If you need to sum numbers based on multiple criteria, you can use the SUMIFS function.
In the example shown, the formula in G8 is:
How this formula works
The first range (D4:D11) are the cells to sum, called the “sum range”.
Criteria are supplied in pairs…(range / criteria).
The first criteria pair is (B4:B11 / “green”). This means cells in B4:B11 must equal “green”.
The second criteria pair is (C4:C11 / “>15”). Cells in C4:C11 must *also* be > 15.
These cells in the sum range will only be summed when all criteria pass.
