My take on this is that if you are under 30 and making 1.4M a year and can foresee a 25% + inflation rate increase every year on average, with a retirement nest egg of 500T now and increasing also by 25% + inflation rate, dyan ka na lang.
Or kahit lower yung retirement... basta make sure you'll have enough by 55 or 60... ok ka na. Unless magastos ka... in which case, you will need more.
