Solving for Yield 

Solving for yield is essentially the same as solving for Internal Rate of Return (

IRR

). 

The keystrokes are as follows: 

1. Press 

f

CLEAR

H

. 

2.  Key in the amount of the first cash flow then press 

gJ

. This initial amount 

is the difference between the initial loan amount and any payments received 
at closing time. Observe the sign convention: positive for cash received and 
negative for cash paid out. 

3.  Key in the amount of the first cash flow then press 

gK

. Then key in the 

number of times that cash flow occurs then press 

ga

. 

4.  Key in 0

gK

 then the number of advance payments minus one. Then 

press 

ga

. 

5.  Key in the residual then press 

gK

. Then press 

fL

 to solve for 

periodic yield. 

Example:

 Equipment worth $5,000 is leased for 36 months at $145 per month. 

The lessee has agreed to pay the first and last month’s payments in advance. At 
the end of the lease, the equipment may be purchased for $1,500. What is the 
annual yield to the lessor if the equipment is purchased

?
