FV The future value of an investment.
PMT The periodic payment of an amortized loan or a split

CPT Compute key.
BGN Indicates whether the calculations include the payments
made at the beginning or at the end of each period.
Note:
By convention, the prent value of an investment is a negative value. The calculator is programmed this way; therefore, in calculations of future values or per-period payments, if the prent value is entered as a negative value, the future value or the value of the payments will be positive. The opposite is also true. It is therefore important to be thorough and refer to the calculator’s ur guide, if necessary.
Sample calculation of the future value (FV) of a single payment
