Scenarios at £125,140
Children under 5, a buffer under the line, and what a rise from here is worth.
By children under 5
| Children under 5 | Cash a year | Child Benefit charge | Childcare support kept | Sacrifice to £100k | Better off after it |
|---|---|---|---|---|---|
| None | £78,111 | — | — | £25,140 | +£15,587 |
| One child | £78,111 | −£1,407 | £0 | £25,140 | +£26,137 |
| 2 children | £78,111 | −£2,337 | £0 | £25,140 | +£36,687 |
Cash is take-home plus Child Benefit less the charge. For the example children aged 9 months to 2, childcare support is £0 while adjusted net income is over £100,000; the sacrifice brings it back, and the pension money stays yours.
Buffers under £100,000
| Target | Sacrifice a year | A month | Take-home change | Into your pension |
|---|---|---|---|---|
| £100,000 exactly | £25,140 | £2,095 | −£9,553 | +£25,140 |
| £98,000 (£2,000 buffer) | £27,140 | £2,262 | −£10,713 | +£27,140 |
| £95,000 (£5,000 buffer) | £30,140 | £2,512 | −£12,453 | +£30,140 |
A buffer covers income you can't control before 5 April: a bonus, savings interest, a benefit in kind. Through a personal pension instead, pay in 80% of the sacrifice and the provider grosses it up.
Your next £1,000, £5,000 and £10,000
| Extra salary | Kept, no children | Kept, one child under 5 |
|---|---|---|
| +£1,000 | £530 (53%) | £530 (53%) |
| +£5,000 | £2,650 (53%) | £2,650 (53%) |
| +£10,000 | £5,300 (53%) | £5,300 (53%) |
After income tax, NI and the Child Benefit charge. The one-child column also counts childcare support lost or kept when the extra crosses £100,000, which is why it can go negative.
