Cash Flow Budget Calculator
These two budgets are linked, simple to navigate and both have a number of in-built features that allow businesses to more accurately forecast profitability and cash flow. The cash flow budget automatically calculates the GST by prompting users to select either monthly or quarterly GST reporting and whether GST is paid on either a cash or accrual basis. Also, the collection and payment percentage rates for debtors and creditors (e.g. current, 30 days, etc) can be entered to better reflect the impact of sales and purchases on the cash flow position.

Property CGT Calculator
This unique calculator provides an indicative comparison of the capital gain derived on the sale of a commercial or investment property by a resident individual and also the additional tax payable on the gain under both the Indexation and 50% Discount Methods. Also included are Notes to guide investors on the various items that may form part of the cost base of the property and the adjustments that may need to be made to the cost base upon sale.

Monthly Hire Purchase Amortisation Calculator
This calculator produces a schedule displaying the monthly breakdown of payments between principal and interest for assets financed under a hire purchase contract.
