Hello, can you help me?
I have a question about how to create the result calculation for the Compound Interest Calculator with monthly contribution.
The fields created were:
1 - Value of the initial contribution ($)
2 - Monthly Contribution Amount ($)
3 - Monthly Interest Rate (%)
4 - Investment time in months
-------------------------------------------------- ------------
5 - Final total value
Note: I am not able to calculate this value.
The formula I could think of was this one but it doesn't work.
fieldname5 * pow (1 + fieldname4, fieldname3)+ (fieldname10 * pow (1 + fieldname4, fieldname3)-1)
Link to a reference calculator:
