In the paper, Euler gives a general formula for calculating the price of a life annuity that yields a certain amount per year, assuming the annuity manager can get a 5 percent return, for people of different ages. He also gives formulas to calculate the price of annuities that only start to pay out a certain number of years after they are purchased. He gives many numerical examples, giving tables for the prices of annuities for annuitants up to 90 years old.9 pages, English translation of ``Sur les rentes viageres'', Memoires de l'academie des sciences de Berlin 16 (1767), 165-175History and OverviewProbability01A50; 91B30text
