About OzTradie Calc

An independent digital utility built to simplify pricing, superannuation, and GST estimates for Australian sole traders and subcontractors.

Our Mission & Purpose

Going out on your own as a sole trader or contractor in Australia is a major career milestone. However, setting a profitable hourly rate is one of the most common stumbling blocks for new electricians, plumbers, builders, painters, and other tradespeople.

Many tradies benchmark their prices solely against competitors, often overlooking critical costs like superannuation, vehicle depreciation, tool replacement, sick leave, and public holidays. This leads to undercharging and financial stress.

OzTradie Calc was developed as an independent, open-access calculator to eliminate the guesswork. We want to make it easy for tradespeople to map out their target annual take-home income, add realistic overheads, and see their required charge-out rate instantly.

Verified Reference Standards

To ensure accuracy for Australian users, our calculations are built strictly around public regulatory guidelines from the Australian government:

  • Superannuation is aligned with the ATO Super Guarantee rate of 12.0% (FY 2025/2026). Source: ATO Super Guarantee.
  • GST calculations are based on the standard 10% Goods and Services Tax, with automatic alerts when estimated business turnover exceeds the legal registration threshold of $75,000. Source: ATO GST Registration Threshold.
