Functional Point (FP) Estimation Method is said to be independent of computer language, capability and technology used. A contractor stipulates that a computer application is to be developed according to the present data in the table below. Before the system reaches the testing stage, the customer requests some changes which resulted to the addition of 100 FPs with changes to 55 existing FPs. After the acceptance testing stage, the customer asks for changes to some of the functions in the system amounting to 200 FPs and some new functions which amount to 125 additional FPs with deletion of 60 existing FPs.

Calculate the additional charge based on the present data.

FP feature	Pre-acceptance testing handover	Post-acceptance testing handover
Cost per FP	Rs 500	Rs 800
Additional FPs	100%	120%
Changed FPs	140%	175%
