Deductions & credits

I was going through the formula and realized FMV at time of death was not (obviously) included. Would I add the cost basis as of 2019 to step up basis to get the DOD value? 

 

For example:

  price of home 30k

   + cost to buy - 2k (etimating real estate fees at time)

 + improvements thru 2019 - 100k (estimate)

= cost basis as of 2019- $132k

Would i then add FMV at time of death (~450k from zillow/redfin) to the cost basis (132k) to get DOD value (582k)?
