Two numbers give you a first answer. Adding expenses and self-employment tax gives you the real one, and the gap between them is usually larger than expected.

Replacing salary is not the same as matching it: you also give up employer benefits, and revenue is far less predictable than a paycheque.

The simple version
$70,000 a year is $5,833 a month. At $25 a month that is 234 customers. This is the number worth having in your head — it is far more concrete than "build a SaaS".
| Your price | Customers | Realistic? |
|---|---|---|
| $10/mo | 584 | Needs a large audience |
| $25/mo | 234 | Achievable for a focused niche |
| $50/mo | 117 | Very achievable for B2B |
| $99/mo | 59 | Fifty-nine relationships |
| $199/mo | 30 | Thirty customers |
Thirty customers at $199 is a fundamentally different undertaking from 584 at $10 — for the same income.
Why the honest number is higher
- Self-employment tax. In the US that is roughly 15.3% on top of income tax, which an employer previously split with you.
- Health insurance. Often the largest single line for a US founder leaving employment.
- Business expenses. Hosting, tools, accounting — small individually, real in aggregate.
- Volatility. A salary arrives every month. MRR does not have to.
The step most people actually take
Going from full-time employment to full-time founder in one move is rare. The common path is to reach half the number, drop to four days a week or contracting, and use the freed time to reach the rest.
Halving the target also halves how long it takes to reach — and the second half is usually faster than the first, because you have more time to work on it.
GOOD QUESTIONS
Frequently asked
Should I include tax in the calculation?+
Yes, if you want the honest number. In the US self-employment tax is about 15.3% on top of income tax, covering the portion an employer used to pay. Leaving it out understates the requirement by roughly a sixth.
How much runway should I have before quitting?+
Most advice lands at six to twelve months of personal expenses in cash, on top of hitting the revenue target. MRR can fall, and having to take contract work to cover rent is what usually kills momentum.
Is it better to go part-time first?+
Usually. Reaching half the target and dropping to four days or contracting reduces the risk substantially, and the extra day a week compounds — the second half of the target typically arrives faster than the first.
Does the number change with churn?+
Yes. At 5% monthly churn on 234 customers you lose about 12 a month, so you need 12 new customers monthly just to hold the line. Build the treadmill into your plan, not just the target.
