Following is the logic for dependent needs.
Annual Expenses + Annual Insurance Premium of all other members of the family. We exclude premiums of policies that you ask client to surrender.
If expense is 0 then we consider income * 70%. If income is also 0 then we consider Rs.2,40,000 per year.
PV = PMT * ( ( 1 - ( ( 1 + r ) ^ - n ) ) / r )
r = Inflation adjusted Return (Inflation Adjusted Return = ((1+Expected Return On Investment)/(1+Expected Inflation))-1)
n = Dependent Living Years
PMT = Adjusted Annual expenses
