This is financial calculator software for performing what-if scenario analysis. PowerOne Finance starts by converting the functionality of advanced financial calculators into calculation templates. Then it adds the power to install or create additional templates that match your needs. Finally, powerOne Finance connects this data to other applications so you can share your calculations with clients and colleagues. Customize to any industry and any set of special calculations by downloading from Infinity's Web site or writing your own.
