Hi Guys

Need your help. 

I want to put a formula in the attached sample worksheet as per below requirement.

In the first month of purchase, the value will remain the same, after this, it will depreciate by 30% i.e. the book value will be 70%.

Please help me. The file is attached.

 

Regards

 

Ali

Hi Ali,

I assume you want the depreciation data to continue to the end of the year

If so, then only one formula needed:
clear cells F3:Q5 and type this into cell F3

=IF(F2:Q2<C3:C5,,B3:B5*(1-D3:D5)^DATEDIF(C3:C5,F2:Q2,"m"))

that should then spill across and down to complete your data

 

Furthermore, if you define the date series as a spilling formula (eg =DATE(2021,SEQUENCE(,12),1), then you can use this in the above formula too:

=IF(F2#<C3:C5,,B3:B5*(1-D3:D5)^DATEDIF(C3:C5,F2#,"m"))

or slightly less elegantly:

=IFERROR(B3:B5*(1-D3:D5)^DATEDIF(C3:C5,F2#,"m"),)

then, if you extend your date series (by changing the 12 to the desired no of months), your data formula will also extend itself to match

sometimes Excel is just magic!
