Hello,

I am working on a forecasting model and have run into some trouble when trying to extend the X-Axis of a 12-month Curve Distribution to a longer time frame. Given a distribution of 12 percentages (one for each month), how can I spread the 12 months or periods to say 18 months while maintaining the integrity of the curve.

Example:

Distribution Amount$1,000,000
Known Curve123456789101112
Bell Curve1.00%3.00%6.00%8.00%12.00%20.00%20.00%12.00%8.00%6.00%3.00%1.00%
Spend Pattern 10,000 30,000 60,000 80,000 120,000 200,000 200,000 120,000 80,000 60,000 30,000 10,000
Adjusted Curve123456789101112131415161718

How to calculate loan payments in Excel?
Use the PMT function: =PMT(5%/12,60,-25000) is for a $25,000 loan, 5% annual interest, 60 month loan.
I don't know how to find the pattern exactly but here's a rough guess:
