How many customers does your MRR target need?
Divide your target MRR by your monthly price and round up — that's the number of paying customers you must win and keep every month. At $9/month, a $10K target means 1,112 customers; at $99/month it's 102. This one division kills more solo ideas than any competitor does: low-ticket pricing quietly demands consumer-scale distribution.
You need 205 paying customers at $49/month to reach $10,000 MRR.
How to read the number
- Under ~150 customers — reachable with content + communities for a niche B2B tool. This is the solo sweet spot.
- 150–1,000 — you need a repeatable acquisition channel, not just launches. Most solo founders underestimate this tier.
- 1,000+ — consumer-scale distribution at a solo budget. Raise the price or change the buyer; volume won't save a $5/month product.
Churn makes it worse: at 5% monthly churn, holding 200 customers means replacing ~10 every month before you grow at all.
Is my SaaS too support-heavy to run solo?
Run the two calculators together. Price decides how many customers your target needs; support minutes decide how many one person can carry. An example, at 15 support minutes per customer a month and a $10,000 monthly revenue target:
- At $29 a month you need 345 customers, which is 19.9 hours of support a week: heavy. Support is the job.
- At $99 a month you need 102, which is 5.9 hours a week: moderate.
At 15 minutes each, one person carries about 139 customers before support passes 8 hours a week. If your target needs more than that, raise the price, cut the minutes with self-serve onboarding, or pick a different buyer. The longer versions: will my SaaS be support-heavy? and how many customers you need.
