• Andre Nader built a seven-figure portfolio by saving and investing in index funds.
• He leveraged his tech career and dual-income household to maximize savings and investments.
• One strategy he used to max out tax-advantaged accounts is known as ‘a mega backdoor Roth’.

Andre Nader built a seven-figure portfolio before age 40 by following a few simple fundamentals: save a chunk of your income, invest it in low-cost index funds, and max out tax-advantaged accounts.

It helped that he worked in tech. He said he started with a modest $40,000 salary right after graduating, but eventually landed a high-paying job at Meta in 2014.

“I won the income game by being in tech, by being a dual-income household,” Nader, whose wife is a designer at Uber, told Business Insider.

When he got laid off in 2023, he and his wife had enough between her tech income and their savings that he didn’t have to find another job. Nader, who’d been writing about financial independence on his blog FAANG FIRE since 2021, now writes on Substack full-time and does one-on-one FIRE (financial independence, retire early) coaching.

As a high-earner who describes himself as “naturally frugal,” Nader found himself with excess savings each month. When he was working full-time, he and his wife used one of their incomes for household expenses and saved the other.

He spent a lot of time thinking about, “How do I save this in the most efficient way possible?” he said. “And, for many in tech, it’s going to be about taking advantage of those tax-advantaged accounts. Because when you’re in those extremely high earning years, any amount that you can defer those taxes into the future is potentially extremely, extremely valuable.”

One particular tax-advantaged account, a Roth IRA, offers major benefits, including tax-free growth — but there’s an income limit that can prevent individuals like Nader from contributing directly to it. In 2024, single tax filers must make less than $146,000 to contribute to a Roth, and married couples filing jointly must make less than $230,000.

Nader has used a workaround known as a mega backdoor to sidestep the Roth IRA income limit, and he recommends all high-earners take advantage of it if they can.

Using a mega backdoor Roth to contribute up to $69,000 a year into his 401(k)

To understand how a mega backdoor Roth works, it’s important to first understand how after-tax 401(k) contributions work. Some employers offer an after-tax 401(k) — Nader had access to one when he was at Meta, and his wife has one at Uber — which allows you to save more after you’ve maxed out your traditional 401(k).

In 2024, the annual contribution limit for a 401(k) is $23,000 for employee contributions; but the combined employee and employer contribution limit is $69,000. Say you max out your 401(k) and contribute $23,000, and your employer contributes $5,000 through the matching program, so you have $28,000 in your 401(k). Since the limit is $69,000, if your plan allows for after-tax contributions, you can put another $41,000 in after-tax dollars into the account.

In Nader’s wife’s case, Uber matches up to $8,000, so after maxing out her 401(k) in 2024, she’ll make an additional $38,000 after-tax contribution ($69,000 – $23,000 – $8,000), he explained.

The catch is, while sitting in the after-tax state, any earnings you make on those contributions are taxable.

That’s where the mega backdoor Roth comes into play. It allows you to shift after-tax 401(k) contributions to a Roth IRA or Roth 401(k), where it can grow tax-free. Not all 401(k) plans allow this conversion and you’ll want to understand your plan, including its restrictions, before making any after-tax contributions.

In Nader’s experience, executing the mega backdoor Roth when he was working at Meta was quick and easy. He logged into Fidelity NetBenefits (his 401(k) provider) and elected the percentage of his after-tax earnings he wanted to contribute. Then, he was able to do an in-plan conversion and selected the option to “convert after-tax contributions.”

“Every single time I post about it on LinkedIn, someone doesn’t know that they had this benefit,” said Nader, who has nearly 25,000 LinkedIn followers and specifically writes for FAANG (Facebook, Amazon, Apple, Netflix, and Google) employees looking to achieve financial independence. “This extra $30,000, effectively, can end up in a Roth 401(k) — and that’s a super powerful type of account.”

He recognizes that not everyone has access to this strategy, nor has the funds to save $69,000 a year in a 401(k). But if you’re a high-earner who would be saving that money anyway and your plan allows a mega backdoor Roth, “it’s really valuable for them to be aware that exists.”
