9 strategies to save a fortune, from real people who bank half their income
9 strategies to save a fortune, from real people who bank half their income · CNBC

A lot of ordinary people have managed to save extraordinary amounts of money. Take early retirees Justin and Kaisorn McCurry, who banked more than $1 million in a decade, or "The Money Wizard," a Minneapolis-based 26-year-old who has accumulated $150,000 in savings .

They've shown us that you don't necessarily need a Wall Street salary to reach financial independence at a young age. At the McCurry's peak earning period, they were making a combined $138,000, and "The Money Wizard," who goes by the pen name Sean, started with a salary of $70,000.

You do, however, need the discipline to keep a large chunk of your paycheck, which is exactly what the McCurry's, Sean and other super-savers do.

Here are some of the best lessons we've learned from people who save at least 50% of their income.

Automate everything

In just five years, Grant Sabatier of "Millennial Money" went from having $2.26 in his bank account to $1 million. During his five-year journey to seven figures, in addition to focusing on earning, he saved 50% of his income.

The key to saving half your income, he says, is to make things automatic: "Automation is essential. When I first started saving and investing, I was a little more old school — I was trying to invest as much as possible into the online savings accounts I had set up and it was a pretty manual process. Now, one of the biggest recommendations I make is to automate as much of your savings as possible."

The reason it works is because you'll never be tempted to skimp on savings since you'll never see your money going automatically from your paycheck to your savings accounts.

Go homemade

"This one was the biggest 'aha' moment of the year for me," writes Matt of "Distilled Dollar," a Chicago-based CPA who saves 60 percent of his income with his fiancee and plans to be financially independent by age 35.

Matt estimates that they save about $5,000 a year by going out less. "Not only did we start to cook more, but we found creative ways to save money at the grocery store," he says. "Plus, we are eating much healthier now, too."

Focus on cutting the "big three expenses"

Keep the "big three expenses" — housing , transportation and food — as low as possible, says early retiree Justin McCurry . "Look at those top expenses and see if there's any negotiating room." Doing so helped him and his wife save up to 70% of their income and build a $1 million portfolio in a decade.
