ANNUITIES- FINDING I OR N WHEN PV/FV AND PMT ARE KNOWN

WHAT IF PV AND Pmt ARE KNOWN BUT i OR n ARE UNKNOWN?

• When PV and Pmt are known, calculate TF first
• TF= PV/ Pmt. If i is given, look for n that corresponds to the TF.
• Similarly, if n is given, look for the i that corresponds to the TF.
• Do the same when FV and Pmt are known
• Examples
