What if more leads closed?

Closing 20% more of the same leads would turn 8.0 customers into 9.6 and make profit ₹7,600, on the same spend.

At these numbers the spend is not paying back yet. Better targeting, a faster follow-up or a clearer offer usually helps most.

Frequently asked questions

What is cost per lead?

Cost per lead is your marketing spend divided by the number of leads or enquiries it produced. It tells you what each enquiry costs.

What is customer acquisition cost?

Customer acquisition cost (CAC) is your marketing spend divided by the number of new customers it produced. Compare it with the profit a customer brings to see whether the spend is worth it.

What is ROAS?

Return on ad spend is revenue divided by marketing spend. A ROAS of 3× means every rupee spent produced three rupees of revenue, before the cost of delivering the sale.

Why include profit margin?

Revenue is not profit. A sale costs money to deliver, so the calculator subtracts it to show whether the spend actually paid back.
