Business Calculators

Practical financial calculators built for Australian businesses. Use them online free — your inputs are saved in your browser, no sign-up required, and no data ever leaves your device.

People & Pay

Sales & Wages

Pay your people accurately and keep your sales team motivated. Work out tiered commission in seconds, then check a pay figure including overtime, weekend penalty rates and casual loading before it ever reaches payroll.

Borrowing, Compliance & Exit

Loans, Tax & Valuation

Know what borrowing costs, what the ATO lets you claim back, and what your business is worth. See a full amortisation schedule for any loan, build Division 40 depreciation schedules with days-held pro-rating handled automatically, and check an indicative value range for your business using industry earnings multiples before you price a sale or a buyout.

Build These Models Yourself

Every calculator here follows best-practice Excel structure. Our complete guide walks through assumptions, calculations and outputs so you can build your own versions — or we can build them for you.

These calculators are provided for information and illustrative purposes only. They are not financial advice and results are estimates that may vary based on individual circumstances. All reasonable care has been taken in their design, but you should verify any results with your accountant or financial advisor before making decisions.
