Formula
If repayment income < $54,435: repayment = $0. Otherwise apply the ATO threshold band: income × rate for the band. Bands: $54,435–$62,849 at 1.0%; $62,850–$66,619 at 2.0%; $66,620–$70,618 at 2.5%; $70,619–$74,855 at 3.0%; $74,856–$79,347 at 3.5%; $79,348–$83,241 at 4.0%; $83,242–$87,580 at 4.5%; $87,581–$91,980 at 5.0%; $91,981–$96,640 at 5.5%; $96,641–$101,899 at 6.0%; $101,900–$107,214 at 6.5%; $107,215–$112,585 at 7.0%; $112,586–$118,119 at 7.5%; $118,120–$123,861 at 8.0%; $123,862–$129,825 at 8.5%; $129,826–$135,630 at 9.0%; $135,631–$141,848 at 9.5%; above $141,849 at 10.0%. Fortnightly = annual ÷ 26. Weekly = annual ÷ 52. Years to repay = debt ÷ annual repayment (assuming no indexation).
