SuperFVCalc is a comprehensive app designed to save you time by providing over 20 formulas in one place. This iPhone application falls under the Business & Productivity category, specifically in the Finance subcategory. It offers a range of features to help you calculate future values and annuities accurately.

With the Future Value Compound/Simple Interest calculator, you can easily calculate the future value (FV) using the present value (PV), interest rate, and number of periods. Likewise, you can calculate the present value (PV), interest rate, or number of periods based on the given FV.

The app also includes calculators for Ordinary Annuity Future Value, Annuity Due Future Value, Ordinary Annuity Present Value, and Annuity Due Present Value. These calculators allow you to determine the future value (FV), payment per period, rate, or number of periods based on the provided variables.

SuperFVCalc comes with several advantages. It automatically formats numbers for easier readability and allows for easy percentage entry. Instead of typing in 0.05 for 5%, you can simply enter "5". Additionally, the app eliminates the need to refer to an Annuity Table to find interest rates, as it performs accurate iterations to instantly calculate the interest rate.

Overall, SuperFVCalc is a valuable tool for anyone involved in financial calculations, offering convenience, accuracy, and time-saving features.
