Calculating monthly totals

[Guest]

Does anyone know the best formula for adding figures in a column that
correspond to each month of the year?

I have a sales register with the date of sale and commission on each row but
want to display the total commissions for each month of the current year on
one worksheet and monthly totals for previous year on athother worksheet.

Any ideas would be greatly appreciated.

Thanks
Simon

Hi

To return summary commissions for January of current year
=SUMPRODUCT(--(MONTH(SaleDate)=1,--(YEAR(SaleDate)=YEAR(TODAY()),Commission)

The same for last year
=SUMPRODUCT(--(MONTH(SaleDate)=1,--(YEAR(SaleDate)=YEAR(TODAY()-1),Commissio
n)

Thanks Arvi, does SaleDate have to be replaced by the month required or is
that the column title?

Many thanks

Hi

SaleDate and Commission are ranges, where sale dates and commission figures
are stored. You can use there range references or named ranges. NB. Both
ranges SaleDates and Commission MUST be of same dimension.

When SalaDate doesn't contain valid format dates, then you have to modify
the formula - how, depends on your data then.

Avri, thanks for explaining that.

I have entered the following formula for the current year:
=SUMPRODUCT("--(MONTH(Websites!B5:B31)=01,--(YEAR(Websites!B5:B31)=YEAR(TODAY()),Websites!R5:R31)")
but I just get #VALUE! in the cell where the monthly commission total should
be displayed.

Have you any ideas why this is?

Thanks
Simon

Hi

=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1),--(YEAR(Websites!B5:B31)=YEAR(TODAY
())),Websites!R5:R31)

I have entered this formula:
=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1),--(YEAR(Websites!B5:B31)=YEAR(TODAY())),Websites!R5:R31).
But I still get a popup error message that says: 'The formula you typed
contains an error'.

Thanks

Hi

To locate the part of formula, causing the error, try to calculate different
parts of formula

=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1))
=SUMPRODUCT(--(YEAR(Websites!B5:B31)=YEAR(TODAY())))
=SUMPRODUCT(Websites!R5:R31)
=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1),--(YEAR(Websites!B5:B31)=YEAR(TODAY
())))
etc.

I have tried all the parts of the formula and the only one that causes the
error is:

=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1),--(YEAR(Websites!B5:B31)=YEAR(TODAY())))

All these worked fine:
=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1))
=SUMPRODUCT(--(YEAR(Websites!B5:B31)=YEAR(TODAY())))
=SUMPRODUCT(Websites!R5:R31)

Any idea where the error is located?

Many thanks

Hi

I tried to det the same error with same formula, and all partial formulas
working properly - I get it only, when referred ranges were different
dimensions. Something like
=SUMPRODUCT(--(MONTH(Websites!B5:B31)=1),--(YEAR(Websites!B5:B131)=YEAR(TODA
Y())))

So check, that all referred ranges contain cells from 22 rows, and all of
them are single-column ranges.

Yes, thanks, it works fine now. Still not quite sure where the error was but
all is OK now thanks to you.

Much appreciated
