How much money should you have saved for retirement at every age?

A Moneycontrol report said a person investing ₹10,000 per month in their 20s can see the amount grow significantly over 30–35 years due to compounding. It suggests having two to three times annual income invested by 35 and four to five times by 40. By 45, the target should be six to eight times, and by 50, eight to tenfold.
