The interest rate is the only value you can calculate in this worksheet.
It is automatically recalculated if you change C1, C2, or C3. However,
you can backsolve for the other values (investment, term, or future
value) by using Solve 1-2-3 on the Calculator.
Example:
Changing the Interest Rate and Backsolving for the
Future Value.
Enter the worksheet shown above, then calculate what the maturity
value would be if this $10,000, 5-year bond yielded 12% annual
interest (1% monthly interest). Remember to enter a percentage rate
as a decimalfraction (that is, 0.01 for 1%).
For the worksheet:
m The cell format for C1 and C3 is set by /Range Format Currency 0.
The cell format for cell C5 is set by /Range Format Percent 2.
m The formula for cell C5 is @RATE(C3,C1,C2).
m Cell C1 contains the investment value $10,000 and cell C2 contains
the term 60 months.
m Enter a future value of $18,000 in cell C3, and the monthly interest
rate of 0.98% (11.76% annually) is automatically calculated.
Change the interest rate and backsolve for the future value:
