About this calculator
The ENEM Factor Calculator computes the weighted average of your five scores in the Brazilian National High School Exam (ENEM), considering specific weights for each knowledge area. Unlike a simple average, this tool allows you to assign different importance to areas such as Languages, Mathematics, Natural Sciences, Humanities, and Essay, according to each institution's or selection program's criteria.
The calculation uses the formula: factor = Σ(scoreᵢ × weightᵢ) / Σweightᵢ. You enter the five scores and their respective weights (values from 0 to 5, for example). The calculator multiplies each score by its weight, sums these products, and divides by the sum of weights. The result is a single number representing your weighted score, used by many selection processes like SISU, PROUNI, and entrance exams.
Use this calculator when you need to simulate your final score in programs that adopt differentiated weights, such as courses that value Mathematics or Essay more heavily. For instance, if a university assigns weight 3 to Essay and weight 1 to other areas, the tool automatically adjusts the average. It is also useful for comparing different weight combinations and planning study strategies.
Caution: verify that the weights entered are correct according to the selection process's official notice. Remember that the final score may vary by institution. The calculator does not consider regional bonuses or affirmative action policies, only the basic weighted average. Make sure to use official ENEM scores (0 to 1000) and consistent integer or decimal weights.
Frequently asked questions
How can I get the weights to use in the calculator?
Weights are set by each institution or program (SISU, PROUNI, FIES, entrance exams). Check the official notice of the desired selection process for the weights of each area.
Does the calculator work with decimal scores?
Yes, it accepts decimal scores (e.g., 750.5). Make sure to use the dot as the decimal separator.
What is the difference between this weighted average and the simple ENEM average?
The simple average adds all scores and divides by 5. The weighted average multiplies each score by a weight, giving more importance to some areas, as required by each course or institution.
Can I use weights with values other than 0 to 5?
Yes, you can use any positive value, but common weights range from 0 to 5. If a weight is zero, that score is not considered in the calculation.
