How to use the calculator
- Select the “From Date” — this is the first day of the income period.
- Select the “To Date” — this is the last day of the income period (must be the same or later than the From Date).
- Enter the Net Amount Earned ($) — that’s the total income you received between the From and To dates.
- Your results will show:
- Days worked (inclusive of both From and To dates)
- Estimated Monthly Income — how much you’d earn per month, on average, based on the period and the net amount entered.
- Estimated Annual Income — how much you’d earn in a 12-month year, based on your entered data.
Why this matters
Whether you’re applying for a loan, assessing your business income, or simply planning ahead, knowing your monthly or annual equivalent income helps you compare against lender requirements, budget more easily, and make informed decisions.
Things to keep in mind
This calculator does not include any additional fees, tax deductions, superannuation, or other adjustments — it simply converts the net amount you entered over the period into monthly and annual equivalents.
The result assumes uniform distribution of income across the time period — actual earnings may vary if you received lump-sum payments, bonuses, or had long gaps.
Always refer to the actual documentation or income statements provided by your lender, accountant or financial advisor — this tool gives a guide, not a guarantee.
FAQs about the income calculator

For simplicity, this tool is designed for a single date range and total net amount. If you have multiple payslips across different dates, you may wish to enter the earliest and latest date and sum the net amounts — or use our more advanced multi-entry estimator (if available).
Yes. The calculator is generic — you can use it for freelance income, business revenue, or any net amount over a defined period. However, if you’re using it for a loan application, ensure you follow the lender’s specific income rules which may differ.
