Examples
For example, an Interest rates module has the Contracts list on columns and line items on rows. The module shows different loan amounts and monthly payments for two customer contracts.
The formula in the Monthly interest rate line item calculates the periodic interest rate for each contract.
Contract 1  Contract 2  
Loan amount  $5,000  $7,500 
Monthly payment  $95.00  $135.00 
Number of periods  60  60 
Monthly interest rate
 0.440039%  0.255868% 
In this example, the formula in the Annual interest rate line item calculates the yearly interest rate for each contract.
Contract 1  Contract 2  
Loan amount  $5,000  $7,500 
Monthly payment  $95.00  $135.00 
Number of periods  60  60 
Annual interest rate
 5.28047%  3.07042% 
In this example, the formula calculates the required interest rates for two investments to return a future value.
Contract 1  Contract 2  
Number of periods  12  36 
Payments  0  0 
Current value  $5,000  $7,500 
Future value  $15,000  $25,000
