The worth of money in future depends on where it lies today. For example, if you keep Rs. 10,000 in your pocket or piggy bank, it’s worth 20 years later will be the same as Rs. 4,563 today (assuming inflation rate of 4% p.a.). However, if it is invested in an investment that earns 8% p.a. interest the same amount will be Rs. 46,600, worth Rs. 21,272 in today’s terms. You can use the investment calculator to estimate the answers quickly on your terms.
