What MRR Should You Hit Before Quitting Your Day Job for Your SaaS?
The "quit your job" number is different for every founder. Here is a framework for calculating yours honestly — accounting for burn rate, churn risk, and personal runway.
There is no universal MRR number that means you are ready to quit your day job. A founder in Bangalore with $800 a month in expenses has a completely different threshold than a founder in London with a mortgage and dependents. The question is not "what is the magic number?" — it is "what is my number, and am I being honest about it?"
The minimum viable salary calculation
Start with your actual monthly expenses: rent, food, utilities, insurance, any debt payments, and the things you would not cut even in a financial emergency. Add 20% as a buffer for the unexpected expenses that will arrive in the first year of full-time founding. That total is your floor — the MRR you need just to survive without any growth.
Example: £3,000 a month in expenses + 20% buffer = £3,600. But your MRR is gross revenue — you need to subtract hosting, tools, taxes, payment processing fees, and any other cost of running the business. If your margin is 70%, you need £5,140 in MRR to net £3,600. That is your survival threshold, not your comfort threshold.
Why 2x is the right multiplier
Most advisors suggest quitting when your MRR reaches 2x your monthly expenses. The reasoning: your first year of full-time building will likely be the period of highest churn risk, slowest growth, and highest unplanned costs. You need a buffer not just for month one but for month eight, when you have spent eight months full-time and growth is slower than you projected.
A founder who quits at 1x survival threshold and encounters a 20% churn month (which happens — a pricing experiment goes wrong, a key integration breaks, a competitor launches a free tier) is suddenly at 0.8x and in financial stress. Financial stress makes product decisions worse. Buffer matters.
The churn rate adjustment
If your monthly churn rate is above 5%, do not quit until that is fixed. High churn means the MRR you have today is not the MRR you will have in three months. Quitting your job into a leaky bucket is a fast path to having neither the job nor the business.
Fix churn first. Leaving a job for a business with 8% monthly churn and no clear fix is betting your financial stability on a problem you have not solved. Extend your timeline, keep the day job, and fix the retention before you make the leap.
Factors that change the threshold
| Factor | Adjust threshold |
|---|---|
| Partner income covers expenses | Lower — you can afford more risk |
| Dependents (children, family) | Higher — more financial responsibility |
| High monthly churn (>5%) | Higher — revenue is not stable |
| Proven acquisition channel | Lower — you know how to grow |
| No acquisition channel yet | Higher — revenue growth uncertain |
| Low-cost location | Lower — threshold is smaller in absolute terms |
| Health insurance dependency (US) | Higher — add full cost to monthly burn |
The time cost argument for quitting earlier
There is a real case for quitting before you are "ready." Working on a side project in two to four hours a week is not the same as working on it full time. Many founders find that going full time produces a step change in growth — not because they worked harder but because they could think more deeply, move faster, and talk to customers without scheduling calls around a day job.
If you have six months of living expenses saved and a product with real traction, quitting before your MRR fully covers your expenses is a rational bet. Just be honest about what six months of runway actually looks like if growth stalls.
The alternative: reduce your day job first
Negotiating to four days a week before quitting entirely gives you 20% more time at 20% less income. For founders close to the threshold, this is often the most rational step — lower the financial risk while increasing the growth rate. Many employers will accommodate a reduced schedule for a good employee rather than lose them entirely.
