2. Perpetuity is a type of
Annuity.
Annuity is a continuous
stream of payments made at
equal intervals for a specific
amount of time
3. Example
500$
0 1 2 3 4 5
500$ 500$ 500$ 500$
When stream of payments continues forever
or for indefinite amount => perpetuity
infinity
500$
4. The perpetuity value
is infinite , but the
present value is
LIMITED
The value of 500$
after 99 years with a
rate of 10% is0.04$
5. ,So the present value of our previous example for
infinite continuous payment is 500/0.1= 5000$
