I am tring to create a formula that will provide the same output as Excel's Rate function. Havent been abe to find anything online or in the forum. Any help is greatly appreciated!

Example from Excel:  =RATE(120,-468.67,27483,,0)*12
This formula produces a value of 16.48%
 

Term Months	120
Monthly Loan Payment	468.67
Financed Amount	27,483.00
