Why might my Centrelink payment differ from this calculator estimate?

Discrepancies usually occur if your actual annual income differs from your estimate, if salary packaging or fringe benefits are grossed up differently, if maintenance payments fluctuate, or if child care percentages change mid-year.

How do I avoid getting a Centrelink FTB overpayment debt?

To avoid an overpayment debt, slightly overestimate your family's annual income, choose to receive the base rate during the year, or opt for an annual lump sum payment at tax time rather than fortnightly instalments.

How does shared care affect my FTB payment?

Services Australia uses a statutory sliding scale. You must have at least 35% care to receive a percentage of the FTB child payment rate. For 35% to <48% care, the payment is 25% plus 2 percentage points per care point above 35%. Equal care (48%–52%) receives 50%, 53% to 65% care follows a progressive formula (e.g. 65% care yields 75% FTB), and more than 65% care receives 100% FTB.
