What the figures on the Scenarios and Tax Impact tabs mean.
SavingTax shows your results in two places on Home: the Scenarios tab, for a what-if you’re trying, and the Tax Impact tab, for the plan you’ve saved. All figures are estimates.
On the Scenarios tab
- Estimated tax benefit: the tax this scenario could save you, at the top.
- Original tax and Adjusted Income: where you start, before the scenario.
- New tax and Net position: where you’d end up with it.
- Achieved Rate: your effective tax rate with the scenario. It can differ from the target you set. Tap the i next to it to see why.
- Tax-saving plan: the contributions the scenario suggests for each option. Tap the i to see how they’re worked out, and How is this calculated? for the detail.
- Scenario impact: a side-by-side of No Plan, Saved Plan and What If, with Overall Tax, Tax Saving and Overall Tax Rate.
If some budget shows as unallocated, tap the i beside it to see why.

On the Tax Impact tab
- Tax without plan, Tax with plan and Effective rate: the headline comparison.
- Short notes such as Avoids Child Benefit tax charge or Restores Personal Allowance, when your plan achieves them.
- Total relief generated, and where it goes: the tax you save, top-ups added to your pensions and ISAs, and the Gift Aid top-up that goes to charity.
- How adjusted net income is worked out, if you want to see the steps.

Remember
These are estimates based on what you entered and on HMRC rates for the tax year. They aren’t a recommendation or personal financial advice.
