A free FTB calculator and estimator for Australian families — work out your Family Tax Benefit Part A and Part B for 2026–27
Use this Family Tax Benefit calculator to estimate your FTB Part A and Part B payments from your family income and number of children. It applies the same Centrelink family income estimate that Services Australia uses, so you can check your entitlement before you lodge.
Part B is income-tested on the lower earner, not the household. Leave at 0 for a single-income couple.

Part A income test applied: Your family income has reduced FTB Part A to the base rate, where it stays until the higher income threshold.
Part A supplement not included: The FTB Part A supplement is only paid where family income is $80,000 or less, so it is excluded from this estimate. The Part B supplement has no equivalent income limit — it sits inside the Part B rate and is reduced by the secondary earner test rather than cut off.
Based on 2026-27 FTB rates and thresholds from Services Australia. Rates last checked 6 August 2026. This is an independent estimate, not an official Centrelink figure.

The maximum FTB Part A rate is $235.48 a fortnight for each child under 13 and $306.46 for each child aged 13 or over. You get the maximum rate while your combined family income is $69,131 or less, then it reduces by 20c in the dollar down to a base rate of $75.60 per child.
FTB Part B adds up to $200.34 a fortnight where your youngest child is under 5, or $139.86 where they are 5 or older. It is income-tested on the lower earner and stops entirely once the higher earner passes $124,327. Enter your details above for an estimate based on your own circumstances.

Every row below is the same family — a couple with two children aged 5 and 8, on a single income — so the only thing changing is the income test. The incomes are the thresholds themselves rather than round numbers, because that is where the answer changes. Figures are annual and come from the same calculator above.

Your own answer moves with the number of children, their ages and how the income is split between two earners, which is what the calculator is for.
The figure above applies the Part A and Part B income tests to the family you described. Services Australia applies more than the income tests, and several payments are made alongside Family Tax Benefit rather than inside it. Here is everything that sits between the estimate and the amount that reaches your account, so you can see which of it applies to you before you rely on the number.
Three mechanics reduce Family Tax Benefit for circumstances the calculator has no way to know about. All are common, and all are handled by Services Australia rather than by any income figure you enter here.
Several payments are made together with Family Tax Benefit Part A rather than as separate claims. None is included in the figure above, so a family in one of these situations may receive more than the calculator shows — each has conditions of its own, and the first two are the ones most often assumed to be automatic.
The remaining differences are assumptions rather than omissions. Each one is the ordinary case, and each one is worth a moment's check against your own circumstances.
None of the above changes the rates this calculator applies — they are the 2026–27 figures, last checked against Services Australia on 6 August 2026. They change who those rates are paid to and what else is paid with them, which is why two families on identical incomes can receive quite different amounts. The rules themselves are set out by Services Australia and in full detail in the Family Assistance Guide, which is the policy guide of record — go there for any threshold or percentage, none of which are quoted above on purpose.

Family Tax Benefit (FTB) is a payment from the Australian Government to help families with the cost of raising children. It has two parts: FTB Part A is paid per child, and FTB Part B provides extra support for single parents and single-income families.
The amount you receive depends on your family income, the number and ages of your children and your family circumstances. Payments can be received fortnightly or as a lump sum at tax time.
They are two separate payments and most eligible families receive both. Part A is paid per child and is income-tested on your COMBINED family income — it starts reducing above $69,131. Part B is paid per family rather than per child, and is aimed at single parents and single-income couples: it is income-tested on the LOWER earner, who can earn $7,154 before it starts reducing, and no Part B is payable at all where the higher earner is above $124,327. So a couple on one modest income often receives both, a dual-income couple frequently receives Part A only, and the two are assessed independently. This calculator works out each one and shows them separately.
FTB Part A is worked out per child based on the child's age and your combined family income. It's paid at the maximum rate while family income is $69,131 or less, then reduces by 20c in the dollar down to a base rate of $75.60 per child per fortnight. Above $123,078 that base rate reduces again by 30c in the dollar. This Family Tax Benefit calculator applies both income tests and pays whichever gives the higher result, the same way Services Australia does.
FTB Part B is up to $200.34 a fortnight where your youngest child is under 5, or $139.86 where they are 5 or older. It's aimed at single parents and single-income families. No Part B is payable if the higher earner's income is above $124,327, and couples stop receiving it once the youngest child turns 13. Single parents and carers keep it for longer.
It uses the same family income estimate that Centrelink (Services Australia) applies to Family Tax Benefit, so it's a useful way to estimate your payments before you lodge. It's an independent estimate, not an official Centrelink figure — confirm your entitlement through myGov.
Yes. This Family Tax Benefit estimator uses the 2026–27 rates and thresholds that applied from 1 July 2026, sourced from Services Australia and the Family Assistance Guide. FTB rates are indexed every 1 July, and this calculator is refreshed each time they change.
Yes. FTB Part A is based on combined family income, so both incomes count. FTB Part B is different — it's income-tested on the lower earner, who can earn $7,154 a year before Part B starts reducing by 20c in the dollar. Enter the lower earner's income above for an accurate Part B estimate.

At tax time, Services Australia compares your estimated income to actual income. Overpayments must be repaid, either as a deduction from future payments or as a debt.

This calculator exists to show you the arithmetic. It applies published Australian rates, thresholds and formulas to the numbers you enter and shows the working, so you can check it. That is all it does — it produces a number and describes what the number is. It does not recommend anything and it holds no opinion about any financial product.
