Business income and tax calculator

How it works

When you run your own business, you need to figure out how much money you need to make to cover everything - your personal income, business expenses, taxes, and still have some profit left over.

What you tell it:

  • How much profit you want your business to keep
  • How much you want to pay yourself personally
  • How much it costs to run your business
  • How much you pay other people to help you

What it calculates:

  • Based on your income, it figures out how much tax you'll owe (income tax, Medicare levy, and potentially a surcharge if you don't have private hospital cover)
  • It adds up everything you need plus taxes to figure out your total gross revenue target

Smart adjustments: Tax is deducted from owner's pay. If your profit is high and tax exceeds owner's pay, then tax is deducted from your profit.

What you get:

  • A clear breakdown showing exactly where all your money goes
  • The total amount you need to earn to meet your goals
  • The ability to see this as monthly or yearly targets
  • Real-time updates as you adjust your goals

Thriday has been amazing to use as a small business owner. I love the allocations that allow funds to automatically transfer across accounts and even out to external accounts. Customer service has always been great (and Aussies, not people from overseas). I even had a free consultation about taxes that was super helpful. I highly recommend Thriday for any small business owner!
