How many sales calls do I need to hit my revenue goal?
Divide your monthly goal by your price to get customers, then divide back through each stage: close rate, show rate, inquiry-to-call rate and visit-to-inquiry rate. Pipeline Math, a free tool from InstinctGTM, does it for one-off or recurring revenue and shows which rate moves your numbers most.

How this works
- 1Customers needed each month is the goal divided by the price. For recurring revenue it is the growth still needed spread over the months you choose, plus the revenue churn takes away each month.
- 2Calls held is customers divided by close rate. Calls booked is calls held divided by show rate.
- 3Inquiries, anybody who replied, filled a form or signed up, is calls booked divided by the inquiry-to-call rate. Visits is inquiries divided by the visit-to-inquiry rate.
- 4Every stage is rounded up, because half a customer is one more conversation. Weekly numbers are the monthly ones spread over 52 weeks a year.
- 5"What moves the most" raises each rate by 5 points and sorts them by how many visits it saves.
The rules, in full
Rules version 1, published 2026-10-28. Every number is a InstinctGTM starting rule, never an industry benchmark.
| Rate | Starting assumption | Used when |
|---|---|---|
| Visits to inquiries (a reply, a form, a sign-up) | 2% | I don’t know |
| Inquiries to booked calls | 25% | I don’t know |
| Show rate (calls booked to calls held) | 80% | I don’t know |
| Close rate (calls held to customers) | 20% | I don’t know |
| Customers lost each month | 3% | I don’t know, every month |
| Months to get there | 12 | I don’t know, every month |

A worked example
Example numbers
10 calls held and 2,308 visits a week
10 sales a month at $1,000. At a 25% close rate that is 40 calls held, 50 booked, 200 inquiries and 10,000 visits a month, with the other three rates left as starting assumptions.
What it cannot tell you
- Rates you do not know are filled with starting assumptions, labelled as such. Your own numbers from the last few months beat them.
- It assumes every stage converts in the same month. A long sales cycle means the calls you book now close later.
- Recurring revenue uses one churn rate on the whole goal, which overstates churn while you are small.
Questions people ask
How many inquiries do I need to hit my revenue goal?
Work backwards from the goal: divide it by your price for customers, then by your close rate, show rate and inquiry-to-call rate. A $10,000 monthly goal at $1,000 a sale with a 20% close rate needs 50 calls held, before no-shows.
How many sales calls do I need to hit $10K MRR?
Divide the new revenue you need each month by the monthly price for new customers, add the revenue churn removes, and divide by your close rate. At $100 a month you need 100 customers to reach $10K, so the calls depend on how fast you want to get there.
What is reverse funnel math?
Planning from the goal back to the top of the funnel: revenue to customers, customers to calls, calls to inquiries, inquiries to visits. It turns a revenue target into a weekly activity number somebody can act on.
Which conversion rate should I improve first?
The one that saves the most work at the top of the funnel for the same improvement. A few points on close rate usually saves more visits than the same points on visit-to-inquiry, because every stage above it shrinks too.
What if I do not know my conversion rates?
Press "I don’t know" and a starting assumption is used and labelled. Replace it with your own number once you have a month of data, because an assumption is a guess about somebody else’s business.
The short version, if you would rather not run it
A revenue goal on its own is a wish. Worked back through the funnel it becomes a weekly number: so many calls held, so many booked, so many people raising a hand, so many visits. That number is the one you can do something about on a Monday.
The other thing the math shows is where effort pays. Improving close rate by a few points shrinks every stage above it, so it often saves more work than any amount of extra traffic.
