgets change when a bill, trip, or pay date changes. Keep the assumptions visible and revise the same page.
01Start with your categories
A blank spreadsheet can hide the decisions behind the totals.
Write each income and spending line in context.
02See the remaining amount
A balance may not show which category caused the change.
Keep linked subtotals and the remaining amount together.
03Reuse next month
A new month often means rebuilding the same layout.
Copy the page and change the new month’s inputs.
