Hi,

I would like to know if there are joint and survival annuity functions in pyliferisk.

Thanks in advance.

Hi, Gustavo.

Try annuity() function (see section "2.3 Annuity formula" in documentation". Example:

Premium calculation: A Life Temporal insurance for a male, 30 years-old and a horizon of 10 years, fixed annual premium (GKM95, interest 6%):

import pyliferisk as lf
from pyliferisk.mortalitytables import GKM95

nt = lf.Actuarial(nt=GKM95, i=0.06)
x = 30
n = 10
C = 1000

print(C * (lf.Axn(nt, x, n) / lf.annuity(nt, x, n, 0)))

In case of whole-life annuity use x=nt.w

Kind regards,

F.
