Should You Quit Your Job to Start a Business?

Should you quit your job to start a business? For most people, not at first. Starting while employed lets you test demand, earn early revenue and build savings before you give up a salary. Quitting makes sense once the business has paying customers, you have a funded runway, and the job has become the main thing slowing it down.

That answer disappoints people who want permission to walk out on Monday. In the interviews I do with indie founders, the dramatic resignation story is rarer than you would think. The more common pattern is a long overlap, a few months or a few years of nights and weekends, followed by a quiet exit once the side business was already paying some bills. This page lays out what the decision depends on, the paths founders actually take, and the mistakes that make the jump harder than it needs to be.

What the decision really is

Quitting your job is often framed as the moment you become a founder. It is better understood as a financing decision. Your salary is the cheapest capital you will ever have: it pays your rent while you find out whether anyone wants what you are building. When you quit, you replace that capital with savings, a partner’s income, debt or early revenue.

That is why the question “am I brave enough?” leads people astray. The useful questions are narrower. How many months can you live without a salary? How fast is the business likely to replace it, based on evidence rather than hope? What happens to your health coverage? And does your employment contract allow you to build this at all while you are still on the payroll?

There is also a time question. Some businesses can be built in ten hours a week; others cannot. A newsletter, a small software tool or a freelance service can often grow on evenings. A restaurant, a manufacturing business or anything that needs you on site during business hours usually cannot. The nature of the business sets a ceiling on how long the overlap can last.

What the evidence says about keeping your job

The best-known study on this question is by Joseph Raffiee and Jie Feng, published in the Academy of Management Journal in 2014. They followed US workers from the National Longitudinal Survey of Youth 1979 cohort and compared two routes into full-time self-employment. People who first ran a business while keeping a paid job, and then moved to full time, had a 33.3% lower hazard of exiting self-employment than people who went straight from a paid job into full-time entrepreneurship. The longer people stayed in the hybrid phase, the lower their exit hazard.

The same study found that more risk-averse people were less likely to jump straight into full-time self-employment, but their risk aversion did not stop them from starting a hybrid business. In other words, the hybrid path appears to give a way in to people who might hesitate to make a full jump.

Read this carefully. It does not prove that keeping your job causes a business to survive. People who start part time may also choose safer ideas or learn more before committing. What it does show is that the hybrid route is not a timid compromise. It is a common and well-documented way in, and in that study the people who took it lasted longer.

For context on the stakes, the US Bureau of Labor Statistics reported that of private sector establishments born in March 2013, 79.6% were still operating a year later, and 34.7% were still operating ten years later. Any plan to leave a job should assume the first version of the business may not be the one that works.

What the decision depends on

Five factors carry most of the weight. None of them is about how motivated you feel.

Factor	Points toward staying for now	Points toward leaving
Revenue	No paying customers yet	Revenue is growing and covers a meaningful share of your personal costs
Runway	Under a few months of expenses saved	Savings cover your personal budget, business costs and insurance for your chosen runway
Time the business needs	Can grow on 10 to 15 hours a week	Customers, partners or operations need you during working hours
Contract	IP assignment, moonlighting or non-compete terms that cover your idea	Clean contract, or written permission from your employer
Household	Dependents relying on your income and coverage, no second earner	A partner’s income or coverage, low fixed costs

The revenue line matters most. Leaving to find out whether people will pay is far more expensive than finding out while you still have a salary. Validation can happen on evenings and weekends; that is what the next milestone, how to validate a business idea, is about.

The common paths

Founders tend to leave their jobs in one of five ways. Each has a different risk profile, and the right one depends on the factors above.

1. Build on the side, then leave

This is the hybrid route described in the research. You keep the job, build in your own time and set conditions for leaving. Its strengths are obvious: income, health coverage and time to learn. Its weaknesses are fatigue, slower progress, and the risk that the overlap drifts on for years without a decision. It works best when the conditions for leaving are written down in advance. Our guide to starting a business while working full time covers how to do it without burning out or breaching your contract.

2. Cut back before you cut loose

Some founders negotiate a four-day week, a part-time role or a move to contract work for their employer. This buys hours without giving up all income. It depends on an employer willing to agree and on a role that can be done part time, so it is not available to everyone.

3. Save a runway, then leave

Others decide the business cannot grow on evenings, so they save hard for a fixed period and then quit with a defined number of months of savings. This is a reasonable choice for businesses that need full attention from day one. The risk is that savings start a clock, and the clock creates pressure to accept bad customers or bad deals. The size of that runway is the subject of how much money to save before starting a business.

