The Full Form of PIG is Passive Income Generator.

Passive income is defined as income that requires minimal effort—or perhaps even zero effort—to earn. Passive income typically enables your money to work for you. It’s a “work smarter, not harder” situation. We can compare it against active income, where your effort is 100% correlated to your income.

The best passive income takes the least effort. But today, we will consider many popular passive income ideas that will earn you money, whether you want to pay off a student loan, dig out of credit card debt, or put together a retirement plan. As long as it requires little passive activity, it could be a decent passive income stream.

Those who achieve financial independence will tell you that passive income streams are the key to success. The problem is that most supposed passive income ideas that you’ll find are not passive at all. A second job, for example, isn’t passive.
