Adds GST on top of the quote. GST is never treated as your revenue.

Capacity and cost assumptions

These open at the modelled defaults. The year starts from 260 weekdays, and everything you enter here is subtracted from it or priced into the rate.

Summary

Enter a target annual income to see the day rate and the working behind it.

Working

  1. capacity days = 260 − public holidays − annual leave − personal leave − non-billable days
  2. billable days = capacity days × utilisation
  3. super replacement = target income × super replacement rate
  4. break-even revenue = target income + super replacement + annual overheads
  5. target revenue = break-even revenue × (1 + risk margin)
  6. target day rate = target revenue ÷ billable days
  7. hourly equivalent = target day rate ÷ hours per billable day
  8. GST, when registered, is added to the day rate and shown separately

Assumptions

  • Every figure on this route is your own entry or an editable default. Nothing here is a published rate or an award condition.
  • Utilisation applies to the days that remain after leave and non-billable days, so it is not double-counted.
  • Super replacement is money set aside, not spendable income, and no contribution cap or tax treatment is applied.
  • GST collected is held for the ATO and is never counted as revenue in any figure above.

Limitations

  • Income tax, PAYG instalments, deductions, entity structure and personal services income rules are out of scope.
  • Insurance, workers compensation, licensing obligations and superannuation guarantee obligations to others are not assessed.
  • Whether you are or must be registered for GST is your selection, not a determination made here.
  • Result accuracy class B: a capacity model built entirely on the assumptions you set.
