Divide a value by months remaining between two dates

Greeting's, pardon me for what I'm certain is a minuscule question. I'm not an avid Excel user. I have just started and I mean literally just . I did try searching for this but I got answers (and formula's) that didn't quite fit my query.

I have a cell where an amount is displayed. I need a formula (or method) to divide this amount by remaining months between today to 28th February, 2016. Mind you, i need the division by month and not days. Goal of this is to find number of day's remaining to achieve an investment value I've set for myself.

For example: cell has value of 100 (investment target) and i need to find remaining months i have to achieve that value (remaining months will be from today till 28th February, 2016). The remaining months value has to be dynamically updated too.

Thank you in advance.

I am using Microsoft Excel 2013.

For those you are searching for an answer. I found this to be useful:

(reference cell/(DATEDIF(DATEVALUE("01-03-2015"),DATEVALUE("29-2-2016"),"m")+1))*(DATEDIF(DATEVALUE("01-03-2015"),TODAY(),"m")+1)

I am at times confused about how many months I need to use, but that's due to my exhaustion and unfamiliarity with excel.

Thank you!

Thank you actually
