Deficit and debt. Total borrowing is the current budget deficit plus net investment. The current budget includes depreciation and excludes net investment. National debt is the accumulated stock.

Current budget deficit: —. Day-to-day balance, excluding net investment. Net investment: —. . Financial year to date

Fiscal rule. The current-budget fiscal mandate concerns the forecast balance in its target year. A year-to-date forecast gap is not a verdict on whether the rule is met.

Reporting periods. Headline income and spending cover the whole UK public sector. The monthly breakdown covers central government. Service spending is annual; the OBR figure is a full-year forecast.

Published estimates. Monthly ONS figures use accruals accounting and can be revised. Same-period comparisons account for seasonal tax receipts. Borrowing includes net investment.
