How it works
The maths behind the budget.
Good ad budgets are worked out backwards from the result you want, not picked as a round number.
- Leads needed = customers you want ÷ lead-to-customer rate
- Monthly ad budget = leads needed × cost per lead
- Cost per customer = ad budget ÷ customers
- Revenue = customers × average customer value
- Return on ad spend = revenue ÷ ad budget
The two numbers that move the result most are your cost per lead and your lead-to-customer rate. Better creatives and landing pages lower the first; qualifying leads and following up fast raise the second. We cover both in how to lower your Meta Ads cost per lead.
This is an estimate. Real campaigns need a testing phase before costs settle, so plan for the first weeks to be about finding what works.
Questions
Meta Ads budgets, answered.
How much should I spend on Meta Ads?
Work backwards from the customers you want. Divide the customers you want by your lead-to-customer rate to get the leads you need, then multiply by your cost per lead. That's your monthly budget.
What is a good cost per lead on Meta Ads?
It depends on your industry, offer and audience. For reference, our clients have seen ₹30 per lead for an exporter and $10.61 per lead for a high-ticket program. Use your own past numbers if you have them.
What if I don't know my lead-to-customer rate?
Look at your last 20–50 enquiries and count how many became paying customers. If you have no data yet, start with a cautious estimate and update it after your first month of ads.
What is return on ad spend (ROAS)?
Revenue divided by ad spend. A ROAS of 4x means every ₹1 or $1 spent on ads brought back ₹4 or $4 in revenue.
