Run a federal budget forward

Budget Build Projector

AI GENERATED · A PROJECTION FROM YOUR OWN CHOICES, NOT A FORECAST

The projector starts from the real 2024 debt and runs a budget from Budget Build Forge one federal quarter at a time, showing the money in, the money out, the interest, the shortfall and the debt.

How to use this page — step by step

Run a budget

  • Pick a budget you saved on Budget Build Forge, or open a budget link someone sent you, then choose how many quarters to look ahead and press Run the projection.
  • Run a second budget and press Compare with the last run to see the two side by side.

Read the results

  • The government's budget year starts in October, so quarter 1 of budget year 2025 is October to December 2024, the first quarter after the last real figures.
  • The tiles show where the budget ends up: the debt, the debt as a share of everything the country earns in a year, all the shortfalls added up, and all the interest paid.
  • The first chart shows money in, money out and interest every quarter. The second shows the debt as a share of the economy.
  • A quarter that brings in more than it spends is outlined in green.

What it leaves out

  • It does not know that a tax change can change how fast the economy grows, so the growth you pick stays the same whatever the budget does.
  • Money is spread evenly across the year, so the real swings around tax deadlines are smoothed out.
