As it can be seen, the payments dominating the principal
sum are greater for years 6 to10 when compared to the first through the fifth years
(negative indicates payment).
[10 ΣInt (] : Calculates the sum of interest dominating the payment sum.
Input method: ΣInt (Initial number of payments, end number of payments, displayed
number of decimals).
The displayed number of decimals is optional.
<Example 10>
We will compare the sum of the interest dominating the payment sum after 5 years and
10 years, as with example 9.

* Calculations cannot be executed for [08 Bal(], [09 ΣPrn(] and [10 ΣInt(] if the known variables of
example 1 are not entered.
(for execution of calculation, numerical values must be entered to I%, PV and PMT)
[11 →Apr (] : Converts effective interest rate to nominal interest rate.
Input method: →Apr (effective interest rate, number of settlements)
<Example 11>
How much is the nominal interest rate for the quarterly compound interest (every three
months) when the effective interest rate is 12.55%? What
would the nominal interest rate be when monthly com-
pound interest rate is 10.5%? (TAB setting is 2).
