"How many clients do I need to live from my business?" Almost every coach and consultant asks the question — and almost all answer it with a guess: "about ten, I think." That isn't a number, it's a worry. And a worry without a number produces two behaviours: accepting any client, and undercharging.
The answer fits in three numbers you already know: the price of your programme, its duration, and the monthly revenue you're aiming for. The calculator below does the rest — number of clients active at the same time, new clients to sign each month, and discovery calls to hold to get there. Then we look at what those numbers say about your offer, because that's where most plans change.

Three scenarios for 5,000 € a month
The same goal, three different offers. Look at the last column: that's what decides your life.
| Offer | Price | Duration | Revenue per client per month | Clients active at once | New clients per month | Calls per month (1 signature in 3) |
|---|---|---|---|---|---|---|
| Single sessions | 150 € | — | 150 € per session | 34 sessions a month | 34 | ~100 |
| Short programme | 1,500 € | 2 months | 750 € | 7 | 3.5 | ~11 |
| Structured programme | 3,000 € | 3 months | 1,000 € | 5 | 1.7 | ~5 |
| Long journey | 6,000 € | 6 months | 1,000 € | 5 | 0.8 | ~3 |
Three readings:
Revenue per client per month is the number that counts, not the price. 3,000 € over three months and 6,000 € over six months bring in the same each month — but the second needs half as many signatures.
The number of active clients tells you your load: five clients at once is sustainable alone; thirty-four sessions a month is a full practice that leaves no room to sell.
Calls per month tell you your sales effort: three to five calls a month is one conversation a week; a hundred is impossible without a team.
What the calculation says about your offer
If your result shows more than ten new clients a month, your problem isn't prospecting. It's the offer: too short, too cheap, or sold by the unit. No acquisition method sustains a pace of thirty monthly signatures for an independent.
Two levers change everything, and they don't require more skill:
Lengthen. A three-to-six-month programme rather than a standalone workshop: same expertise, one signature instead of three, and revenue that doesn't restart from zero every month. The small-contracts guide explains the switch.
Raise the price. Between 1,500 and 3,500 €, you attract price-sensitive buyers and multiply sales cycles. Reframing the offer as a result and targeting people for whom the amount is marginal divides the number of clients needed by two or three. The pricing guide details the method.
Redo the calculation with a 4,500 € offer over four months: for 5,000 € a month, you need a little over one new client a month, and three or four calls. It's a different job.
What the calculation says about your pipeline
The number of calls is a weekly target, not a monthly one: five calls a month is one or two a week, every week. And a call doesn't fall from the sky — it comes from a conversation, which comes from a contact.
Trace the chain back: for one call, how many conversations opened? For one conversation, how many messages or pieces of content? Those ratios are yours, and you only know them by measuring. To start, a working rule: three conversations for one call, three calls for one signature. It improves fast with qualification before the call and a structured call.
And if you don't have an audience, that's not a problem: the system for finding clients without an audience starts from exactly these three numbers.
The three calculation mistakes
- Counting revenue, not income. Out of 5,000 € collected, there are still charges, tools, taxes. Aim for the revenue that leaves you the income you want — not the income itself.
- Forgetting selling time. A programme with ten hours of delivery also demands the hours of prospecting, calls, follow-up. The more clients to sign, the bigger that share grows — until it eats the delivery.
- Confusing peak and pace. Three signatures in your launch month don't make three signatures a month. The calculation is done on the pace you can sustain twelve months in a row, not on the best month.
The calculation on one page
Price ÷ duration = revenue per client per month → target ÷ that revenue = clients active at once → active clients ÷ duration = new clients per month → × calls per signature = calls per month → more than ten new clients a month: it's the offer to change, not the prospecting → lengthen, raise the price, recalculate.
Want to do this calculation with someone, on your real offer? Book a 45-minute call: we start from the numbers you entered above, and you leave with the offer — price, duration, target — that makes your goal reachable.
