# Annualizing Data in a Formula

**Question**

I am creating ratios and several of them require me to annualize the numerator. For example, in the month of May, take Net Income for January through May, divide by 5, and multiply by 12 to get the projected annual income. Each month, you would add another month, thus June would be Net Income for January through June divided by 6 and multiplied by 12, etc. Can I write a formula to do this in Adaptive?

**Answer**

You should create an assumption to represent the month. For example, it would look something like this:

You would then create a formula to calculate the projected amount. The code of the account where we are writing the projection formula is called Sample.

`if(month(this)=1, div(ACCT.Net_Income, ASSUM.Month)*12, div(ACCT.Net_Income+ACCT.Sample[time=this-1], ASSUM.Month)*12)`
