The order in which you're prompted for values depends upon the variable you're solving for.

SOLVE instructions:

1.If your first TVM calculation is to solve for interest rate, I, press

I.

2.Press . If necessary, press ×or Øto scroll through the equation list until you come to the TVM equation.

3.Do one of the following five operations:

a.Press Nto calculate the number of compounding periods.

b.Press Ito calculate periodic interest.

For monthly payments, the result returned for I is the monthly interest rate, i; press 12 to see the annual interest rate.

c.Press B to calculate initial balance of a loan or savings account.

d.Press Pto calculate periodic payment.

e.Press Fto calculate future value or balance of a loan.

4.Key in the values of the four known variables as they are prompted for; press

after each value.

5.When you press the last , the value of the unknown variable is calculated and displayed.

6.To calculate a new variable, or recalculate the same variable using different data, go back to step 2.

SOLVE works effectively in this application without initial guesses.
