Solving for the Real Rate of Interest
(1 + inflation)
You have managed to build up your savings over the three years
following your graduation from college to a respectable P100,000
and are wondering how to invest it. Your banker says they could
pay you 5% on your account for the next year. However, you
recently saw on the news that the expected rate of inflation for
next year is 3.5%. If you are earning a 5% annual rate of return
but the prices of goods and services are rising at a rate of 3.5%,
just how much additional buying power would you gain each
year? Stated somewhat differently, what real rate interest
would you earn if you made the investment?

Determinants of Interest Rates
Problem Illustration:
Solving for the Nominal Rate of Interest
After considering a number of investment opportunities,
you have decided that you should be able to earn a real
return of 2% on your P100,000 in savings over the
coming year. If the expected rate of inflation is expected
to be 3.5% over the coming year, what nominal rate of
return must you anticipate in order to earn the 2% real
rate of return?
Nominal rate= (1 + Real rate) + (1 + Inflation rate) - 1
= Real rate + Inflation rate + ( Real rate x Inflation rate)
