Each £1 of qualifying gross pension contribution can reduce adjusted net income by £1. That makes pension one of the most practical levers for people sitting just above the £100,000 ANI line.
Worked examples
These examples focus on the planning question most readers have: how far above £100,000 are you, and what gross pension amount could close that gap?
ANI £101,500
About £1,500 gross may be needed. A relatively small contribution can be enough when the ANI gap is narrow.
Why it matters: near the line, small changes can have outsized threshold effects.
ANI £104,000
About £4,000 gross may be needed. This is the simple “close the gap to £100,000” logic many users want.
Why it matters: the page turns a tax threshold into an actionable pension figure.
ANI £112,000
The gross amount needed becomes much larger. The page is still directionally useful, but the wider pension-planning decision becomes more significant.
Why it matters: a larger gap usually means the decision is no longer just a quick threshold tidy-up.
Comparing gross and net cost
The cash cost is not the same as the gross figure. HMRC rules use the gross amount for ANI, but many users also want to understand what that could mean in real out-of-pocket terms.
Why it matters: showing both numbers makes the planning choice easier to understand.
Why the page shows gross and net
Readers usually want two answers at once: the gross contribution that changes ANI and the real-world cost of making it.
ANI moves with the gross contribution amount
HMRC’s ANI method works from the gross amount that counts for relief. That is why the calculator focuses on the gross contribution needed to get back to the threshold.
Use the gross gap to estimate the threshold fix
If your ANI is £103,000, the planning question is often whether you are comfortable making a gross contribution of roughly £3,000 rather than just thinking vaguely about “paying more into pension”.
Why readers like this page
- It turns ANI into a practical pension target
- It makes the £100k issue feel solvable
- It links straight to the connected taper pages
What this page is not
- It is not full pension advice
- It is not an annual allowance check
- It is not a replacement for personalised planning
What this page does not cover
These caveats matter because pension planning can be broader than the narrow threshold question this page is solving.
Assuming the threshold question is the whole pension decision
This page is here to answer one focused ANI question. It does not replace checking annual allowance, carry forward, salary sacrifice setup or wider retirement planning.
Using the wrong contribution basis
The page uses the gross amount for ANI logic. Readers can become confused if they compare that directly with a net amount paid from take-home pay.
Use this result with the £100k and ANI pages, not in isolation
That gives you the full picture: how far over the line you are, what contribution could change it, and what the allowance taper looks like before and after.

Questions people usually ask
Does every £1 of gross pension reduce ANI by £1?
For qualifying contributions used in ANI calculations, that is the core rule of thumb this page follows.
Why does the page show gross and net?
Because the threshold logic uses gross contributions, but many readers also want a practical view of the likely cash cost.
Is this page pension advice?
No. It is a threshold-focused estimate page, not full pension or financial advice.
