| Clinic booking ads | ₹15,000 | 30 bookings | ₹500 |

Frequently Asked Questions
How do you calculate CPA?
CPA = total cost ÷ number of conversions. For example, ₹20,000 spent for 50 leads is a CPA of ₹400.
What is the difference between CPA and CPL?
CPL (cost per lead) is a type of CPA where the conversion is a lead. CPA can also mean cost per sale, booking or sign-up.
What is a good CPA?
Any CPA that is lower than the profit a customer brings you. Work out customer value first, then set your target CPA.
How do I find cost per customer from cost per lead?
Divide CPA by your closing rate. If each lead costs ₹400 and 1 in 4 leads buys, each customer costs ₹1,600.
Is CPA the same as CPC?
No. CPC is the cost of a click; CPA is the cost of a result. Many clicks may be needed for one conversion.
