The milestones and what they buy
$1,000 MRR covers your infrastructure and proves strangers will pay; it is ramen-adjacent, not a salary. $5,000 MRR is quit-your-job territory in most of the US once you account for self-employment tax and $400 to $700 per month in health insurance, though not in San Francisco or New York. $10,000 MRR is a comfortable solo income, roughly equivalent to a $100k to $120k salary after the tax differences. $20,000 plus MRR puts you in the top decile of solo founders and usually means real distribution, not a launch spike.
How long it takes when it works
Solo founders who reach $5,000 to $10,000 MRR typically take 12 to 24 months, often with one or two failed products before the one that worked. The first $1,000 is frequently the slowest stretch, commonly 6 to 12 months of iterating on positioning and channels. Growth is lumpy, not linear: months of flat followed by a jump when a channel clicks. If you are at $0 after 12 months of real distribution effort, the honest read is usually the market, not your effort.
The survivorship bias warning
The founders posting MRR screenshots are the winners; most solo SaaS projects never cross $1,000 MRR and shut down quietly. Indie hackers who publish their numbers are a self-selected sample from the top few percent. That does not mean the path is fake, it means the base rate is worse than your feed suggests. Plan your runway around the median outcome, not the screenshots.
What matters more than the headline number
MRR with 10 percent monthly churn is a leaky bucket, not a business; $5,000 MRR at 2 percent churn is worth more than $8,000 at 9 percent. Net MRR growth after churn is the number to watch every month. Concentration matters too: $5,000 from 150 customers is far safer than $5,000 from 3. Judge progress on retained, diversified recurring revenue, not the vanity total.
