The question “how much should we spend on marketing?” rarely gets a useful answer. Generic advice like “spend 10% of revenue” ignores the fact that a ₹50 lakh business and a ₹5 crore business have completely different competitive situations, margins, and growth objectives. This framework gives you a more honest, practical way to think about your marketing budget.
Start with the Economics, Not the Percentage
The right way to think about a marketing budget: what is it worth to you to acquire one new customer? Work backwards from that number.
Example: A dental clinic where an average new patient is worth ₹8,000 in their first year, and 60% return for repeat treatments (adding another ₹5,000 on average), making lifetime value approximately ₹13,000. If you are willing to spend 15% of lifetime value to acquire a customer, you can afford ₹1,950 per new patient.
If your current cost per lead is ₹300 and your lead-to-patient conversion rate is 25%, your cost to acquire a patient is ₹1,200 — well within your acceptable number. Your marketing budget is correctly sized if it is generating profitable acquisitions at scale.
Budget by Business Stage
Starting Out (Revenue under ₹25 lakh/year)
Minimum viable marketing budget: ₹8,000-₹15,000 per month. Focus entirely on one channel — Google Ads for immediate leads OR local SEO for free traffic. Not both simultaneously; concentrate enough budget on one to make it work properly before adding a second.
Growing (₹25 lakh – ₹1 crore/year)
Marketing budget: 8-15% of revenue, approximately ₹15,000-₹50,000 per month. Run Google Ads and Meta simultaneously with proper tracking. Begin investing in SEO content and Google Maps optimisation. This is the stage where the combined system starts generating compounding returns.
Established and Scaling (₹1 crore+ revenue)
Marketing budget: 10-20% of revenue, ₹80,000-₹2,00,000+ per month. Full-funnel marketing across Google, Meta, SEO, content, and email/WhatsApp automation. Agency-managed with detailed ROAS targets by channel.
What to Cut When Budget Is Tight
When budget needs to be reduced, cut in this order: first, reduce spending on the channel with the highest cost per lead. Never cut below the minimum threshold for any remaining channel — an underfunded campaign delivers disproportionately poor results. Better to be strong on one channel than weak on three.
Before scaling your marketing spend, verify you have: accurate conversion tracking (you know your real cost per lead and cost per customer), a profitable unit economics model (your cost to acquire a customer is less than their lifetime value), and a scalable process for handling more leads. Pouring more budget into a broken system makes the problem more expensive, not more successful.
