NumPy has a number of financial functions, as follows:
fv
function calculates the so-called future value. The future value gives the value of a financial instrument at a future date, based on certain assumptions.pv
function computes the present value. The present value is the value of an asset today.npv
function returns the net present value. The net present value is defined as the sum of all the present value cash flows.pmt
function computes the payment against loan principal plus interest.irr
function calculates the internal rate of return. The internal rate of return is the effective interested rate, which does not take into account inflation.mirr
function calculates the modified internal rate of return. The modified internal rate of return is an improved version of the internal rate of return.nper
function returns the number of periodic payments.rate
function calculates the rate of interest.
