How much would a 10% cut in working-age benefits save?
Short answer: About £15.9bn a year saved, before anyone changes their behaviour. After five years, the government is borrowing £23.3bn a year less than if nothing had changed, because the economy and debt interest respond too.
The direct cost
We tested cutting working-age benefit payments by 10% in the first Budget and kept it for the whole term. On paper that brings in about £15.9bn a year. More support helps recipient incomes and demand. It also creates an ongoing cost.
After five years
Direct costings stop at the first year. The game keeps going: prices, jobs, pay, interest rates and debt interest all respond, and some of the money comes back or leaks away.

| NHS access (index, 100 = today) | 100.1 | 100.0 | +0.1 |
Ten years on
Ten years on, the model does not judge the country better off than if nothing had changed: living standards ended up worse.
| Measure | With the change | No change | Difference |
|---|---|---|---|
| Household living standards | 101.68 | 102.85 | −1.17 |
| NHS access | 100.2 | 100.0 | +0.2 |
| Housing, transport, justice and schools | 100.2 | 100.0 | +0.2 |
| Military readiness | 100.0 | 100.0 | 0.0 |
| Size of the economy | 100.03 | 100.00 | +0.03 |
| Debt as a share of the economy | 82.3% | 87.5% | −5.2 pts |
Would voters thank you?
Popularity and results are different tests. Here is how each of the game’s three publics would vote with only this change made.
| Public | With the change | No change |
|---|---|---|
| Services & support | 48.9% | 52.0% |
| Lower taxes | 50.1% | 52.0% |
| Mind the books | 50.6% | 52.0% |
How this was worked out
These figures come from the game’s simplified model, anchored to OBR March 2026 fiscal totals, with no external shocks and every other policy left as inherited. They are illustrative, not an official costing. Real outcomes depend on the wider economy and the choices made alongside. Read the model register for sources and assumptions.
In the game you make five Budgets, face a shuffled deck of world events, and are judged twice: by voters on election night and by the country ten years later.
