Try this out your monthly investment could be as low as $25 and you're return could be as big as you build it just take a look do some research on it whatever this is a foolproof way of making a great monthly salary I'm to the point that I really don't even need my day job anymore.

Go see an independent financial advisor or specifically a retirement advisor for advice on your problem.

I don't have a clue where you are based. It sounds as if your father needs to buy an annuity to pay a weekly/monthly pension. This is somewhat complex - so needs an expert's advice.

Hate to tell you this, but return and risk go hand in hand.

My father has got some good amount after retirement from govt job and want to invest it so that he will get a good return every month and the principal money will be safe even after 20 years.amount is around Rs 5000000
