We find the actuarial premium of the continuous type using actuarial present value of life annuity and life insurance. In this processes, we also use the force of interest and the force of mortality also. We start the finding of the actuarial premium of the discrete type using actuarial present value of life annuity and life insurance. We have some insight from the discrete type and develop the idea to the continuous type. We give some examples of UDD(Uniform Distribution of Death) and simple distribution of death to extract such idea. Finally we give the excel program to handle such examples. We also compare the formulas of the premium of the continuous type with those of discrete type. Finally we find the formula of benefit reserve of the continuous type.
