Each route adds £4,500 to your pension. Real cost is what you’re out of pocket after tax relief (and National Insurance, for salary sacrifice). How we calculate
Salary sacrifice also saves National Insurance. With a workplace pension, tax relief comes through your pay. With a personal pension or SIPP you pay first; your provider adds 20% and you claim the rest on your tax return.
Pay into a personal pension or SIPP by 5 April to count for this tax year. Check your provider’s payment timing.
Start with salary, bonus, self-employed profit, taxable benefits and full other income. Subtract salary sacrifice and workplace pension contributions. Subtract personal pension cash and Gift Aid after multiplying each by 1.25.
Each parent’s ANI must be at or below £100,000. We check minimum earnings separately, before pension payments or Gift Aid.
We compare income tax before and after each top-up to find the tax relief. Salary sacrifice can also save National Insurance. The childcare comparison uses your hourly value and paid bill, or the maximum Tax-Free Childcare amount when no bill is entered.
Scottish rates, separate savings and dividend taxes, pension limits and individual payroll arrangements need a closer check.

The upper income limit applies to each parent’s ANI, rather than salary alone. Bonuses, taxable benefits and full other income count. Existing pensions and grossed-up Gift Aid can reduce ANI.
In England, eligible children from nine months to two years can lose all 30 working-parent hours. Children aged three to four retain 15 universal hours, so the additional hours at stake are lower. The calculator values the hours using your hourly rate and adds Tax-Free Childcare separately.
For Wales, Scotland and Northern Ireland it counts Tax-Free Childcare only: free-hours rules differ. Where no paid childcare bill is entered, the displayed value is “up to” the annual cap.
Tax relief comes from the difference between income tax before and after the gross contribution. It is not a fixed cost per pound. Salary sacrifice can also save employee National Insurance; a SIPP needs an upfront cash payment followed by a provider top-up and any further tax refund.
FAQ
Straight answers to the questions parents usually ask when they are trying to protect 30 hours free childcare or Tax-Free Childcare.
Yes. Each parent must be at or below £100,000 adjusted net income. A top-up by one parent does not fix a partner who remains over the limit.
Yes. You need at least £10,569 a year if you are aged 21 or over. It checks salary plus bonus and expected self-employed profit before deductions, not ANI. Other age bands have separate minimums. The official test uses expected earnings over the next three months and has exceptions. ANI alone does not establish eligibility.
Eligible children from nine months to two years risk all 30 working-parent hours. Children aged three to four retain 15 universal hours. The calculator values the additional hours at stake separately from Tax-Free Childcare.
Free-hours rules differ. This calculator counts Tax-Free Childcare only outside England. Tax estimates use rates for England, Wales and Northern Ireland. Scottish rates need a separate check.
Enter the cash actually paid. It is multiplied by 1.25 for the gross ANI reduction. The provider top-up is separate from any further tax relief claimed through Self Assessment.
Include full savings interest, dividends and rental profit, including amounts covered by savings or dividend allowances. Add taxable benefits as well as salary and bonus.
From April 2029, the £2,000 salary sacrifice pension cap concerns National Insurance relief only. ANI treatment is unchanged. The current-year calculator does not apply that future NI cap.
Payments must be made by 5 April to count for this tax year. Check your provider’s processing timing. Do not confuse the cash payment with the gross pension contribution.
For a bill entered, the planning value is 20% of paid childcare, limited to £2,000 per child, or £4,000 for a disabled child. Without a bill it is labelled up to the cap. Reconfirm details every 3 months; confirm actual entitlement and timing with the official service.
