Performing Annuity Calculations
To perform an annuity calculation, you must
know any four of the five values (N, % i, PV,
PMT, or FV). Follow these steps to find the
unknown value:
1. Press 0 b to clear the registers, and
use 2 to enter the financial mode (FIN
appears in the display).
2. Ensure that the calculator is set correctly for
the type of annuity calculation desired.
§ For ordinary annuities, Begin should not
be displayed.
§ For annuities due, Begin should be
displayed.
Press 0 a to turn Begin on or off.
3. Enter the four known values (N, % i, PV,
PMT, or FV).
4. Press 1 and the key for the unknown
value.
Note: Generally, solving for the interest rate
requires more time than other calculations. If
you use unrealistic values, the calculator may
take several minutes before indicating an error
condition. If this occurs, press u to clear
the calculation.
