App Annuity Calculator

he app is designed to calculate an annuity table. The application works in three modes: - defines future accumulation and present input; - determines the deposit; - determines how many times (time) it is imported / towed.
In all modes, a two-part table is calculated, one for future accumulation and the other for current withdrawal. In the first case, a regular sum is paid and accumulated amount is determined by the deadline. In the second case, the one-time calculated amount shall be paid and shall be withdrawn regularly until it is exhausted to the deadline.
The periodic interest is calculated by dividing the annual interest rate by the number of payments per year.
              Future value is determined by the formula FV = R ((1 + i) ^ n-1) / i, and the Present value is determined by the formula PV = R (1- (1 + i) ^ (- n)) / i.
where i is the interest for the payment period, R is the deposit and n is the number of payments.
The"Copy DB” for print" feature copies the database to Phone storage on the device and its name is Annuity.db and its table is annuityservice. Further, to print the data, the table must be exported. To do this, use a browser for SQLite databases to download from the Google store on tablets and mobile phones or PCs from http://sourceforge.net/projects/sqlitebrowser/. The exported spreadsheet has a .csv extension and opens and prints with Open Office to use a ";" (semicolon) for the column separator.
