Workers must have an early plan that can guarantee future welfare when entering retirement age. Given the economic development and technological advances that will trigger an increase in needs, a worker will certainly not always be able to work well especially after reaching a certain age. Workers' productivity will decline and workers will enter retirement age where needs still exist and will continue to exist while after retirement workers no longer get income from their previous jobs. One solution that can be done is to join a pension fund program. This research aims to determine normal retirement bene ts, normal contributions and actuarial liabilities with the normal entry age method based on the Rayleigh distribution. The parameters in the Rayleigh distribution were estimated using maximum likelihood estimation and then Maple 13 software was used to obtain the estimation results.The solution of problem is obtained by determining the probability of death, initial life annuity temporary, bene ts, normal contributions and actuarial liabilities with the normal entry age method and then formula is obtained based on the distribution of Rayleigh. The amount of pension bene ts, normal contributions and actuarial liabilities obtained by using the normal entry age based on the Rayleigh distribution is smaller than the case study conducted at Pt.Taspen Pekanbaru branch.enNormal retiremententry age normal methodrayleigh distributionmaximum likelihoodArticle
