How this cash flow calculator works

List your regular expenses, from rent and utilities to groceries and subscriptions, and set how often each one is paid. The calculator converts everything to the period you choose, so quarterly and yearly bills are spread out rather than forgotten. The total is compared with your take-home pay to show what is left over each week, fortnight, month or year.

Why start from take-home pay?

A budget built on your gross salary overstates what you can spend. Income tax, the Medicare levy and any HECS/HELP repayment come out before the money reaches you. This calculator starts from your pay after tax, so the leftover figure matches what actually arrives in your bank account.

Your entries stay on your device

What you type is saved in your browser so it is still here when you come back, and each month is kept separately. Nothing is sent to a server.

What this tab leaves to the others

This is the one tab on the site that faces spending rather than earning. It does not work out tax, super or loan repayments; it takes the after-tax figure those tabs produce and asks what happens to it once it lands. If the take-home number itself looks wrong, the place to investigate is the pay calculator, not here.

It also does not know what things cost. The market averages shown beside a few expenses are broad estimates for orientation, never added into your totals, and your own entries are the only numbers that drive the result. Treat the output as a mirror of a routine month rather than a ledger of everything: a windfall, an emergency or an annual holiday will pass straight through it unless you give it a row.

Frequently Asked Questions

How is my take-home pay calculated?

Your take-home pay is gross income minus income tax, Medicare Levy, and HECS repayment. Super is paid by your employer on top, so it does not reduce your take-home pay.

Why does my result differ from my payslip?

Payslips use ATO PAYG withholding tables which round to weekly/fortnightly cycles. Small differences are normal and reconciled at tax return time.

Can I compare 2025–26 and 2026–27 rates?

Yes. Use the Tax Year selector above the calculator. From 1 July 2026, the $18,201–$45,000 bracket dropped from 16% to 15%, saving up to $268 per year.

Are these calculations an estimate?

Yes. Results are accurate estimates based on ATO rates. They do not account for individual deductions or investment income. Salary sacrifice to super is supported on the Full-time tab. Consult a registered tax agent for personalised advice.

How accurate is this calculator?

Very accurate for standard employees. Uses ATO official rates, the 2025–26/2026–27 HECS marginal system, and 12% Super Guarantee. Differences may occur with deductions, FBT, or investment income.

How often is the calculator updated?

Rates are reviewed each July when the ATO publishes new rates. An automated monitor checks for ATO changes and notifies the team. Report discrepancies using the feedback button.
