Find out how to evaluate and choose the best double your money scheme

Looking to double your money in a short time

Setting goals are a significant aspect of personal finance. How to earn money post-retirement and take care of emergencies and aspirations is a concern shared by most people.

But, with many options, from money double schemes and tax exemption schemes to mutual funds and stocks, it is a daunting task to choose the right one.

How to Evaluate Savings Schemes?

A simple formula, termed the thumb rule of 72, gives you an idea of your investment's time to double. Divide 72 by the interest rate of your proposed investment. To illustrate, consider the interest rate of 6.8%; therefore, 72 / 6.8 will give you 10.58. The result indicates that you can double your money in about ten and half years in that particular investment scheme.

Conversely, the formula also gives you the interest rate required for the number of years to double your investment. For example, if your money doubling target is five years, divide 72 by 5. The result 14.4 indicate a saving instrument with a minimum 14.4% rate of return.

Which scheme to invest in?