4. Leave with your first client

Service businesses often start this way: a consultant or freelancer leaves with one or two contracts already signed. This is one of the safest jumps, but check your contract before you do it. Taking your employer’s clients or using confidential information can create legal trouble that outlasts the business.

5. Quit first and figure it out

Some founders do leave with no product, no customers and a modest cushion. In the stories I hear, some of them make it work and others end up taking another job, which is not a disaster but is an expensive way to learn something that could have been tested on the side. If you choose this path, do it with your eyes open and a hard date for reassessing.

Health insurance and taxes in the US

For US founders, two costs often surprise people who have only ever been employees.

The first is health insurance. According to KFF’s 2025 Employer Health Benefits Survey, the average annual premium for single coverage at work was $9,325, of which the average worker paid $1,440; the employer covered the rest. When you leave, that employer share becomes your cost. Leaving a job for any reason, including quitting, qualifies you for a Special Enrollment Period on the federal Marketplace, and HealthCare.gov says you should apply within 60 days of losing job-based coverage. COBRA lets you keep your old plan, usually for 18 months, but the US Department of Labor explains that the premium can include both the employee and employer shares plus 2%.

The second is tax. The IRS sets the self-employment tax rate at 15.3% (12.4% for Social Security and 2.9% for Medicare), and you may need to pay estimated taxes quarterly. As an employee, part of this was paid by your employer; as a founder, you pay it yourself.

Neither cost is a reason not to start. Both are reasons to calculate your number properly before you hand in your notice.

The mistakes founders make most often

These patterns come up again and again in founder stories. None of them is fatal on its own, but they compound.

• Quitting to validate. Leaving before anyone has paid is the most expensive form of market research available. Pre-sales, pilots and paid trials can all happen while employed.
• Counting only startup costs. Many first businesses cost little to launch. What runs out is the founder’s personal money: rent, food, insurance and taxes.
• Ignoring the contract. IP assignment and moonlighting clauses can give your employer a claim on work you did on your own time, depending on the contract and the state. Read it before you build, not after.
• No exit criteria. The hybrid path fails quietly when “I will quit when it feels right” becomes five years of nights and weekends. Set revenue, savings and date thresholds.
• Burning out before leaving. Running a job and a business at once is hard. Founders who skip sleep for a year often arrive at the moment of quitting already exhausted. Our piece on founder burnout covers the warning signs.
• Treating it as permanent. Going back to a job is not failure. Founders I talk to sometimes return to employment between ventures, and planning for that possibility makes the jump less frightening and the decision clearer.

A simple test before you resign

Before you resign, answer these questions in writing. If you cannot answer one, that is the work to do next.

1. How much does the business earn per month now, and how has that changed over the last three months?
2. What is your total monthly personal budget, including health insurance and taxes you do not pay today?
3. How many months can you cover with savings, and what will you do when that number reaches three?
4. What would the business do with the extra 30 to 40 hours a week that it cannot do now?
5. Have you read your employment contract, and does anything in it cover what you are building?
6. Who depends on your income, and have you discussed the plan with them?

Question four is the one people skip. If you cannot name what the extra hours would produce, more customers, a launch, a sales process, then quitting will give you time but not progress.

The supporting guides for this milestone

Two articles go deeper into the practical side of this decision.

• Starting a Business While Working Full Time covers the hybrid path: how founders find the time and energy, what to check in your employment contract (moonlighting clauses, IP assignment, non-competes), how to avoid conflicts of interest, and the signals that the business is ready for you full time.
• How Much Money to Save Before Starting a Business gives a method for calculating your number, combining personal runway, startup costs, US health insurance and taxes, with a worked example.

How to know you are ready for the next milestone

You do not have to have quit to move on. The next step on the route is validation, and it works just as well while you are employed. You are ready for it when you have chosen whether you will build on the side or leave, you know your contract allows the work, and you have a written number for your runway and a date or threshold for revisiting the decision.

If you have already left, the same applies in reverse: get to validation fast, because every month without evidence is a month of runway spent.

Where this sits on the route

This is milestone three, the last step of the Decide phase. Before it comes How to Come Up With a Business Idea, where you choose what to build. After it comes How to Validate a Business Idea, the first milestone of the Launch phase, where you find out whether anyone will pay for it.
