each month I will add a number - I want to create a formula that will add the numbers in column b and multiply it by 1.5 until it reaches 1,000,000. Then when this number exceeds 1,000,000 multiply the excess over 1,000,000 by 1.65 and add that to what the product was from 1 - 1,000,000. Then when the total becomes greater than 1,400,000 multiply that excess over 1.4M by 1.8 and add that.

summarize 1-1M * 1.5
1.1M - 1.4M * 1.65
1.41M - and greater * 1.8

I need a miracle!

IF January starts in A1 the first input number in cell B1 then cell C1 would have:

=IF(B1>1410000,B1*1.8,IF(B1>1100000,B1*1.65,IF(B1>0,B1*1.5,"")))

C2:
=IF(B1+B2>1410000,B2*1.8,IF(B1+B2>1100000,B2*1.65,IF(B1+B2>0,B2*1.5,"")))

C3:
=IF(SUM(B1:B3)>1410000,B3*1.8,IF(SUM(B1:B3)>1100000,B3*1.65,IF(SUM(B1:B3)>0,B3*1.5,"")))

C4:
=IF(SUM(B1:B4)>1410000,B4*1.8,IF(SUM(B1:B4)>1100000,B4*1.65,IF(SUM(B1:B4)>0,B4*1.5,"")))

C5:
=IF(SUM(B1:B5)>1410000,B5*1.8,IF(SUM(B1:B5)>1100000,B5*1.65,IF(SUM(B1:B5)>0,B5*1.5,"")))

C6:
=IF(SUM(B1:B6)>1410000,B6*1.8,IF(SUM(B1:B6)>1100000,B6*1.65,IF(SUM(B1:B6)>0,B6*1.5,"")))

C7:
=IF(SUM(B1:B7)>1410000,B7*1.8,IF(SUM(B1:B7)>1100000,B7*1.65,IF(SUM(B1:B7)>0,B7*1.5,"")))

C8:
=IF(SUM(B1:B8)>1410000,B8*1.8,IF(SUM(B1:B8)>1100000,B8*1.65,IF(SUM(B1:B8)>0,B8*1.5,"")))

C9:
=IF(SUM(B1:B9)>1410000,B9*1.8,IF(SUM(B1:B9)>1100000,B9*1.65,IF(SUM(B1:B9)>0,B9*1.5,"")))

C10:
=IF(SUM(B1:B10)>1410000,B10*1.8,IF(SUM(B1:B10)>1100000,B10*1.65,IF(SUM(B1:B10)>0,B10*1.5,"")))

C11:
=IF(SUM(B1:B11)>1410000,B11*1.8,IF(SUM(B1:B11)>1100000,B11*1.65,IF(SUM(B1:B11)>0,B11*1.5,"")))

C12:
=IF(SUM(B1:B12)>1410000,B12*1.8,IF(SUM(B1:B12)>1100000,B12*1.65,IF(SUM(B1:B12)>0,B12*1.5,"")))

Thanks

I haven't checked whether or not the formula works, but assuming it does, it is not necessary to have 12 different formulas. Just put the following in C1 and drag it down :-

=IF(SUM(\$B\$1:B1)>1410000,B1*1.8,IF(SUM(\$B\$1:B1)>1100000,B1*1.65,IF(SUM(\$B\$1:B1)>0,B1*1.5,"")))

Lars --

What should be the result(s) if we have the following entries?

{"Jan",150000;
"Feb",200000;
"Mar",650000;
"Apr",100000;
"May",350000;
"Jun","";
