Methodology

Conventions

  • Mortality follows Makeham's law μ_x = A + B c^x (the SOA Standard Ultimate Life Table uses A = 0.00022, B = 2.7×10⁻⁶, c = 1.124), or your own table of q_x.
  • Within a year of age, a table assumes a uniform distribution of deaths. The table ends at age 120.

Formulas

Survival under Makeham
{}_tp_x = \exp\!\Big(-A t - \frac{B c^x (c^t - 1)}{\ln c}\Big)
Mortality rate
q_x = 1 - p_x,\quad d_x = l_x q_x
Curtate expectation
e_x = \sum_{k \ge 1} {}_kp_x
Complete expectation
\mathring{e}_x = \int_0^\infty {}_tp_x\,dt \approx e_x + \tfrac12
