# Find date from target %

Hi,

I have a set of values for dates and corresponding %s

1-Jan-18 8%
1-Feb-18 6%
1-Mar-18 8%

I need a single cell formula to find the particular date at which a target cumulative % is achieved

For Eg, the target cumulative % of 20% will be achieved on 22-Feb-18

For Eg, the target cumulative % of 20% will be achieved on 22-Feb-18
I do not understand how cumulative can exceed 20% before March (unless there is already a cumulative value of approx 8% at 31-Dec-17)
The method is correct, but my table exceeds 20% on 26 March

I would create a table with a cumulative value for EVERY day and look up the value in that table with a simple formula in the cell
- dates must be sequential earlier to later for this formula to work

=INDEX(A:A,MATCH(0.2,D:D,1)+1)
