Disclaimer

  • Educational only. Not advice. No guarantees.
  • Results depend on your inputs and assumptions.
  • See the Privacy Policy for handling details.

What the tool includes

  • Income change (as you enter it) for the period you choose.
  • Category spend and weights based on your inputs.
  • Category inflation assumptions you set.
  • Personal inflation, real income change, and a gap estimate using your basket.
  • Scenario saving and PDF exports as snapshots.

What it excludes

  • Taxes, benefits, and detailed deductions.
  • Debt terms, interest schedules, or amortization.
  • Unlisted categories or one-off shocks unless you add them.
  • Forecasts of future prices or wages.
  • Real-time updates—exports are snapshots.

Why outputs differ from lived experience

Your own prices, timing, and taxes may differ from the simplified inputs. If a category spikes mid-year or a bonus arrives off-cycle, the tool won’t mirror that unless you enter it. Personal inflation depends on your weights and assumptions, which may not match official CPI or your exact bills.

How to use results safely

  • Use conservative, rounded inputs.
  • Compare scenarios one change at a time.
  • Rerun when assumptions change.
  • Avoid false precision; focus on direction, not exact decimals.

Run scenarios with limits in mind

Enter your basket, stay conservative, and compare scenarios directionally.

Why might outputs differ from reality?

Inputs are simplified, and your actual prices or timing may differ from the assumptions you set.

How should I use results?

Directionally. Compare scenarios, use conservative inputs, and avoid over-relying on precise decimals.

Is this advice?

No. It is educational. Results depend on your inputs and assumptions. No guarantees.
