Help with Weighted Average

[Kim]

Can someone please help me to find a way round my problem. Here is a sample of


A B C D E
Product City Price Room night
H1 ROME 100.00 15
H2 LONDON 105.00 100
H3 ROME 203.00 5
H4 ROME 150.00 115
H5 LONDON 200.00 5

This is what I need.
On Column E I need the weighted average price for H1 based on room night.

Thanks.

Hi David,

Thanks.

But I need to have the average based on the same city.

Regards,
Kim

Maybe...

=SUMPRODUCT(--(b2:b6="Rome"),C2:C6,D26)/SUMif(b2:b6,"rome",D26)

 

[David Biddulph]

=SUMPRODUCT(C$2:C$6,D$2$6,--(B$2:B$6=B2))/SUMIF(B$2:B$6,B2,D$2$6)

than 50 cities. So what's the best way ?
