Prepaid Expense amortization

I have an example. Maybe you can check if this is working out.

If it doesn’t work out, enter manually and drag.

Thanks, but this equation calculate according to month. I actually want if start date is on Jan 15 Calculate the remaining 16 days only, after Jan Feb 28 days and so on.

I tried this formula =IFS(AND(G1<$B2,G1<$C2),SUM(DAYS(EOMONTH($B2,0),$B2)*$F2),AND(G1>$B2,G1<$C2),(EOMONTH(G1,0))*$F$2) but this one only calculate the first month only.

That is great that you could work it out. Did you try to drag it to the right to auto fill? This is as much as I know. 

Yeah, I tried but it only read the first condition. Anyway thanks for your kind reply. Still working on it to sort out.
