This paper analyze the impact of effort calculated using various membership functions and measure mean square error for software effort estimation. Eight membership functions available in fuzzy logic are used and a comparison is made to find out which membership function yields better result in terms of Magnitude Relative Error (MRE), Mean Magnitude of Relative Error (MMRE). Inaccurate software cost estimation has plagued software projects for decades. Poor estimates have not only led some

Therefore, an accurate software effort and cost estimation is highly required in software project management. The result will show the best suited membership function for calculating effort.
