The present value of a perpetuity can be calculated by taking the limit of the above formula as n approaches infinity. =. Formula (2) can also be found by subtracting from (1) the present value of a perpetuity delayed n periods, or directly by summing the present value of the payments
Because the interest will not vest until her new child reaches 25 years of age, which cannot happen until more than 21 years after A and her other children (together who form the "lives in being" to which the rule refers) have all died, the rule against perpetuities makes the entire gift "to the first of A's children to reach 25 years of age" void.
Assuming that payments begin at the end of the current period, the price of a perpetuity is simply the coupon amount over the appropriate discount rate or yield; that is, = where PV = present value of the perpetuity, A = the amount of the periodic payment, and r = yield, discount rate or interest rate.

The denominator of a Rule of 78s loan is the sum of the integers between 1 and n, inclusive, where n is the number of payments. For a twelve-month loan, the sum of numbers from 1 to 12 is 78 (1 + 2 + 3 + . . . +12 = 78). For a 24-month loan, the denominator is 300. The sum of the numbers from 1 to n is given by the equation n * (n+1) / 2.
1. Estimate the bond value The coupons will be $50 in years 1, 2, 3 and 4. Then, on year 5, the bond will pay coupon and principal, for a total of $1050. Discounting to present value at 6.5%, the bond value is $937.66. The detail is the following: Year 1: $50 / (1 + 6.5%) ^ 1 = 46.95 Year 2: $50 / (1 + 6.5%) ^ 2 = 44.08
Therefore, the future value of your annuity due with $1,000 annual payments at a 5 percent interest rate for five years would be about $5,801.91.
Similarly, we can prove the formula for the future value. The payment made at the end of the last year would accumulate no interest and the payment made at the end of the first year would accumulate interest for a total of (n − 1) years. Therefore,
Perhaps that’s a fixed period, such as 20 years, or perhaps it’s for the remainder of the client’s life. So the annuity can offer the certainty of income and the possibility of never ...
