Average Calculator: Find the Mean of Four Values
Calculate the arithmetic mean of up to four numbers. This is the most common type of average — the sum of all values divided by the count. Useful for grades, measurements, ratings, and any set of numbers you need to summarize.
Formula
Average = (a + b + c + d) ÷ 4. Enter any four numbers; the calculator sums them and divides by 4. If you enter fewer than four values, leave the rest as zero or enter the same value multiple times.
Worked example
Scores of 85, 90, 78, and 92: sum = 345, average = 345 ÷ 4 = 86.25.
Practical guidance
When to use the arithmetic mean
Use this average for test scores, product ratings, temperature readings, or any data where all values contribute equally. The mean is sensitive to outliers — one very high or low number can shift the result significantly.
Handling missing values
If you only have 2 or 3 values, enter 0 for the remaining inputs or duplicate an existing value. The calculator always divides by 4, so be intentional about how you handle empty slots.
