At a 45% close rate you clear break-even by 14 points. Calls priced up to $146 still pay back.
Estimates only. Your per-call rate is confirmed for your industry and service area before you fund an account, and results depend on how quickly and how well calls are answered.
How the calculator works.
Every number on this page comes from five inputs. Here is exactly what it does with them.
New customers
Calls per month multiplied by your close rate.
Revenue and gross profit
New customers times average revenue, then times your gross margin.
Net contribution and ROI
Gross profit minus call spend. ROI is that result divided by call spend.
Break-even guardrails
The close rate where gross profit equals spend, and the highest per-call price that still nets zero at your close rate.
Calculator questions.
How do I calculate ROI on pay-per-call?
Multiply calls by your close rate to get new customers, multiply by your average revenue per customer to get revenue, apply your gross margin, then subtract what you paid for the calls. Divide the result by the call spend for ROI.
What is a break-even close rate?
The share of calls you must close so gross profit equals call spend. It is the price per call divided by revenue per customer times gross margin. If your real close rate is above it, every call makes money.
What is the most I should pay per call?
Your close rate times revenue per customer times gross margin. Any price below that number is profitable at your current performance. Faster answer times and better phone skills raise it.
Are the default numbers real?
The per-call ranges are our published rates. The ticket sizes, close rates, and margins are conservative industry starting points, and you should replace them with your own.
Why does answer rate matter so much?
Calls you do not answer during your posted hours can still be billable, and a missed caller usually books elsewhere. Every point of answer rate lifts your effective close rate and your ROI.
