Cost Spreading Calculator

This is a simple online cost spreading calculator that can be used to spread the estimated cost of a program up to 8 years. The calculator uses a beta curve to determine the amount of money to be spent in each year based on the fraction of the total time that has elapsed. The user enters the total cost to be spread, the beginning and ending years.

There are two parameters that determine the shape of the spending curve. The cost fraction is the fraction of total cost to be spent when 50% of the time is completed. The peakedness fraction determines the maximum annual cost.
