Inflation
Inflation is the increase in the prices for goods and services from one year to
another, thus decreasing the purchasing power of money.
FC = PC (1+ f)n
Where: PC = present cost of a commodity
FC = future cost of the same commodity
f = annual inflation
n = number of years
Example 3.21: An item presently costs P1000. If Inflation is at the
rate of 8% per year. What will be the cost of the item in two years?
Solution
FC = PC ( 1+ f)n = P1000 (1 + 0.08)2 = P116.40
In an inflationary economy, the buying power of money decrease as
cost increase. Thus,
where F is the future worth, measured in today’s pesos, of a present
amount P.
Example 3.22: An economy is experiencing inflation at an annual rate of 8%. If
this continuous, what will P1000 be worth two years from now, in terms of today’s
peso?
Solution:
If interest is being compounded at the same time that inflation is occurring. The
future worth will be
