The calculator applies the current published eldest-or-only-child and additional-child weekly rates. It is not a benefits entitlement decision and does not decide claim responsibility, child age rules or education and training status.
Use the curated examples to compare the published Child Benefit rate for one, two or three children before checking whether a higher-income household may also need a HICBC estimate.

Read the result and assumptions first, then use the related calculators only when you need to change inputs or continue into a wider plan.
PayBreakdown is an informational calculator and household-finance modelling tool. It does not provide legal, tax, employment, payroll, benefits, lending, accounting or regulated financial advice.
Check whether the page uses a fixed scenario, a simple default, or your own local inputs. Fixed scenarios are useful for orientation, but personal decisions should use current payslips, bills, provider documents, official sources, and professional support where the decision is important.
A useful estimate shows the key inputs, the calculation area, the assumptions and the limits in the same place. If a page does not match the user situation exactly, use it to understand direction and sensitivity first, then move into the relevant calculator or local workspace to adjust the numbers.
Use the visible result as a starting point, then change the assumptions that apply to your situation. For salary pages, that usually means tax year, region, tax code, pension method, student loan plan, bonus, overtime and salary-sacrifice settings. For borrowing, debt or budget pages, it means the real payment amount, term, interest rate, balance, bill timing, savings target and any expected income change. Keep the result separate from advice or approval decisions: PayBreakdown helps you model the numbers, while official sources, employer records, provider documents and professional support are still the right place for final checks. If a change is close to a threshold, rerun the calculation with a cautious higher-cost or lower-income scenario before relying on the result.

For the 2026/27 source data used here, the calculator applies the eldest-or-only-child weekly rate and shows the weekly, four-weekly and annual estimate.
It applies the eldest-or-only-child rate to the first child and the additional-child rate to each extra child, then converts the weekly total into four-weekly and annual amounts.
No. This is a rate estimate only. Eligibility depends on responsibility for the child, age and education or training rules, and only one claim can be made for a child.
Check the HICBC calculator if the claimant or their partner may have adjusted net income above the current charge threshold.
