"How much should I spend on marketing?" is one of those questions where the honest answer — "it depends" — sounds like a dodge. So let me give you something better: a way to actually calculate your number, instead of copying someone else's.
The businesses that waste the most money are the ones that picked a budget emotionally. They heard a competitor spends two lakh a month, or they had a good month and decided to "invest more in marketing," with no connection between the figure and what a customer is actually worth to them.
Why there's no magic number
A jewellery brand with 60% margins and a real estate developer selling ₹80-lakh flats cannot use the same marketing budget logic. One can afford to spend thousands to acquire a customer; the other operates on thin margins where every rupee of acquisition cost matters enormously.
So any article that gives you a flat "spend ₹X per month" figure is guessing. The right number comes from your own economics — specifically, what a customer is worth and how fast you want to grow.
Start with what a customer is worth
Before you decide what to spend, you need one number: the lifetime value of a customer — how much profit an average customer generates over the whole time they buy from you.
This single number sets the ceiling on everything. A business that doesn't know its customer value is flying blind — it has no way to judge whether ₹800 per lead is a bargain or a disaster.
A quick way to estimate it
- Average order value: What does a typical customer spend per purchase?
- Purchase frequency: How many times do they buy in a year?
- Customer lifespan: How many years does an average customer stay?
- Margin: What percentage of that revenue is actual profit?
Multiply those together and you have a rough lifetime value. Even a rough figure transforms your budgeting from guesswork into arithmetic.
The percentage-of-revenue method
Once you understand customer value, the simplest budgeting approach is to set marketing spend as a percentage of revenue. It scales naturally — as you grow, your budget grows with you.
These are starting points, not rules. A new business with no existing revenue obviously can't budget as a percentage of zero — which brings us to budgeting by stage.
Realistic budgets by business stage
Pre-revenue or just launched
You're budgeting from savings or investment, not revenue. The goal here isn't profit — it's learning. Spend enough on one channel to find out whether your offer converts at all. A common starting range for a small local business in Odisha is ₹25,000–₹50,000 a month, focused on a single channel.
Established with steady revenue
Now the percentage method works. Take your monthly revenue, apply 8–12%, and that's a sensible marketing budget. Split it between keeping current channels healthy and testing one new one.
Scaling and profitable
At this stage you should be spending based on how much profitable growth you can absorb. If every ₹1 you put into ads returns ₹4 in profit, the question isn't "what's my budget" — it's "how much can I spend before returns start dropping?"
The best-run businesses don't ask "what should I spend?" They ask "how much can I profitably spend?" — and then they spend right up to that line.
Agency fee vs ad spend — keep them separate
This trips up almost every business owner new to paid marketing. There are two completely different costs, and confusing them leads to bad decisions.
The hidden danger of spending too little
Most advice warns against overspending. But in my experience, underspending quietly kills more campaigns than overspending does.
Paid platforms need data to optimise. A budget too small to generate enough conversions never lets the algorithm learn, so it never performs — and the owner concludes "ads don't work for my business," when really the campaign was never funded enough to function.
If you can't afford the minimum viable budget for a channel, you're better off putting everything into one channel done properly than spreading a thin budget across three that all underperform.
