A guy 30s spending 50K per month will need about 2Lakh per month in the 60s for the same life style.
Better financial planning is needed.
THIS does not happen.
At 30, one need a lot of more money to buy basic needs (clothes, furniture, TVs, appliances), then comforts (2/4 wheelers, house, needs of kids....) and then luxuries. With low incomes, and more expenses, there is very little scope for savings. Loans are taken, EMIs balloon.
But, by the time you are 60, the daily/weekly/monthly expenses come down drastically - you do not buy clothes, vehicles, appliances, furniture, flats, houses.... ALL ARE ALREADY CREATED BY YOU. No outstanding loans, no EMIs, not worried about fashions or trends or fads.
Instead of assets creations, you do only asset maintenances - at a fraction of costs.
When the grown up kids are well settled n married, you will have excess assets - and start selling some - at huge profits (real estate, bullion, stocks....). Because, kids priorities will be beyond your's n they need better n more modern assets in better places.
The only expenses which increase are medical. Some spikes in gifting n travel also die down. Only health related expenses keep on increasing.
The plus point then is - returns on investments keep increasing, almost minimal sustenance n maintenance expenses and well-off n better placed kids. Generally no worries.
That's a reality for most of the lot - planned n systematic life course. Unless one screws up this with illogical n stupid decisions on the way.
