The following table summarizes those functions:
Function
Input format
sp.fv() fin.fv() fv(rate, nper, pmt, pv, when='end')
sp.pv() fin.pv() pv(rate, nper, pmt, fv=0.0, when='end')
sp.pmt() fin.pmt() pmt(rate, nper, pv, fv=0, when='end')
sp.npv() fin.npv() npv(rate, values)
sp.rate() fin.rate() rate(nper, pmt, pv, fv, when='end',
guess=0.1, tol=1e-06, maxiter=100)
sp.nper() fin.nper() nper(rate, pmt, pv, fv=0, when='end')
sp.irr() fin.irr() irr(values)
sp.mirr() fin.mirr() mirr(values, finance_rate, reinvest_rate)
sp.ipmt() fin.ipmt() ipmt(rate, per, nper, pv, fv=0.0,
when='end')
sp.ppmt() fin.ppmt() ppmt(rate, per, nper, pv, fv=0.0,
when='end')
