About this calculator

Marginal rate = tax on the next dollar earned. Average rate = total tax divided by total income. Marginal jumps at each NZ bracket boundary (10.5/17.5/30/33/39); average climbs smoothly. Add 1.6% ACC up to the cap and the picture shifts again.

  • Marginal rate is what matters for "is this raise / overtime / bonus worth it?" decisions.
  • Average rate is what matters for budgeting take-home pay.
  • Above the ACC cap (~$142k) the marginal rate flattens because ACC stops accruing.
