Formula to compute for values if cells have values less than a specified amount

Formula

=SUMIF(range, expression)

Add the values in cells if the value is greater than 3000

=SUMIF(A1:A8,"<3000")

Add the values in cells if the value is greater than 1000

=SUMIF(A1:A8,"<1000")

Add the values in cells if the value is greater than 500

=SUMIF(A1:A8,"<500")

Formula Parameters

• Range – The first part of the formula lets you specify the range to add. This is specified like this, A1:A20
• Expression – The second part of the formula lets you specify the condition. The condition is in string form. You can use multiple logical operators like <, =, <=, >=

=SUMIF(A1:A8,"<=2000")

=SUMIF(A1:A8,">=2000")

=SUMIF(A1:A8,"=2000")

Formula to compute for values if cells have values greater than a specified amount

Formula

=SUMIF(range, expression)

=SUMIF(A1:A8,">4000")

Add the values in cells if the value is greater than 2000

=SUMIF(A1:A8,">2000")

Add the values in cells if the value is greater than 1000

=SUMIF(A1:A8,">1000")

Formula Parameters

• Range – The first part of the formula lets you specify the range to add.
• Expression – The second part of the formula lets you specify the condition. The condition is in string form. You can use multiple logical operators.
