I want excel to sum the highest 5 numbers in a row of 20-25. This means it'll first need to find 5 highest values and then add 'm up.

Example:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 would be 20+19+18+17+16 = 90

Does excel allow for an easy way to do this automatically, or do I have to do this manually?

Thanks in advance
