Quick Tax Calc

This is a quick calculator for the ATO Australian tax witholding formula.

It's based on Scale 2 - claiming the tax free threshold, no Medicare levy exemption.

Usage

Type your annual pre-tax amount in the income section and see your after tax annual and fortnightly amounts.

You can use the "Save and compare" button to remember a given fortnightly amount for comparison.

The income section also allows for formulae so you can do things like:

• How might a 10% raise affect my income? - 90000 * 1.1
• What if I get an extra job paying 500 a week? - 90000 + 500 * 52
• If I go part time, how much will I get paid? - 90000 * 3/5
• What contractor daily rate is comparable (4 weeks holiday, 2 weeks sick, 10 public holidays, 9.5% super) with my full time salary? - (448 * 5 * (52 - 4 - 2 - 2)) / 1.095

Roadmap

I might add the ability to work backwards - I want to earn 3000 a fortnight, how much do I need to earn?
