APP INSTRUCTIONS

The FA Pro Calculator has been designed to support CFA revision and broader financial analysis from your device. The app was developed, tested and now used daily within investment banks and CFA students world wide.  


The Calculator provides traditional and scientific functions alongside financial worksheets:

  • Time Value of Money - Analyzes equal cash flows, for example, annuities, loans, mortgages, leases, and savings.

  • Amortisation- Performs amortization calculations and generates an amortisation schedule.

  • Cash Flow - Analyzes unequal cash flows by calculating net present value and internal rate of return over 32 cash flows.

  • Bonds - Computes bond price and yield to maturity or call.

  • Depreciation - Generates a depreciation schedule using one of six depreciation methods.

  • Statistics - Analyses statistics on one or two variable data using four regression analysis options.

  • Percentage Change/Compound Interest - Computes percent change, compound interest, and cost- sell markup.

  • Interest Conversion - Converts interest rates between nominal rate (or annual percentage rate) and annual effective rate.

  • Dates - Computes number of days between two dates, or date/day of the week a specified number of days is from a given date.

  • Profit Margin - Computes cost, selling price, and profit margin.

  • Breakeven - Analyzes relationship between fixed cost, variable cost, price, profit, and quantity.

The calculator has an easily accessible Memory function.
