Should Your Side Hustle Earn 2x Your Salary Before You Quit? Maybe Not.

The 2x Salary Rule: Simple, Scary, and… Overkill? #

There’s a popular rule on r/sideproject that goes like this: “Don’t quit your 9-5 job until your side hustle makes double your current salary.” Sounds clear enough, right? But here’s the thing—it’s not as cut and dry as Reddit wisdom makes it seem.

For some, doubling your salary before quitting is a blessing. For others, it’s borderline fear-mongering disguised as pragmatism. Let’s talk about the real numbers, the risks, and where this rule actually makes sense.

Wait, Why Double? Why Not Match It? #

The rule assumes two things:

Life gets more expensive once you’re self-employed.
Your side gig’s income is volatile.

Both valid points. When you’re no longer getting a steady paycheck, health insurance is on you. Vacations cost you, twice—time away from work and the money you now have to earn back. Suddenly you’re paying for software you used to expense at your job. These costs add up.

But double? That’s insurance on top of insurance. It assumes your entire business could tank and you’d still comfortably survive. Frankly, that’s overkill for most people.

The Safer Alternative: 1.25–1.5x #

Matching your salary or going slightly over is probably enough for 80% of us. For example, if you’re making $80k at your full-time gig, having your side hustle hit $100k to $120k might give you plenty of breathing room. Now, if you’re in a high-risk field (like SaaS with one major customer) or you’ve got big monthly overhead, sure—aim higher. But for a solo dev slinging Notion templates? 1.25x should work.

The Hidden Cost of Waiting Too Long #

Let’s flip the script for a second. Sticking with your day job while your side hustle is already pulling $150k+ might feel responsible, but you know what it’s really costing you? Time.

Commenter u/BuildOrRust on the thread called this out perfectly: “The opportunity cost of working your 9-5 could be killer. What’s $80k in steady salary if you’re burning profits you could scale?”

If your side hustle is already sustainable, you could focus full-time on growth. Imagine what you miss by waiting another year. While you’re clocking in at your 9-5, competitors are scaling, hiring, eating your lunch.

Quick Math: Opportunity Costs #

Let’s say your side hustle makes $100k/year while you keep the $80k job. But because your time is split, you cap growth at 10% annually. After four years:

Sticking with the job: $80k x 4 = $320k from work, plus ~$464k from your side project (compounded 10% annually). Total: $784k.
Quitting and scaling your business: $100k compounding at 30% a year could hit $585k in year four alone. Total: ~$1M, give or take.

The gap: $216k+, and we’re not even touching burnout and missed flexibility.

So When Does 2x Actually Make Sense? #

Not to hedge, but there are cases where 2x absolutely applies. Here’s when:

You’re a sole breadwinner. Got kids or a partner who’s in between jobs? You might need the cushion.
High personal expenses. Mortgage, insurance, or meds that would be catastrophic to lose if your income dropped. If you’re living leaner, you can lower the bar.
Your side hustle is erratic. Seasonal industries or one-off gig work often spike and crash. In this case, aiming for 2x can offset your “bad months.”

One commenter, u/DataWonk420, summed it up: “It depends how much risk tolerance your personal situation allows. I don’t care about 2x because I have no kids and live in a van. My expenses are $1,500/mo.” Contrast that with someone running a business and trying to pay for two college tuitions—wildly different stakes.

Final Take: Use the Rule, Don’t Worship It #

The 2x rule is a tool, not gospel. It’s there to help you think critically about risk. But clinging to it without nuance can hold you back. Better to run the numbers on your own situation—expenses, runway, growth potential—than blindly aim for 2x because Reddit said so.

FAQ #

Is it really safe to quit at 1x my salary? #

Depends. If your expenses are lean and your side hustle income is steady, 1x (or 1.25x) might be enough. But if you’ve got major monthly costs or income variability, more cushion keeps you sane.

How do I know when to quit? #

Track your side hustle numbers like a hawk. Profit margins, runway, churn rate if you’re in SaaS. Once your profits are consistent and you’ve saved 6–12 months of living expenses, you’re probably ready.

What’s the biggest mistake people make when quitting? #

Waiting too long because they’re scared or quitting too early because they’re impatient. Folks who jump before their income is reliable often underestimate costs like healthcare, new tools, and taxes. Better to test your hustle for 6 months of sustained profitability before making the leap.
