(current_age >= retirement_age) ? 0 : ( (current_balance * Math.pow(1 + (annual_growth_rate / 100 / 12), (retirement_age - current_age) * 12)) + (monthly_contribution * ((Math.pow(1 + (annual_growth_rate / 100 / 12), (retirement_age - current_age) * 12) - 1) / (annual_growth_rate / 100 / 12)))) * ((annual_withdrawal_rate / 100 / 12) / (1 - Math.pow(1 + (annual_withdrawal_rate / 100 / 12), - (pension_payout_years * 12))))
