## Actuarial notation

### Interest

Symbol | Meaning |
---|---|

\( i \) | The effective rate of interest, namely, the total interest earned on 1 in a year on the assumption that the actual interest (if receivable otherwise than yearly) is invested forthwith as it becomes due on the same terms as the original principal. |

\( v \) | The present value of 1 due a year hence. \( v = \frac{1}{1+i} \) |

\( d \) | The discount on i due a year hence. \( d = 1 - v \) |

\( \require{enclose} a_{\enclose{actuarial}{n}} \) | The value of an annuity-certain of \( 1 \) per annum for \( n \) years, the payments being made at the end of each year. \( \require{enclose} a_{\enclose{actuarial}{n}} = v + v^{2} + ... + v^{n} \) |

\( \require{enclose} \ddot{a}_{\enclose{actuarial}{n}} \) | The value of an annuity-certain of \( 1 \) per annum for \( n \) years, the payments being made at the beginning of each year. \( \require{enclose} \ddot{a}_{\enclose{actuarial}{n}} = 1 + v + v^{2} + ... + v^{n-1} \) |

### Mortality tables

Symbol | Meaning |
---|---|

\( p_{x} \) | The probability that (x) will live 1 year (survival). |

\( q_{x} \) | The probability that (x) will die within 1 year (mortality). |

\( {}_{n} p_{x} \) | The probability that (x) will live n years. |

\( {}_{n} q_{x} \) | The probability that (x) will die within n years. |

\( a_{x} \) | An annuity, first payment at the end of a year, to continue during the life of (x). |

\( \ddot{a}_{x} \) | An annuity-due to continue during the life of (x), the first payment to be made at once. \( \ddot{a}_{x} = 1+a_{x} \) \( \ddot{a}_{x} = \displaystyle\sum_{k=0}^{\infty} v^{k} \cdot {}_{k} p_{x} \) |

\( \require{enclose} a^{}_{x:} {}^{}_{\enclose{actuarial}{n}} \) | n-year temporary life annuity of (x) |

\( {}_{m|} a_{x} \) | m-year deferred whole life annuity of (x) |

\( A_{x} \) | whole life insurance of (x) \( A_{x} = \displaystyle\sum_{k=0}^{\infty} v^{k+1} \cdot {}_{k} p_{x} \cdot q_{x+k} \) |

\( \require{enclose} A^1_{x:} {}^{}_{\enclose{actuarial}{n}} \) | n-year term insurance of (x) |

\( \require{enclose} A^{}_{x:} {}^{1}_{\enclose{actuarial}{n}} \) | n-year pure endowment of (x) |

\( \require{enclose} A^{}_{x:} {}^{}_{\enclose{actuarial}{n}} \) | n-year endowment insurance of (x) |

\( {}_{m|} A_{x} \) | m-year deferred insurance of (x) |
