What If We Have Another Child?
England’s 30 funded hours have applied from nine months since September 2025. You can still claim Child Benefit, Tax-Free Childcare and funded hours together if you meet each scheme’s tests. HICBC claws back Child Benefit on the higher earner’s adjusted net income from £60,000 to £80,000 — not the household total. Tax-Free Childcare and funded hours cut off at £100,000 adjusted net income per parent, as a cliff, not a taper. A child-birth milestone puts those rules on the same years as the mortgage and later retirement.
A journey can hold this event and later ones. Two free journeys, 15-year cap. Paid paths run 30 years.
Then The Events That Follow
This question starts the journey. Add later events on the same years so tax, leftover cash, childcare and retirement move together. A calculator answers one slice. Free paths run 15 years; paid unlocks run 30.
How Kumberi Models Another Child
You Enter Costs; The Engine Applies The Gates
The child-birth milestone carries arrival timing, extra monthly costs, optional childcare, funded-hours nation (England 15/30-hour style when that nation is selected), Tax-Free Childcare, and maternity or shared parental leave weeks. Nursery prices are whatever you type. How free hours and Tax-Free Childcare reduce those costs is documented in Funded Childcare.
HICBC Follows The Higher Earner, Not The Household Sum
Child Benefit is modelled with the High Income Child Benefit Charge. HICBC follows the higher earner’s adjusted net income against a £60,000–£80,000 taper — not both salaries added together. Crossing those bands changes net Child Benefit in cash flow. Tax-year assumptions are in Calculation Methodology.
The £100,000 Gate Can Change Nursery Net Cost
Funded hours and Tax-Free Childcare eligibility use the income gates in the engine, including the personal-allowance / Tax-Free Childcare interaction around £100,000 adjusted net income. A pay change in the same journey can change childcare net cost. Student loans keep calculating on each earner.
Nursery Maths Without Tax Is Incomplete
A childcare spreadsheet will not apply HICBC, funded hours or the Tax-Free Childcare income gate, and it will not show whether the extra outflow delays ISA funding. Household cash flow can sketch a typical month; the journey is where leave, benefits and later years sit together.
Read Funded ChildcareWhat This Page Does Not Model
- Funded-hours rules differ by nation. The child milestone lets you set a childcare nation; do not assume a Scottish or Welsh entitlement matches the England 15/30-hour story without checking what you entered. See Funded Childcare.
- The model does not apply for Child Benefit or Tax-Free Childcare on your behalf. It illustrates cash flow if those items are in the journey.
- Marriage allowance is not an automatic transfer. Student loans continue on each earner’s income as modelled.
Common Questions
Does Kumberi Recommend Having Another Child?
No. Family size is not a modelled recommendation. The product illustrates cash flow, tax and childcare rules under the assumptions you enter.
How Does HICBC Work In The Model?
HICBC follows the higher earner’s adjusted net income against the £60,000–£80,000 taper. It is not the simple sum of both salaries. Inspect the tax year in the result. Childcare gates are explained in Funded Childcare.
Are The 15 And 30 Funded Hours Included?
You can assume funded hours on the child-birth milestone (England 15/30-hour style when that nation is selected). The engine applies the product’s funded-hours and Tax-Free Childcare gates to the childcare cost you entered. It is not a local-authority application.
