An interactive costing · Rebuilding Middle Britain
Set every lever the white paper proposes — rates on capital and on earned pay, the spending that reaches middle-income households, and the statutes that decide whether any of it survives contact with reality. Then read the books: surplus or deficit, borrowing, debt, and what lands in a nurse's payslip.
Each section shows its running total. Open any of them.
On individual net worth above the threshold. The Wealth Tax Commission costed 1% above £2m at roughly £16bn a year. Yield peaks near 2.5% and falls beyond it.
The nisab principle — liability attaches only above a high floor, exempting ordinary living assets.
Discount for capital deployed in job-creating enterprise, R&D or green infrastructure.
Aligning capital with labour. Yield turns down past the mid-30s as realisations are deferred.
The other half of the labour–capital asymmetry the paper identifies.
The broadest lever in the system — about £8bn per point. Falls squarely on Middle Britain.
About £2bn per point. Now paid by teachers and sergeants, not only the affluent.
Close to its revenue-maximising point; yield per point is small and falls as the rate climbs.
Main rate between the thresholds. A tax on earned pay alone — never on wealth.
Frozen since 2021. Roughly £6.5bn per £1,000 of unfreezing.
The paper's target is £70,000+. Roughly £1.3bn per £1,000.
Transfers and services aimed at the same cohort. Each carries its own multiplier — childcare and skills raise labour supply as well as demand.
The strongest lever here: it removes a second-earner barrier, so it buys labour supply as well as demand.
Long waits hold working-age people out of the labour force; clearing them returns some of them to it.
The paper's third functional test of middle-class status: accumulating equity through ownership.
Slow-burning, but it is the mechanism by which the mobility ladder is rebuilt.
Cost-of-living relief that reaches commuters directly and shows up fast.
Statutes change what a rate actually collects, and whether the package survives politically. These are the paper's §4.4 and §5.2 recommendations.

Net position
£0.0bnBaseline: £75bn of borrowing, 2.6% of GDP, with net debt at 95.5% and drifting. Your budget moves both lines.
Pounds move from holders with a marginal propensity to consume of 0.05–0.15 to households at 0.60–0.85, and the difference circulates. Baselines are the OBR's.
Effective marginal rate on the next £1 earned — income tax, National Insurance and clawbacks together. The ghost line is today.
Annual change in take-home pay by gross salary. The shaded band is the paper's Middle Britain corridor — 75% to 200% of median, roughly £28,000 to £75,000.
Annual take-home change. Only the last of these pays the wealth tax — that is what the threshold is for.

The paper's §6 test: a package is only as good as its odds of being legislated and staying legislated.
