'I don't hide it': This Google employee in NYC makes a six-figure salary — but lives like she's broke to make ends meet. How you can make her strategy work for you

To help herself save, Wong told MarketWatch she maximizes her tax deductions, uses credit card points when she can and automates as many financial processes as she can.

So far it's paid off: Her frugality has helped her buy her first home in New York City, pay off $47,000 in debt and book a honeymoon to Singapore and Japan.

Here are Wong's top tips for how to live like you're broke so you can live large later.

1. Save every bonus and gift

Anytime Wong gets a windfall, whether that be a bonus at work or a financial gift from friends or family, she puts it towards her student loans.

"I was very aggressive about it," she said.

If you owe a lot in student loans — or carry a hefty credit-card balance — you’ll know that interest is often what makes these debts so expensive over time. Making big (or little) extra payments, in addition to your regular monthly payments, can save you from having to pay additional interest over the long term.

And for those who are fortunate enough to be debt-free, you can apply the principle of this rule to your investing strategy. Whenever you come into a little extra cash, sock it away in your retirement account.

Keep in mind that you need not be as extreme as Wong to make this work for you. She may put aside 100% of her windfalls, but there’s nothing wrong with using some of your funds for fun. Putting aside 15% for yourself now and 85% for your future self (whether that be in clearing debt or saving for retirement) still puts you in a better financial position than before — and you might not feel so deprived either.

2. Eat cheap

Food is the third-largest expenditure for American households, accounting for 12.8% of all spending in 2022, according to the Bureau of Labor Statistics.

Wong accomplishes this by choosing the least-expensive options at restaurants: “I don’t hide it,” she said.

Instead, she'll fill up on carbs or eat beforehand, and she always checks a restaurant’s menu beforehand to ensure there’s at least one thing available within her budget.

If there's free food at work, she's ready to doggie bag it and take it home.

"There was actually a holiday party that we had once [where] I took a whole platter that ended up feeding us for a whole week," she said.
